  • Negative electrode plate, testing method of active specific surface area of electrode plate, battery
    Patent number: 11283061
    Abstract: The present disclosure provides a battery and a testing method of an active specific surface area of an electrode plate. The battery comprises a positive electrode plate, a negative electrode plate, a separator and an electrolyte, the negative electrode plate comprises a negative current collector and a negative film, the negative film is provided on at least one surface of the negative current collector and comprises a negative active material, the negative active material comprises graphite, and an active specific surface area of the negative electrode plate is 1 cm2/g˜15 cm2/g. In the present disclosure, by reasonably controlling the active specific surface area of the negative electrode plate can make the battery have the characteristics of high energy density and excellent dynamics performance at the same time.
