Lithium-Ion-Battery – Industry Trends – Part 1

Part of the challenge in a product liability or personal injury case is understanding the factors contributing to product failure. This understanding can assist attorneys in selecting the appropriate expert witness.

An awareness of technical trends and “how things work” can be helpful to attorneys. To this end, we are running a series of posts on scientific topics; this week’s article is on lithium batteries.

Lithium-ion batteries are widely used in consumer electronics and all other applications requiring rechargeable batteries. This is a result of their excellent electrical performance, high energy density and long cycle life.  Lithium-ion batteries also have been demonstrated to have a good safety record and to be environmentally benign.  They have been widely used in portable electronic devices like cell phones, cameras, personal computers, power tools, and super capacitors, just to mention a few common applications.  Large lithium-ion batteries are being evaluated for use in electric automotive vehicles and standby power applications.
