Abstract：
 This invention discloses a method for increasing electrochemical Li-storage capacity of carbon nm tubes, which processes the original MWNTS raw material prepared with chemical gas phase deposition method including: first of all, the original MWNTS is supersonic-vibrated, mechanical mixed and dipped under room temperature in different matched volumes of H2SO4 and HNO3 mixed solution, the reacted product is cleaned with deionized water to neutral and put in a tube oven to be heated under 200-500deg.C to be cooled and dipped in Li2CO3 or LiOH solution, the obtained sample is cleaned with deionized water, filtered and dried in vacuum. The gap of quasigraphite layer of the processed MWNTS is expanded, the electrochemical Li capacity is increased.
