Abstract:
The present application relates to the electrochemical field, and in particular, to a negative electrode plate and a secondary battery including the electrode plate. The present application provides a negative electrode plate. The negative electrode plate includes a negative electrode current collector, a first negative electrode active substance layer disposed on at least one surface of the negative electrode current collector, and a second negative electrode active substance layer disposed on the first negative electrode active substance layer. The first negative electrode active substance layer includes a first negative electrode active substance, and the second negative electrode active substance layer includes a second negative electrode active substance. The first negative electrode active substance satisfies 1 GPa≤Young's modulus≤10 GPa, and the second negative electrode active substance satisfies 11 GPa≤Young's modulus≤30 GPa.
