“…The previous areal energy and power densities are in general larger than or comparable with those of other representative batteries recently reported in the literature (Figure 3c). [24][25][26][27][28][29][30][31][32][33][34] Especially, our AgCl AMB reconciles the power density with the energy density. Even if the power density is enhanced by 18 times (from 0.78 to 14 mW cm À2 ), the energy density is just reduced by about 20% (from 8.98 to 7.26 J cm À2 ).…”

Silver is needed for various energy storage or conversion devices involving batteries and solar cells. Herein, a method for recycling silver elements from Mg/AgCl batteries to heterojunction solar cells is reported. A surfactant‐assisted solvothermal route is presented to synthesize AgCl polyhedral microparticles in ethylene glycol at 160 °C. Some AgCl are reduced to Ag after electron irradiation. The AgCl–Ag hybrid materials can be utilized as aqueous magnesium battery‐conductive additive‐free cathodes and deliver a high power density of 14 mW cm−2 at 10 mA cm−2. Ag nanoparticles (NPs) with a diameter in the range of 50–200 nm are obtained through the discharge reaction of AgCl cathodes. Benefiting from their excellent filling and sintering effects, the introduction of Ag NPs significantly improves the conductivity of silver pastes, whose resistivity and contact resistance are decreased by 67% and 68%, respectively. Solar cells that use the previous silver pastes are shown to promote a ≈1.2 times increase in power conversion efficiency and achieve 25.13%. The increased electricity generation is estimated to reach 66 kW h m−2 every year.

“…In the condensed phase, the exposed copper-metal centers can catalyze organic reactions such as dehydrogenation and esterification [ 48 , 49 ]. In addition, phosphoric acid derivatives also promote the formation of skeleton-stable polycyclic aromatic hydrocarbons, thereby reducing heat and mass transfer and further inhibiting combustion [ 50 , 51 , 52 ]. In the gas phase, the HPO• and PO• radicals generated during the decomposition of CuPPA-DOPO interrupt the chain reaction [ 53 ].…”

To improve the compatibility between flame retardant and epoxy resin (EP) matrix, amino phenyl copper phosphate-9, 10-dihydro-9-oxygen-10-phospha-phenanthrene-10-oxide (CuPPA-DOPO) is synthesized through surface grafting, which is blended with EP matrix to prepare EP/CuPPA-DOPO composites. The amorphous structure of CuPPA-DOPO is characterized by X-ray diffraction and Fourier-transform infrared spectroscopy. Scanning electron microscope (SEM) images indicate that the agglomeration of hybrids is improved, resisting the intense intermolecular attractions on account of the acting force between CuPPA and DOPO. The results of thermal analysis show that CuPPA-DOPO can promote the premature decomposition of EP and increase the residual amount of EP composites. It is worth mentioning that EP/6 wt% CuPPA-DOPO composites reach UL-94 V-1 level and limiting oxygen index (LOI) of 32.6%. Meanwhile, their peak heat release rate (PHRR), peak smoke production release (PSPR) and CO2 production (CO2P) are decreased by 52.5%, 26.1% and 41.4%, respectively, compared with those of EP. The inhibition effect of CuPPA-DOPO on the combustion of EP may be due to the release of phosphorus and ammonia free radicals, as well as the catalytic charring ability of metal oxides and phosphorus phases.

“…Different materials, including carbons, polymers, metals, oxides, sulfides, and selenides have been synthesized for electrochemical energy storage, electrocatalysis, and electrochem-ical detection applications. [80][81][82][83][84][85] As schematically depicted by Figure 8A, metallic materials were synthesized via electroless deposition on surface functionalized butterfly-wing followed by detemplation. Different samples, including Au, Pt, Ag, and Ni, with butterfly-wing architectures were fabricated as highperformance electrode materials.…”

Bio‐organisms with various architectures and versatile physiological functions provide a substantial bibliography for electrode design. To elucidate how bio‐organisms and bio‐schemes take effect in advanced electrode materials, this review sorts bio‐assisted construction into two categories, namely, biotemplating synthesis and biomimetic artificial fabrication. The former section summarizes unique characteristics of different biotemplates for electrode preparation, including “bottom‐up” structural designability of biomolecules, metabolism involving, and genetic alterable properties of biological cells, as well as, the structural regularity and integrity of bio‐tissues, with the aim to provide guidelines for manipulating bioarchitectures and endow biotemplating synthesis of electrodes with more designability. The later describes recent efforts in using bio‐prototypes to enhance the essential properties associated with advanced electrodes, including mechanical properties, wettability, mass transport, electron/charge transfer, and catalytic activity, with intensive concerns on the function principles of biomimetic designs in electrochemical systems. Then, advances in applications of bioderived and biomimetic electrode materials are summarized emphasizing how bio‐structures/components and bionic designs help to enhance the charging/discharging and electrocatalytic performance in specific electrochemical energy storage and conversion systems. Finally, future trends with prospects and challenges for developing new bioderived/biomimetic electrode materials, as well as, related conceptual innovation on bionics, are discussed in the last section.
