Transparent electronic devices are opening up unprecedented possibilities in display technology and virtual reality. For some of these applications, it would be advantageous if optical transparency could be combined with stretchability. Of course, all portable electronic devices need an energy source, which is ideally integrated in the form of a battery and must therefore fulfill the same physical properties. However, it is quite challenging to develop a battery in which all the components (electrodes, current collectors, separator/electrolyte, and packaging) are transparent and stretchable. Here we present the development of a transparent and stretchable full zinc ion battery comprising two electrodes deposited on a polydimethylsiloxane (PDMS) substrate and a polyacrylamide (PAM) hydrogel electrolyte. The resulting stretchable battery shows a high transmittance of 72.6% and 64.7% at 550 nm without and with 50% strain, respectively. The battery provides a capacity of 176.5 mA h g −1 after 120 cycles under varying strain conditions up to 50%. The battery's multifunctionality, linking energy storage with stretchability and transparency, makes it attractive for powering future transparent and stretchable electronics.

Multifunctional Batteries: Flexible, Transient, and Transparent

The primary task of a battery is to store energy and to power electronic devices. This has hardly changed over the years despite all the progress made in improving their electrochemical performance. In comparison to batteries, electronic devices are continuously equipped with new functions, and they also change their physical appearance, becoming flexible, rollable, stretchable, or maybe transparent or even transient or degradable. Mechanical flexibility makes them attractive for wearable electronics or for electronic paper; transparency is desired for transparent screens or smart windows, and degradability or transient properties have the potential to reduce electronic waste. For fully integrated and self-sufficient systems, these devices have to be powered by batteries with similar physical characteristics. To make the currently used rigid and heavy batteries flexible, transparent, and degradable, the whole battery architecture including active materials, current collectors, electrolyte/separator, and packaging has to be redesigned. This requires a fundamental paradigm change in battery research, moving away from exclusively addressing the electrochemical aspects toward an interdisciplinary approach involving chemists, materials scientists, and engineers. This Outlook provides an overview of the different activities in the field of flexible, transient, and transparent batteries with a focus on the challenges that have to be faced toward the development of such multifunctional energy storage devices.

“…In recent years, lithium ion batteries (LIBs) have been widely used as power sources in our daily life including in portable electronic devices such as mobile phones, laptop computers, and digital cameras; they are also promising energy sources for electric vehicles. [1][2][3][4][5][6][7][8][9][10] However, in order to be implemented in large-scale high-power systems, performance requirements are raised especially in terms of energy density, cycle life and safety issues. 3,5 Therefore, further electrode material and system developments are necessary for lithium ion batteries with higher electrochemical performance.…”
