A team from metals research institute SWERIM in Sweden reports on a smelting reduction process to recover cobalt, nickel, manganese and lithium simultaneously from spent Li-ion batteries. The presence of slag may retain some Co, Ni, Mn, and Li in the slag due to the inherent nature of the slag. —Hu et al. —Hu et al.

Charge–discharge profiles of ion-exchanged MgFeSiO 4. Three-electrode cells using Mg metal counter electrode and silver reference electrode were used. A team of researchers from Kyoto University has demonstrated ion-exchanged MgFeSiO 4 as a feasible cathode material for use in high-energy-density rechargeable magnesium batteries.

Iron–air batteries, originally proposed in the 1970s, have theoretical energy densities of more than 1,200 Wh/kg; by comparison, present-day lithium-ion batteries come in at about 600 Wh/kg, and even less (350 Wh/kg) if the weight of the cell casing is taken into account. —Weinrich et al.

The lithium-ion battery has proven to be an excellent fuel tank for EVs, but there remains much room for improvement. We’re still far from what’s theoretically achievable in terms of Li-ion capacity, safety, cost and charge times. While nickel isn’t [as expensive as] cobalt, nickel isn’t as cheap as some others.
