Abstract
This application relates to a negative electrode material, a negative electrode using the material, an electrochemical apparatus, and an electronic apparatus. Specifically, this application provides a negative electrode material, including graphite, where the negative electrode material has an I-order lithium intercalation plateau potential P1 of 30 mV to 75 mV and an II-order lithium intercalation plateau potential P2 of 90 mV to 110 m V The use of the negative electrode material of this application can significantly improve the cycling performance of the electrochemical apparatus using the negative electrode material under high voltage and high temperature, enhance the gram capacity of the negative electrode material, while maintaining the initial efficiency of the negative electrode material.
