Self-wound nanomembranes out of functional multilayered structures were designed to improve lithium storage performance. The intrinsic strain is relaxed by rolling; the composite components are uniformly dispersed; the micro/nanohierarchical structure assumes a mixed ion/electron conduction network; and conventional nanomembrane deposition techniques allow for various materials combinations, suitable to meet different demands of lithium ion batteries.
