Lithium Ion Battery - An Overview

Li-ion or Lithium-ion batteries have gradually become the pivotal means of storing energy for off-grid solar products. Lithium-ion batteries have been gaining momentum due to their low cost yet high efficiency, lack of effect on memory, high capacity and long lifecycle.

Li-ion is one of the ever-evolving technology that was first introduced in the 1990s and still now there is ongoing research to boost performance, enhance safety and extent its lifetime. 

Li-ion batteries have several characteristics that are perfectly suited for best use in off-grid applications. These batteries usually have a long lifecycle and they don’t have a high rate of self-discharge and memory effect of NiMH and NiCD batteries. 

The charging power of Li-ion batteries is extremely good and it sometimes even reached 99% for few Li-ion chemistries. 

Lithium-ion battery and how it works

A lithium-ion or Li-ion battery is a part of the latest battery technology that utilizes lithium ions as one of the main fundamentals of its electrochemistry. When there is a discharge cycle, the lithium atoms present in the anode are ionized and in the process they are separated from the electrons. 

In a li-ion battery, the lithium ions move from the anode and pass via the electrolyte till they reach the cathode. In the cathode, they again combine with electrons and neutralize electrically. 

The lithium ions are pretty small to move via a micro-permeable separator between the cathode and the anode. Due to the small size of lithium, third to helium and hydrogen, they are able to hold a high voltage and charge storage per unit volume and unit mass. 

Li-ion batteries can utilize various materials in the form of electrodes. However, the most used and common one is of graphite (anode) and lithium cobalt oxide (cathode). This combination is mostly found in portable electronic gadgets like laptops and cellphones. 

Other materials of cathode can comprise of lithium iron phosphate or lithium manganese oxide. Li-ion batteries usually use ether as electrolyte. 

Li-ion Batteries –What are the benefits?

As against other premium quality technologies of rechargeable battery, Lithium-Ion batteries usually have several advantages. Here are few of the benefits you should take note of.

• Li-ion batteries have high density of energy among any other battery technology at present (100-265 Wh/kg or 250-670 Wh/L).
• The cells of the Li-ion battery can deliver around 3.6 volts, which is thrice higher than technologies like Ni-MH or Ni-Cd. This also implies that they can deliver more amount of current for applications. 
• Li-ion batteries are low maintenance batteries and they don’t need scheduled cycling for retaining the life of the battery. 
• Li-ion batteries don’t have any memory effect which is a detrimental procedure constant charge/discharge cycle will lead to the battery to ‘remember’ a lower capacity. This is a huge benefit against Ni-Cd and Ni-MH battieres. 
• Li-ion batteries have low self-discharge rate of 1.5-2% in a month. They don’t have toxic cadmium and this makes it easier for the batteries to dispose of rather than Ni-Cd batteries. 

Thanks to all the above mentioned benefits that Li-ion batteries have replaced Ni-Cd batteries and taken the place of market leader in electronic gadget market. 

Li-ion batteries are used to turn on electrical systems for aerospace applications like the Boeing 787 where one of the noteworthy cost factors is weight. 

From the perspective of clean energy, the promise of Li-ion technology arises from possible applications in cars powered by battery.

Presently, if you take into account the best-selling electric cars, the Tesla Model S or the Nissan Leaf, you’ll find that both of these use Li-ion batteries as the main source of fuel. 

Li-ion Batteries – Few Pitfalls

In spite of the technological claims, there are still few shortcomings, especially when safety is concerned. 

1. Li-ion batteries tend to overheat and may be damaged at high voltages.
2. In few cases, this leads to combustion and thermal runaway. 
3. Due to such issues, shipping companies often hesitate to carry bulk shipments via flight. 
4. Li-ion batteries need safety mechanism to restrain internal pressure and voltage. This can often increase the weight of the batter and limit its performance.
5. The cost of Li-ion batteries is 40% higher than Ni-Cd batteries.

Therefore, if you want to use the latest battery technology, go for Lithium-ion batteries as their advantages outnumber the disadvantages.

Security as a Matter of Concern: What Is the Best Encrypted Messenger?

Where do we spend most of our time? What do we do? We're online, browsing, and texting each other. On business, on personal matters, on whatever matters can be. Are we private while doing this? World experts claim that for 100% No.

