Abstract:
A cell structure for a secondary battery includes an electrode assembly including a plurality of electrodes, a plurality of electrode tabs extending from the electrodes to an outside of the electrode assembly, and a plurality of lead tabs electrically connected to the electrode tabs and contacting the electrode assembly. In the cell structure, a part of each of the lead tabs is folded, and the electrode tabs are inserted into the folded part of each of the lead tabs.
Abstract:
A stretchable polymer electrolyte includes a stretchable copolymer; a lithium salt; and an organic liquid, wherein the stretchable copolymer includes a non-crosslinked first repeating unit, a non-crosslinked second repeating unit, and a crosslinked third repeating unit, the first repeating unit includes a first hard segment and a first soft segment, the second repeating unit includes a second hard segment and a second soft segment, and the third repeating unit includes a third hard segment and a third soft segment.
Abstract:
A stretchable electrode includes: a current collector; and, disposed on a surface of the current collector, a metal layer or an electrode active material layer, wherein the current collector includes a spiral-type coil spring and an elastic polymer, the spiral-type coil spring including a coil spring wound in a spiral pattern around a point, and wherein the elastic polymer is disposed in at least a portion of an inside of the coil spring, in at least a portion of a space between spiral coils of the spiral-type coil spring, or both.
Abstract:
