Controllable preparation of phosphonium-based polymeric ionic liquids as highly selective nanocatalysts for the chemical conversion of CO2 with epoxides

A novel approach to overcoming the insulating properties of olivine 5 V electrode materials is realized in carbon-free LiCoPO4 thin films by tailoring its chemical composition via the incorporation of lithium cobalt triphosphate into the olivine phase, thereby forming a network of conductive channels. The cyclic voltammograms of the engineered material exhibited a redox potential of ≈4.8 V/4.9 V. The experimentally obtained energy diagram quantified the inductive effect which led to the increase of the redox energy by ≈1.0 eV in comparison to LiCoO2 layered oxide. Although the enhanced electronic conductivity and excellent electrochemical activity were obtained by using the thin film cathode material, the strategy of the design of olivine with triphosphate can be extended to more thick electrodes (>1 μm), giving a perspective for the development of 5 V all solid state batteries suitable for commercial application. The evident ability to exchange the charge of all Co2+ ions with lithiation/delithiation reaction and deliver high power in carbon free high voltage cathode material opens up new perspectives for the development of next generation of high energy density electrochemical storage devices.
