High voltage when charging NiMH battery?
Other cells jump very high. Even over 3 V. And if I leave the charge for several seconds the voltage will slowly drop. But I never leave them charging like that. This occurs even if the battery is already trickle charged as described above. I separated out every battery with this behavior from the batteries that have "normal" behavior.
Kinetics of oxygen reaction and discharge/charging overvoltages of …
It is found that the catalyst does not affect either the oxygen reduction kinetics or the Li-O 2 battery discharge overvoltage. At the same time, the charging overvoltage of a Li-O 2 battery with the catalyst is found to be lower than that of a Li-O 2 battery with the carbon material. It is shown that the latter effect is maybe more related to ...
