Abstract

La présente invention concerne une électrode négative pour une batterie rechargeable. L'électrode négative pour une batterie rechargeable selon la présente invention comprend un collecteur de courant d'électrode négative et un matériau actif d'électrode négative accumulés sur au moins une partie de la surface du collecteur de courant d'électrode négative. De multiples rainures de collecte de courant de prévention de désinsertion dans lesquelles est accumulé le matériau actif d'électrode négative sont formées dans le collecteur de courant d'électrode négative. Le matériau actif d'électrode négative est formé sur les surfaces latérales internes des rainures de collecte de courant de prévention de désinsertion de telle sorte que des parties d'espace ayant des couches de diffusion de masse formées en leur sein sont formées dans les rainures de collecte de courant de prévention de désinsertion pendant un processus de charge/décharge.
