Energy storage plays a pivotal role in the adoption of renewable energy sources, crucial for maintaining grid stability and supporting the electrification of transportation. Aqueous electrochemical systems are favored over lithium-ion batteries for their inherent safety advantages. Despite these benefits, the lower energy and power densities of aqueous systems pose significant challenges. The advent of two-dimensional (2D) nanomaterials proposes a solution through their remarkable attributes such as high specific surface areas, atomic thinness, and adaptability in structural properties, potentially revolutionizing aqueous electrochemical energy storage (AES) applications.
This Research Topic aims to push the boundaries of aqueous electrochemical energy storage technologies, exploring the potential of 2D nanomaterials in enhancing the performance and efficiency of AES devices. We are particularly interested in understanding the synthesis of these materials, their interaction at molecular levels, and their operational capabilities in energy storage systems.
To gather further insights within the realms of nanomaterial-enhanced energy storage, we welcome articles addressing, but not limited to, the following themes:
• Scalable production and precise characterization of innovative 2D nanosheets such as graphene, and other relevant compounds tailored for AES.
• Advanced interface engineering tools including surface treatments and heteroatom incorporation for improved ion dynamics and energy transfer.
• Integration and experiential analysis of complete cells featuring 2D nanomaterials, exploring both gel and solid-state electrolytes in aqueous solutions.
• Up-to-date in-situ and operando diagnostic studies to unearth the operational mechanisms at the nanolevel.
• Comprehensive computational studies to decode behaviors impacting longevity and performance at atomic scales.
