Abstract

Un material compuesto para electrodo negativo, que comprende un material compuesto Si-MC. En la superficie del material compuesto Si-MC se encuentra una capa conductora, donde M comprende al menos uno de los siguientes elementos: boro, nitrógeno u oxígeno. El desplazamiento químico del silicio en el material compuesto Si-MC, determinado mediante resonancia magnética nuclear de estado sólido, comprende los rangos -5 ppm ± 5 ppm, -35 ppm ± 5 ppm, -75 ppm ± 5 ppm y -110 ppm ± 5 ppm; y el ancho a media altura del pico K a -5 ppm ± 5 ppm cumple con la condición 7 ppm < K < 28 ppm. El material compuesto para electrodo negativo descrito en esta solicitud presenta una baja tasa de expansión y una alta conductividad eléctrica. La lámina de electrodo negativo y el dispositivo electroquímico descritos en esta solicitud presentan un buen rendimiento cíclico. (Traducción automática con Google Translate, sin valor legal)
