Title:
ELECTRODE ASSEMBLY, BATTERY CELL, BATTERY, AND ELECTRIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/045418
Kind Code:
A1
Abstract:
An electrode assembly, a battery cell, a battery, and an electric apparatus, which belong to the technical field of batteries. The electrode assembly comprises a negative electrode plate (221) and a positive electrode plate (222). The negative electrode plate (221) comprises a negative electrode active material layer (2211), and the negative electrode active material layer (2211) is provided with a first liquid storage tank (2212). The positive electrode plate (222) comprises a positive electrode active material layer (2221), the positive electrode active material layer (2221) and the negative electrode active material layer (2211) are arranged opposite each other in a first direction, the positive electrode active material layer (2221) is provided with a second liquid storage tank (2222), and the second liquid storage tank (2222) and the first liquid storage tank (2212) are arranged opposite each other in the first direction. The electrode assembly using this structure can store an electrolyte to increase the liquid retention capacity of the negative electrode plate and the positive electrode plate, such that the electrolyte in the first liquid storage tank and the second liquid storage tank can be quickly released during a discharging process, so as to infiltrate the negative electrode active material layer and the positive electrode active material layer in a surrounding area, thereby guaranteeing that the negative electrode plate and the positive electrode plate are fully infiltrated, and thus reducing the risk of lithium plating of the electrode assembly.
