High-performance magnesium-air primary battery with nitrogen-doped nanoporous graphene as air electrodes

In pursuit of a carbon-neutral society, advancement of the battery technology becomes imperative. Primary batteries, though non-rechargeable, hold promise as power sources for sensors and disaster scenarios because of their cost-effective production and voltage stability. However, most of these batteries employ expensive metal electrodes, such as lithium electrodes, necessitating exploration of alternative electrode materials.
