Nanocrystalline Cellulose-Supported Iron Oxide Composite Materials for High-Performance Lithium-Ion Batteries

Abstract

Nanocrystalline cellulose (NCC) can be converted into carbon materials for the fabrication of lithium-ion batteries (LIBs) as well as serve as a substrate for the incorporation of transition metal oxides (TMOs) to restrain the volume expansion, one of the most significant challenges of TMO-based LIBs. To improve the electrochemical performance and enhance the longer cycling stability of LIBs, a nanocrystalline cellulose-supported iron oxide (Fe2O3) composite (denoted as NCC–Fe2O3) is synthesized and utilized as electrodes in LIBs. The obtained NCC–Fe2O3 electrode exhibited stable cycling performance, better capacity, and high-rate capacity, and delivered a specific discharge capacity of 576.70 mAh g−1 at 100 mA g−1 after 1000 cycles. Moreover, the NCC–Fe2O3 electrode was restored and showed an upward trend of capacity after working at high current densities, indicating the fabricated composite is a promising approach to designing next-generation high-energy density lithium-ion batteries.

Strategies for Enhancing the Stability of Lithium Metal Anodes in Solid-State Electrolytes

“…Transition metal oxides (e.g., MnO 2 , ZnO, Fe 2 O 3 , and SnO 2 ) also have gained widespread use as electrode materials in the field of LIBs due to their more substantial theoretical capacities than graphite. Nevertheless, poor cycling performance owing to low electric conductivity and structural collapse as result of large volume expansion during lithiation/delithiation results in poor rate performance and a limited lifespan for LIBs [9]. To overcome this limitation, researchers worldwide are exploring next-generation anode materials for energy storage, including silicon and Li metal.…”

Behavior of NO3−-Based Electrolyte Additive in Lithium Metal Batteries

“…Modern power storage technology, which involves electrochemical energy storage and conversion systems, is leaning towards the development of the battery industry to make these mechanisms more sustainable and eco-friendly [1,2]. Consequently, lithium-ion batteries have gained prominence, and research to improve their performance is ongoing [3][4][5][6][7][8][9][10][11]. The largest commercial application of lithium-ion batteries is in the small wearable battery industry, but demand for them is also growing in other industries, such as computers, cell phones, laptops, cameras, and electric vehicles [12].…”
