Abstract

A flexible node-type lithium-ion battery (LIB) with novel postpatterned electrodes is developed via a simple, one-step process involving an imprinting step of a conventional electrode in the presence of a flattened mesh template. The node-type LIBs containing segmented parts for energy storage and mechanical deformation demonstrate a good cycle stability.
