ELECTROCHEMICAL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18627672 titled 'ELECTROCHEMICAL DEVICE
The abstract describes an electrochemical device with a cell and a shell enclosing it. The cell consists of a jelly roll with a first electrode, a second electrode, and a separator between them. The electrodes are wound to form the cell.
- The first electrode includes a first current collector with a coated region containing a first active material and an uncoated region with alternating bent and straight portions.
- The bent portions of the uncoated region have an insulating layer for protection.
Potential Applications: - Energy storage systems - Electric vehicles - Portable electronics
Problems Solved: - Improved energy storage efficiency - Enhanced safety with insulating layers
Benefits: - Higher energy density - Longer lifespan - Safer operation
Commercial Applications: - Battery technology for electric vehicles - Energy storage solutions for renewable energy systems
Questions about the technology: 1. How does the insulating layer in the bent portions of the uncoated region improve the performance of the device? 2. What are the specific advantages of using a jelly roll design in this electrochemical device?
Frequently Updated Research: - Ongoing studies on enhancing the energy storage capacity of similar electrochemical devices.
Original Abstract Submitted
An electrochemical device, including a cell and a shell enclosing the cell; the cell includes a jelly roll including a first electrode and a second electrode spaced from each other, a separator is disposed between the first electrode and the second electrode, the first electrode and the second electrode are wound to form the cell; the first electrode includes a first current collector, the first current collector includes a first surface and a second surface disposed oppositely; the first surface faces the shell, and includes a coated region coated with a first active material and an uncoated region; the uncoated region includes a first uncoated region disposed at an end of the jelly roll, and the first uncoated region includes alternating bent portions and straight portions; and the bent portions are provided with an insulating layer.
