2023126 · In addition, the Li salt in the electrolyte is usually recovered in trace quantity. Therefore, separation of electrolytes from spent LIBs has more environmental benefits over economic benefits. In fact, electrolyte as well as other less valuable parts of the LIBs (casing, wiring, and circuits) are being recycled only to meet the new regulation ...

202321 · Section snippets Experimental section. The spent LiFePO 4 batteries were obtained from a waste disposal factory in Hunan province, China. A schematic diagram of the disposal of spent LiFePO 4 batteries is shown in Fig. 1a. The spent batteries were first crushed in a crusher without discharging (the O 2 content in crushing chamber stabilize at …

202451 · Except aspartic acid, each chelated functional organic acid can leach over 90% of Li and Co for spent LCO recovery. Oxalic acid [138] and carrot acid [139], which provide precipitation functions, can be recovered by a mechanism that uses organic groups to leach valuable metals to produce precipitates. The leaching properties follow the order …

202081 · The spent LIBs, without undergoing discharging, were crushed using the crusher designed in-house for recycling spent LIBs. Its schematic diagram is shown in Fig. 3. In each test, 5 m 3 /h of drying N 2 (purity of 99.99%) was led into the transition and crushing chambers prior to the crushing experiments to reject O 2 or H 2 O from the crusher ...

2019121 · If spent power batteries are not recycled, then they will not only cause serious environmental problems but also waste heavy metal resources. A shortage of Li material is expected when electric vehicles become extensively used, and new battery technology is required (Vikström et al., 2013). Minimum recycling rates of 25% by …
