Abstract Adding extra raw materials for direct recycling or upcycling is prospective battery recycling, but overlooks subtracting specific components beforehand can facilitate the to a self-sufficient mode of sustainable production. Here, subtractive transformation strategy degraded LiNi 0.5 Co 0.2 Mn 0.3 O 2 and LiMn 4 5 V-class disordered spinel 1.5 -like cathode material proposed. Equal amounts Ni from are selectively extracted, remaining transition metals directly converted into 0.4 0.1 (CO 3 ) precursor preparing with in-situ doping. The improved conductivity bond strength delivers high-rate (10 C 20 C) high-temperature (60 °C) cycling stability. This no input be generalized practical black mass reduces dependence current production on rare elements, showing potential spent next-generation Li-ion industry.

Abstract In situ polymerization to prepare quasi‐solid electrolyte has attracted wide attentions for its advantage in achieving intimate electrode–electrolyte contact and the high process compatibility with current liquid batteries; however, gases can be generated during remained final electrolyte, severely impairing uniformity electrochemical performance. this work, an polymerized poly(vinylene carbonate)‐based high‐voltage sodium metal batteries (SMBs) is demonstrated, which contains a novel multifunctional additive N ‐methyl‐ ‐(trimethylsilyl)trifluoroacetamide (MSTFA). MSTFA as high‐efficient plasticizer diminishes residual after polymerization; softer homogeneous enables much faster ionic conduction. The HF/H 2 O scavenge effect of mitigates corrosion free acid cathode interfacial passivating layers, enhancing cycle stability under voltage. As result, 4.4 V Na||Na 3 (PO 4 ) F cell employing optimized possesses initial discharge capacity 112.0 mAh g −1 retention 91.3% 100 cycles at 0.5C, obviously better than those counterparts without addition. This work gives pioneering study on gas residue phenomenon electrolytes, introduces silane that effectively enhances performance SMBs, showing practical application significance.

Spinel‐structured LiNi 0.5 Mn 1.5 O 4 cathodes in lithium‐ion batteries have gained attention for their high operating voltage, which provides energy density, and cost advantages due to the absence of cobalt. However, issues such as low cycle thermal stabilities been identified, with side reactions occurring at electrode/electrolyte interface during continuous charge/discharge cycles that degrade electrode performance.
