Abstract

1/1 resumo "conjunto de tampa para uma célula eletroquímica" a presente invenção refere-se a um conjunto de tampa (26) para uma célula eletroquímica (10) que tem uma tampa (24), um coletor de corrente (20) e um lacre (22). o coletor de corrente (20) tem uma estrutura colunar (32) com uma cabeça (34) em uma extremidade da mesma. o lacre (22) tem uma saliência central (36) com uma abertura (38) através da qual o coletor de corrente (20) é inserido. o lacre (22) tem, também, uma borda periférica (40) e uma peça de conexão (42) que conecta a saliência central (36) à borda periférica (40). a superfície de topo (48) da saliência central (36) fica voltada para a superfície de fundo (50) da tampa (24) e a superfície de fundo (50) da saliência central (36) não se estende abaixo da superfície de fundo (46) da peça de conexão (42). o coletor de corrente (20) é posicionado dentro da abertura (38) da saliência central (36), de modo que a cabeça (34) do coletor de corrente (20) não toca a superfície de topo (48) da saliência central (36) formando, dessa forma, uma lacuna de cerca de 0,01 mm a cerca de 0,50 mm entre a cabeça (34) do coletor de corrente (20) e a superfície de topo (48) da saliência central (36). a cabeça (34) do coletor de corrente (20) é eletricamente conectada à superfície de fundo (30) da tampa (24).
