Do li-ion batteries need protection circuits?

Protection circuits for Li-ion packs are mandatory. (See BU-304b: Making Lithium-ion Safe) More information on why batteries fail, what the user can do when a battery overheats and simple guidelines using Lithium-ion Batteries are described in BU-304a: Safety Concerns with Li-ion.

What is a lithium-ion battery?

A lithium-ion (Li-ion) battery is a type of rechargeable battery that belongs to the family of lithium-ion batteries. The term refers to the chemistry used in these batteries, which is an active area of research and new materials are constantly being developed.

Which cars use lithium-ion batteries?

A few cars that use lithium-ion batteries have recently entered the U.S. market including the Tesla Roadster, Nissan Leaf, and Chevrolet Volt. Lithium-ion battery powered vehicles have also entered overseas markets.

Can a lithium slice be used as a battery anode?

The large volume change in a cell with a lithium anode is also an unsolved problem. Thus, a proper manufacturing process with strict control of an atmosphere with little oxygen is essential to fulfill the production of a lithium slice as a battery anode.

What are lithium-ion batteries used for?

If you've read our main article on batteries, you'll know a battery is essentially a chemical experiment happening in a small metal canister.

Can a liquid electrolyte increase the energy density of lithium-ion batteries?

However, simply substituting a liquid electrolyte with a solid electrolyte cannot increase the energy density of lithium-ion batteries. Metallic lithium and its composite are essential to act as the cell anode to improve the energy density. However, lithium itself is unstable and leads to new possible battery failure modes.
