Japan Start-Up Creates Revolutionary Carbon Battery

Researchers in Japan have announced they have developed a longer-lasting, safer, faster charging battery that also costs less than a regular lithium-ion battery. The new battery, created by a start-up company in Japan, employs carbon for both the anode and the cathode poles.

Lithium-ion batteries are widely used in smartphones, flashlights and electric cars. But this new battery, says the Power Japan Plus company, can be discharged thousands of times without diminishing its capacity, can generate more power and can be recharged about 20 times as fast as standard lithium-ion versions. The company said its battery is rated for more than 3,000 recharge cycles, and promoted the idea that its product could operate over years in harsh environments, such as inside medical devices or in space.

Dou Kani, CEO of Power Japan Plus, said in a statement that his company "is a materials engineer for a new class of carbon material that balances economics, performance and sustainability." He added that the product, called the Ryden dual carbon battery, "is the energy storage breakthrough needed to bring green technology like electric vehicles to mass market."

'Unique Properties'

Such a battery could dramatically change the charging calculations of, say, a Tesla car, which has a large lithium-ion battery pack. On its Web site, Power Japan Plus said its battery could enable a 300-mile range electric vehicle on one charge. Additionally, the company said that regenerative braking, which recaptures energy, would be more efficient in cars using its technology.

In a battery, the electrolyte between the anode and the cathode conducts ions that generate electrons, and thus electricity. The new version could be safer because it doesn't use lithium oxide, which is flammable. Punctured lithium-ion batteries can readily catch fire.
