A supercapacity lithium ion battery cathode material, a preparation method therefor and an application thereof. The supercapacity lithium ion battery cathode material consists of a transition metal-containing lithium ion cathode material and carbon which is coated on the surface of the lithium ion cathode material. The transition metal on the surface of the lithium ion cathode material is coordinated with carbon by means of X&#x2014;C bonds to form transition metal-X&#x2014;C chemical bonds, such that carbon stably coats the surface of the cathode material, wherein C is SP3 hybridization and/or SP2 hybridization, and X is at least one selected from among N, O and S. The supercapacity lithium ion battery cathode material connects the lithium ion cathode material and the carbon by means of the transition metal-X&#x2014;C chemical bonds, and utilizes the transition metal-X&#x2014;C chemical bonds to repair boundary of lattices on the surface of the cathode material, such that an interface between the lithium ion cathode material and a carbon layer can be optimized, to form an interface that can store Li, thereby increasing the per gram capacity of the cathode material, and laying the foundation for preparing a supercapacity lithium ion battery.

Camera gimbal

A land grid array (LGA) socket apparatus includes an LGA socket, with two guide rails provided respectively on the inner sides of two opposite side walls of the socket. The height of the top surface of each guide rail from the socket's bottom is greater than the height of socket terminals from the socket's bottom. The length of each guide rail is smaller than the length of the sidewall's inner side. The guide rails support at least two protrusions provided at corners at opposite sides of an integrated circuit chip assembly when the assembly is slid into the socket from a side. The guide rails, when the assembly is slid to the end of the guide rail, enable the at least two protrusions to fall into the gaps between the ends of the guide rail and the respective socket end walls to install the assembly in the socket.
