Description

Advantages of LFP batteries

High level of safety: Due to the cell chemistry, LFP cells are considered intrinsically safe, i.e. thermal runaway and membrane melting are prevented.
as with other lithium-ion batteries can be ruled out.
High mechanical safety due to the metal cylinder shape (similar to NiCd). The electrodes also contain no unbound oxygen atoms, which react violently chemically when released into the air.
Thanks to this fact, the nail penetration test according to UL 1642 is passed.
High cycle stability: 75 % residual capacity after 6 years at max. 55 °C (one discharge per month).
Low self-discharge, i.e. approx. 5 % per month compared to 30 % for NiCd and 35 % for NiMH).
Improved environmental compatibility due to the absence of heavy metals such as cobalt.
Over 50 % less space required thanks to smaller cells compared to NiCd and NiMH.
Lower procurement costs compared to NiMH batteries.
