Abstract

método de preparação de um catodo para uma bateria secundária. é aqui provido um método para preparar um catodo com base em uma pasta fluida aquosa. a pasta fluida de catodo compreende um material ativo do catodo, especialmente um material ativo do catodo contendo níquel, com estabilidade melhorada na água. o pré-tratamento de materiais ativos do catodo contendo níquel pode melhorar a estabilidade do catodo por impedir a indesejável decomposição do material. além do mais, as células de bateria compreendendo o catodo preparado pelo método aqui descrito exibem desempenhos eletroquímicos impressionantes.
