Getting Closer to a Consumer Magnesium Rechargeable Battery

October 20, 2021 | Leave a Comment

A Tohoku University research team has developed liquid-sulfur/sulfide composite cathodes that enable high-rate magnesium batteries. Magnesium rechargeable batteries show immense promise for a greener future because of their energy density, safety, and cost. But the lack of high-performance cathode materials has impeded their development. Magnesium rechargeable batteries (MRBs), where high-capacity Mg metal is used as […]

Battery Chemistry Idea Solid State Silicon Works Quite Well

September 28, 2021 | Leave a Comment

University of California – San Diego engineers have created a new type of battery that weaves two promising battery sub-fields into a single battery. The battery uses both a solid state electrolyte and an all-silicon anode, making it a silicon all-solid-state battery. The initial rounds of tests show that the new battery is safe, long […]

Add Sugar to Sulfur To Beat Lithium Ion Batteries

September 14, 2021 | Leave a Comment

Monash Energy Institute has created a longer-lasting, lighter, more sustainable rival to the lithium-ion batteries simply by adding sugar. The new battery performance level is essential for aviation, electric vehicles and submarines. The Monash team, assisted by CSIRO Manufacturing, report in Nature Communications that using a glucose-based additive on the positive electrode they have managed […]

Polymer Electrolytes Solve A Solid State Battery Problem

September 9, 2021 | Leave a Comment

A Pohang University of Science & Technology (POSTECH) joint research team succeeded in improving ionic conductivity using electrostatic interface of polymer electrolytes. The POSTECH research team recently developed a polymer electrolyte without a “dead zone” – which lowers ion transport – thus accelerating the commercialization of all solid state batteries. As the demand for electric […]
