Tough hydrogel has attracted considerable interest in various fields, however, due to poor biocompatibility, nondegradation, and pronounced compositional differences from natural tissues, it is difficult to be used for tissue regeneration. Here, a gelatin‐based tough hydrogel (GBTH) is proposed to fill this gap. Inspired by human exercise to improve muscle strength, the synergistic effect is utilized to generate highly functional crystalline domains for resisting crack propagation. The GBTH exhibits excellent tensile strength of 6.67 MPa (145‐fold that after untreated gelation). Furthermore, it is directly sutured to a ruptured tendon of adult rabbits due to its pronounced toughness and biocompatibility, self‐degradability in vivo, and similarity to natural tissue components. Ruptured tendons can compensate for mechanotransduction by GBTH and stimulate tendon differentiation to quickly return to the initial state, that is, within eight weeks. This strategy provides a new avenue for preparation of highly biocompatible tough hydrogel for tissue regeneration.

A hybrid system electrode made from a biomass-based material sodium lignosulfonate-derived hierarchical porous graphitic carbon (PGLS) and an organic redox compound (alizarin) is demonstrated. A derivative of alizarin called “alizarin red S” (ARS) improves energy storage capacity while PGLS-1 synthesized from high-molecular-weight sodium lignosulfonate (LS), using K2FeO4 to achieve synchronous carbonization and graphitization, provides a continuous 3D porous framework with a certain graphitic order for the bulk charge transport and ARS self-organization within the composite electrode. The composite ARS/PGLS-1 electrode exhibits outstanding gravimetric specific capacitances (469.5 and 200.2 F g−1 at current densities of 0.5 and 10.0 A g−1, respectively, for the ARS/PGLS-1 = 1 sample), indicating that ARS is compatible with PGLS-1 carbon-based supercapacitor systems that can be produced on a large scale. Furthermore, the assembled symmetric prototype redox-enhanced supercapacitor (SPRS) in an aqueous gel electrolyte (PVA/KOH/ARS) is demonstrated to have considerable specific capacitance, operational stability of over >2000 cycles, and synergetic energy-power output characteristics in practical applications. This new class of supercapacitors based on biomass materials represents a significant step toward green and sustainable energy storage technologies.
