MIT electrolyte enables ultra-high voltage Ni-rich cathodes in Li-metal batteries

Green Car Congress

The electrolyte not only suppresses side reactions, stress-corrosion cracking, transition-metal dissolution and impedance growth on the cathode side, but also enables highly reversible Li metal stripping and plating on the lithium-metal anode (LMA), leading to a compact morphology and low pulverization. —Jeremiah Johnson.

Hybrid biomass flow battery stores electricity and produces valuable chemicals at the same time

Green Car Congress

Rechargeable batteries store electricity in their electrode materials, while redox flow batteries use chemicals stored in tanks attached to the electrodes. A rechargeable biomass battery was designed to integrate electricity storage/generation and electrosynthesis of useful chemicals from furfural in one system. Resources Li, J.,

Penn State team devises solution for fast charging of Li-ion batteries at cold temperatures

Green Car Congress

Fast charging is seen as a solution for range and recharging time issues for EVs. However, a critical barrier to fast charging is temperature. Now, a team from Penn State has devised an approach that enables 15-min fast charging of Li-ion batteries in any temperatures (even at ? C charge at 10 °C and C/1.5

Researchers show that layered calcium transition metal oxides can be promising cathode materials for Ca-ion batteries

Green Car Congress

Out of several candidates that could replace Li in rechargeable batteries, calcium (Ca) stands out as a promising metal. Not only is Ca 10,000 times more abundant than Li, but it can also yield—in theory—similar battery performance.

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. This is due to the lack of electrocatalysts that successfully reduce and generate oxygen during the discharging and charging of a battery. Other two amorphous bimetallic, Ni 0.4 O x and Ni 0.33