If you think that there is no one who is interested in you and your personal info, you are deeply mistaken. There are hundreds of institutions, corporations, cybercriminals whose prime aim is to dig, intercept, thieve and use your data for their purposes for - to feed you with targeted ads, to use your passwords, to read the content of your chats.

That's naturally that with time, people started to develop and use the services, which are to protect your personal data, correspondence and hide the traces of online presence.

Why did we start to use encryption?

To secure the content we share. Usually, messengers use end-to-end encryption. This type of encryption means that only users participating in the dialogue have access to messages. 

The server transferring the data cannot decrypt the content, and even if the central server is hacked, it is protected. However, since the source code of almost all instant messengers is closed, the use of E2EE has to be swollen for granted.

The best solution, in this case, is the combination of modern encryption techniques with the decentralized architecture.

Signal vs. Silent Phone: What is the best encrypted messenger?

It's believed that Signal and Silent Phone are the two most secure messengers for the time being.

Signal

It's an app for instant messages exchange. It uses open cryptographic protocols for strong encryption and secure data transfer. Thus, it uses the Signal Protocol end-to-end encryption algorithm developed by OWS, which is quite popular among other messengers now.

To make sure that it is your interlocutor who is holding the smartphone, and not someone else, the Safety Number option will help. On top of all, the password protection function of the messenger will help to protect the information on your device from prying eyes.

It's free, and there are no ads, and the devs promise that there are no chances for them to appear. The convenience is added thanks to the ability to set it as the default call and SMS app.

Silent Phone

That's a newly introduced messenger of Silent Circle - a company specialized in data protection, created by former Navy SEALS. To become their client, you have to buy their secure smartphone ($800), which shows a really impressive safety level, or to install their app on Android/iOS.

Developers guarantee the transfer of data in their services directly from client to client in encrypted form using the peer-to-peer principle. It is almost impossible to intercept information or decrypt it.

Mentioning the Silent Circle company, I want to emphasize that it has developed its own network. To be able to communicate with each other, customers must be registered in it or have the necessary smartphones and special applications. 

The offered app is free for download, but you have to pay $9,95 for a monthly subscription. That's quite a little for personal freedom and security. And given that the big brother often invades our personal lives, then the very possibility of complicating his task is worth it.

Or you can wait for some activists to create a similar open-source project that all can use.

Which one to call the best encrypted messenger? You tell. Each of them still has its strengths and weak points. But the industry doesn't stay still, new messengers and other solutions for security appear on the market. Our task is not to stop searching for a flawless messenger.

Windows Privacy Concerns, Learn Why You Should Use A VPN

A Virtual Private Network (VPN) helps in creating a secured connection to another network over the Internet.  Virtual Private Network (VPN) is actually a paid service with the help of which it becomes possible to keep your web browser security.

With a secured VPN connection it becomes possible to connect your PC, smartphone, tablet, etc. to the server and it also permits you to browse Internet using secure Internet connection.

Hence, VPN software thatworks perfectly on Windows acts as a secure tunnel between the PC and destination which you need to visit on the Internet.

Reasons for Using VPN

Apart from establishing a secured online connection between two or more computers, there are various reasons for using a VPN. These reasons are mentioned as follows.

• Browsing the Web securely on Public Wi-Fi: You may get free Wi-Fi when you go to shopping complexes, parks, railway stations, etc. It is a natural tendency for people to get online as soon as they get free Internet. Accessing the Internet without a VPN can be a very risky matter. With free Wi-Fi you can easily get into trap as fake Internet connection that operates as a pleasant face can be a phishing scam.

• Beating location-based streaming restrictions: There can be a location-based restriction in streaming the website. For example, you may be in the UK and want to streamed releases on the US version Netflix. But if you install a VPN and specify a local server you will be able to securely connect to and route data. Hence even if your computer is in the United States of America it can be connected to the server that is there in the United Kingdom.

• Defeating oppressive Government Censorship:  Government of a country sometimes prevent you from accessing certain websites especially when you want to access other country’s website. But at times it becomes necessary to communicate to the outside world. In such a case you can easily use VPN to access the materials as well as services that you may need to use without any security. In VPN every data is encrypted which means all your online actions are private.

