Yun-Feng Meng et al.

Summary: The increasing popularity of new energy electric vehicles has led to a rapid growth in the demand for lithium-ion batteries (LIBs), resulting in a large number of spent LIBs. This study proposes a unique recycling strategy to achieve the concurrent reuse of cathode and anode in spent graphite/LiFePO4 batteries, leading to the development of a sustainable and economical method for designing new-type secondary batteries as recycling of spent LIBs. The recycle-derived DIB of Li/RLFPG exhibits good electrochemical performance, demonstrating the potential of large-scale recycling of spent LIBs in the future.

A new bioleaching strategy for the selective recovery of aluminum from multi-layer beverage cans

Klemens Kremser et al.

Summary: This study explored the use of three bioleaching bacteria to selectively leach aluminum from the epoxy layer, with leaching efficiencies reaching around 92% after three weeks of incubation. Surface characterization showed that the nature of the epoxy resin remained unchanged after bioleaching application, allowing for recycling. Selective precipitation of dissolved aluminum from lixiviants at pH = 6.5 resulted in aluminum hydroxide precipitation efficiencies of almost 100%, demonstrating the significant potential of acidophilic bacteria in the separation and recycling of multi-layer materials.
