New class of high entropy materials for energy storage applications

Green Car Congress

A team led by researchers from the Karlsruhe Institute of Technology (KIT) in Germany is proposing a new class of high entropy materials for energy storage applications. The Li-containing entropy-stabilized oxyfluoride (Li x (Co 0.2 V vs. Li + /Li, enabling its use as a cathode active material.

Navy researchers boost performance of Ni-Zn cells commensurate with Li-ion; safer alternative

Green Car Congress

With 3-D Zn, the battery provides an energy content and rechargeability that rival lithium-ion batteries while avoiding the safety issues that continue to plague lithium. B) The calculated specific energy of a fully packaged Ni–Zn cell as a function of increasing Zn depth of discharge versus a capacity-matched NiOOH electrode. (B)

New cobalt-free high-voltage spinel cathode material with high areal capacity

Green Car Congress

Advancing cathode materials with both high energy density and low cost have always been the main objective of battery material research. It should be noted, the cost and sustainability of lithium-ion batteries are not only limited by the production of Co and Ni but also potentially limited by the lithium element itself. …

New strategy for dendrite-free Li-metal batteries based on atomic channels

Green Car Congress

An open-access paper on the work is published in the RSC journal Energy & Environmental Science. Since the surface diffusion of Li in anode is much faster than bulk diffusion, tuning diffusion/deposition of Li on anode surface has been regarded as a mainstream method to induce its uniform deposition. atomic channels.

Roskill forecasts Li-ion battery demand to increase more than ten-fold by 2029 to >1,800GWh

Green Car Congress

Roskill forecasts that Li-ion battery demand will increase more than ten-fold by 2029, reaching in excess of 1,800GWh capacity. In the late 2020s, Li-ion technologies could see increasing competition from other battery technologies, though Li-ion cells are expected to maintain their dominant position, Roskill said.
