ACTIVE MATERIAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240234721 titled 'ACTIVE MATERIAL
The present disclosure focuses on providing an active material that suppresses expansion upon intercalation of a metal ion such as a Li ion.
- Active material comprises a silicon clathrate type crystal phase.
- Active material includes a Na element, a Si element, and a metal element (M) with an ion radius larger than the Si element.
- Proportion of the M element to the total of the Si element and the M element is between 0.1 atm % and 5 atm %.
- Potential Applications:**
- Energy storage in batteries - Electric vehicles - Portable electronic devices
- Problems Solved:**
- Expansion of active material upon intercalation of metal ions - Improved stability and performance of batteries
- Benefits:**
- Enhanced battery performance - Longer lifespan of batteries - Increased energy storage capacity
- Commercial Applications:**
Title: Advanced Battery Technology for Energy Storage Solutions This technology can be utilized in the development of high-performance batteries for various applications, including electric vehicles, renewable energy storage systems, and portable electronics.
