Over the past decades, significant advances have been made in lithium‐ion batteries. However, further requirement on the electrochemical performance is still a powerful motivator to improve battery technology. The solid electrolyte interphase (SEI) is considered as a key component on negative electrode, having been proven to be crucial for the performance, even in safety of batteries. Although numerous...
The limited cyclability of high‐specific‐energy layered transition metal oxide (LiTMO2) cathode materials poses a significant challenge to the industrialization of batteries incorporating these materials. This limitation can be attributed to various factors, with the intrinsic behavior of the crystal structure during the cycle process being a key contributor. These factors include phase transition...
Polyurethane (PU) is a traditional chemical known for its chemical stability and mechanical performance. Inspired by the similarity between the formation and breakage of chemical coordination bonds and the energy storage and release of muscle fibers, muscle‐like electrostatically spun fibers with acid‐responsive energy storage and release were prepared by introducing bio‐inspired elastic energy storage...
LiMn1‐yFeyPO4 (LMFP) is a significant and cost‐effective cathode material for Li‐ion batteries, with a higher working voltage than LiFePO4 (LFP) and improved safety features compared to layered oxide cathodes. However, its commercial application faces challenges due to a need for a synthesis process to overcome the low Li‐ion diffusion kinetics and complex phase transitions. Herein, a solid‐state...

In article number 2309629, Yingqiang Wu, Li Wang, Fengli Bei, Xiangming He, and co‐workers present a LiMnxFe1‐xPO4 solid‐state synthesis method using LiFePO4 and nano LiMn0.7Fe0.3PO4 that coexist at room temperature, happen at low sintered temperatures (300–600 °C) and complete at high sintered temperatures (700∼800 °C). Following sintering at high temperatures, LiMnxFe1‐xPO4...
