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.

US DOE releases 2023 Critical Materials Assessment to evaluate supply chain security for clean energy technologies

Green Car Congress

While cobalt (Co) was found to be critical in this and previous reports, lithium (Li) becomes critical in the medium term due to its broader use in various battery chemistries and the rampant growth of the EV industry. Materials used in batteries for EVs and stationary storage are now considered to be critical.

Sulfur nanodots on nickel foam as high-performance Li-S cathode materials; carbon- and binder-free

Green Car Congress

A team at Nankai University in China has devised high-performance Li-sulfur battery cathode materials consisting of sulfur nanodots (2 nm average) directly electrodeposited on flexible nickel foam; the cathode materials incorporate no carbon or binder. However, the electrochemical inertness of bulk sulfur in the cathode of Li?S

Dahn team develops ethylene-carbonate-free electrolytes for better-performing high-voltage Li-ion cells

Green Car Congress

Conventional electrolytes for Li-ion batteries contain ethylene carbonate (EC) and other additives. However, the cycling performance of Li-ion cells using these carbonate-based electrolytes has been poor at higher voltages (≥4.4 A paper on their work is published the Journal of Power Sources.

Stanford researchers develop new electrolysis system to split seawater into hydrogen and oxygen

Green Car Congress

A continuous, highly oxygen evolution reaction-active NiFe electrocatalyst layer drawing anodic currents toward water oxidation and an in situ-generated polyatomic sulfate and carbonate-rich passivating layers formed in the anode are responsible for chloride repelling and superior corrosion resistance of the salty-water-splitting anode.
