| 发明名称 | Method for producing negative electrode material for lithium ion batteries | ||
| 摘要 | A negative electrode material for lithium ion batteries is obtained by a method which includes: mixing carbon particles (B) such as graphite particles, particles (A), such as Si particles, containing an element capable of occluding and releasing lithium ions, a carbon precursor such as sucrose, a carboxylic acid compound such as acetic acid, and a liquid medium such as water or isopropyl alcohol to prepare a slurry; drying and solidifying the slurry; and heat-treating the resulting solidified material to carbonize the carbon precursor. A lithium ion battery is obtained using this negative electrode material. | ||
