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 mixture layer formed on the negative electrode current collector, and the negative electrode mixture layer includes a negative electrode active substance. An elongation at a yield point of the negative electrode mixture layer and D50 of the negative electrode active substance satisfy a specified relationship, and the electrolyte includes a compound having a cyano group.
