A modified lithium-ion battery cathode material, cathode and battery

A modified negative electrode material, negative electrode and cell of lithium ion cell, the negative electrode material made of modified quasi one dimension nano carbon material with average diameter of 1nm-500nm which is 0.1 %-50 % of total weight of negative electrode material selected from natural graphite, intermediate phase char microsphere, amorphous carbon, hard carbon, pyrolytic carbon, petroleum coke, asphalt base carbon fiber etc carbon material, and one or plurality of kinds of stannum base and silicon base material. Said invention raises the service life, charge capacity and discharge rate and effectively improves the performance of lithium ion cell.
