“…When cellulose acted as a reinforcement material and was sandwiched in two layers of (Er 0.5 Nb 0.5 ) 0.05 Ti 0.95 O 2 /PEO/LiTFSI (Figure 2d and 2e), the CPEs‐based Li‐LiFePO 4 (LFP) cells exhibited superb cycling stability (capacity retention of 97.6 % at 0.2 C after 100 cycles), showing good suppression of lithium dendrites (Figure 2f). [77] All of these results indicated that polysaccharides could be used as reinforcement materials.…”

Solid-state batteries have become one of the hottest research areas today, due to the use of solid-state electrolytes enabling the high safety and energy density. Because of the interaction with electrolyte salts and the abundant ion transport sites, natural polysaccharide polymers with rich functional groups such as À OH, À OR or À COO À etc. have been applied in solid-state electrolytes and have the merits of possibly high ionic conductivity and sustainability. This review summarizes the recent progress of natural polysaccharides and derivatives for polymer electrolytes, which will stimulate further interest in the application of polysaccharides for solid-state batteries.

“…Typically, a sandwich cellulose-based all-solid-state electrolyte is prepared by Zheng et al, [44] which exhibits good mechanical stability and wide electrochemical window (4.3 V). However, there is still room for improvement in room temperature ionic conductivity (~1 × 10 À 5 S cm À 1 ) and Li + transference number (0.47 at 60 °C) of the prepared electrolyte.…”

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.

“…Many past research studies indicate that CPE with sandwich architectural design could stand a great chance to alleviate these issues. Accordingly, the sandwich-architectured CPE can not only decrease the interfacial resistance between the electrolyte and electrode but also help to suppress Li dendrite growth. − For instance, Wang et al . fabricated a PEO solid polymer electrolyte–LATP sheet sandwiched electrolyte, which secured a high ionic conductivity of 4 × 10 –5 S cm –1 at room temperature, ascribed to the significantly reduced interfacial resistance .…”

High-performance solid-state lithium-metal batteries (SSLMBs) require solid electrolytes displaying outstanding electrochemical stability, excellent ionic conductivity, and high Li+ ion transference number. On top of these, it should also be compatible with the electrodes applied and functionable under room temperature. To achieve these, a solution-casting technique is proposed herein to prepare a flexible composite polymer electrolyte (CPE), which is equipped with a high ionic conductivity and Li+ ion transference number, concurrently applicable in the construction of high-voltage solid-state Li batteries. The proposed CPE, which is made up of poly(vinylidene difluoride-co-hexafluoropropylene) (PVDF-HFP)/polypropylene carbonate (PPC) blend with an Al-doped Li7La3Zr2O12 (Al-LLZO) filler, was sandwiched between PVDF-HFP/PPC–lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) skin layers with SN plasticizer added. This formulation of PVDF-HFP/PPC/Al-LLZO/LiTFSI/SN was abbreviated as sandwich-PPA in our study. Such configuration permits notable resistance reduction at the electrode–electrolyte interface while suppressing Li dendrite growth throughout the robust charging–discharging process. This can be attributed to the excellent performance of the sandwich composite electrolyte membrane, which promises high ionic conductivity (ca. 4.04 × 10–4 S cm–1) and a high Li+ ion transference number (ca. 0.583) at room temperature. A CR2032 coin cell, which is assembled with Al2O3-C@NCA/Sandwich-PPA/Li, delivered a high specific capacity (186.20 mAh g–1 at 0.1C at room temperature), along with its excellent rate performance and cycle stability (discharge capacity of 126.23 mAh g–1; capacity retention of 80.03% after 100 cycles at a rate of 0.5C at room temperature). This verified the potential of our novelty-formulated solid-state electrolyte to secure excellent performance of SSLMBs.
