Abstract

"BATERIA DE LìTIO RECARREGáVEL USANDO UM SEPARADOR PARCIALMENTE RECOBERTO COM UM GEL POLìMERO". Descreve-se um separador para uma bateria que é recoberto com um polímero de gel sobre 40-60% da área total do separador e uma bateria de lítio recarregável que usa tal separador. O separador parcialmente recoberto com um polímero de gel reduz a resistência da bateria de forma que a potência da bateria pode ser melhorada. Adicionalmente, o separador aumenta a taxa de impregnação de eletrólito e provê impregnação uniforme de eletrólito, enquanto melhora a vida útil, capacidade e propriedades de alta taxa de descarga de uma bateria. Além do mais, o separador permite a execução uniforme das reações dos eletrodos, prevenindo assim a precipitação de lítio e melhorando a segurança de bateria.
