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.

China dominates BloombergNEF’s (BNEF) lithium-ion battery supply chain ranking in 2020, having quickly surpassed Japan and Korea that were leaders for the majority of the previous decade. China’s dominance of the industry is to be expected given its huge investments and the policies the country has implemented over the past decade.

A team of researchers at MIT and Tsinghua University has developed a high-rate, high-capacity and long-lived anode for Li-ion batteries comprising a yolk-shell nanocomposite of aluminum core (30 nm in diameter) and TiO 2 shell (~3 nm in thickness), with a tunable interspace (Al@TiO 2 , or ATO). —Li et al.

However, chemical vapour deposition (CVD) using highly toxic, expensive, and pyrophoric silane requires costly setups and cannot produce anode material on the industry level. The MgCl 2 produced via HCl etching of MgO can be recycled back to Mg via electrolysis—the predominant industrial synthesis route for Mg production.

The situation is the same for the battery packs, which actually take up the most space in boxy designs unconventional for the moto industry (even when utilizing high-energy automotive-grade Li-ion cells). In contrast, low energy, cheap LFP packs sourced from China can be used for the low energy needs of electric scooters.

The majority of the projects are targeted at making copper foil for lithium-ion batteries to meet demand from EVs. Copper foil is the most commonly used anode current collector in Li-ion batteries; it not only lets electric current flow but also dissipates the heat generated by the battery.
