Storage advice: Avoid voltage drop in the lithium cells

4/12/19, 5:00 PM -

If the cell voltage drops below a critical limit, copper particles come loose from the metal film at the anode. These will fall into the electrolyte, where only lithium ions should be.

The solar systems are ready made for operation.

In this case, the additives in the electrolyte behave differently, the copper binds to the anode. Such a cell is also useless, even if it will not immediately catch fire.

Therefore, an on-board diagnostic system (OBD) is imperative, permanently documenting and analysing the operating data of the cells. Just one temperature sensor somewhere within the battery is not enough, because each cell is a sensitive link in the chain – as much as every solar panel in the string. (HS)
