Developing olivine-type lithium ferromanganese phosphates with high ionic/electronic conductivity is vital to promote their practical application in long-life and high-rate lithium-ion batteries (LIBs). Herein, we propose a dual modification strategy combining C-coating Nb-doping apply it enhance LiFe0.5Mn0.5PO4 cathode materials. The uniform compact layer successfully fabricates the high-speed conductive network among primary particles meantime prevents attack of electrolytes. strong Nb–O coordination can effectively accelerate ion diffusion electron transport within nanoparticles while suppressing Jahn–Teller effect Mn3+. modifications synergistically improve materials superior lithium-storage capacities 152 115 mAh g–1 at 0.1 5 C, respectively. Furthermore, exhibits an impressive cycling performance ultrahigh capacity retention 95.4% after 1000 cycles 1 C. These findings extend surface-to-bulk co-modification developing novel used high-performance LIBs.

Abstract LiMn 2 O 4 and LiFePO materials are widely applied in electric vehicles energy storage. Currently, spent recycling is challenged by long process, high consumption, poor economy due to the indispensable metal separation their recycling. Aiming at this challenge, an upcycling of low‐value cathode high‐value high‐voltage lithium ferromanganese phosphate (LMFP) simple leaching hydrothermal reaction proposed, LMFP material with ultrahigh rate capability reversibility its homogenized element distribution, well‐defined nanorods particles, short Fe/Mn─O bond average Li─O length regenerated. The initial discharge capacity reaches 144.2 mAh g −1 87% retention after 1000 cycles 1 C. Even cycling 5 C, a 136.9 86.4% achieved cycles. Kinetics analysis characterizations regenerated further reveal fast diffusion ability stable structure. This work sheds light on potential value regeneration offers economic strategy for materials.

Abstract A smooth interfacial contact between electrode and electrolyte, alleviation of dendrite formation, low internal resistance, preparation thin electrolyte (<20 µm) are the key challenging tasks in practical application Li 7 La 3 Zr 2 O 12 (LLZO)‐based solid‐state batteries (SSBs). This paper develops a unique strategy to reduce resistance by designing an interface‐based core–shell structure via direct integration Al‐LLZO ceramic nanofibers incorporated poly(vinylidene fluoride)/LiTFSI on surface porous cathode (HPEIC). yields ultrathin solid polymer with thickness µm. The integrated HPEIC/Li SSB LiFePO 4 /C exhibits initial specific capacity 166 mAh g −1 at 0.1 C 159 retention 100% after 120 cycles 0.5 (25 °C). LiNi 0.8 Mn Co delivers good discharge 134 C. rational design outperforms conventional assembly cells using free‐standing electrolytes capacity, rate performance. proposed is simple, cost‐effective, robust, scalable manufacturing, which essential for applicability SSBs.
