Li-Polymer
(Lithium Polymer)
A battery technology similar to Lithium-ion.
Current "lithium-polymer" batteries are technically "lithium ion polymer", since pure lithium-polymer batteries are not yet commercially viable. Pure lithium-polymer batteries, once available, will theoretically provide considerable benefits over current battery technologies.
Today's lithium-ion polymer batteries perform similarly to lithium-ion batteries, but can be made much thinner - as thin as 1mm.
