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 relativamente 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.
