Abstract
ânodo para bateria secundária. é descrito um ânodo para baterias secundárias compreendendo uma combinação de um material ativo de ânodo tendo uma tensão relativamente baixa de carga/descarga e uma dureza relativamente baixa (a) e um material ativo de ânodo tendo uma tensão retivamente alta de carga/descarga e uma dureza relativamente alta (b), em que o material ativo de ânodo (a) tem sua superfície revestida com carbono tendo uma dureza alta ou um compósito do mesmo, e o tamanho de partícula do material ativo de ânodo (b) é menor que o tamanho de um espaço formado pelos materiais ativos de ânodos (a) dispostos em uma coordenação quatro. o ânodo proporciona um elétrodo que evita a precipitação de lítio causada pelo excesso de tensão, aumenta a condutividade iônica bem como a condutividade elétrica e apresenta uma capacidade superior.
