Cells have been used for storing energy from time immemorial, from a Baghdad battery, which dates back to 250BC to newer technology such as a hydrogen fuel cell, that just gives water as a byproduct, batteries have come a long way. A group of cells when connected together review film is called a battery.

Batteries are touted as the future of energy storage for Electric Vehicles. Even the first cars, made in the year 1842 were powered by batteries, which is almost 2 decades before the invention of Internal combustion engine vehicles but the lack of range and slow charge rate caused the decline of Electric Vehicles in the 20th century. The growing environmental concern due to climate change has forced us to move towards renewable energy and adopt battery energy storage systems and the research and development of battery technologies kick-started.

In a country like India, more than a quarter of total pollution is caused due to automobiles. Till date the adoption of Electric Vehicles (EV) could not take off due to range anxiety, price, lack of infrastructure, and lack of choices. The research and development in Li-ion batteries in recent years have paved the way for EVs across the globe. We have previously discussed the basics of electric vehicle batteries in general. In this article we will be learning about different Li-ion chemistries, their advantages and disadvantages and compare them with few other rechargeable batteries.

Primary Cell and Secondary Cell
Primary cells are single-use, non-rechargeable cells, the ones we use in our TV remotes, wall clocks, etc. These are considerably cheaper while having high energy density, which means that they are smaller, weigh less and are more cost-effective. This makes them ideal choice for applications that require lower amount of energy as it helps cut down the cost as well as the weight of the final product.
