Sustainable Batteries

In the realm of sustainable batteries, two promising innovations have emerged: Fiber Batteries, leveraging renewable plant-derived cellulose for eco-friendly energy storage, and Shell Batteries, inspired by the regenerative abilities of crustaceans. These technologies signal a future where energy storage is not only cost-efficient but also environmentally harmonious.


Abundant biomaterials provide great cost-efficiency for raw materials


Highly stable solid-state electrolyte ensures superior performance in applications


Derived from natural materials, bio-degradable, green and sustainable


Outstanding performance delivers reliable use life and safety for energy storage

the Most Abundant Biomaterials

Nanocellulose, derived from cellulose, stands as one of the most abundant biomaterials on Earth. This remarkable substance, composed of nanoscale cellulose fibrils, is sourced from various plant-based materials, including wood and agricultural residues. Its widespread availability, combined with its exceptional mechanical properties and eco-friendly attributes, positions nanocellulose as a versatile and sustainable material with applications spanning industries such as packaging, textiles, and even advanced electronics. 

As we continue to harness the capabilities of nanocellulose, we unlock innovative pathways toward reducing our environmental footprint and advancing technology in harmony with nature. This abundant biomaterial holds the promise of a more sustainable and environmentally conscious future across various sectors of industry and research.

Li-Cu-CNF Fast Ion Conductor

Fiber Battery

The cellulose battery represents a pioneering leap in energy storage technology. With its quasi solid-state electrolyte, it boasts a dense, thin, and highly conductive design, ensuring stable operation even in the presence of Li anodes and cathodes. Remarkably, it achieves the highest ion conductivity among polymer electrolytes, thanks to its ion-conducting fiber that facilitates rapid ion transport.


The battery's 1D fiber conductor enables efficient ionic percolation, while its thick electrode configuration ensures high energy density. Additionally, its ability to support fast charging makes it a standout solution in the quest for efficient and sustainable energy storage.

Zinc Shell Battery

The innovative crab-zinc battery leverages an unexpected source of sustainability - seafood waste. By extracting chitin from discarded crab shells and processing it into chitosan-zinc electrolytes, this battery not only repurposes a typically discarded resource but also offers remarkable advantages.


In terms of cost-effectiveness and safety, zinc batteries outshine commercial Li-ion counterparts, making them a top choice for grid storage applications. What's more, the robust supply chain security for zinc batteries, given the US's abundant reserves of key production elements, presents a promising solution to enhance energy storage in a sustainable and secure manner.
