At high-rate discharge mode, the sulfation reaction occurs at the surface of the electrode due to kinetic limitations and the non-uniform potential and current distribution across the electrode. As a result, a large amount of lead sulfate is formed besides being charged during regenerative braking, which does not convert back to lead. This premature loss occurs due to
