Abstract: A method for preparing a carbon-coated ternary positive electrode material has steps of preparing a ternary positive electrode material precursor, and preparing a suspension of the ternary positive electrode material precursor. Lithium acrylate is added to the suspension of the ternary positive electrode material precursor according to the molar ratio of Li:(Ni+Co+Mn) being 1.03-1.05:1. Ammonium persulphate is added to the lithium acrylate-containing suspension of the ternary positive electrode material precursor, so that the lithium acrylate undergoes a polymerisation reaction and a suspension of a lithium polyacrylate-coated ternary positive electrode material precursor is obtained. The suspension of the lithium polyacrylate-coated ternary positive electrode material precursor is dried to obtain spherical particles. The lithium polyacrylate-coated ternary positive electrode material precursor particles are sintered to obtain a carbon-coated ternary positive electrode material.

Abstract: The portable meshi nebulizer may be assembled from and dis-assembled into a number of functional members including a reservoir member, a spray member, and a vibration member. A variety of these functional members therefore may be put together to achieve different treatment effects, depending on user requirement and the liquid medication to be applied. The present invention therefore not only is cost effective, but also is significantly convenient both in terms of storage and transportation.

Abstract: The eye nebulizer deploys at least a block piece along a tube for the nebulized medication so as to achieve an S-shaped flow path, thereby preventing the nebulized medication from directly impacting and injuring the eye. In addition, due to the altered and curved flow path, the nebulized medication would diffuse around the rim of the eye cup, thereby covering a wider treatment area around the eye. The eye nebulizer therefore achieves an enhanced treatment effect and a greater applicability.
