“…S7 shows the discharge voltagecapacity curve of Fe/Li 2 O in a selected low-voltage range during electrochemical measurements. Based on the fitted values of n in the vicinity of Small Q (n ≈ 3), we could confirm the presence of an effective metal-nonmetal interface within the 0.01-1.3 V range 54,56 . Subsequently, the value of F(E,Q) was obtained according to the formula FðE,QÞ = E + n k B T e lnQ.…”

Lithium‐ion batteries with fast-charging/discharging properties are urgently needed for the mass adoption of electric vehicles. Here, we show that fast charging/discharging, long-term stable and high energy charge-storage properties can be realized in an artificial electrode made from a mixed electronic/ionic conductor material (Fe/LixM, where M = O, F, S, N) enabled by a space charge principle. Particularly, the Fe/Li2O electrode is able to be charged/discharged to 126 mAh g−1 in 6 s at a high current density of up to 50 A g−1, and it also shows stable cycling performance for 30,000 cycles at a current density of 10 A g−1, with a mass-loading of ~2.5 mg cm−2 of the electrode materials. This study demonstrates the critical role of the space charge storage mechanism in advancing electrochemical energy storage and provides an unconventional perspective for designing high-performance anode materials for lithium-ion batteries.

Lithium‐based batteries (LBBs) are highly researched and recognized as a mature electrochemical energy storage (EES) system in recent years. However, their stability and effectiveness are primarily confined to room temperature conditions. At temperatures significantly below 0 °C or above 60 °C, LBBs experience substantial performance degradation. Under such challenging extreme contexts, sodium‐ion batteries (SIBs) emerge as a promising complementary technology, distinguished by their fast dynamics at low temperature region and superior safety under elevated temperatures. Notably, developing SIBs suitable for wide‐temperature usage still presents significant challenges, particularly for specific applications such as electric vehicles, renewable energy storage, and deep‐space/polar explorations, which requires a thorough understanding of how SIBs perform under different temperature conditions. By reviewing the development of wide‐temperature SIBs, we systematically and comprehensively analyze the influence of temperature on the parameters related to battery performance, such as reaction constant, charge transfer resistance, etc. The review emphasizes challenges encountered by SIBs in both low and high temperatures while exploring recent advancements in SIB materials, specifically focusing on strategies to enhance battery performance across diverse temperature ranges. Overall, insights gained from these studies will drive the development of SIBs that can handle the challenges posed by diverse and harsh climates.This article is protected by copyright.
