We aim to promote the Nickel-zinc (Ni-Zn) battery technology to a higher level. In comparison to the lithium-ion battery, our Ni-Zn is safer, contains no toxic or flammable material, less expensive, requires less complex control electronic, easier to recycle, easier to install in terms of the risk assessment, and has less dependency on strategic materials. Moreover, it has attractive features such as high power density, which makes it suitable choice for high drain applications, or wider operating temperature range (than lithium-ion).
