We conclude that CrGeTe3 crystals possess the ability to intercalate lithium ions with a high specific discharge capacity of 537.5 mAh/g. We also investigate the direct regeneration of degraded graphite anode by washing it with various organic solvents under different temperatures. We successfully revived the spent graphite from a specific capacity of 188.23 mAh/g to 224.66 mAh/g at 0.02 C rate and from 41.53 mAh/g to 157.36 mAh/g at 0.1 C rate, by washing with a solution of iodine in ethanol. Washing in anhydrous acetonitrile at 50 °C also restores the capacity of spent graphite to 226.5 mAh/g at 0.02 C rate. Washing the spent graphite in acetonitrile containing 0.5% water content at 70 °C exhibited a high restored specific capacity of 215.9 mAh/g at 0.02 C rate and 168.36 mAh/g at 0.1 C rate. These results pave way for ecofriendly full-body regeneration of lithium-ion batteries.application/pdfenLi-ion batterybattery recyclingbattery regenerationlayered materialsvan der Waals crystalseco-friendlyelectric vehiclesrechargeable batteriesThesis2025-01-16
