  • Three-dimensional nanosized porous metal oxide electrode material of lithium ion battery and preparation method thereof
    Patent number: 9985273
    Abstract: A preparation method of a three-dimensional nanosized porous metal oxide electrode material of lithium ion battery, which soaks a dried polymer colloidal crystal microsphere template in a metal salt solution as a precursor solution for a period of time, and obtains a precursor template complex after filtration and drying; heats the precursor template complex to a certain temperature at a low heating rate and keeps the temperature, and then obtains the three-dimensional nanosized porous metal oxide electrode material of lithium ion battery after cooling to room temperature. A metal oxide electrode material is manufactured, with the three-dimensional nanosized porous metal oxide electrode material thereby improving the ionic conductivity of the negative electrode material of lithium ion battery, and shortens the diffusion path of the lithium ions during an electrochemical reaction process, and improves the rate discharge performance of lithium ion battery greatly.
