Manganese (Mn)-based layer-structured transition metal oxides are considered as excellent cathode materials for potassium ion batteries (KIBs) owing to their low theoretical cost and high voltage plateau. The energy density cycling lifetime, however, cannot simultaneously satisfy the basic requirements of market storage systems. One primary causes results from complex structural transformation migration during intercalation deintercalation process. orbital electronic structure octahedral center element plays an important role maintaining integrity improving K+ diffusivity by introduced heterogeneous [Me-O] chemical bonding. A multitransition oxide, P3-type K0.5Mn0.85Co0.05Fe0.05Al0.05O2 (KMCFAO), was synthesized employed a material KIBs.

Layered transition-metal (TM) oxides have drawn ever-growing interest as positive electrode materials in potassium-ion batteries (PIBs). Nevertheless, the practical implementation of these is seriously hampered by their inferior cyclic property and rate performance. Reported here a self-templating strategy to prepare homogeneous P2-K0.6CoO2 (KCO) microcubes. Benefiting from unusual microcube architecture, interface between electrolyte active material considerably diminished. As result, KCO microcubes manifest boosted electrochemical properties for potassium storage including large reversible capacity (87.2 mAh g-1 under 20 mA g-1), superior performance, ultralong steady (an improved retention 86.9% 40 after 1000 cycles).

Here, lithium difluoro(oxalate) borate (LiDFOB) is introduced as an electrolyte additive improve the electrochemical P3‐type KMO. LiDFOB creates a uniform, thin, robust cathode‐electrolyte interphase layer on cathode surface, enhancing reaction kinetics, preventing stabilizing structure. The P3‐KMO with basic exhibits significantly improved performance, such remarkable Coulombic efficiency ≈99.5% capacity retention 78.6% after 300 cycles at 100 mA g −1 .
