Herein, we introduce a fully stretchable lithium-ion battery system for free-form configurations in which all components, including electrodes, current collectors, separators, and encapsulants, are intrinsically stretchable and printable. The stretchable electrode acquires intrinsic stretchability and improved interfacial adhesion with the active materials via a functionalized physically cross-linked organogel as a stretchable binder and separator. Intrinsically stretchable current collectors are fabricated in the form of nanocomposites consisting of a matrix with excellent barrier properties without swelling in organic electrolytes and nanostructure-controlled multimodal conductive fillers. Due to structural and materials freedoms, we successfully fabricate several types of stretchable lithium-ion battery that reliably operates under various stretch deformations with capacity and rate capability comparable with a nonstretchable battery over 2.5 mWh cm English American Chemical Society Intrinsically Stretchable and Printable Lithium-Ion Battery for Free-Form Configuration Article 10.1021/acsnano.1c08405 1 ACS Nano, v.16, no.2, pp.2271 - 2281 ACS Nano 16 2 2271 2281 N scie scopus 000746854800001 2-s2.0-85123924992 Chemistry, Multidisciplinary Chemistry, Physical Nanoscience & Nanotechnology Materials Science, Multidisciplinary Chemistry Science & Technology - Other Topics Materials Science Article; Early Access stretchable lithium-ion battery physically cross-linked organogels stretchable current collector all-component intrinsically stretchable battery printing on stretch fabric
