Algae transform polymer-cellulosic batteries

Edit Hook

Cellulosic batteries will incorporated conductive polymers to form essentially a paper battery. Current battery technologies are seriously flawed, and continued demand for rare-earth metals will only exacerbate cost issues. Adding weight and low toxicity to the benefits column, polymer-cellulosic batteries have a lot to offer. Problems with surface area for charge storage hampered research until the Angstrom lab thought to look at Cladophora algae for inspiration.

Key Differentiators

The battery produced using this process has extremely low weight, and has set records for charge-time and capacity for polymer-cellulosic batteries. Large scale production seems feasible. The batteries would be environmentally friendly, cost-effective, and lightweight forms of energy storage. Much research has been done in the area of cellulosic batteries, but nobody had yet focused on algal cellulose.

Biomimicry Story

Cladophora is a very common type of green algae, which blooms throughout the Baltic and around the world. It has a unique cellulosic cell structure with a very high surface area. Algal cellulose actually has a fundamentally different nanostructure from terrestrial plant cellulose. This forms an excellent template for surface modification to include a conducting polymer. By looking to nature, the Angstrom Lab’s scientists were able to clear a substantial hurdle in the field of polymer-cellulose batteries.

Challenges Solved

Charging performance weakness in cellulosic batteries; weight of metal ion batteries; environmental consequences of traditional batteries; cost of ionic solutes.
