摘要 |
The invention relates to chemical technology and is used for producing cathode materials having a NASICON structure for lithium autonomous energy systems (hybrid transportation, electric vehicles, energy storage buffer systems etc.). The method involves mixing a lithium salt (Li2CO3), vanadium oxide (V2O5), and ammonium dihydrogen phosphate (NH4H2PO4) in a stoichiometric ratio and using starch (C6H10O5)n as a reducing agent and a carbon component precursor. The particles of the mixture are ground in a ball mill in an acetone medium, and subsequently thermally treated at a temperature of 750-850ºC. The invention allows for producing a composite material having high indicators of specific capacitance and power and also having an acceptable cycling stability. |
