As the demand for sustainable and low-cost energy storage grows, sodium-ion batteries (SIBs) have emerged as a promising alternative to lithium-ion systems. However, their performance under extreme temperatures remains a major hurdle. Now, researchers from China University of Mining and Technology, led by Professor Danyang Zhao and Professor Yanwei Sui, have developed a breakthrough anode material—quantum-sized FeS₂ anchored on 3D MXene—that delivers exceptional sodium storage performance from −35 °C to 65 °C.
