“…To develop greener Li-S batteries, natural and readily available biomass-derived materials, such as cellulose [174], zein protein [175] and chitosan [176], have also been introduced into GPEs as fillers. Nair et al [174] studied for the first time the performance of nanocellulose-embedded CGPE for Li-S cells.…”

“…Since the addition of nanoscale cellulose increased the porosity of the polymer network and acted as a polysulfides barrier, the assembled cells exhibited more liquid electrolytes retention and better cycling stability (initial capacity of 730 mAh g À1 at 1C). Ding et al [175] reported the ultra-durable gel electrolytes (u-CGEs) via integrating zein protein nanofibers on N-doped carbon nanofibers (Fig. 9f).…”

Amid burgeoning environmental concerns, electrochemical energy storage has rapidly gained momentum. Among the contenders in the "beyond lithium" energy storage arena, the magnesium-sulfur (Mg/S) battery has emerged as particularly promising, owing to its high theoretical energy density. However, the gap between fundamental research and practical application is still hindering the commercialization of Mg/S batteries. Here, through reviewing the recent developments of Mg/S batteries technologies, especially with respect to energy density and cost, we present the primary technical challenges on both materials and device level to surpass the energy density and cost-effectiveness of lithium-ion battery. While the high electrolyte-sulfur ratio and the expensive liquid electrolyte are significantly limiting the practical application of Mg/S batteries, we found that solid-state Mg electrolyte appears to be a feasible solution on the basis of energy density and cost evaluation.

Asymmetric supercapacitors (ASCs) have attracted significant attentions worldwide owing to their wider voltage window compared with symmetric supercapacitors (SCs). Through combinations of two electrodes with different charge storage mechanisms or different redox reactions, extended operating voltage window can be realized for ASCs. In this article, first the ASCs are classified into two types based on different charge storage mechanisms: electric double‐layer capacitive (EDLC)//pseudocapacitive‐type ASCs and EDLC//battery‐type hybrid SCs. For the EDLC/pseudocapacitive‐type ASC, carbon materials are adopted as anode and transition metal oxides including MnO2, RuO2, etc., are utilized as cathodes. For EDLC//battery‐type hybrid SCs, carbon materials as anode are combined with metal oxide/hydroxide such as NiO, and Ni(OH)2, etc., as cathode. Recently, Li‐ion‐based ASCs composed of carbon materials and Li‐ion battery‐type electrode materials with a Li‐containing organic electrolyte show great potentials to be promising alternatives. Some metal oxides/nitrides including InO2, Bi2O3, Fe3O4, Fe2O3, and VN can work in a negative potential range. By coupling another battery/pseudocapacitive electrode, all redox‐type ASCs are assembled and their electrochemical performances are widely studied. Then, based on the above categories recent advances of ASCs are summarized. Finally, the challenges and prospects for the development of ASCs are pointed out from perspectives of this study.
