10 Years Development of Potassium‐Ion Batteries

Advanced Materials, EarlyView.
Significant progress is made in PIBs over the past decade, but the improvements based on half‐cell testing, low mass loading, and low energy density are insufficient for practical applications. This review summarizes the challenges and strategies for PIBs, highlights the importance of further research focusing on full cells, and provides an analysis of

Two‐Stage Bipolaron Formation in Molecularly Doped Conjugated Polymers

Advanced Materials, EarlyView.
This work investigates bipolaron formation in 2,3,5,6‐tetrafluoro‐7,7,8,8‐tetracyanoquinodimethane (F4TCNQ)‐doped conjugated polymer P(g32T‐T) films with glycol sidechains at two stages of both low and high doping levels. At the early stage, bipolarons mainly form from double doping, enhancing structural ordering, and carrier transport.
