POSITIVE ELECTRODE PLATE, SECONDARY BATTERY, BATTERY MODULE, BATTERY PACK AND POWER CONSUMING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18351998 titled 'POSITIVE ELECTRODE PLATE, SECONDARY BATTERY, BATTERY MODULE, BATTERY PACK AND POWER CONSUMING DEVICE

Simplified Explanation

The patent application describes a positive electrode plate for a secondary battery, as well as a battery module, battery pack, and power consuming device that utilize this electrode plate.

  • The positive electrode plate includes a positive electrode current collector and positive electrode film layers.
  • The positive electrode film layers can have a single-layer or multi-layer structure.
  • In the single-layer structure, at least one of the film layers contains a first and second positive electrode active material.
  • In the multi-layer structure, at least one layer contains the first and second positive electrode active materials.
  • The first positive electrode active material consists of LiMnAPRO, a first coating layer of crystalline pyrophosphate LiMPO and/or M(PO), a second coating layer of crystalline phosphate XPO, and a third coating layer of carbon.


Original Abstract Submitted

A positive electrode plate, a secondary battery, a battery module, a battery pack, and a power consuming device are described. The positive electrode plate include a positive electrode current collector and positive electrode film layers having a single-layer or multi-layer structure. When the positive electrode film layers have a single-layer structure, at least one of the positive electrode film layers comprises a first positive electrode active material and a second positive electrode active material; and/or when the positive electrode film layers have a multi-layer structure, at least one layer of the at least one of the positive electrode film layers comprises the first and second positive electrode active materials; the first positive electrode active material comprises an inner core LiMnAPRO, a first coating layer comprising crystalline pyrophosphate LiMPOand/or M(PO), a second coating layer comprising crystalline phosphate XPO, and a third coating layer; and the third coating layer is carbon.