• Saving money on online shopping: VPN can also help you to save money on online shopping. For example, if you observe the product of an online retail store you will find that its price varies from country to country. Hence if you want to purchase the product from another country where it costs you can save a lot of money. But this can only become possible only by using a VPN.

• Saving money on airfares: You may also be able to save a lot of money by purchasing air tickets from different countries with a VPN. Airfares can be different from country to country even if the departure and destination remain the same. For example, it is observed carefully you will find that air ticket is cheaper via a Norwegian IP address rather than that of Malaysian IP address. If you have a VPN connection you will be able to purchase your air ticket from that country where the cost is low.

• Encrypting everything automatically: Whatever online activities you perform via VPN everything is encrypted. Even if you send an important message or confidential email via VPN there is no risk of cyber theft as the data will be totally encrypted. A secure and private tunnel is created for sending you data. Thus public Wi-Fi can also be safe and how data, as well as browse activity, will be kept from the eyes of government censors.

• Enjoying private and secured voice chat: With the help of a VPN, it becomes possible to keep the video and voice chat secured. There are some chat apps that do not have built-in encryption. For example, chat over Voice over IP (VOIP) does not have built-in encryption. That is the reason why whenever you will use voice chatting app like Skype, Google, Hangout, etc. should not be used without VPN connection. Apart using VPN the speed of the chatting will also increase considerably.

Due to the above-mentioned reasons, the use of VPN becomes very vital for every company that can protect from any kind of risk.

Making Social Welfare Students Job-ready For The Private Sector

Students of TSWREIS or Telangana Social Welfare Residential Educational Institutions Society, the department of education, are opting for every possible measure in order to seek admission into the premier and top-notch national colleges of India for the last years. 

TSWREIS has finally come to the conclusion that it is not possible for every student to crack the IIT entrance examinations. Hence, they have introduced the novel scheme with an eye to bringing improvement in employment in the private sector.

For those students who are studying in 11th class in specific schools across the state, more than fourteen vocational courses are recognized in different areas like taxation, medical lab technician, hotel and retail management, physiotherapy, office assistantship, pre-primary school teacher, pharmacy.

Scopes of employment

R.S. Praveen Kumar, the Society secretary stated that they offer training to the children for cracking Government jobs since their ninth grades. At the same time, they have realized that the private sector requires immense manpower in different skills and areas which cannot be developed in the due course of time. 

The new education policy demands education since early childhood. They offer assistance to the students in finding out the most suitable job for them.

The society secretary, however, ensures that the scheme is not specifically for each and every student who is willing to go for full time higher education. It is however for those students who intend to pursue higher education but fail to do so owing to poverty. 

Thus, the vocational courses are primarily to connect students who belong to poor families and seek employment for earning bread and butter for the family. These courses will be useful to them in pursuing higher studies and earn for the family at the same time.

Almost 2200 students showed their interest for taking interest in the course out of which 1380 students have made enrollments in them in certain institutes as off now. However, there are high chances that the programs will be expanded to almost every high school in the near future. 

The society secretary also emphasized on the importance of the development of pre-primary schools with the prerequisite funding from SC corporation and similar agencies in the long term. 

It opens doors of job opportunities for students and let them become an entrepreneur as they set schools on their own in the process, once they complete the training.

School garages

The Society is found to tie with the Society for Employment Promotion and Training in Twin Cities or SETWIN for starting the School Garages in which students will seek training in Mobile Phone technology. 

As they take part in the training, they will learn different options for repairing the electronic gadgets of the new age. In accordance with the society secretary, they are allocating space in different schools which will help the students in learning more about those technologies.

Consolidation phase

At present, society is into the consolidation phase of the existing infrastructure. It has gained success in recruiting 3,000 teachers within the time duration of one year. In the process, more than four hundred lecturers will be recruited for the colleges, offering degrees to women.

More than twenty thousand girls have successfully completed their courses from these colleges who else would have got married. The Society secretary also added with pride that few of these women also gained success in entering to the Tata Institute of Social Studies with an eye to pursuing different postgraduate programs.

At the time of conducting the course, if the students require any assistance with the essay writing course, they can opt for the services of Rapid Essay. It stands second to none in resolving the specific issues at the time of writing.
