Nanocarbon applications in anode-free batteries
Year: 2024
Type: article
Abstract: Anode-free batteries (AFBs), distinguished by the absence of a prefabricated anode, present a promising avenue for achieving higher energy densities and simplified manufacturing in energy storage systems. This review meticulously explores the pivotal role of nanocarbons in enabling the successful implementation of AFBs across diverse chemistries, including Li-, Na-, K-, Al-, Zn-metal batteries, and Li-S, Na-S batteries, as well as Zn-air, Zn-MnO2, Na–CO2 batteries. The diverse allotropes of carbon, ranging from 1D (carbon nanotubes, CNTs and carbon nanofibers, CNFs), 2D (graphene and its derivatives) 3D (carbon cloth, carbon paper, etc.) structures, exhibit unique properties that can be strategically harnessed to address key challenges such as dendrite growth and unstable SEI formation in AFBs. The multifaceted applications of nanocarbon in AFBs, encompassing protective coatings on current collectors, free-standing electrodes, separator modifications, and cathode enhancements will be discussed. The concept of metalphilicity, crucial for tailoring carbon surfaces to facilitate uniform metal deposition and suppress dendrite formation, is also elucidated. This perspective provides a comprehensive framework for discussing the application of nanocarbon materials in AFBs, covering their roles, mechanisms, recent developments, challenges, and future perspectives.
