Porous carbon architectures with different dimensionalities for lithium metal storage

Abstract

Lithium metal batteries have recently gained tremendous attention owing to their high energy capacity compared to other rechargeable batteries. Nevertheless, lithium (Li) dendritic growth causes low Coulombic efficiency, thermal runaway, and safety issues, all of which hinder the practical application of Li metal as an anodic material. In this review, the failure mechanisms of Li metal anode are described according to its infinite volume changes, unstable solid electrolyte interphase, and Li dendritic growth. The fundamental models that describe the Li deposition and dendritic growth, such as the thermodynamic, electrodeposition kinetics, and internal stress models are summarized. From these considerations, porous carbon-based frameworks have emerged as a promising strategy to resolve these issues. Thus, the main principles of utilizing these materials as a Li metal host are discussed. Finally, we also focus on the recent progress on utilizing one-, two-, and three-dimensional carbon-based frameworks and their composites to highlight the future outlook of these materials.

Co, Fe and N co-doped 1D assembly of hollow carbon nanoboxes for high-performance supercapacitors

“…With growing concerns on environment and sustainability, more efficient energy storage devices are highly demanded in the current energy cycle. [1][2][3] Among different types of energy storage devices, high-performance supercapacitors are of great interest because of their unique advantages, including high power density, outstanding cyclability, long life, and short charging time, that are oen not achieved in secondary batteries. 1 There are two types of energy storage mechanisms of supercapacitors, namely, electrical double-layer capacitance (EDLC) and pseudocapacitance.…”

Porous carbon nanoarchitectonics for the environment: detection and adsorption

“…Such carbons are useful in a wide variety of applications such as electrocatalysts, energy storage/conversion, fuel cells, carrier for drug delivery, adsorbents for impurities in water/ fuel, and sensing of volatile organic compounds (VOCs). [123][124][125][126][127][128][129][130] Highly porous carbons are generally obtained from various precursors, including biomasses and polymers, via hightemperature carbonization and activation [131][132][133][134][135][136] in addition to the nanocasting method. The hard templating nanocasting method requires an additional step to remove the templated materials to get the well-structured porous carbon.…”

Cationic Covalent Organic Framework as Separator Coating for High-Performance Lithium Selenium Disulfide Batteries

“…They first select a carrier material that can adsorb polysulfide and polyselenide and then encapsulate selenium disulfide in the guest material by melting. For example, they use MYS-Co 4 N@C [30], MOFs-derived 3D nanoporous Co-N-C architecture nanoboxes [31], hollow mesoporous carbon nanocubes [32], NiCo 2 S 4 hollow capsules [33], mesoporous carbon@titanium nitride hollow spheres [34], nitrogenrich carbon foam [35], and so on [36][37][38][39]. This strategy greatly improves the specific capacity and cycle stability of lithium-selenium disulfide batteries, but it also sacrifices the content of the active material, resulting in a low surface load of the active material (generally less than 2 mg cm −2 ) and the overall energy density of the battery [27].…”
