π-Extended Benzo[b]phenazine-Based Polymer Cathode Materials for High-Voltage and Stable Organic Batteries

Abstract: Organic materials are considered potential electrode materials for lithium-ion batteries (LIBs) due to their high theoretical capacity, abundant source, low cost, structure diversity, and environmental friendliness. Herein, we further enhance the discharge voltage and stability by extending the conjugated structure while constructing an active unit based on 5,12-dihydrobenzo[b]phenazine (BPZ) and the corresponding polymer p-DPBPZ. p-DPBPZ|Li cells exhibit excellent integral performances with discharge voltages… Show more

“…The phenazine moiety exhibits a higher theoretical capacity (255 mAh g –1 vs. Li/Li + ) compared to the triphenylamine molecule. The molecular structure of this compound incorporates two nitrogen atoms, providing dual discharge platforms with moderate and flat voltage profiles (3.9–3.6 V and 3.3–3.0 V vs. Li/Li + ). , Nevertheless, the phenazine moiety presents challenges in electron release for direct utilization. The targeted design and synthesis of molecules for the creation of high-capacity p-type or bipolar-type materials represent a highly effective approach, while it can circumvent the challenges associated with dissolution and low conductivity …”
