Abstract
The present application provides a hard carbon, a preparation method, a secondary battery, and an electrical apparatus. Based on the total mass of the hard carbon, the total mass ratio of water-soluble cations in the hard carbon does not exceed 500 ppm. The hard carbon can improve the viscosity of a negative electrode slurry and can improve the cycle performance of a battery.
