In theory, if you replaced a lot of graphite in the cell with silicon, the thickness of the graphite negative electrode could be reduced.

理论上，如果用硅大量取代石墨，石墨阴极就可能变细，从而扩大容纳活性材料的空间。

The first commercial lithium-ion battery, launched by Sony in 1991, was a rocking-chair design that used cobalt oxide for the positive electrode, and graphite (carbon) for the negative one.

1991年， Sony 发布了第一款商用锂离子电池，它采用的就是摇椅式设计，其中用钴氧化物做正极，石墨（ 碳 ）做负极。

Particulate of graphite electrode wastes from an electric-carbon materials factory was formed "core-shell" negative materials by chemical deposition coating with medium pitch.

以大功率石墨电极废品破碎后的微粒为“核”，以中温沥青为包覆原料，经化学沉积包覆形成“核-壳”型锂离子蓄电池负极材料。
