“…More than expected, the capacitance retention at 60 °C is 115.2 % compared to that at room temperature. This is attributed to the accelerated ions flow in the electrolyte due to increasing temperatures, which allows more electrolyte ions to reach the electrode bulk, thereby improving the specific capacitance [55] . Apparently, the supercapacitor was a reliable energy storage solution capable of functioning effectively under certain low‐temperature and high‐temperature conditions.…”

Preparation of flexible supercapacitors with excellent mechanical properties and self‐healing properties is of great significance but still remains a challenge. A self‐healable conductive hydrogel based on poly N‐hydroxyethyl acrylamide (PHEAA) is fabricated as electrolyte for supercapacitors. The design of the physically cross‐linked dual network, and rich hydrogen bonds endow the hydrogel with robust mechanical properties and strong self‐healing ability. The hydrogel exhibited an excellent stretchability (723%) and a high ionic conductivity (21.8 mS/cm). Specially, by in‐situ growth of electrode film, a non‐laminated supercapacitor is obtained with flexibility and self‐healing ability. Due to the non‐laminated structure, the supercapacitor can work stably under bending and punching. The supercapacitor possessed an areal capacitance of 253.1 mF/cm2 and the capacitance retention was 80% after five cutting‐healing cycles. The pseudo‐capacitance contribution of the supercapacitor after self‐healing was discussed. It is noteworthy that the supercapacitor maintains the ability to power a clock after self‐healing.

“…A 0.2 mol/L glucose solution was then added as a reducing agent for silver ions and finally dried at 60 °C for 4 h to obtain CCP@Ag composite paper-based materials. By varying the reduction times (20,40,60, 80, 100 min), we obtained different CCP@Ag composite papers, which were labeled as CCPA-20, CCPA-40, CCPA-60, CCPA-80, and CCPA-100, respectively.…”

With the continuous improvement of living standards and advancements in science and technology, composite materials with multiple functionalities are gaining high practical value in modern society. In this paper, we present a multifunctional conductive paper-based composite with electromagnetic (EMI) shielding, sensing, Joule heating, and antimicrobial properties. The composite is prepared by growing metallic silver nanoparticles inside the cellulose paper (CP) modified with polydopamine (PDA). The resulting CP@PDA@Ag (CPPA) composite has high conductivity and EMI shielding properties. Furthermore, CPPA composites demonstrate exceptional sensing, Joule heating, and antimicrobial properties. In addition, Vitrimer, a polymer with excellent cross-linked network structure, is introduced into CPPA composites to obtain CPPA-V intelligent electromagnetic shielding materials with shape memory function. These excellent properties show that the prepared multifunctional intelligent composite has exceptional EMI shielding, sensing, Joule heating, and antibacterial and shape memory properties. In short, this multifunctional intelligent composite material has great application prospects in flexible wearable electronics.

“…Among the many electrochemical energy storage technologies, lithium-ion batteries are widely used in mobile electronic devices due to their excellent self-discharge performance and portability, showing a broad application prospect [ 1 ]. In addition, supercapacitors [ 2 , 3 , 4 ] and zinc-air batteries [ 5 ], which have high energy density and excellent safety, have also received wide attention from researchers. Since the capacity of conventional graphite electrodes of lithium-ion batteries is close to the theoretical maximum, it cannot meet the demand.…”

Silicon-based anode materials are considered one of the highly promising anode materials due to their high theoretical energy density; however, problems such as volume effects and solid electrolyte interface film (SEI) instability limit the practical applications. Herein, silicon nanoparticles (SiNPs) are used as the nucleus and anatase titanium dioxide (TiO2) is used as the buffer layer to form a core-shell structure to adapt to the volume change of the silicon-based material and improve the overall interfacial stability of the electrode. In addition, silver nanowires (AgNWs) doping makes it possible to form a conductive network structure to improve the conductivity of the material. We used the core-shell structure SiNPs@TiO2/AgNWs composite as an anode material for high-efficiency Li-ion batteries. Compared with the pure SiNPs electrode, the SiNPs@TiO2/AgNWs electrode exhibits excellent electrochemical performance with a first discharge specific capacity of 3524.2 mAh·g−1 at a current density of 400 mA·g−1, which provides a new idea for the preparation of silicon-based anode materials for high-performance lithium-ion batteries.
