Abstract
An electrochemical apparatus, including a positive electrode, a negative electrode, and an electrolyte. The negative electrode includes a negative electrode current collector and a negative electrode active substance layer formed on the negative electrode current collector. The negative electrode current collector has a high tensile strength and the negative electrode active substance layer has a specific weight. The electrochemical apparatus has improved high-temperature storage expansion performance and cyclic expansion performance.
