“…The platform of G ′ of ChNCs was between 10 1 and 10 2 Pa, which was about an order of magnitude higher than that of G ″, which further verified that ChNCs are elastic solid. [ 38 ] The modulus of CCNT was about one order of magnitude higher than that of ChNCs, which indicated that MWCNT enhanced the network of ChNCs. All these results proved that CCNT ink may show good printability.…”

The screen-printing process of conductive ink can realize simple and large-scale manufacture of micro/nano patterns for producing wearable electronic products. Herein, chitin nanocrystals (ChNCs) are used as a dispersant for the preparation of multiwalled carbon nanotube (MWCNT) ink with high viscosity and uniformity by ultrasound treatment. ChNCs can interact with MWCNT in noncovalent ways, including 𝝅-𝝅 and hydrophobic interactions. ChNCs/MWCNT (CCNT) ink does not aggregate even after standing for 3 months with a maximum MWCNT concentration of 33 mg mL −1 and dispersion efficiency of 91.1%. Using CCNT ink, a paper-based thermoelectric generator (TEG) is manufactured by screen-printing technology. With good thermoelectric and strain sensing properties, CCNT coated paper can stably collect human energy at room temperature to realize self-powering. The CCNT coated paper-based TEG can convert thermal voltage signals into musical notes, monitor the changes in human behavior and respiratory rate, and monitor joint movements. Moreover, CCNT coated paper has no cytotoxicity by CCK-8 and live/dead staining. This work puts forward a strategy of green preparation of MWCNT-based ink by adding renewable chitin, which opens up a new way to apply MWCNT-based ink in self-powering wearable multifunctional sensors.

“…Very recently, a stretchable cellulose-based gel electrolyte substrate was achieved by printing a serpentine structure using nanofibrillated cellulose (NFC)/Al 2 O 3 ink (Figure 7a, 7b and 7c), while 30 wt.% Al 2 O 3 nanoparticles were added to the NFC to improve the ionic conductivity of cellulose-based gel electrolyte. [33] To obtian a stretchable LIBs, the bottom NFC/ CNT/LiFePO 4 layer is first 3D printed on the substrate, then the middle NFC/Al 2 O 3 layer is overlapped and finally the NFC/CNT/ Gr (graphite) layer is printed (Figure 7d). These two electrode layers and the gel electrolyte overlap completely, while avoiding direct contact between the upper and lower electrode layers.…”

In the coming decades, it is urgent to find a way to power the future while keeping a clean environment and strong economic growth. Thus, it is expected to transition from using fossil fuels to renewable energy. Materials based on cellulose are abundant, low cost, sustainable, possess a high surface area, good thermal stability, biocompatibility, mechanical flexibility, and inherit unique layered fiber structure from cellulose, which can act as an ideal electrolyte matrix for sustainable and high energy density lithium‐ion batteries (LIBs). In this review, we focus on energy storage application of different forms of cellulose‐based electrolytes in LIBs. Specifically, we summarize the recent advances of cellulose‐based gel and solid‐state electrolytes, focusing on the gel electrolytes based on different types of plasticizers (cellulose‐based electrolytes for flexible LIBs also are introduced). Finally, several perspectives related to the cellulose‐based‐electrolytes for LIBs are proposed based on recent progress and our own evaluation.

“…Beyond the electrodes and electrolytes, separators or membranes used in electrochemical energy storage devices have high porosity, low resistance, good elasticity, and aprotic solvent retention performance, creating additional challenges for achieving high-performance thermocells. [116][117][118] For thermocells, cross-device heat conduction is one of the main causes of low device efficiency. Therefore, inserting a separator or membrane between the two electrodes can effectively maintain the gradient of temperature and ion concentration, thus improving thermoelectric performance.…”
