Abstract

1/1 resumo "células eletroquímicas com conjunto aprimorado de eletrodo enrolado em espiral" trata-se de um conjunto de eletrodo enrolado em 5 espiral, uma célula eletroquímica com o conjunto de eletrodo enrolado em espiral e um método de fabricação de uma célula eletroquímica com o conjunto de eletrodo enrolado em espiral. o conjunto de eletrodo enrolado em espiral (400) tem um primeiro eletrodo (410) que tem um primeiro material 10 ativo de eletrodo, uma borda anterior e uma borda posterior (440). o conjunto tem um segundo eletrodo (420) que inclui um segundo material ativo de eletrodo, uma borda anterior e uma borda posterior (450). um separador (não mostrado) está localizado entre o primeiro eletrodo e o segundo eletrodo. o 15 conjunto de eletrodo tem uma razão interfacial entre cátodo e ânodo menor do que cerca de 1,2. o primeiro eletrodo, segundo eletrodo e separador são enrolados de modo que o primeiro eletrodo forme uma camada no raio mais externo do conjunto de eletrodo e de modo que a borda posterior do 20 segundo eletrodo se estenda além da borda posterior do primeiro eletrodo por uma distância x.
