Custom-Made Electrochemical Energy Storage Devices

Abstract

A customizable electrochemical energy storage device is a key component for the realization of next-generation wearable and biointegrated electronics. This Perspective begins with a brief introduction of the drive for customizable electrochemical energy storage devices. It traces the first-decade development trajectory of the customizable electrochemical energy storage devices. It then discusses the challenges and future directions, calling for such devices that allow users to select, design, and change the properties (including capacity, flexibility, shapes, and functionalities) according to real-life needs. Leveraging these customizable electrochemical energy storage devices will shed light on smarter programmable electrochemical energy storage devices to power future wearable and biointegrated electronics.
