Dalhousie researchers find low-voltage NMC532 cells have higher energy density than LFP, very long lifetime

Green Car Congress

Single crystal Li[Ni 0.5 V vs Li + /Li. V vs Li + /Li, or 4.2 The team noted that in addition to superior lifetime compared to LFP cells, the use of NMC materials in cells balanced to low voltages present a multitude of opportunities for improved Li-ion batteries. Li[Ni 0.95 Aiken et al.

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. Electrical steel is near critical due to its use in transformers for the grid and electric motors in EVs.
