Abstract: A battery module and a battery pack employing the battery module are provided. The battery module includes a cell and a heat-dissipation and pressure-relief component. The heat-dissipation and pressure-relief component is provided with a liquid-cooling partition and a smoke-exhaust and pressure-relief portion. The smoke-exhaust and pressure-relief portion is provided with a pressure-relief channel and an exhaust port communicating with the pressure-relief channel. The liquid-cooling partition is arranged at one side of the pressure-relief channel and is vertically connected to the smoke-exhaust and pressure-relief portion. An explosion-proof valve of the cell is arranged corresponding to the exhaust port, and the cell exchanges heat with the liquid-cooling partition.

Abstract: A method for operating in a borehole penetrating a formation is disclosed. The method includes disposing in the borehole an assembly comprising a load-bearing and oil-disintegrable tool comprising a polymeric composite; performing a downhole operation; and disintegrating the load-bearing and oil-disintegrable tool with a hydrocarbon fluid. The polymeric composite comprises an oil-disintegrable polymer which is one or more of the following: a polydicyclopentadiene, polypropylene, polyurethane, polycarbonate, polysulfone, or a high density polyethylene, the polyurethane being a polyhedral oligomeric silsesquioxane-modified polyurethane, a lauryl methacrylate graft polyurethane copolymer, a divinylbenzene crosslinked polyurethane, or a combination comprising at least one of the foregoing.
