Polyanionic cathode materials are increasingly used in research because of their good cycling performance, high theoretical capacity, and high operating voltage. However, it exhibits poor performance due to its structure, which prevents it from reaching its full theoretical capacity. In this study, carbon‐coated Li6V3(PO4)5@C cathode materials are constructed under Li3V2(PO4)3 research conditions using the sol–gel process and anhydrous citric acid as the carbon source. Several boron doping concentrations are investigated to create Li6V3(PO4)5@BC cathode materials. The electrochemical measurements demonstrate that during the first cycle, at a current density of 0.5 C and a B doping quantity of 2 wt%, the specific discharge capacity of Li6V3(PO4)5@BC reaches 167.43 mAh g−1. The steady discharge specific capacity following 80 cycles of constant‐current charging and discharging is 136.84 mAh g−1. Li6V3(PO4)5@BC‐2 has a specific discharge capacity of 131.1 mAh g−1 at 2 C. The material's electrochemical performance greatly improves following the right quantity of B doping, which is primarily attributed to the increase in carbon layer defects brought on by B's entrance. This can increase the rate of lithium‐ion migration and hold more lithium ions.

“…[11][12][13][14] Currently used inorganic fillers include inert fillers with lower ionic conductivity and active fillers with higher ionic conductivity, also known as fast ion conductors. 15 Li 7 La 3 Zr 2 O 12 , 16 LiAlO 2 , 17 Li 1.5 Ge 2 (PO 4 ) 3 , 18 Li 3 N, 19 Al 2 O 3 , 20 TiO 2 , 21 ZrO 2 , 22 SiO 2 , 23 ferroelectric material, 24,25 etc., can properly improve the ionic conductivity and material stability. However, whether active or inert fillers are added to the polymer in the form of randomly distributed nanoparticles, the agglomeration of fillers will be caused by the excessive addition of fillers, which leads to long migration paths and high transport resistance of lithium ion in electrolyte.…”

Summary Polymer solid electrolyte with high ionic conductivity at room‐temperature is most likely to be widely used in solid‐state lithium batteries. In this work, the novel surface lithiated TiO2 nanorods were firstly used as ionic conductor in polymer solid electrolyte. The surface lithiated TiO2 nanorods‐filled polypropylene carbonate polymer composite solid electrolyte (CSE) has an uniform composite structure with a thickness of about 60 μm. The ionic conductivity at room‐temperature is 1.21 × 10−4 S cm−1 and the electrochemical stability window is up to 4.6 V (vs Li+/Li). The assembled NCM622/CSE/Li solid‐state battery shows a stable cycle performance with a retention capacity of 120 mAh g−1 after 200 cycles at the current density of 0.3 C and a high coulomb efficiency of 99%. Compared with TiO2 particles, this novel surface lithiated TiO2 nanorods can provide more continuous ion transport channels and more Lewis acid‐base reactive sites, provide a novel way to enhance the lithium ion transport in polymer solid electrolyte.
