Abstract: Provided are an electrolytic copper foil, an electrode and a lithium-ion cell comprising the same. The electrolytic copper foil has a first surface and a second surface opposite the first surface. An absolute difference of the FWHM of the characteristic peaks of (111) planes of the first surface and the second surface analyzed by GIXRD is less than 0.14, the first and the second surfaces each have a nanoindentation hardness of 0.3 GPa to 3.0 GPa, and the yield strength of the electrolytic copper foil is more than 230 MPa. By controlling the absolute difference of the FWHM of the characteristic peaks of (111) plane of these two surfaces, the nanoindentation hardness of these two surfaces and the yield strength, the electrolytic copper foil can have improved tolerance to the repeated charging and discharging and reduced warpage, thereby improving the yield rate and value of the lithium-ion cell.

Abstract: An energy conversion device includes a gas cylinder having a cylinder body, and a piston guided to move along a direction. The cylinder body includes an annular partition wall unit extending from a base plate and defining a piston chamber. The piston includes a plug and an annular fence unit. Clearances are formed between the plug and the partition wall unit, and between the partition wall unit and the fence unit such that the partition wall unit does not contact the plug and the fence unit. The plug, the fence unit and the partition wall unit define a surrounding chamber unit around the piston chamber. When the plug moves toward the base plate to compress gas within the piston chamber, gas within the surrounding chamber unit is also compressed to thereby establish a gas-tight seal between the plug and the partition wall unit.
