Special Issue Information

Dear Colleagues,

Advanced energy storage devices are emerging as essential technologies in a variety of fields, including electric vehicles (EVs), energy storage systems (ESSs), power implantable biomedical devices, and wearable devices. Various metal oxide materials are being investigated to improve the performance of these advanced energy storage devices. This Special Issue will feature the latest research results on metal oxide materials and applications for advanced energy storage. It will focus on research results on next-generation electrode active materials and electrolyte materials for all-solid-state batteries and lithium-ion batteries. This special issue and contains but is not limited to the following topics:

  • Advanced electrode active materials;
  • Improved energy density;
  • Improved capacity and life;
  • Improved safety Oxide-based solid electrolytes for all-solid-state batteries;
  • Improved ionic conductivity;
  • Improved stability;
  • Reduced interfacial resistance.

The growing need for lithium-ion batteries, fueled by the widespread use of electric vehicles (EVs) and portable electronic devices, requires high energy density and safety. The cathode material Li1-x(NiyCozMn1-y-z)O2 (NCM) shows promise, but attaining high efficiency necessitates optimization of both composition and manufacturing methods. Polycrystalline LiNiCoMnO2 powders were synthesized and assessed in this investigation using a polyvinyl alcohol (PVA) solution method. The study examined different synthesis conditions, such as the PVA to metal ions ratio and the molecular weight of PVA, to assess their influence on powder characteristics. Electrochemical analysis indicated that cathode materials synthesized with a relatively high quantity of PVA with a molecular weight of 98,000 exhibited the highest discharge capacity of 170.34 mAh/g and a high lithium-ion diffusion coefficient of 1.19 × 10−9 cm2/s. Moreover, decreasing the PVA content, irrespective of its molecular weight, led to the production of powders with reduced surface areas and increased pore sizes. The adjustments of PVA during synthesis resulted in pre-sintering observed during the synthesis process, which had an impact on the long-term stability of batteries. The electrodes produced from the synthesized powders had a positive impact on the insertion and extraction of Li+ ions, thereby improving the electrochemical performance of the batteries. This study reveals that cathode materials synthesized with a high quantity of PVA with a molecular weight of 98,000 exhibited the highest discharge capacity of 170.34 mAh/g and a high lithium-ion diffusion coefficient of 1.19 × 10−9 cm2/s. The findings underscore the significance of optimizing methods for synthesizing PVA-based materials to enhance the electrochemical properties of NCM cathode materials, contributing to the advancement of lithium-ion battery technology. The findings underscore the significance of optimizing methods for synthesizing PVA-based materials and their influence on the electrochemical properties of NCM cathode materials. This contributes to the continuous progress in lithium-ion battery technology. Full article
