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

Green Car Congress

. … 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. … The price of Co fluctuates significantly, with the inconspicuous fall of Ni price and continues growing of Li price. —Li et al. (a)

HIU researchers develop extremely high energy density lithium-metal cell with good stability

Green Car Congress

Although lithium-metal batteries are attractive as a higher-capacity energy storage solution than current Li-ion batteries, their stability poses a challenge because the electrode materials react with common electrolyte systems, affecting stability. Joule doi: 10.1016/j.joule.2021.06.014. 2021.06.014.

Researchers determine cause of voltage fade in NMC cathode materials, find it is reversible

Green Car Congress

Lithium-rich layered oxides (LRLO) are leading candidates for the next-generation cathode materials for energy storage, as they can deliver 50% excess capacity over commercially used compounds. Here, we directly capture the nucleation of a dislocation network in primary nanoparticles of the high-capacity LRLO material Li 1.2

Envia Systems announcement may herald the first wave of DOE-supported commercial high energy density Li-ion cells with Si-C anodes

Green Car Congress

While Envia Systems is the first integrated cell producer to announce success with that type of combination, other providers of Si-C materials or IP—such as, but not limited to, Nanosys and the DOE’s own Argonne National Laboratory, respectively—are also currently deep in the process of development and/or commercialization.

Researchers call for integration of materials sustainability into battery research; the need for in situ monitoring

Green Car Congress

We need new storage technologies if more renewables are to be used on the electrical grid; similarly, the electrification of transport requires much cheaper and longer-lasting batteries. The size of these batteries (in comparison to those used for portable electronics) places severe pressure on materials resources. Elemental resources.
