Compared to other Ni-Zn technologies, our system provides higher power density, longer shelf life, better charge retention, much better low-temperature performance, and significantly lower material cost. All of these advantages can be attributed to eVionyx's patented membrane technology, which Xellerion has exclusive rights to for Nickel-Zinc batteries. The company therefore expects to enjoy advantages in both performance and cost against other Ni-Zn batteries.
