Special Issue Information

Dear Colleagues,

Nanosized (1–100 nm) materials possesses distinct physical, chemical and electrochemical properties that could impact the cell performance of rechargeable ion-batteries. In energy storing Li-ion, Na-ion and K-ion batteries the anode and cathode materials dimensions, shape, structure and texture could play a significant role in charging and discharging time, ion-diffusion, electronic conductivity and solid electrolyte formation (typically for anodes). The designed electrode materials play a momentous role in a battery’s cycle life, energy density, cost and safety aspects. This Special Issue of the Nanomaterials journal will cover and shine light on the applications of various fascinating nanomaterials and nanoarchitectures of metals, alloys, oxides, MXenes, heteroatom doped materials and many more as electrodes for ion batteries (single to multivalent) and their overall promising energy storing performance.

An easy and environmentally friendly method was developed for the preparation of a stabilized carbon nanotube–crystalline nanocellulose (CNT–CNC) dispersion and for its deposition to generate self-standing CNT–CNC composite films. The composite films were carbonized at different temperatures of 70 °C, 800 °C, and 1300 °C. Structural and morphological characteristics of the CNT–CNC films were investigated by X-ray diffraction (XRD), Raman spectroscopy, and scanning electron microscopy (SEM), which revealed that the sample annealed at 800 °C (CNT–CNC800) formed nano-tree networks of CNTs with a high surface area (1180 m2·g−1) and generated a conductive CNC matrix due to the effective carbonization. The carbonized composite films were applied as anodes for lithium-ion batteries, and the battery performance was evaluated in terms of initial voltage profile, cyclic voltammetry, capacity, cycling stability, and current rate efficiency. Among them, the CNT–CNC800 anode exhibited impressive electrochemical performance by showing a reversible capacity of 443 mAh·g−1 at a current density of 232 mA·g−1 after 120 cycles with the capacity retention of 89% and high rate capability.
