Traditional sodium-ion batteries can be unsafe due to dendrite formation, which can lead to short circuits and fires. Additionally, existing production methods are often slow and expensive.
This invention describes a new method for producing a safe and scalable anode material for sodium-ion batteries. The method offers a significant improvement over existing techniques by providing a faster, more cost-effective way to create high-performing batteries.
- Utilization of silica sand coated with materials like glucose or coal-tar.
- Pre-sodiation technique to balance electrode capacities.
- Scalable production methods increase material yield by 2.5 times compared to previous patents.
- Enhanced safety and lower production costs due to the use of low-cost components.
- Dendrite-free battery design using carbon nanofiber with ether-based electrolytes.
The prototype includes a negative electrode material produced via the described method, capable of yielding 65 grams of anode material and 30 grams of cathode material per liter of solution.
The technology is at an advanced development stage, with the production process scaled up significantly. It has been optimized to address safety and efficiency issues commonly associated with sodium-ion batteries.
