本发明涉及种过渡金属碳纳米复合材料的制备方法，属于电极材料制备领域。该方法以杏核壳为碳源，炭化后经植物透明质酸银耳多糖改性，原位沉积镍元素，煅烧后制得过渡金属碳纳米复合材料。本发明将杏核壳用季铵盐溶液浸泡增大孔隙率，炭化后再经富含活性羟基和羧基的银耳多糖生物改性，增加碳基表面的活性沉积位点，经原位沉积法包覆层镍离子，煅烧后在碳基表面形成氧化镍层，制得多孔氧化镍碳基复合材料，即具有金属氧化物高电容量的特点，又兼备碳材料的高导电率、性质稳定的特点，是种性能优异的电极材料。 The invention relates to a preparation method for transition metal carbon nano composite materials, and belongs to the field of electrode material preparation. The method comprises the following steps: almond core shell is used as a carbon source, then carbonized and further modified by plant hyaluronic acid tremella polysaccharide and further subjected to nickel element in-situ deposition and calcination to prepare transition metal carbon nano composite materials. According to the invention, the almond core shell is soaked with a quaternary ammonium salt solution to increase the porosity, and after carbonization, the almond core shell is biologically modified by tremella fuciformis rich in active hydroxyl groups and carboxyl groups to increase active deposition sites on the c
