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.
