Successfully fabricated air zinc batteries, store electricity 5 times more than lithium-ion batteries

Chemical engineers at the University of Sydney and Singapore's Nanyang Technological University have successfully developed the "zinc-air" rechargeable battery technology that can be applied to electronic devices instead. for lithium - ion batteries like today.

According to Professor Yuan Chen - the author of this study - air zinc batteries were formerly produced by expensive metal components such as Platinum and Iridium Oxide, thus being applied only in a very limited way. on small electronic devices such as hearing aids or train signals.

This new study offers a new solution, which replaces expensive components by lower-cost but high-performance components, produced through component and size control. , and metal Oxides crystallization such as iron, cobalt, nickel. Therefore, this new air-zinc battery could "overcome the development of slow oxygen and oxygen reduction reactions (OER / ORR) in many electrical energy conversion devices" - the study notes.

Air zinc batteries work on the principle of zinc oxidation by air.

The new battery test also showed positive results, with a 10% battery pack after 60 cycles of charging / disconnecting within 120 hours. Since then, it is possible to see its applicability to mobile electronic devices.

"Our approach is to create low-cost, high-performance components that are used in battery making. We are continuing to solve some other minor issues related to technology to be able to create these. more durable metal battery for people " - Dr. Li Wei, co-author said.

Air zinc batteries are a type of battery in the air metal family, operating on the principle of zinc oxidation by air. The battery is cheaper to manufacture than lithium-ion batteries (extremely popular batteries used on today's electronic devices), storing 5 times more electricity than lithium ion batteries and much more environmentally friendly.

Meanwhile, lithium ion batteries are lighter and more efficient at generating energy, so they are widely used on smartphone devices, or even electric vehicles manufactured by Tesla. However, lithium ion batteries contain materials that are compressed under high pressure and are easily flammable, which in turn can have unfortunate consequences when the battery is touched inside the circuit. An example of this is the battery error on the Samsung Galaxy Note 7, causing the device to explode and eventually being killed by Samsung itself. In a recent report, Samsung said its lithium ion batteries were faulty, resulting in a circuit break and the engine.

Some other batteries can replace lithium ion like magnesium batteries , with the strong point of not being "bottled" by overcharging, or graphene batteries that are often used in high-level electrode structures.
