## Description

- description: Sodium-ion batteries (SIBs) are emerging as promising energy storage
    technologies, particularly for grid-scale applications, due to their low material
    costs stemming from abundant natural resources. Meeting the increasing demand
    for higher energy density requires the development of innovative electrode and
    electrolyte materials, along with advanced analytical and fabrication techniques.
    However, the energy density of SIBs is often evaluated based solely on the capacities
    and cell voltages of active materials in half-cell configurations, neglecting
    engineering considerations for full-cell configurations. This study investigates
    the effects of electrode composition and the balance in capacities between positive
    and negative electrodes (N/P ratio) on the performance of full-cell configurations,
    using Na3V2(PO4)3 (NVP) and hard carbon (HC) as representative electrode materials.
    Through a systematic analysis, we propose an optimal composition for NVP and HC
    electrodes, considering areal capacity and capacity retention during full-cell
    operations. Additionally, we underscore the importance of balancing the N/P ratio
    and the necessity of pre-sodiation techniques to achieve high-energy-density SIBs.
    Overall, this work sheds light on key factors influencing the performance of SIBs
    and provides insights into strategies for enhancing their energy density and operational
    efficiency.
