Abstract: Disclosed are an array substrate, a display panel and a display apparatus. The array substrate includes: gate lines, data lines, and pixel units. The gate lines and the data lines are arranged between at least part of the adjacent pixel units. The array substrate further includes: common electrode lead wires and common electrode layers. The common electrode lead wires are arranged on a same layer as the data lines, extend in a same direction as the data lines, and are located between at least part of the adjacent pixel units. The common electrode layers are insulated from the common electrode lead wires through insulating layers and are connected with the common electrode lead wires through via holes in the insulating layers. The via holes are located in a region where the gate lines and the common electrode lead wires intersect.

Abstract: A lithium ion battery includes a cell assembly, a casing containing the cell assembly with electrolyte filling therein, a cap assembly a retaining member and an insulator. The cell assembly comprises a number of stacked electrode plates, each electrode plate having an electrode ear. The cap assembly includes a cap plate covering a top side of the casing, a pair of electrode terminals assembled to one side face of the cap plate, and a pair of cap ears connecting to and electrically separated from the other side face of the cap plate. The retaining member is connecting the cap plate, the pair of electrode terminals and the cap ears, and the insulator electrically separates the electrode terminals with the cap plate and the cap ears.

Abstract: A battery module includes a top bracket, a bottom bracket, a number of batteries clamped by the top and bottom brackets, and an insulative cover fixed to a top side of the top bracket. The top bracket includes a number of top recesses and a number of top separators separating the top recesses from each other. The bottom bracket includes a number of bottom recesses and a number of bottom separators separating the bottom recesses from each other. The top recesses and the bottom recesses are aligned with each other for fixing top sides and bottom sides of the batteries, respectively. The batteries are separated from each other by the top separators and the bottom separators.

Abstract: A battery system includes a battery module, a frame for receiving the battery module, a cover covering the frame, a heat sink, a battery management circuit board and a battery balancing circuit board. The battery module includes a bracket assembly and a number of batteries fixed to the bracket assembly. The batteries are electrically connected to each other. The battery management circuit board is fixed to the bracket assembly and electrically connected to the batteries. The battery management circuit board is separated by a distance from the bracket assembly. The battery balancing circuit board is fixed to the heat sink and includes a battery balancing control module for controlling surplus electric energy of the batteries dissipated into thermal energy.

Abstract: A lithium ion battery includes a cell assembly, a casing containing the cell assembly, a cap assembly and electrolyte filling in the casing. The cell assembly has stacked electrode plates with separators disposed between neighbored electrode plates. The casing has a bottom wall, a number of side walls extending vertically from the bottom wall, and a receiving space defined by the bottom wall and the number of side walls with an opening opened outwards. The cap assembly includes a cap plate covering the opening and encapsulating the cell assembly in the casing. A recessed structure is formed on the side wall of the casing.
