DOE: cobalt is the most expensive material used in lithium-ion battery cathodes

Green Car Congress

With the accelerating transition to electric vehicles (EVs), demand for the materials used to produce batteries will increase significantly and rapidly. Aside from the lithium needed to produce modern lithium-ion batteries, much attention is focused on the cost of the materials used for EV battery cathode production.

Lithium-ion battery recycler ABTC expands operations and capacity with newly purchased facility

Green Car Congress

The demand for domestically produced and sustainably sourced battery metals has grown at a near insatiable rate over recent years, as the domestic manufacturing capacity of lithium-ion batteries has grown exponentially from less than 50 GWh/year to now more than 700 GWh/year of operational and announced capacity.

Novel copolymer binder extends the life of lithium-ion batteries

Green Car Congress

One of the major causes for the drop in capacity over time in Li-ion batteries is the degradation of the widely used graphite anodes. interactions between the bis-imino-acenaphthenequinone groups and graphite, and also from the good adherence of the copolymer’s ligands to the copper current collector of the battery. 0c02742.

Researchers develop soft co-crystalline solid electrolyte for lithium-ion batteries

Green Car Congress

A substantially high ion conductivity (~10 −4  S cm –1 ) and lithium-ion transference number (0.54) are obtained due to weak interactions between ‘hard’ (charge dense) Li + ions and the ‘soft’ (electronically polarizable) –C≡N group of Adpn. 2023) “A soft co-crystalline solid electrolyte for lithium-ion batteries.”

Benchmark: lithium-ion battery prices rise for first time in gigafactory era; lithium carbonate major driver

Green Car Congress

Benchmark Mineral Intelligence reports that battery producers have begun to increase lithium-ion cell prices following a period of consistent raw material price rises throughout 2021, particularly for lithium. Lithium carbonate has been singled out as a major driver behind the battery cell price increases.

MIT, Brookhaven team develops simple method for stabilizing interfaces in solid-state lithium-ion batteries

Green Car Congress

Solid-state batteries could potentially not only deliver twice as much energy for their size, they also could virtually eliminate the fire hazard associated with today’s lithium-ion batteries. The findings are reported in an open-access paper in the journal Advanced Energy Materials.
