摘要

The electrochemical performance of two anode materials has been investigated in CLAiO's fully functional lithium-ion battery mockups. Our findings show that the spherodized purified natural graphite SL20 possesses sufficient reversible capacity and low irreversible capacity loss, and thus has been qualified as a suitable candidate material for application in lithium-ion batteries. Another carbon material investigated in this work was a Boron-doped carbon (25B2) synthesized by WUT via co-pyrolysis of coal tar pitch with pyridine borane complex. Its irreversible capacity was seen to be higher than that of SL20, while reversible capacity is promising. The unique electron acceptor properties, which are typical in boron-doped graphites did not manifest themselves in the investigated sample. Ball milling of boron-doped carbon may be an effective way of improving the WUT precursor and thus designing a suitable lithium-ion grade anode material.
