Aluminium-Air Batteries to replace Li-Ion battery Soon?

Get Electric Vehicle

Lithium-ion batteries have a profound role in triggering the EV revolution going on now. The ingenious idea to incorporate Li-ion batteries transformed electric vehicles from boring and lame to thrilling and exhilarating. Another concern is that ‘what to do with the Li-ion batteries once their lifetime is over?’

Carbon nanomembrane prevents dendrite formation in Li-metal batteries, doubles lifetime

Green Car Congress

The energy density of traditional lithium-ion batteries is approaching a saturation point that cannot meet the demands of the future—in electric vehicles, for example. Lithium metal batteries can provide double the energy per unit weight when compared to lithium-ion batteries. —Rajendran et al. Image: Turchanin et al.

Nano-vault architecture alleviates stress in Si-based anodes for Li-ion batteries

Green Car Congress

New research conducted by the Okinawa Institute of Science and Technology Graduate University (OIST) has identified a specific building block that improves the anode in lithium-ion batteries. Traditionally, graphite is used for the anode of a lithium-ion battery, but this carbon material has major limitations.

U Tokyo team proposes new high-capacity rechargeable battery system based on oxide-peroxide redox reaction

Green Car Congress

are proposing a new sealed rechargeable battery system operating on a redox reaction between an oxide (O 2- ) and a peroxide (O 2 2- ) in the cathode. V)—about on par with Li-sulfur’s very high theoretical energy density of ~2,600 Wh kg -1 (based on lithium-sulfur redox couple, e.g., earlier post ). and Li 2 O 2 (or O 2 2? ).

Pellion Technologies leveraging high throughput computational materials design to make progress on Mg-ion rechargeable batteries

Green Car Congress

Last week’s 4 th Symposium on Energy Storage: Beyond Lithium-ion , hosted by the Pacific Northwest National Laboratory (PNNL), brought together researchers tackling the “Beyond Li-ion” problem by working on a number of different platforms (e.g., Mg 2+ rather than Li + ). Earlier post.).
