  "textContent": "A negative electrode includes: a negative electrode current collector and a negative electrode active material layer located on at least one surface of the negative electrode current collector. The negative electrode active material layer includes a negative electrode active material, where the negative electrode active material includes graphite and hard carbon. Based on a total mass of the hard carbon, a ratio of a mass of element hydrogen to a mass of element carbon in the hard carbon is W, and based on a total mass of the graphite, a ratio of a mass of element hydrogen to a mass of element carbon in the graphite is W, a value of W/Wbeing within a range of 5 to 19. The electrochemical apparatus has reduced impedance and improved rate performance and cycling performance.",
