Why Cellulose‐Based Electrochemical Energy Storage Devices?

Abstract

Recent findings demonstrate that cellulose, a highly abundant, versatile, sustainable, and inexpensive material, can be used in the preparation of very stable and flexible electrochemical energy storage devices with high energy and power densities by using electrodes with high mass loadings, composed of conducting composites with high surface areas and thin layers of electroactive material, as well as cellulose‐based current collectors and functional separators. Close attention should, however, be paid to the properties of the cellulose (e.g., porosity, pore distribution, pore‐size distribution, and crystallinity). The manufacturing of cellulose‐based electrodes and all‐cellulose devices is also well‐suited for large‐scale production since it can be made using straightforward filtration‐based techniques or paper‐making approaches, as well as utilizing various printing techniques. Herein, the recent development and possibilities associated with the use of cellulose are discussed, regarding the manufacturing of electrochemical energy storage devices comprising electrodes with high energy and power densities and lightweight current collectors and functional separators.

Advanced energy materials for flexible batteries in energy storage: A review

“…The eco-materials derived separators for flexible batteries present a critical trend to integrate electrochemical energy into global clean energy scheme. [231][232][233] To meet with special targets of flexible batteries, some other polymeric materials of PVDF, PAN, and polymethyl methacrylate (PMMA) can be also processed to form microporous separators due to greater conductivity and flexibility. 88,227 As polyolefin membranes exhibit poor wettability and solvation in Na + /K + / Zn 2+ /Al 3+ -containing electrolytes, the battery chemistries beyond lithium, however, prefer glass fiber separators despite sacrificing thickness (around 300-500 mm) and flexibility.…”

High performance fully paper‐based all‐solid‐state supercapacitor fabricated by a papermaking process with silver nanoparticles and reduced graphene oxide‐modified pulp fibers

“…Paper‐based supercapacitors have gained popularity due to their inherent mechanical strength and flexibility, porosity, biocompatibility, low cost, environmental friendliness, and lightweight 7‐11 . Although cellulose paper is an insulating material, its hierarchical pores, hydrophilic surfaces make it a flexible substrate loaded with conductive materials and absorbing electrolyte 12,13 .…”

Screen-printing of microfibrillated cellulose for an improved moisture management, strength and abrasion resistant properties of flame-resistant fabrics

“…Nano-and Microfibrillated Cellulose (NMC), a biodegradable, low cost, and lightweight nanomaterial (Jonoobi et al 2015;Klemm et al 2018;Zeng et al 2020) produced from renewable resources, is also a promising nanomaterial for this segment of applications. The usage of NMC has been expanded from production of packaging, paper and board, up to flexible films, acting as thermal insulators, or new functional materials applied in electronics (Abitbol et al 2016), energy storage (Wang et al 2020), electromagnetic interference shielding (Zeng et al 2020), solar cells (Du et al 2017), (photo)catalysis (Kaushik and Moores 2016) etc. These possibilities of NMC are related to its significant physical and chemical properties, above all, high crystallinity, low density, extraordinary mechanical properties and nanoscale dimension, that give high surface area (Klemm et al 2018) with huge amounts of hydroxyl (-OH) groups available for hydrogen bonding.…”
