ELECTRODE ASSEMBLY, SECONDARY BATTERY, AND ELECTRIC DEVICE

Resumen de: EP4604194A1

The present application relates to an electrode assembly, a secondary battery, and an electrical apparatus. During the design process, the width of the negative electrode plate is designed to be greater than the width of the positive electrode plate. At the same time, the width difference between the negative electrode plate and the positive electrode plate is correlated with the extension ratio of the negative electrode plate, such that the upper limit value of the width difference between the negative electrode plate and the positive electrode plate does not exceed (4.5 - M1 × a). Thus, it can be seen that using the product of the extension ratio a and the width of the positive electrode plate as a subtractive term reduces the upper limit value of the width difference. Such a designed electrode assembly during cyclic charging and discharging will not experience excessive width of the portion of the negative electrode plate extending beyond the positive electrode plate due to extension of the negative electrode plate. This can effectively alleviate lithium plating within the overhang region between the negative electrode plate and the positive electrode plate, thereby enhancing the reliability of the secondary battery.
