Abstract

bateria cilíndrica, e, veículo. são descritos na presente invenção uma bateria cilíndrica, que compreende: um alojamento, em que o alojamento é dotado de um espaço de acomodação; e uma camada de placa negativa, uma primeira camada de separador, uma camada de placa positiva e uma segunda camada de separador, que são sequencialmente empilhadas e bobinadas em múltiplas camadas para definir um núcleo de polo. o eixo geométrico do alojamento é colinear com aquele do núcleo de polo. o núcleo de polo é pelo menos parcialmente acomodado no espaço. a camada de placa positiva compreende uma camada de material positivo e uma camada de folha positiva. a camada de placa negativa compreende uma camada de material negativo e uma camada de folha negativa. pelo menos parte da camada de folha positiva, que é bobina em múltiplas camadas, se estende em direção a uma extremidade do alojamento para formar uma aba positiva. pelo menos parte da camada de folha negativa, que é bobina em múltiplas camadas, se estende à outra extremidade do alojamento para formar uma aba negativa, de modo que a parte de uma face de extremidade positiva do núcleo de polo que não é coberta pela aba positiva esteja localizada em pelo menos um lado da aba positiva, e a parte de uma face de extremidade negativa do núcleo de polo que não é coberta pela aba negativa esteja localizada em pelo menos um lado da aba negativa.
