This abstract first appeared for US patent application 18167065 titled 'POSITIVE ELECTRODE PLATE, SECONDARY BATTERY AND PREPARATION METHOD THEREOF AND BATTERY MODULE, BATTERY PACK AND POWER CONSUMING DEVICE COMPRISING THE SECONDARY BATTERY

==Simplified Explanation==

The patent application describes a positive electrode plate for use in batteries.
* The positive electrode plate includes a positive electrode current collector, a positive electrode active material layer, and a lithium supplementing layer.
* The lithium supplementing layer is composed of a lithium-rich metal oxide, a conductive agent, and a binder A.
* The binder A is a polymer that contains two different monomer units, shown by formula I and formula II.
* The monomer units can have various substituents and are selected from hydrogen or C1 to C8 alkyl groups.
* The positive electrode plate aims to improve the performance and capacity of batteries by providing a lithium supplementing layer.
* The use of a lithium-rich metal oxide in the supplementing layer helps increase the lithium content in the battery.
* The conductive agent and binder A ensure good conductivity and adhesion within the electrode plate structure.


==Original Abstract Submitted==

A positive electrode plate is provided. The positive electrode plate comprises a positive electrode current collector, a positive electrode active material layer provided on at least one surface of the positive electrode current collector, and a lithium supplementing layer provided on a surface of the positive electrode active material layer opposite to the positive electrode current collector. The lithium supplementing layer comprises a positive electrode lithium supplementing material, a conductive agent and a binder A, the positive electrode lithium supplementing material comprises a lithium-rich metal oxide, and the binder A is selected from polymers containing a first monomer unit shown by a formula I and a second monomer unit shown by a formula II, where the R, R, R, R, Rand Rare each independently selected from hydrogen or substituted or unsubstituted C1 to C8 alkyl, and the R is selected from substituted or unsubstituted C1 to C8 alkyl.
