We need to talk about lead‑acid battery grids

Frequent cycling is the focus of research in lead-acid battery design today— a group of leading lead-acid battery researchers got together at the recent BCI meeting in Florida to discuss innovation in grid design. Boris Monahov reports.

High-Rate Partial-State-of-Charge (HRPSoC) cycling of lead-acid batteries in novel applications like hybrid electric vehicles, renewable power sources and grid storage is becoming the norm. 

And valve-regulated lead‑acid (VRLA) batteries subjected to HRPSoC cycling lose their capacity very fast due to preliminary selective sulphation of the negative plates.
