dual-carbon battery

Dual-carbon batteries are a new energy storage technology that uses a form of carbon for both the anode and the cathode.

Power Japan Plus, who developed the technology, says their dual-carbon batteries (brand-named Rayden) are mostly made of carbon and use a lithium compound rather than the typical volatile lithium oxide for the negative terminal and an organic electrolyte for the positive.

The batteries are 100% recyclable and are further being developed to use carbon produced with organically-grown cotton.  The batteries charge 20 times faster than lithium ion batteries, a capacity that would make electric vehicles more convenient for daily use.  That rate would make it possible, for example, to charge a Tesla S in 90 seconds rather than a half-hour for a long distance trip.

According to Power Japan Plus, dual-carbon batteries also:

• Have 3000 charge cycles as compared to the 300 of lithium ion batteries.
• Are free from thermal runaway, making the batteries safer in charging and discharging.
• Don’t require cooling, saving power and complexity in many applications.
• Include no rare earth metals, which enables a lower cost and better price stability.
