However, on the delithiated Ni-rich cathode surface, the strong catalytic effects of transition metals with coordination deficiency significantly aggravate the parasitic reactions with Li-metal-compatible ether-based electrolytes, thereby reducing the cycling stability of high-voltage Ni-rich batteries. Here, we propose an -induction mechanism to address coordination deficiency through the coupling of interfacial orbitals between molecules and the cathode surface.

NaMnTi(PO) is a promising sodium-ion cathode material due to its relatively high specific capacity, excellent thermodynamic stability and low cost. However, unfavorable electron conductivity and slow kinetics limit its practical application. Here, a strategy of hetero and multivalent anion substitution is proposed to achieve high-rate performance and good capacity retention.
