“…In 2018, Reyes et al developed a fully printed and customized LIB with an FDM 3D printer, and integrated it with sunglasses and LED bracelets. [ 35 ] Recently, Lee et al coupled LiNi 0.8 Co 0.15 Al 0.05 O 2 (NCA) as cathode material and natural graphite as anode material to assemble the fully printed flexible battery, [ 36 ] and broadened the application of the integrated design with glass frame and Bluetooth headset. These progresses raise the possibility of developing the next‐generation batteries of various forms for wearable devices.…”

The depletion of fossil fuel resources and the emerging climate crisis triggered the development in advanced technology for renewable and environmentally friendly energy storage.Electrochemical energy storage (EES) devices, such as rechargeable batteries and electrochemical supercapacitors (SCs), represent a promising and efficient energy storage system with high energy and power densities. [1] SCs store charges by adsorbing ions near the surface of electrode materials or undergo fast reversible surface faradaic redox reactions while storing charges. They are known for their long life cycle (>10 000 times), fast chargedischarge capability, high power density, and safety. [2] However, SCs suffer from low energy density (10-20 Wh kg À1 ). [3] Compared with SCs, batteries store energy in the form of chemical energy through the reversible insertion of ions, such as univalent ions (i.e., H 3 O þ , Li þ , Na þ , or K þ ) or multivalent ions (i.e., Zn 2þ , Mg 2þ , Ca 2þ , or Al 3þ ), into the electroactive host materials. Normally, they have a relatively high energy density of 30-170 Wh•kg À1 , but much longer charging time due to a lower power density. With the ever-growing energy demand for electric vehicles, smart grid and large-scale stationary electrical energy storage systems for solar conversion, wind power, hydroelectricity, and bioenergy EESs that possess a high energy density, power capability, fast charging/discharging rates, long life cycles, as well as a tolerance for transition currents are highly desirable.

“…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.

“…17 The most common approach nowadays consists of the printing of single components, followed by the assembly of these components in a battery device. 18 A LIB is composed of two electrodes and a separator with the main role of avoiding physical contact between them 19 while allowing the flow of lithium ions between the cathode and anode. The electrodes determine the battery capacity, as they store the lithium ions in their structure during the charge and discharge processes.…”

The growing interest in printable batteries leads to the necessity of developing new and more efficient materials that meet the required processability and performance characteristics. In this work, a poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene) (P(VDF-TrFE-CFE)) terpolymer has been used for the first time as a polymer binder for lithium-ion battery cathodes and their electrochemical characteristics have been compared with cathodes prepared with the commonly used poly(vinylidene fluoride), P(VDF), polymer binder. The rheological analysis shows that the inks show suitable properties to be printed by direct ink writing (DIW). Printing parameters were optimized with respect to the printing cathode line distance, and it is shown that the printed cathodes allowed to achieve improved battery performance when compared with conventional doctor blade-prepared electrodes, with a maximum discharge capacity of 147 mAh·g–1 at a C/8 rate. Further, it is shown that the P(VDF-TrFE-CFE) terpolymer as a new polymer binder leads to improved cathode performance (90 mAh·g–1 at a 1C rate) when compared with cathodes prepared with the commercial P(VDF) binder (80 mAh·g–1 at the 1C rate) under the same preparation method. Thus, it is shown that P(VDF-TrFE-CFE) represents a suitable binder for a new generation of high-performance batteries.
