Cambrian e-bike batteries with single carbon electrode cells from Japanese PJPEye promises a lifespan of over 10 years with over 8,000 lifecycles that are fully covered by warranty. QuickCharging™ technology allows you to reach full charging in only 20 minutes.
The dual carbon electrode cell was developed in 2014 by Power Japan Plus in a partnership with the Kyushu University in Fukuoka, Japan. In 2017, Hiroaki Nishina created a company to develop and put that technology into production. In 2018, he and his team managed to start selling a pouch cell with a single carbon electrode named Cambrian battery. Ever since, the single carbon electrode cell has been applied in electrically power-assisted bicycles.
According to the company, the single carbon electrode battery offers multiple advantages compared to the lithium-ion cells. The first one is that it charges very fast. While a similarly sized Li-ion needs four hours to be fully charged, the Cambrian battery needs only 20 minutes. PJPEye also says that the battery stands more than 8,000 cycles, so its service life is more than ten years. Lithium-ion batteries would endure only 1,500 cycles and its service life is between five to ten years. As toxic materials are not used to produce this battery, it does not require mining and is much cheaper to produce compared to regular batteries.
The main thing is that there is no heat produced so there is no explosion: Unlike lithium-ion batteries where there is oxygen inside rare metals, Cambrian batteries do not contain any oxygen inside so there is no risk of explosion. You may be able to bring it to the airplane and it’s not going to explode.
PJPEye plans to build an urban car that will be able to carry one or two people and some luggage. This company’s vehicles are quickly powered by Cambrian batteries, no matter they have a single or two carbon electrodes. Remember, the dual carbon solution is still under development, and it promises to be even better than one that is already for sale.
