Title:
NEGATIVE ELECTRODE FOR LITHIUM SECONDARY BATTERIES, NEGATIVE ELECTRODE PRECURSOR FOR LITHIUM SECONDARY BATTERIES, LITHIUM SECONDARY BATTERY, AND METHOD FOR PRODUCING NEGATIVE ELECTRODE FOR LITHIUM SECONDARY BATTERIES
Document Type and Number:
WIPO Patent Application WO/2024/084937
Kind Code:
A1
Abstract:
This negative electrode for lithium secondary batteries is formed of a rolled material of aluminum or an aluminum alloy, the rolled material being capable of absorbing and desorbing lithium ions; and if two cycles of measurement at a heating rate of 10°C/minute for the range of 30°C to 500°C are performed in the differential scanning calorimetry of this negative electrode for lithium secondary batteries and ∆DSC is the value obtained by subtracting the amount of heat generation in the second cycle from the amount of heat generation in the first cycle, the integral value of the ∆DSC for the range from 100°C to 300°C is 0.5-8 mW/g or less.
