ELECTRODE PLATE, BATTERY CELL, BATTERY AND ELECTRICAL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18446290 titled 'ELECTRODE PLATE, BATTERY CELL, BATTERY AND ELECTRICAL DEVICE
Simplified Explanation
The patent application describes an electrode plate for a battery cell, along with a battery and an electrical device that use this electrode plate.
- The electrode plate consists of an insulating substrate, a conductive layer, and an active material layer.
- The conductive layer is placed on the insulating substrate, and the active material layer is applied on top of the conductive layer.
- The conductive layer has two parts: one part is coated with the active material layer, and the other part is not coated.
- Both parts of the conductive layer are arranged in a specific direction.
- The conductive layer has certain properties, including resistivity, specific heat capacity, and density, which are used to calculate a constant value.
- The thickness of the conductive layer and the size of the coated part must satisfy a specific range of values.
- The purpose of this invention is not explicitly stated in the abstract.
Original Abstract Submitted
An electrode plate, a battery cell, a battery and an electrical device are provided. The electrode plate includes an insulating substrate, a conductive layer, and an active material layer. The conductive layer is arranged on the surface of the insulating substrate. The active material layer is applied on the surface of the conductive layer away from the insulating substrate. The conductive layer includes a first part coated with the active material layer and a second part not coated with the active material layer. The first part and the second part are arranged along the first direction. The conductive layer has a resistivity of ρ1, a specific heat capacity of C, a density of ρ2, and a constant K=ρ1/(C·ρ2). The conductive layer has a thickness of d1, the first part has a size of W along the first direction, and d1, W and K satisfy: 0.001 J/(Ω·mm·° C.)≤d1/(K·W)≤0.0075 J/(Ω·mm·° C.).
