TL;DR: In this paper, a hard carbon sheet-like structure has been successfully prepared with a short flow process by simply using cherry petals (CPs) as the raw materials, which can provide a high initial reversible capacity of 310.2 mA h g−1 with a favorable initial Coulomb efficiency of 67.3%.

TL;DR: Using glucose as reductant to dissolve LiCoO2 with chelating agent of phosphoric acid is achieved here and Co in solution was recovered as Co-oxalate after leaching process.

TL;DR: A hard carbon material with a "honeycomb" structure using pine pollen as a precursor was successfully prepared and applied as an anode, and Carbonized PP exhibited excellent electrochemical properties because of its three-dimensional structure and larger layer spacing.

TL;DR: In this paper, Toluenesulfonyl isocyanate (PTSI) is introduced as electrolyte additive in a bid to enhance the electrochemical performances of LiNi0.5Co0.3O2 cathode materials under high voltage.

TL;DR: In this paper, the authors focused on the use of electrochemical cathode-reduction method for leaching LiCoO2 produced by spent lithium-ion batteries, and the thermodynamics, kinetics, and electrochemical impedance spectroscopy analyses were used to determine the probable control mechanism involved in the leaching of cobalt from spent LiCOO2.
