Abstract

célula de bateria. a presente invenção refere-se a uma célula de bateria que compreende um alojamento flexível, um primeiro e segundo eletrodos, um eletrólito e pelo menos uma região de vedação. o alojamento flexível inclui uma vedação de perímetro em que o alojamento é vedado em torno de seu perímetro. cada um dentre o primeiro e o segundo eletrodos compreende uma primeira região e uma segunda região que se projeta a partir da primeira região, em que a primeira e a segunda regiões do primeiro e do segundo eletrodos estão situadas dentro do alojamento flexível. o eletrólito está situado entre a primeira região do primeiro eletrodo e a primeira região do segundo eletrodo. as primeiras regiões do primeiro e do segundo eletrodos e do eletrólito são dispostas para definir uma zona eletroquímica alojada dentro do alojamento flexível. as segundas regiões do primeiro e do segundo eletrodos se projetam a partir da zona eletroquímica. a pelo menos uma região de vedação compreende uma região na qual as superfícies internas do alojamento flexível são vedadas juntas. a pelo menos uma região de vedação é disposta entre as primeiras regiões do primeiro e segundo eletrodos e a vedação de perímetro e é disposta para impedir o eletrólito de deixar a zona eletroquímica.
