Porous carboxymethyl cellulose carbon of lignocellulosic based materials incorporated manganese oxide for supercapacitor application

Design of a Cellulose-Based Supercapacitor Based on Polymerization-Doping Phase Inversion of a Polydopamine-Modified Separator and a Polypyrrole/Graphene-Doped Membrane Electrode

“…and are expected to be widely used in various electronic equipment, information products, electric vehicles, and other industrial fields. 1 The key raw materials of SCs mainly come from traditional unsustainable fossil fuel coal, petrochemicals, and other raw materials. 2 Cellulose and its processed products have their own green labels, which are renewable, non-toxic, low-cost to manufacture, easy to modify physically or chemically, and widely used in pulping and papermaking, fiber functionalization, fiber fabrics, medical degradable materials, and other fields.…”

“…Facing the ever-increasing energy demand, supercapacitors (SCs) can not only store energy like traditional batteries but also have the advantages of ultrahigh capacitance, fast charge and discharge, good low temperature performance and safety, etc. and are expected to be widely used in various electronic equipment, information products, electric vehicles, and other industrial fields . The key raw materials of SCs mainly come from traditional unsustainable fossil fuel coal, petrochemicals, and other raw materials .…”

Preparation of Octahedral Mn3O4 by Liquid Phase Method

“…In recent years, octahedral manganese trioxide had been widely used in lithium battery industry [8]. Studies by many scholars had shown that compared with manganese dioxide as manganese source, LiMn 2 O 4 synthesized by octahedral manganese trioxide had better electrochemical properties, which could significantly improve the specific capacity and stable rate performance of battery materials [9][10][11][12]. In addition, both octahedral manganese trioxide and lithium manganate had spinel structure.…”

Sodium Carboxymethylcellulose as Versatile Biotemplates of Zeolitic Imidazolate Frameworks for Reduced Graphene Oxide-/N-Doped Porous Carbon Hydrogel Electrodes for Supercapacitors

“…CMC has properties similar to cellulose such as abundant sources in nature, excellent chemical stability, renewability, nontoxic nature, environmentally benign nature, and good biocompatibility . Also, the same time, CMC presents high water solubility because it possesses several hydroxyl and carboxylate groups, which solves the problem of complicated and time-consuming dissolution of cellulose-based materials . In addition, it could undergo a cross-linking reaction with metal ions to improve its structure and properties, and porous carbon materials with appropriate porosity could be obtained after a simple high-temperature calcination process .…”

“…24 Also, the same time, CMC presents high water solubility because it possesses several hydroxyl and carboxylate groups, which solves the problem of complicated and timeconsuming dissolution of cellulose-based materials. 25 In addition, it could undergo a cross-linking reaction with metal ions to improve its structure and properties, and porous carbon materials with appropriate porosity could be obtained after a simple high-temperature calcination process. 26 Therefore, CMC is an excellent candidate material to be used as a template for MOF-derived porous carbon.…”
