University of Sydney team advances rechargeable zinc-air batteries with bimetallic oxide–graphene hybrid electrocatalyst

Green Car Congress

University of Sydney team advances rechargeable zinc-air batteries with bimetallic oxide–graphene hybrid electrocatalyst. Cheaper to produce than lithium-ion batteries, they can also store more energy (theoretically five times more than that of lithium-ion batteries), are much safer, and are more environmentally friendly.

U Waterloo team shows four-electron conversion for Li-O2 batteries for high energy density; inorganic molten salt electrolyte, high temperature

Green Car Congress

The new work, published in Science , shows that four-electron conversion for lithium-oxygen electrochemistry is highly reversible. The Waterloo team is the first to achieve four-electron conversion, which doubles the electron storage of lithium-oxygen, also known as lithium-air, batteries. Resources. —Xia et al.

Georgia Tech team develops conversion-type iron-fluoride Li battery cathode with solid polymer electrolyte

Green Car Congress

Researchers at Georgia Tech have developed a promising new conversion-type cathode and electrolyte system that replaces expensive metals and traditional liquid electrolyte with lower cost transition metal fluorides and a solid polymer electrolyte. A paper on their work is published in the journal Nature Materials.

Electric or hydrogen cars – which makes more sense for NZ?

Drive Electric

FCEVs utilise the stored Hydrogen and combine it with oxygen from the air to generate electricity. This electricity is then used to propel the vehicle’s electric motor and recharge its battery. There is also a need to address the potential safety risks of handling and storing Hydrogen. Read more on How FCEVs work?
