A startup Japanese company called Power Japan Plus have announced a new type of rechargeable battery which they claim is a significant improvement compared to LiIon batteries. The battery was developed at the department of applied chemistry at the Kyushu University in Japan.
The press release suggests that vehicles equipped with the battery would have a 300 mile range, indicating a better energy density than LiIon batteries. They also claim that the battery can be recharged twenty times faster than LiIon and can be cycled more than 3000 times without loss of capacity.
If that doesn’t tick enough boxes they also go on to say that the battery does not produce any significant temperature rise during operation so there is no need for additional cooling and no risk of thermal runaway. Details of the design are sketchy but they state that the only active material used in the battery is carbon, making it cheap to manufacture. The battery is described as using an organic electrolyte where positively charged lithium ions flow to the anode and negatively charged anions flow to the cathode, which would suggest other elements are also at play. The design is said to be 100 % recyclable. Power Japan Plus are currently focussing their research on a new type of carbon-complex battery made entirely from organic carbon.
