Lithium Batteries for storage

Lithium ion batteries are the most widely used batteries that we come across for energy storage. This was first discovered by chemist, M Stanley Whittingham at Exxon in the 1970s. The ideal storage conditions for a battery to operate are dependent on the active chemicals prevalent in the cell. These are very popular among small as well as medium based corporations and industries, also providing up a larger lifespan than the traditional batteries that were being used.

Lithium ion batteries have various benefits as they are light weight, high energy density power sources for a number of day to day appliances that we use. Now to provide power to larger devices, such as electric cars, connecting smaller batteries in a parallel circuit is very efficient and effective as compared to a single large battery in use. Such appliances consist of:

  • Portable devices: which consist of tablets, laptops, smart phones, mobile phones, camcorders etc.
  • Power devices: it includes cordless drills, saw etc which have lithium ion batteries for there working.
  • Electric vehicles: Electric vehicle batteries are used in automobiles, cars, scooters, bicycles etc.

The worldwide production of lithium ion batteries was nearly 660 million in the year 2012. As of 2016 statistics the global market of production of lithium ion batteries capacities was estimated to be around 28 gigawatt hours with China occupying the maximum share of the entire market with nearly 16.4 gigawatt hours.

Lifespan of a lithium ion battery is ideally explained as the number of full charge-discharge cycles to reach a failure threshold in terms of capacity loss or impedance rise. Manufacturers’ datasheet typically uses the word “cycle life” to specify lifespan in terms of the number of cycles to reach 80% of the rated battery capacity.
