Abstract

A presente revelação se refere a uma célula de bateria, um módulo de bateria, um conjunto de bateria, um dispositivo que utiliza a célula de bateria como fonte de alimentação e um método para montar a célula de bateria. A célula de bateria compreende uma montagem de eletrodo (20) e uma placa de suporte isolante (50), a montagem de eletrodo (20) compreende uma porção de corpo principal (22) e abas (21) conectadas à porção de corpo principal (22), a placa de suporte isolante (50) compreende uma primeira porção de suporte (51) e segundas porções de suporte (52) conectadas à primeira porção de suporte (51), a primeira porção de suporte (51) se projeta, em relação às segundas porções de suporte (52), em uma direção próxima à porção de corpo principal (22) de modo que primeiras folgas sejam formadas entre as segundas porções de suporte (52) e a porção de corpo principal (22), e pelo menos partes das aba (21) estejam localizadas nas primeiras folgas. As primeiras folgas formadas entre as segundas porções de suporte e a porção de corpo principal podem acomodar pelo menos partes das abas, protegendo efetivamente as abas, evitando que as abas sejam comprimidas, reduzindo danos às abas e prolongando a vida útil da bateria.
