“…Two kinds of lithium‐sulfur batteries are suggested here with good prospects, which are quasi‐solid‐state and hybrid‐electrolyte lithium‐sulfur batteries. In quasi‐solid‐state ones, the gel‐polymer electrolyte consists of liquid electrolyte and polymer matrix is consider to have good electrochemical performance . Qu et al prepared a novel sandwich‐structured gel‐polymer electrolyte, which contains nanocarbon as the physical trapping material and the additional current collector, cellulose as the chemically trapping material, and poly(ethylene glycol)‐poly(propylene glycol)‐poly(ethylene glycol) coating layer as the inhibition for lithium dendrite formation.…”

The lithium-sulfur battery is considered one of the most promising candidates for portable energy storage devices due to its low cost and high energy density.However, many critical issues, including polysulfide shuttling, self-discharge, lithium dendritic growth, and thermal hazards need to be addressed before the commercialization of lithium-sulfur batteries. To this end, tremendous efforts have been made to explore battery configurations and components, such as electrodes, electrolytes, and separators, among which the separator plays an especially critical role in addressing aforementioned issues. Thus, this review analyzes the mechanisms and interactions of these critical issues and summarizes both the function of separators and recent progress made towards remedying such issues. Additionally, promising directions for the development of separators in lithium-sulfur batteries are proposed. K E Y W O R D Slithium dendrite, lithium-sulfur batteries, self-discharge, separator, shuttle effect, thermal hazardsThe first two authors contributed equally to this work.

“…To date, most of commercial Li batteries are based on organic electrolyte. The fluidity and low flash point of organic solution easily result in the leakage and volatilization of electrolyte as well as the burning of battery devices, which deviate from the tenet of pursuing higher security of Li battery in future development direction . Especially in Li metal batteries, Li dendrites are one of major risks for battery safety.…”

“…However, owing to the insolubility in organic solvents, natural polymers are generally difficult to use directly as gel polymer skeletons to reserve organic liquid electrolytes in conventional Li batteries. Modification strategies through grafting or combining with other macromolecules have also been demonstrated . For instance, by combining starch with γ‐(2,3‐epoxypropoxy)propyltrimethoxysilane, organic electrolyte can be gelled via the chemical substitution reaction between ─OH groups and ─Si─(OCH 3 ) 3 (Figure A,B) .…”

Biomass materials are of great interest in high‐energy rechargeable batteries due to their appealing merits of sustainability, environmental benefits, and more importantly, structural/compositional versatilities, abundant functional groups and many other unique physicochemical properties. In this perspective, we provide both overview and prospect on the contributions of biomass‐derived ecomaterials to battery component engineering including binders, separators, polymer electrolytes, electrode hosts, and functional interlayers, and so forth toward high‐stable lithium–ion batteries, lithium–sulfur batteries, lithium–oxygen batteries, and solid state lithium metal batteries. Furthermore, based on the multifunctionalities of bio‐based materials, the design protocols for battery components with desired properties are highlighted. This perspective affords fresh inspiration on the rational designs of biomass‐based materials for advanced lithium‐based batteries, as well as the sustainable development of advanced energy storage devices.

Structural and compositional diversities of proteins generate a number of functions for fabricating novel and advanced materials. Recent progress in protein engineering endows flexible approaches and new functionalities, which makes the fabricated materials potentially applicable in a broad spectrum of fields. Such engineering strategies by applying proteins alone or together with other molecules derive numerous functional materials such as patterned nanometal materials/nanometallic compounds, well‐designed nanocomposites, etc. Advantages in materials’ tunability, property improvement (e.g., electronic and mechanical properties, etc.), functionalities, and biocompatibility have been demonstrated, thus providing alternatives to existing materials via conventional methods. This review summarizes and discusses the strategies of fabricating functional materials using proteins as the critical contributors. Benefiting from their versatility, proteins find their roles in engineering functional materials via acting as structure‐control agents, reaction agents, and battery components, which are emphasized in this review. The strategies of each group of functions are specifically detailed. Properties of protein‐engineered functional materials and their potential applications in the fields of microelectronics, energy storage and conversion, sensor devices, etc. are also reviewed.
