BATTERY MODULE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240204240 titled 'BATTERY MODULE
The abstract describes a battery module consisting of positive and negative electrode members, each with current collectors and active material layers, as well as a separator. The negative electrode current collector and positive electrode current collector have folded-back portions. The first negative electrode active material layer forms a first electrode with the first positive electrode active material layer, while the second negative electrode active material layer forms a second electrode connected in parallel with the first electrode along with the second positive electrode active material layer.
- Positive and negative electrode members with current collectors and active material layers
- Separator separating the electrodes
- Folded-back portions on the current collectors
- Formation of first and second electrodes with active material layers
- Parallel connection of the second electrode with the first electrode
