How does a lithium-ion battery work What advantages does it have over a lead-acid battery When does lithium-ion battery storage pay off?

Answer 1

A lithium-ion battery (short: lithiumion battery or Li-ion battery) is the generic term for accumulators based on lithium compounds in all three phases, in the negative electrode, in the positive electrode as well as in the electrolyte, the electrochemical cell. Lithium-ion batteries have high specific energy compared to other types of batteries, but require electronic protection circuits in most applications, as they react adversely to both deep discharge and overcharge.

Lithium-ion solar batteries are charged with electricity from the photovoltaic system and discharged again as required. For a long time, lead batteries were considered the ideal solar power solution for this purpose. However, based on lithium-ion batteries have decisive advantages, although the purchase is still associated with additional costs, which are, however, recouped through targeted use.
