  • Anode active material and anode for lithium-ion battery, method for preparing the anode active material, and lithium-ion battery
    Patent number: 10978695
    Abstract: An anode active material for a lithium-ion battery with greatly reduced recharging time includes SiO particles, graphite particles, and a carbon coating layer. The graphite particles and SiO particles are processed to form spherical SiO/graphite composite particles. A layer of carbon coating is applied to the surface of the SiO/graphite composite particle and the resulting anode active material resembles a pomegranate structure.
    Type: Grant

  • AUTOMATIC POLISHING DEVICE FOR SURFACE FINISHING OF COMPLEX-CURVED-PROFILE PARTS
    Publication number: 20130273816
    Abstract: The present invention discloses an automatic polishing device and the method of using the device for the surface finishing of a workpiece such as complex-curved-profile parts. Automatic polishing is performed by mounting the workpiece on an apparatus which enables different orientations along multiple axes and immerging the workpiece in a controlled flow of abrasive slurry. The device of the present invention provides a uniform finish on free form surface. It is also precise, low cost, non-destructive, and non-polluting.
