Graphene Cages Could be the Key to Silicon Anodes

Battery boffins are buzzing about silicon anodes, which could store up to 10 times more energy than today’s anodes. The catch is that silicon particles tend to swell and crack during cycling, and to react with the electrolyte in unwanted ways. Now a team from Stanford University and the Department […]
