Energy Storage System (ESS) opportunities are highly sensitive to the Levelised Cost of Storage (LCoS). Lead batteries are a fundamentally low-cost battery technology but economic opportunities have been restricted due to the limited cycle life at high depths of discharge. ArcStore, a highly re-engineered lead battery has achieved an approximately sixfold lifetime increase over a traditional lead battery under an extreme duty cycle 100% depth-of-discharge cycling (BCIS-6) in third party testing.  ArcStore batteries incorporate two core technologies; bipolar battery architecture and fabric structured electrodes. These technologies allow the four key failure modes that normally limit life to be managed providing a high capacity throughput with a low cost construction, thus proving a low LCoS.

This presentation will focus on;

• The four key failure modes that must be managed to achieve high capacity throughput with high active material utilisation (hence low product costs)


• How ArcStore manages these failure modes


• Cycle life test data


• The ArcStore manufacturing processes
