“…9,10 The model stated that theoretically ideal voltage is related to the reaction between desired phases in the thermodynamic point of view. [9][10][11][12] Deviation of the voltage from its ideal value is related to extending of undesired (bipolarizing) phases. [9][10][11][12] The undesired phases would be generated due to concentration gradient regions at interfaces of the desired phases.…”

This paper proposes a mathematic relationship between obtained capacity and the corresponding current rate for the Li-S and Na-S conversion batteries.Using experimental data on different conditions of the Li/Na-S batteries, taken from literature, it is established that the inverse value of obtained capacity is changing linearly with respect to square root of the corresponding applied current rate. The theoretical-based relationship has been established for the Li-ion and Na-ion batteries. Therefore, this paper proposes similar behavior for the conversion and intercalation batteries. The proposed relationship and its beyond approach proffer estimations of: alteration of capacity by rate, optimal cathode mass, corresponding reaction components, and fraction of (in)active particles. Also, they offer a quantitative criterion for performance and ratecapability, the capability to justify observed phenomena, and also qualification of the powder, preparation, and assembling of the cell.

Voltage Hysteresis in Transition Metal Oxide Cathodes for Li/Na‐Ion Batteries

essential for the commercial application of Li/Na-ion batteries. The investigated cathode materials mainly include oxides, polyanion compounds, Prussian blue analogues, and organic salts. Among them, layered transition metal oxides contained in oxides are promising candidates due to their suitable operational potentials, 2D ions diffusion channels, and simple synthesis. Meanwhile, it was generally believed that to achieve a fast ions diffusion, the atomic configuration in the crystal structure of layered cathode materials must be well ordered. [7,8] However, this stereotype is now being reconsidered with the discovery of the percolation theory about 3D ions diffusion in a disordered rock-salt (DRX) structure. [9,10] This percolation occurs when Li-ions hop from one octahedral site to another through an intermediate tetrahedral site, where the Liions in the tetrahedral sites are identified as an active Li for the hopping. [11] In this regard, various new types of Li-rich DRX cathode materials with promising capacities (>250 mAh g −1 ) have been discovered. [12][13][14][15][16][17][18][19] Given their unique advantages, these oxide materials have attracted extensive attention from researchers worldwide.Although demonstrating a high capacity, application-wise, these oxide materials also exhibit voltage hysteresis and significant loss of energy density, since the voltage associated with this redox process on charge cannot be recovered on discharge, which represents a key challenge that inhibits exploiting the full potential of these materials. This voltage hysteresis persists throughout the electrochemical cycling, resulting in a continuous decrease of the average discharge voltage. Therefore, the understanding of voltage hysteresis is particularly important because it not only minimizes energy density and drastically reduces energy efficiency but also hinders further development and commercialization of Li/Na-ion batteries. When voltage hysteresis was discovered in LiFePO 4 materials in the early years, experimental limitations and the lack of a theoretical framework prevented researchers from drawing concrete conclusions about the phenomenon. With the development of increasingly sophisticated analytical techniques for studying voltage hysteresis, reassessing the understanding of the origin of voltage hysteresis can now be done from a mechanical perspective and even reveal new discoveries that were previously unavailable due to experimental limitations.

Oxygen redox in layered oxide cathodes for Na‐ion batteries is considered a promising approach for improving the energy density. However, oxygen‐redox‐based cathodes suffer from sluggish kinetics and undesirable structural change during charge/discharge, leading to poor electrochemical performances. Herein, introducing vacancies (□) in the transition metal layers enables the enhanced oxygen redox‐based electrochemical performances in the P3‐type Mn‐based layered oxide cathode is demonstrated. The vacancies can play a role of the local distortion buffers, resulting in the enhanced oxygen redox kinetics and the suppressed structural deformation such as P3‐O3(II) phase transition. The oxygen‐redox‐based P3‐type Na0.56[Ni0.1Mn0.81□0.09]O2 exhibits the large discharge capacity of ≈140.95 mAh g−1 at 26 mA g−1 with a high average discharge voltage of ≈3.54 V (vs Na+/Na). Even at 650 mA g−1, its discharge capacity and average operation voltages delivered ≈122.06 mAh g−1 and ≈3.22 V, respectively. Especially, the small gap of average discharge voltage indicates both improves power‐capability and enhanced kinetics of oxygen redox in P3‐type Na0.56[Ni0.1Mn0.81□0.09]O2. Moreover, the vacancy buffer in the transition metal layers results in the stable cycle‐performance of P3‐type Na0.56[Ni0.1Mn0.81□0.09]O2 with the capacity retention of ≈80.80% for 100 cycles, due to the suppressed P3‐O3(II) phase transition.
