Self-wound nanomembranes from functional multilayered structures can improve lithium storage performance report Yongfeng Mei and co-workers on p. 4591. Intrinsic strain is relaxed by rolling; the composite components are uniformly dispersed; the micro/nanohierarchical structure assumes a mixed ion/electron conduction network; and the conventional nanomembrane deposition techniques allow for various materials combinations, making the technique suitable for meeting different demands in lithium ion batteries.
