Our modern and technological society requests enhanced energy storage devices to tackle the current necessities. In addition, wearable electronic devices are being demanding because they offer many facilities to the person wearing it. In this manuscript, a historical review is made about the available energy storage devices focusing on super-capacitors and lithium-ion batteries, since they currently are the most present in the industry, and the possible polymeric materials suitable on wearable energy storage devices. Polymers are a suitable option because they not only possess remarkable mechanical resistance, flexibility, long life-times, easy manufacturing techniques and low cost in addition to they can be environmentally friendly, nontoxic, and even biodegradable too. Moreover, the electrical and electrochemical polymer properties can be tunning with suitable fillers giving to versatile conducting polymer composites with a good cost and properties' ratio. Although the advances are promising, there are still many drawbacks that need to be overcome. Future research should focus on improving both the performance of materials and their processability on an industrial scale, where additive manufacturing offers many possibilities. The sustainability of new energy storage devices should not

“…GPEs can also act as a separator by serving as a physical barrier between the electrodes, exhibiting the cohesive and diffusive properties of solid and LEs [ 16 , 17 , 18 ]. Similar to LEs, GPEs exhibit excellent ionic conductivity and electrochemical stability [ 19 , 20 ]. GPEs are usually prepared by immersing a porous polymer membrane in an LE.…”

The development of gel polymer electrolytes (GPEs) for lithium-ion batteries (LIBs) has paved the way to powering futuristic technological applications such as hybrid electric vehicles and portable electronic devices. Despite their multiple advantages, non-aqueous liquid electrolytes (LEs) possess certain drawbacks, such as plasticizers with flammable ethers and esters, electrochemical instability, and fluctuations in the active voltage scale, which limit the safety and working span of the batteries. However, these shortcomings can be rectified using GPEs, which result in the enhancement of functional properties such as thermal, chemical, and mechanical stability; electrolyte uptake; and ionic conductivity. Thus, we report on PVDF-HFP/PMMA/PVAc-based GPEs comprising poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-co-HFP) and poly(methyl methacrylate) (PMMA) host polymers and poly(vinyl acetate) (PVAc) as a guest polymer. A physicochemical characterization of the polymer membrane with GPE was conducted, and the electrochemical performance of the NCM811/Li half-cell with GPE was evaluated. The GPE exhibited an ionic conductivity of 4.24 × 10−4 S cm−1, and the NCM811/Li half-cell with GPE delivered an initial specific discharge capacity of 204 mAh g−1 at a current rate of 0.1 C. The cells exhibited excellent cyclic performance with 88% capacity retention after 50 cycles. Thus, this study presents a promising strategy for maintaining capacity retention, safety, and stable cyclic performance in rechargeable LIBs.

Advances in additive manufacturing are leading to the emergence of new printable applications, including sensors for healthcare monitoring and bioengineering scaffolds. Research is driven by designing new printable inks including composites that can be extruded and respond to changes in their surroundings and patterning these materials on the microscale. In modern printing techniques, an emerging modified three‐dimensional (3D) printing method: materials extrusion has been utilized for customizable electronics because of its high compatibility with various inks, low cost, and versatility to different levels of complexity. Material extrusion enables not only the printing of 2D and 3D architecture of the electrode structure but also the bioprinting of structures such as conductive scaffolds. In this review, fundamental insights into rational printable ink formulation including colloidal suspensions, gels, polymer melts, composites, printing criteria, processes, and applications toward printable electronics using composites composed of nanomaterials and biopolymers are fully discussed. New manufacturing insights on how to further improve the resolution and simplify the printing process of responsive materials are discussed, which have not been seen in currently published representative reviews. It is envisioned that this review provides high scientific merits to readers working in wearable devices, biological smart materials, and flexible nanoelectronics.
