Traction battery: Types of lithium batteries

Primary Li cells - disposable, cannot be charged.
Charging leads to crystalline solid lithium structures, which can damage the separator and short-circuit the battery.
Li-ion - rechargeable batteries, only lithium ions Li +
Li-polymer - the same composition as Li-ion, the separator is replaced by a special polymer, more expensive than Li-ion
Li-air - high energy density, space programs
Small amount of atmospheric oxygen (20%)
Li-S, Na,…
