Discharge treatment is a vital process in the pretreatment of spent lithium-ion batteries (LIBs). This paper focuses on effects ultrasonic discharge LIBs from perspective electrolyte concentration and power. By integrating characterizations such as pH measurement X-ray fluorescence (XRF), effect evaluated. Experimental results show that sodium chloride (NaCl) solution potassium (KCl) have more significant better efficiency (DE) under treatment, while organic solutions which mainly contain formate acetate generally less ideal DE. Under experimental conditions using with various concentrations same power 300 W, DE generated condition KCl 30 g/200 mL deionized water highest, 64.9%; different powers solutions, 10 wt.% HCOONa highest at 500 4.7%. work provides reference for efficient cost-effective mechanism also explored to support recycling LIBs.

Abstract The loss of active lithium during the initial charge process significantly reduces both energy density and cycle life lithium‐ion batteries. Cathode replenishment is a promising alternative to metal‐based prelithiation; however, development efficient cathode agents remains limited. Organic offer advantages over inorganic counterparts, including superior air stability, abundant resources, minimal solid residue after oxidation, providing high specific capacity comparable metal degassing. Nevertheless, there need for diverse effective organic agents. Herein, ketomalonate‐based agents: dilithium ketomalonate (DLMT) tetralithium (TLMT) with uniform spherical particles ≈1 µm are developed. Both DLMT TLMT demonstrate capacities excellent compatibility standard battery manufacturing processes. Their complete decomposition, coupled uniformly distributed pores, preserves structural integrity ensures stable electrochemical performance. Incorporating these into cathodes led 20.5% improvement in retention 500 cycles LFP||Gr full cells increased by 5.7% 7.2% LMFP||Gr cells. design novel sacrificial salts, emphasizing stability efficiency, underscores their potential high‐performance
