Chromium oxide/CNTS composite material and preparation and application thereof

The invention belongs to the technical field of lithium primary battery positive electrode material preparation, and particularly relates to a chromium oxide/CNTS composite material and preparation and application thereof. The chromium oxide/CNTS composite material is prepared from chromium oxide and carbon nanotubes as raw materials through a high-temperature solid-phase method or a high-energy ball milling method. The CNTS with good conductivity is compounded with the chromium oxide, so that the conductivity of the obtained composite material is obviously improved, the capacity is increased, and the rate capability is improved. 本发明属于锂原电池正极材料制备的技术领域，具体涉及一种铬氧化物/CNTS复合材料及其制备与应用，所述铬氧化物/CNTS复合材料以铬氧化物与碳纳米管为原料，采用高温固相法或高能球磨法制作而成，本发明使用导电性好的CNTS与铬氧化物进行复合，得到的复合材料导电性得到明显改善，容量升高，倍率性能提升。
