Abstract
A battery includes active material containing neutral carbon radical compound at one of or both of the electrodes, and the neutral carbon radicals participate in electrode reaction for generating current; the battery is light, because any heavy metal is not required for the active material, and the battery achieves large capacity without sacrifice of stability, because the unpaired electrons are localized at the carbon atoms in the neutral carbon radical compound.
