Special Issue Information

Dear Colleagues,

Energy storage materials and devices have gained rapid development in recent years. Nanostructured electrode and electrolyte materials have been widely applied in field of advanced energy storage devices such as batteries and supercapacitors. Nanomaterials with large surface area provide richer active sites, improved ionic and electronic conductivity compared to conventional materials, which offers a significant solution for developing high-energy and high-power energy density batteries and supercapacitors. Therefore, the anodes, cathodes, and composite solid electrolytes with nanostructure play a quite key role for building advanced lithium, sodium, potassium ion/metal batteries and supercapacitors.

The aim of this Special Issue will report the recent advancements and challenges in nanomaterials used as energy storage materials and devices. It is envisaged that Special Issue will cover the applications and research of nanomaterials in energy storage systems, including metal and ion batteries (Li, Na, K, Zn), Li-S batteries, supercapacitors, solid-state batteries, energy harvesting, and their energy storage mechanisms.

The interaction between cathode and anode materials is critical for developing a high-performance asymmetric supercapacitor (SC). Significant advances have been made for cathode materials, while the anode is comparatively less explored for SC applications. Herein, we proposed a high-performance binder-free anode material composed of two-dimensional ZnFe2O4 nanoflakes supported on carbon cloth (ZFO-NF@CC). The electrochemical performance of ZFO-NF@CC as an anode material for supercapacitor application was examined in a KOH solution via a three-electrode configuration. The ZFO-NF@CC electrode demonstrated a specific capacitance of 509 F g−1 at 1.5 A g−1 and was retained 94.2% after 10,000 GCD cycles. The ZFO-NF@CC electrode showed exceptional charge storage properties by attaining high pseudocapacitive-type storage. Furthermore, an asymmetric SC device was fabricated using ZFO-NF@CC as an anode and activated carbon on CC (AC@CC) as a cathode with a KOH-based aqueous electrolyte (ZFO-NF@CC||AC@CC). The ZFO-NF@CC||AC@CC yielded a high specific capacitance of 122.2 F g−1 at a current density of 2 A g−1, a high energy density of 55.044 Wh kg−1 at a power density of 1801.44 W kg−1, with a remarkable retention rate of 96.5% even after 4000 cycles was attained. Thus, our results showed that the enhanced electrochemical performance of ZFO-NF@CC used as an anode in high-performance SC applications can open new research directions for replacing carbon-based anode materials.

The inner constituents of lithium-ion batteries (LIBs) are easy to deform during charging and discharging processes, and the accumulation of these deformations would result in physical fractures, poor safety performances, and short lifespan of LIBs. Recent studies indicate that the introduction of self-healing (SH) materials into electrodes or electrolytes can bring about great enhancements in their mechanical strength, thus optimizing the cycle stability of the batteries. Due to the self-healing property of these special functional materials, the fractures/cracks generated during repeated cycles could be spontaneously cured. This review systematically summarizes the mechanisms of self-healing strategies and introduces the applications of SH materials in LIBs, especially from the aspects of electrodes and electrolytes. Finally, the challenges and the opportunities of the future research as well as the potential of applications are presented to promote the research of this field. Full article
