OCV hysteresis in nickel metal hydride batteries
Abstract: NiMH batteries exhibit a hysteresis, or path dependence, regarding the rest voltage of the system. Depending on charge/discharge history of the battery the rest voltage will be found between two boundary values for each state of charge. Most of this phenomenon seems to arise from the positive NiOH electrode, which is a proton intercalation electrode and changes structure between charged and discharged states. A possible explanation for the different material characteristics at the same system state could be small changes in the structure depending on the charge/discharge history. This experiment aims to track any structural changes in the disordered Ni(OH)2/NiOOH system at the same state of charge but with different charge/discharge paths.
