Abstract

CÉLULA DE BATERIA, BATERIA E APARELHO ELÉTRICO. Este pedido fornece uma célula de bateria, uma bateria e um aparelho elétrico. A célula de bateria inclui: um conjunto de eletrodos, incluindo uma porção do corpo e uma primeira aba. Um primeiro tamanho (L1) da porção do corpo em uma direção do comprimento da mesma é maior do que um segundo tamanho (L2) da porção do corpo em uma direção da largura da mesma. A primeira aba está localizada em pelo menos uma extremidade da porção do corpo na direção da largura. A primeira aba tem um terceiro tamanho (L3) na direção do comprimento. O primeiro tamanho (L1), o segundo tamanho (L2) e o terceiro tamanho (L3) satisfazem 0,5L2 = L3 = L1. A célula de bateria de acordo com uma forma de realização deste pedido destina-se a resolver um problema técnico de geração de calor severa por uma aba.
