Researchers of the U.S. Naval Research Laboratory (NRL) developed the nickel-zinc (Ni-Zn) batteries in which a three-imensional Zn “sponge” replaces positively charged electrode which is traditionally used.Zinc-based batteries are the global battery for single-use applications, but these are not considered rechargeable in practice due to their tendency to grow conductive whiskers (dendrites) inside the battery, which can produce long enough to cause short circuits.

Joseph Parke, lead author of the research paper published in the journal Science, “Electric currents are more uniformly distributed within the sponge, which making it physically difficult to form dendrites( conductive whiskers).

So now we are preparing an energy-relevant lithium-ion with new opportunities which has portable and wearable power, and manned and unmanned electric vehicles too, while reducing safety hazards, easing transportation restrictions, and using earth-abundant materials,” said Jeffrey Long from NRL.
