  "textContent": "A negative electrode material includes a composite of a silicon-based material (), a polymer (), and carbon nanotubes (), where the polymer () contains a first group and a second group, the first group is chemically bonded to the carbon nanotubes (), and the second group is chemically bonded to the silicon-based material (). Both the carbon nanotubes () and the polymer () containing two groups are applied to surfaces of particles of the silicon-based material (). The two groups of the polymer () are chemically bonded to the silicon-based material () and the carbon nanotubes () respectively, so that bonding force between the silicon-based material () and the carbon nanotubes () is enhanced and a uniform carbon nanotube () coating layer is formed. This can significantly improve conductive performance of the silicon-based material (), thereby improving cycling performance and rate performance of an electrochemical apparatus.",
