ELECTROLYTE FOR LITHIUM-ION BATTERIES WITH SILICON-BASED ANODES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17851135 titled 'ELECTROLYTE FOR LITHIUM-ION BATTERIES WITH SILICON-BASED ANODES
Simplified Explanation
Abstract: An electrochemical cell is described in this patent application. The cell consists of an anode made of a silicon-based active material, a cathode made of a cathode active material, and an electrolyte. The electrolyte is formulated using a propionate-based solvent, a carbonate-based solvent, trifluoro toluene, a lithium salt with a molar concentration of 2.0 M or greater, and less than or equal to 5.0 wt. % of fluoroethylene carbonate.
Patent/Innovation Explanation:
- An electrochemical cell is designed with specific components and electrolyte formulation.
- The anode is made of a silicon-based active material, which is likely to enhance the performance of the cell.
- The cathode is made of a cathode active material, which could be a different material than the anode.
- The electrolyte is formulated using a combination of propionate-based solvent, carbonate-based solvent, trifluoro toluene, and a lithium salt with a high molar concentration.
- The electrolyte also contains a small amount (less than or equal to 5.0 wt. %) of fluoroethylene carbonate, which may have a specific purpose in improving the cell's performance.
Potential Applications:
- This technology could be used in various electrochemical devices, such as batteries or fuel cells.
- It may find applications in portable electronics, electric vehicles, renewable energy storage, and grid-scale energy storage systems.
Problems Solved:
- The use of a silicon-based active material in the anode may address issues related to low energy density and limited capacity in traditional anode materials.
- The specific electrolyte formulation could potentially improve the overall performance and stability of the electrochemical cell.
Benefits:
- The use of a silicon-based active material in the anode may result in higher energy density and increased capacity of the electrochemical cell.
- The specific electrolyte formulation may enhance the cell's performance, stability, and lifespan.
- This technology has the potential to contribute to the development of more efficient and reliable electrochemical devices.
