Sodium-ion based full cell and method of fabricating electrodes for the sodium-ion based fuel cell
Problem Statement

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.

Abstract

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.

Uniqueness of the Solution
  • 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.
Prototype Details

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.

Current Status of Technology
