“…Confounding this development, however, is a challenge stemming from the conventional manufacture of energy storage devices, which result in the rigid form factors we are familiar with today (cylindrical, prismatic). Printed batteries present a means through which we could overcome this challenge, and enable integration of the battery directly into the electronics fabrication process . This would both eliminate the need for separate battery holders that are attached post‐fab, and significantly reduce the weight of the electronic device.…”

This study establishes an approach to 3D print Li‐ion battery electrolytes with controlled porosity using a dry phase inversion method. This ink formulation utilizes poly(vinyldene fluoride) in a mixture of N‐methyl‐2‐pyrrolidone (good solvent) and glycerol (weak nonsolvent) to generate porosity during a simple drying step. When a nanosized Al2O3 filler is included in the ink, uniform sub‐micrometer pore formation is attained. In other words, no additional processing steps such as coagulation baths, stretching, or etching are required for full functionality of the electrolyte, which makes it a viable candidate to enable completely additively manufactured Li‐ion batteries. Compared to commercial polyolefin separators, these electrolytes demonstrate comparable high rate electrochemical performance (e.g., 5 C), but possess better wetting characteristics and enhanced thermal stability. Additionally, this dry phase inversion method can be extended to printable composite electrodes, yielding enhanced flexibility and electrochemical performance over electrodes prepared with only good solvent. Finally, sequentially printing this electrolyte ink over a composite electrode via a direct write extrusion technique has been demonstrated while maintaining expected functionality in both layers. These ink formulations are an enabling step toward completely printed batteries and can allow direct integration of a flexible power source in restricted device areas or on nonplanar surfaces.

“…In order to address the traditional cell manufacturing‐related issues including safety, poor low electrochemical performance and mechanical properties, new fabrication processes such as multistep spray painting and screen‐printing processes have been recently investigated. With the rapid development of printing technology that is simple and reliable, printed batteries are an excellent and powerful alternative to conventional batteries for various applications that require thin, lightweight and flexibility . Recently, Sang‐Young Lee's group reported printable, flexible all‐solid‐state batteries, as shown in Figure .…”

Energy-storage technologies such as lithium-ion batteries and supercapacitors have become fundamental building blocks in modern society. Recently, the emerging direction toward the ever-growing market of flexible and wearable electronics has nourished progress in building multifunctional energy-storage systems that can be bent, folded, crumpled, and stretched while maintaining their electrochemical functions under deformation. Here, recent progress and well-developed strategies in research designed to accomplish flexible and stretchable lithium-ion batteries and supercapacitors are reviewed. The challenges of developing novel materials and configurations with tailored features, and in designing simple and large-scaled manufacturing methods that can be widely utilized are considered. Furthermore, the perspectives and opportunities for this emerging field of materials science and engineering are also discussed.

“…One of the most obvious and widely explored avenues is the development of thin, flexible and even stretchable batteries and supercapacitors that can be easily mated with the human body. [14][15][16] Such body-compliant energy storage systems are quite attractive, nevertheless, low energy capacity, poor discharge current and limited charge-discharge cycles dramatically lower their appeal for wearable applications.…”

The perspective article provides a detailed description of the major developments in the field of wearable biofuel cells. The article expounds several attributes of this newly emerging technology and its potential to address the energy needs of wearable devices. In addition to discussing important milestones reached in this field, the article also highlights the grand challenges that are presently hindering further development of wearable biofuel cells. Particular emphasis has been devoted to major issues related to biofuel cell stability, need for generating stable, high levels of power, mechanical compliance and resiliency and device aesthetics. In addition to this, the article also offers multiple pathways to address these issues. The article aims at generating interest among researchers with diverse expertise to come together on a common platform to overcome the major challenges faced by the field of wearable biofuel cells. Such collaborative efforts will be essential for the success of wearable biofuel cells and to harness their full potential. Why Biofuel Cells for Wearable Applications?Recent development of bio-integrated wearable electronics that provide continuous information, 1,2 entertainment, 3,4 help in carrying out routine activities 5 are a result of our insatiable desire to develop technologies that make lives easy. The nascent field of body-bound electronics is still is in its infancy and there exists several challenges that ought to be addressed for successful adaptation of the technology by various market segments. [6][7][8][9] Identifying suitable wearable energy sources is one of the biggest omnipresent challenge that cuts across almost all wearable electronics fields. 10 The situation is getting further exacerbated as the field of wearable electronics advances toward developing tiny, yet complex, multi-tasking wearable devices that continuously require high levels of energy supply for optimal performance. Research efforts to overcome this issue can be broadly classified into developing low-energy electronics, 11 adaptive algorithms for intelligent, low-power consuming electronics 12 and high energy density power sources. 13 Of these, development of efficient power sources has attained the greatest attention. Usage of conventional power sources, such as, lithium ion and alkaline batteries result in increased bulkiness and rigidity of the wearable electronics wherein just a fraction of the device weight is due to electronics while the rest is because of the battery. Such integration of conventional power sources with wearable electronics thus vitiates the overall attractiveness of the wearable system. Hence, there has been a genuine effort within the scientific community toward developing new formats of power sources for wearable applications. One of the most obvious and widely explored avenues is the development of thin, flexible and even stretchable batteries and supercapacitors that can be easily mated with the human body.14-16 Such body-compliant energy storage systems are quite attracti...
