Wood‐Derived Materials for Advanced Electrochemical Energy Storage Devices

Abstract

Over the past decade, wood‐derived materials have attracted enormous interest for both fundamental research and practical applications in various functional devices. In addition to being renewable, environmentally benign, naturally abundant, and biodegradable, wood‐derived materials have several unique advantages, including hierarchically porous structures, excellent mechanical flexibility and integrity, and tunable multifunctionality, making them ideally suited for efficient energy storage and conversion. In this article, the latest advances in the development of wood‐derived materials are discussed for electrochemical energy storage systems and devices (e.g., supercapacitors and rechargeable batteries), highlighting their micro/nanostructures, strategies for tailoring the structures and morphologies, as well as their impact on electrochemical performance (energy and power density and long‐term durability). Furthermore, the scientific and technical challenges, together with new directions of future research in this exciting field, are also outlined for electrochemical energy storage applications.

Prelithiation/Presodiation Techniques for Advanced Electrochemical Energy Storage Systems: Concepts, Applications, and Perspectives

“…On account of the aggravating environmental issues and increasing energy demand, various electrochemical energy storage (EES) systems have emerged and developed rapidly to address the encountered circumstances. [ 1–4 ] Rechargeable metal‐ion batteries are identified as one of the most promising EES systems, due to their remarkable merits, including high energy density, no memory effect, and low self‐discharge. [ 5–9 ] Lithium‐ion batteries (LIBs) are the most representative rechargeable metal‐ion batteries, which have been widely utilized in portable electronic devices, electric vehicles, and grid‐scale energy storage.…”

Revival of Zeolite‐Templated Nanocarbon Materials: Recent Advances in Energy Storage and Conversion

“…The energy crisis and environment contamination are two great issues currently threatening humanity. It is becoming urgent topic for scientists to explore environmentally benign energy storage devices [ 66–70 ] and look for renewable alternatives of traditional fuels. [ 71,72 ] Zeolite‐templated nanocarbons (ZTNCs), possessing remarkable mechanical, optical, electrical, and catalytic properties, endow them enormous potential as energy storage materials and electrocatalysts: more specifically, high specific surface area is beneficial for gas adsorption [ 73 ] and improvement of double layer capacitance; [ 55,74–79 ] the zeolite‐templated carbon frameworks with high conductivity are also suitable candidates as electrode materials [ 55,73,74,77,79–90 ] and promising scaffolds for electrocatalysts; [ 81,91–96 ] hierarchically ordered porosity can enhance mass transfer without pore blockage, [ 78,91,97–99 ] which has already been employed as the host of active materials in electrode; [ 83,85,100 ] plus ultrafine nanostructures anchored on zeolite‐templated nanocarbons, enhanced electrocatalytic performance can be implemented by synergic effect of nanocarbons and metal nanostructures.…”

Synthesis of two-dimensional lamellar porous carbon from fluorene for supercapacitors

“…And its performance is governed greatly by the electrode materials (Chen et al 2019). At present, the electrode materials of supercapacitors are mainly divided into three types: carbon-based materials (Huang et al 2019), metal oxide materials(Lee and Jang 2019), and conductive polymer materials (Xu et al 2019). Among them, carbon-based materials as the promising commercial electrode materials attract great attention.…”
