Lithium-Ion Batteries Collaborative Hand Books ( A123, Dewalt, etc.)
Lithium-ion batteries (sometimes abbreviated Li-ion batteries) are a type of rechargeable battery commonly used in consumer electronics. They are currently one of the most popular types of battery for portable electronics, with one of the best energy-to-weight ratios, no memory effect and a slow loss of charge when not in use. They can be dangerous if mistreated, however, and unless care is taken their lifespan may be reduced. Although originally intended for consumer electronics, Lithium-ion batteries are growing in popularity with the defense and aerospace industries because of their high energy density.
A more advanced lithium-ion battery design is the lithium polymer cell.
