3. Failure mode for Ni-MH batteries
Nickel-metal-hydride battery performance degradation during use can arise from three causes intrinsic to the technology.
The first factor is related to the swelling of the positive electrode during the charging and overcharging phases, which leads to the formation of γ-type nickel oxyhydroxide (figure 9 ).
The second cause is the degradation...
