Lithium-organic batteries feature transition-metal-free cathode, resource sustainability and low cost, showing great potential to be substitutes for lithium-ion batteries that greatly depend on scarce natural resources. However, lithium-organic batteries are plagued by the shuttle effect and unstable Li metal anodes, especially under extreme operating conditions. High-concentration or localized high-concentration electrolytes may mitigate these problems, but at the expense of high-cost and environmental concerns. Herein, we propose a standard-concentration electrolyte that shows excellent compatibility with both organic active materials (shuttle-effect-free) and Li metal anodes (Coulombic efficiency ∼ 99.52%) by weakening the solvent polarity. It demonstrates that the introduction of the nonpolar n-heptane can simultaneously inhibit the dissolution of perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA) and restrain side reactions between electrolyte solvents and Li metal, as well as weaken the affinity between solvents and Li⁺. The PTCDA|Li batteries retain 98.2% capacity after 200 cycles with an average Coulombic efficiency of 99.97%, and also show high cycling stability from −40 to +60 °C. With the replacement of traditional electrolyte by our electrolyte, the energy density of PTCDA|Li pouch-cells increases by 13.9% under identical conditions. Furthermore, our electrolyte can be extended to other (Li-sulfur, Li-FeS) batteries encountering the dilemma of the shuttle effect and unstable Li anodes.

锂有机电池具有无过渡金属正极、资源可持续、成本低等特点，显示出替代严重依赖稀缺自然资源的锂离子电池的巨大潜力。然而，锂有机电池受到穿梭效应和锂金属负极不稳定的困扰，尤其是在极端操作条件下。高浓度或局部高浓度电解质可以缓解这些问题，但代价是高成本和环境问题。在此，我们提出了一种标准浓度的电解质，通过削弱溶剂极性，它与有机活性材料（无穿梭效应）和锂金属负极（库仑效率～99.52%）均表现出良好的相容性。⁺。PTCDA|Li 电池在 200 次循环后保持 98.2% 的容量，平均库仑效率为 99.97%，并且在 -40 至 +60 °C 范围内显示出高循环稳定性。用我们的电解液替代传统电解液后，PTCDA|Li 软包电池的能量密度在相同条件下提高了 13.9%。此外，我们的电解质可以扩展到遇到穿梭效应和锂负极不稳定的其他（锂硫、锂铁硫）电池。
