Storage advice: Safety first by ceramic separators inside

9/11/19, 5:00 PM -

Particularly reliable lithium cells contain a ceramic separator. It physically isolates the lithium cathode from the anode (made of graphite or copper, for example).

This storage system is contained in cast aluminium.

The separator prevents both electrodes from shorting. If the battery cell becomes older or is charged at low temperatures with very high currents, so-called dendrites can form within it. Dendrites are needle-like thorns of lithium that bridge the gap between the electrodes. Without a separator, a short circuit can result, which can cause the cell to overheat. (HS)
