Exogenous pillaring engineering toward stable layered potassium manganese oxide cathodes

Layered potassium manganese oxides (KMO) offer a theoretically high energy density but intrinsically suffer from insufficient structural stability driven by Jahn–Teller lattice distortion. Herein, we report a spatially distributed pillaring structure that enables synergistic bulk...

Reconciling strong coordination and anion-reinforced solvation structure enables nonflammable electrolytes for potassium-ion batteries

Nonflammable electrolytes are pivotal for improving the safety of potassium-ion batteries. However, their broad adoption has been hindered by the inadequate electrode compatibility of conventional nonflammable electrolytes, which typically result from strong solvation and excessi...
