“…It should be emphasized that we are speaking of a jump in the ac resistance rather than in the voltage drop. It can be suggested that this behavior is related to a phenome non that is inverse to the so called baro emf [3], i.e., results from the strain sign reversal at the interface. The significant jump that accompanies the voltage sign reversal at 0.55 V can, in our opinion, also be related to weakening of the mechanical contact in a multilayer structure of the supercapacitor.…”
