In-situ growth carbon oxide composite negative electrode and solid-state battery preparation method

The invention discloses an in-situ growth carbon oxide composite negative electrode and a solid-state battery preparation method. Graphite and carbon nanotube slurry are compounded with a proper amount of oxide according to a certain proportion, then the mixture is uniformly stirred with a proper amount of organic matter, and a conductive substrate is coated with the mixture; the in-situ growth 3Dreticular porous carbon coated oxide negative electrode is obtained through carbonization at high temperature, the in-situ growth electrode is used as the negative electrode to be manufactured into asolid-state battery, the negative electrode has the characteristics of high specific capacity, high conductivity and long service life, and the prepared solid-state battery has high power density andlong service life. And the method is suitable for solid-state battery performance with certain requirements on energy density and power density. 本发明公开了一种原位生长碳氧化物复合负极及固态电池制备方法，通过将石墨和碳纳米管浆料按照一定比例和适量的氧化物复合，再与适量有机物搅拌均匀，涂覆到导电基材上，在高
