  "textContent": "A core-shell composite negative electrode material is made according to a preparation method and includes an application thereof. The composite negative electrode material includes: a core formed by a first active substance and a second active substance, and a carbon-coated shell serving as a third active substance. The first active substance is a sheet-like silicon-based material, the second active substance is a sheet-like graphite material, and the third substance is the carbon-coated shell. The composite material is applied to the negative electrode of a lithium ion battery, and has high specific capacity, wherein the capacity is greater than 400 mAh/g, and excellent cycle life.",
