Recovery of Cobalt from Secondary Resources: A Comprehensive Review

Michael Chandra et al.

Summary: The demand for cobalt has seen significant growth in recent years due to its wide utilization in various critical industries. Concerns arise as over half of the world's cobalt demand is supplied by just one country, raising potential risks for future supply. Recycling cobalt from secondary resources is viewed as a solution to address this issue, though it comes with its challenges.

High-voltage and long-lasting aqueous chlorine-ion battery by virtue of water-in-salt'' electrolyte

Tong Li et al.

Summary: A Chloride-ion battery (CIB) with a water-in-salt electrolyte, zinc anode, and carbon cathode demonstrated high cycling stability and initial reversible specific capacities. The carbon cathode, especially when using graphene, showed promising results with a high reversible discharge capacity even after 2000 cycles. The use of water-in-salt electrolytes also improved the discharge platform of aqueous CIBs.
