Abstract

BATERIA SECUNDÁRIA DE ELETRÓLITO NÃO AQUOSO E MÉTODO DE FABRICAÇÃO DA MESMA. A presente invenção refere-se a uma bateria secundária de eletrólito não aquoso (100) que inclui: uma folha coletora de corrente de eletrodo negativo (21); e uma camada de mistura de eletrodo negativo (22) que é disposta na folha coletora de corrente de eletrodo negativo. A camada de mistura de eletrodo negativo contém uma pluralidade de partículas granuladas. Cada uma das partículas granuladas contém um material ativo de eletrodo negativo (2) e um filme de revestimento (4). O filme de revestimento é formado em uma superfície do material ativo de eletrodo negativo. O filme de revestimento inclui um primeiro filme (4a) e um segundo filme (4b). O primeiro filme é formado na superfície do material ativo de eletrodo negativo. O segundo filme é formado no primeiro filme. O primeiro filme contém um polímero de carboximetilcelulose. O segundo filme contém um polímero de ácido poliacrílico.
