Abstract: A nonaqueous electrolyte composition for use in a redox flow battery system, comprising a nonaqueous supporting electrolyte and a ligand metal complex as an electrochemically active component.

Abstract: A portable work and storage container includes a container frame, an enclosure arrangement and a wall panel affixing arrangement. The container frame includes a ceiling frame, a floor frame and four vertical corner posts spacedly extended between the ceiling frame and the floor frame. The wall panel affixing arrangement includes a plurality of wall adjusters and a plurality of wall lockers, wherein every two of the wall adjusters are adjustably extended to bias against two outer side rims of the wall structure respectively for applying a pushing force so as to ensure the wall panels of each of the wall structure are coupled with each other side-by-side. The wall lockers are adjustably engaged with top rims of the wall structures respectively to lock up the wall structures between the ceiling frame and the floor frame so as to securely retain the wall.

Abstract: A joint structure for portable work and storage container includes a plurality of joint members and a plurality of reinforcing shafts. Each joint member includes an upper joint extended from a top retention frame, a lower joint extended from a bottom retention frame, and a shaft holder alignedly mounting between the upper and lower joints to form a reinforcement channel. The reinforcing shafts are disposed within the reinforcement channels and coupling between the upper and lower joints through the shaft holders respectively, wherein each of the reinforcing shafts has an upper portion received in a respective upper socket of the upper joint, a lower portion received in a respective lower socket of the lower joint, and a mid-portion received within the respective shaft holder such that the joint structure reinforces the a strength between the top and bottom retention frames to rigidly support the wall frame.
