Abstract

CÉLULA DE BATERIA, BATERIA, APARELHO ELÉTRICO, MÉTODO DE FABRICAÇÃO DE CÉLULA DE BATERIA E SISTEMA DE FABRICAÇÃO DE CÉLULA DE BATERIA. As formas de realização deste pedido fornecem uma célula de bateria, uma bateria, um aparelho elétrico e um método de fabricação e sistema de célula de bateria. A célula de bateria inclui um invólucro, um conjunto de eletrodos e um conjunto de cobertura de extremidade. O invólucro fornece uma abertura. O conjunto de eletrodos é disposto no invólucro. O conjunto de eletrodos inclui uma porção de corpo, uma aba e uma porção de isolamento. A aba se estende de uma extremidade da porção de corpo até a abertura. A porção de isolamento está disposta em uma periferia da aba. O conjunto de cobertura de extremidade é configurado para fechar a abertura. O conjunto de cobertura de extremidade inclui uma cobertura de extremidade e um primeiro isolante. A cobertura de extremidade é configurada para cobrir a abertura e é conectada ao invólucro. O primeiro isolante está disposto em um lado da cobertura de extremidade mais próximo do interior do invólucro. O primeiro isolante tem uma porção côncava. Pelo menos parte da aba é acomodada na porção côncava. O primeiro isolante é configurado para encostar na porção de isolamento para isolar a aba do invólucro. A célula de bateria nas formas de realização deste pedido visa resolver curto-circuito da célula de bateria que afeta a segurança de uso.
