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

Green Car Congress

An international team of researchers has developed a new strategy for dendrite-free lithium-metal batteries based on the use of interlayer and intralayer atomic channels in graphite formed by pre-tunnelling the graphite layers. An open-access paper on the work is published in the RSC journal Energy & Environmental Science.

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. …

Study finds resource constraints should not be a limiting factor for large-scale EV battery production

Green Car Congress

(A) Energy storage potential (ESP) based on annual production of the elements. On the order of 1 billion 40 kWh Li-based EV batteries could be built with the currently estimated reserve base of lithium, according to a recent study by researchers from Lawrence Berkeley National laboratory and the University of California, Berkeley.

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

Green Car Congress

Joseph Parker, Jeffrey Long, and Debra Rolison from NRL’s Advanced Electrochemical Materials group are leading the effort to create an entire family of safer, water-based, zinc batteries. The long-standing limitation that has prevented implementing Zn in next-generation batteries lies in its poor rechargeability due to dendrite formation. (A)
