The zinc-manganese alloy also allows replacement of the solvent typically used in
A battery stores energy in the form of chemical energy:with the help of a reaction it is converted into electrical energy, which powers vehicles, mobile phones, laptops and other devices. The battery consists of an anode and a cathode, usually made of different materials, there is also a separator and an electrolyte, this is a chemical medium that allows the electrical charge to pass through.
In a lithium-ion battery, as the name suggests, charge is carried by lithium ions as they move through the electrolyte from the anode to the cathode.
The electrolytes in lithium-ion batteries are usuallydissolve in organic solvents, which are highly flammable and often decompose at high operating voltages. Accordingly, there are security problems.

Water batteries are a promising alternative. Aqueous electrolytes are cost competitive, environmentally friendly, and fast charging and highly resistant to abuse.
Researchers from Oregon State UniversityCentral Florida and the University of Houston have developed an anode consisting of a three-dimensional "zinc-M alloy" as the battery anode, where M stands for manganese and other metals.
The alloy with its special nanostructure is not onlyinhibits dendrite formation, controls surface reaction thermodynamics and reaction kinetics, and exhibits ultra-high stability over thousands of cycles under harsh electrochemical conditions.
Scientists hope that their invention will be used in mass production.
