Abstract: Embodiments include membrane restoration process. A membrane can be restored by replacing an anolyte and a catholyte of a cell with a solution having an organic acid. The cell can include an anode, a cathode and a membrane fouled with a metal. A cheleate can be formed with the metal and the organic acid of the solution and an electric current can be provided between the anode and the cathode of the cell to protect the cell from corrosion while forming the chelate.

Abstract: A structure of lithium-ion battery module comprises a battery case, containing one or more flexible packaging polymer lithium-ion battery cells, at of which top a connecting conductor is arranged to connect them in series and/or parallel to form a battery pack, positive and negative poles of the battery pack are mounted on the connecting conductor. The structure further comprises a battery cover plate welded on the open end of the battery case to package the battery pack into the battery case, and the positive and negative pole terminals of the battery module are arranged on the battery cover plate and welded to the positive and negative poles. The plate is provided with one or more through hole, through which the air in the battery case is evacuated and the inert gas is injected, after that a steel ball is clamped into each through hole to seal the battery case.

Abstract: A computer enclosure includes a chassis (40) and a holder bracket (10). A plurality of guideways (48) is defined in the chassis. A rear wall (46) of the chassis includes an opening (51), a plurality of screw holes (59), and a plurality of claws (57). The curvature of each claw is adjustable thereby adjusting engagement between the claw and a slot cover of an expansion card. The holder bracket includes a base (12) and a panel (14) extending perpendicularly from the base. The base forms a plurality of hooks (16) for engaging with the guideways of the chassis. The panel is accommodated at the opening of the chassis. A plurality of through holes (25) is defined in the panel for extension of screws (60) therethrough into the screw holes, to secure the holder bracket to the chassis.
