In this paper, a high energy ball milling method is used to prepare ultrafine TiC powder using toluene and pure titanium. After two step ball milling, nanolevel TiC powder with higher purity is obtained, which is used as a negative electrode material to assemble a lithium ion battery to test the lithium battery performance, the results show that the ball milled TiC anode exhibits relatively excellent lithium battery performance, and its discharge capacity can still maintain 140mAh/g after 3000 cycles. The small particle size and the toluene residue in the ball milling reaction affect the negative electrode particles during the charge and discharge process. Although the performance of TiC itself is not very good for lithium batteries, its long cycle performance is excellent, and the results show that it cannot only be used as a framework material for Si anode. TiC can also be used alone as a negative electrode material.

For each impurity removal experiment, in addition to the investigation of the corresponding molar ratio, usually 0.005 mol lead and nickel nitrates, equimolar amount of CaCO 3 and 15 mL ultra pure water were added into the pots for wet ball mill activation at certain milling speed and running time under ambient temperature and pressure. After ...
2 and WC impurities in the product after primary ball milling. After calcination and secondary ball milling, TiH 2 impurities are removed and the TiC grain size is reﬁned, and TiC powder is obtained with a grain size of 12.5nm. The speciﬁc discharge capacity of the TiC anode is stable during the long cycle discharge.
