BATTERY AND ELECTRONIC DEVICE COMPRISING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18099725 titled 'BATTERY AND ELECTRONIC DEVICE COMPRISING SAME
Simplified Explanation
The abstract describes a battery design that includes a positive electrode, a negative electrode, and a separator.
- The positive electrode has a substrate with a positive active material applied to one surface, and a positive electrode tab attached to that surface.
- The negative electrode has a substrate with a negative active material applied to one surface, and a negative electrode tab attached to that surface.
- The first surface of the negative electrode substrate has a region without the negative active material, facing the positive electrode tab.
- The first surface of the negative electrode substrate also has a region with the negative active material, adjacent to the first region in the longitudinal direction of the positive electrode tab.
- The negative electrode includes an insulating layer in at least a portion of the first region.
Potential applications of this technology:
- This battery design can be used in various electronic devices, such as smartphones, laptops, and electric vehicles.
- It can also be applied in renewable energy storage systems, like solar power or wind power storage.
Problems solved by this technology:
- The design helps prevent short circuits between the positive and negative electrodes.
- It reduces the risk of damage to the battery caused by contact between the positive electrode tab and the negative active material.
Benefits of this technology:
- The insulating layer in the negative electrode helps improve the safety and reliability of the battery.
- The design allows for efficient energy storage and discharge, enhancing the overall performance of the battery.
- It can potentially extend the lifespan of the battery by minimizing the occurrence of short circuits and damage.
