Stable quasi-solid-state lithium-organic batteries (QSSLOBs) have received widespread attention due to their high energy density, nonflammability, and environmental friendliness. However, the undesirable interfacial compatibility between organic cathode polymer electrolytes (PEs) usually results in unsatisfactory performance. Herein, two types of optimized PEs (gel-based PEs, GPEs, eutectic-based EPEs) are fabricated matched with small-molecule quinone (2,3,5,6-tetraaminobenzoquinone, TABQ, 1,4-benzoquinone, BQ) materials. Benefiting from heteroatom groups (−NH2) enhancing cathode–electrolyte interface compatibility, TABQ shows higher electrochemical performance (310.4 mAh g–1 at 50 mA for GPE system 312.6 EPE system) than its analogue BQ. Additionally, theoretical calculations detailed characterizations confirm positive effect enhanced on properties also reveal charge storage mechanism TABQ. These show that this strategy constructing could create a new chapter preparation high-performance QSSLOBs.
