Abstract: A positive electrode material has a chemical general formula of LiaNixCoyMnzO2·cA·dB, in which 1.00?a?1.20, 0.00<c?0.01, 0.00<d?0.02, 0.00?x<1.00, 0.00?y<0.2, 0.00?z<0.4, and x+y+z=1; A is a first coating material, and B is a second coating material; and the first coating material A is a carbon-coated fast-ionic conductor, and the second coating material B is a carbon escape-prevention compound. A fast-ionic conductor modified through carbon coating is used to modify a positive electrode material, such that the ionic conductivity and the electronic conductivity of the positive electrode material are synchronously improved. The surface of the carbon-coated fast-ionic conductor is coated with boric acid due to the glassy property, such that the escape of carbon in the carbon-coated fast-ionic conductor is effectively prevented.

Abstract: The invention discloses a tunnel boring machine (TBM) equipped with a high-pressure water jet cutting system and a combined tunneling method, comprising a TBM body, the water pump unit on the body, and the high-pressure water jet cutting system at the front end of the body. The high-pressure water jet cutting system comprises a water jet-mechanical combined cutter head, water jet-shell knife combined cutters, a high-pressure water pipeline, a multi-medium rotary center, and a water jet diversion valve block. The high-pressure water at the pump unit is transmitted to the multi-medium rotary center through the high-pressure water conveying pipeline, and then divided into multiple paths by the water jet diverter valve block, and respectively supplied to each of the combined cutters on the water jet-mechanical combined cutter head. This invention offers practical suggestions and references for the overall design, and spatial arrangement of the high-pressure water jet cutting system.
