Cotton-Based Battery Could Lead to More Affordable EVs

May-16-14 A cotton-based organic battery could help promote EV use by allowing the vehicles to have more range and charge more quickly, making the vehicles as "common as Corollas."

Developed by the startup Power Japan Plus, the Ryden dual carbon battery is said to have an energy density comparable to a lithium ion battery, but it contains no rare earth metals, is safer, can be charged and discharged thousands of times with no loss in energy capacity and it can be charged 20 times faster.

The key to the battery's performance lies in organic cotton, which the team used to create what they call a Carbon Complex. The Carbon Complex makes up the anode and cathode of the battery, while an organic electrolyte is used as the conducing fluid—which also renders the battery completely recyclable. As Chris Craney, Power Japan Plus’s chief marketing officer, told the Atlantic: “To be bold, we are confident we are a major solution for the current electric vehicle industry.”
