Rechargeable Lithium Batteries (Li-Ion Batteries)

Lithium-Ion batteries (a.k.a., Li-Ion batteries) are the most popular lithium battery designs. In particular, there is a growing demand for Lithium batteries featuring 18650 cells, which have found their way into diverse consumer products—from cell phones and laptops to power tools, vehicles, high-powered LED torches, and doorbells.

Some of the advantages that make Li-Ion battery cells so popular include their high energy density, low maintenance design, low self-discharge rates, and high maximum continuous-discharge rate (depending on the cell).

To find out which Lithium-Ion battery cell type is best suited to your needs, talk to SIMPOWER battery specialists today.
