Abstract Owing to its abundant manganese source, high operating voltage, and good ionic diffusivity attributed 3D Li‐ion diffusion channels. Spinel LiMn 2 O 4 is considered a promising low‐cost positive electrode material in the context of reducing scarce elements such as cobalt nickel from advanced lithium‐ion batteries. However, rapid capacity degradation inadequate rate capabilities induced by Jahn–Teller distortion dissolution have limited large‐scale adoption spinel for decades. In this study, 1.98 Mg 0.005 Ti Sb Ce (HE‐LMO) with remarkable interfacial structural cycling stability developed based on complex concentrated doping strategy.

Highly selective and efficient extraction of lithium from brine is considered a promising strategy to alleviate the imbalance between supply demand resources. However, it still challenging for ions (Li+) recovery brine. In this work, LiMn2O4 nanoparticles embedded in situ carbon networks (LMO-C) derived metal–organic frameworks by incomplete calcination have been developed via hybrid capacitive deionization (HCDI) process.
