"With the green transition toward adopting renewable energies, a safe and reliable energy storage system is needed to store the intermittent renewable energy sources.

Our proposed invention offers a rainwater-based aqueous electrolyte that could be deployed as a promising stationary rechargeable energy storage system. A unique formulation is added to rainwater to form the aqueous-based electrolyte, which enables the superior electrochemical performances of the cell. The prototype batteries in the form of coin cell and pouch cell formats have been demonstrated in the lab.

Technology features:
 Constructed based on green and sustainable materials.
 Aqueous-based electrolyte enables superior fire safety.
 Concocted electrolyte formulation enables cells with high-rate capability and superior cycle stability.
 Facile cell assembly/disassembly in an ambient environment with a hassle-free maintenance process.
