The nickel hydroxide electrode is known to exhibit a stable hysteresis loop, with the potential on charge being higher than that on discharge at every state-of-charge ~SOC!. What we show here is that this loop created during a complete charge and discharge ~i.e., boundary curves ! is not sufficient to define the state of the system. Rather, internal paths within the boundary curves ~i.e., scanning curves! can be generated that access potentials between the boundary curves. The potential… CONTINUE READING
