Some of the most vexing problems associated with EVs regard battery range, charging time, and life-cycle limitations driven by non-standard use. However, at least two of these objections may be resolved, if Japanese-owned and operated Power Japan Plus (PJP) has anything to say about it.
According to the company, PJP has recently perfected a new battery technology named the dual-carbon system. The packaging integrates less expensive carbon anode and cathode components, while allowing charging rates of up to 20 times faster than traditional lithium-ion batteries.
Along with higher cycle rates, the new technology also experiences no thermal change when discharging. This advantage principally offers the complete elimination of external cooling systems that are typically seen as integral to current EV battery power-packs.
Although the new dual-carbon technology offers similar electrical densities when compared with competing lithium-ion components and, therefore, does not offer any extended-range value, the system does offer faster charging, along with enhanced service-life.
For example, the typical Nissan Leaf currently projects an empty-to-full charge cycle of 4 hours, while the new dual-carbon system will only require 12 minutes. At the same time, PJP’s technology accepts complete ‘0/0’ discharge unlike typical batteries, which utilize electrical ‘governors’ that avoid complete discharge that, in the event, reduces battery life-cycle.
The future of the new system appears to be bright, although the manufacturer suggests that it intends to sell the units in only two direct markets; the satellite communications and medical device segments. Nevertheless, the technology is already compliant with current generations of 18650 cell packaging, so once the system is on the shelf, vehicle manufacturer’s will be able to access and apply the technology for future EV purposes.
