Advances in materials for all‐climate sodium‐ion batteries

Abstract

Sodium‐ion batteries (SIBs) have attracted much interest for medium‐ to large‐scale energy storage applications owing to the high abundance and low cost of sodium reserves. However, a principal concern for the wide deployment of stationary SIBs is their temperature tolerance. Extreme temperatures can deteriorate the performance and safety of SIBs by causing very sluggish Na‐transfer kinetics, dendrites formation, and severe interfacial reactions. The development of all‐climate SIBs depends on the fundamental understanding of the chemical reactions at different temperatures and advances of all the key components, especially the electrolyte and the electrode materials. Herein, we start from briefing the key challenges in developing all‐climate SIBs, then examining the latest achievements in confronting the challenges. The insights presented in this review are believed to guide and inspire further research interest in designing all‐climate SIBs that will hopefully serve as a low‐cost, high‐performing, and reliable stationary energy storage solution.

Magnetic Properties and Environmental Temperature Effects on Battery Performance of Na0.67Mn0.5Fe0.5O2

“…We attribute such a high initial capacity at 40 and 50 °C to the temperature dependence of the chemical reaction and diffusion rates. [ 28 ] However, capacity retention capabilities are very weak as the battery loses ≈85% of its initial capacity by the 20th cycle under a 50 °C temperature environment. In contrast, the measurements at 10 and 20 °C show better capacity retention properties than the measurements at 30, 40, and 50 °C despite their lower initial capacities.…”

“…9,98 More importantly, the need for all-climate SIBs has increased in recent times. 99,100 From the technical point of view, apart from the ambient operating conditions, practical SIBs will operate under harsh conditions, too. More importantly, the power capability of a battery at low temperatures is a key factor in defining the performance of a battery in practical applications such as EVs and EBs.…”
