For the first time, two novel air-sensitive Li-rich organic cathodes (m-TP4OLi and p-TP4OLi) are designed and reported. The structure-performance relationship for the two organic cathodes is comparatively studied. Using organic anode of lithium terephthalate (Li₂TP), the resulting Li₂TP II p-TP4OLi all-organic Li-ion batteries can deliver the peak discharge capacity of 330 mAh g⁻¹_cathode in 1–3.4 V, corresponding to the high energy density of ~574 Wh kg⁻¹_cathode using the median voltage of 1.74 V. Furthermore, the fabricated graphite II p-TP4OLi Li-ion batteries can show the peak discharge capacity of 305 mAh g⁻¹_cathode in 1.5–3.4 V with a high median voltage of 2.4 V, resulting in the peak energy density of ~732 Wh kg⁻¹_cathode (2.4 V × 305 mAh g⁻¹). Meanwhile, the graphite II p-TP4OLi Li-ion batteries exhibit impressive device stability over 20,000 cycles. To the best of our knowledge, the peak energy density of our p-TP4OLi is currently the world record among Li-rich organic cathodes in lab conditions, outperforms the energy density of inorganic LiFePO₄ (~476 Wh kg⁻¹), comparable with that of inorganic LiCoO₂ (~760 Wh kg^-1) under the same lab conditions.

首次设计并报道了两个新颖的对空气敏感的富锂有机阴极（m -TP4OLi和p -TP4OLi）。比较研究了两种有机阴极的结构性能关系。使用对苯二甲酸锂（Li ₂ TP）的有机阳极，所得的Li ₂ TP II p -TP4OLi全有机锂离子电池可在1–3.4 V的电压下提供330 mAh g ^-1_阴极的峰值放电容量，对应于使用1.74 V的中值电压可实现〜574 Wh kg ^-1_阴极的高能量密度。此外，制造的石墨II p-TP4OLi锂离子电池在1.5–3.4 V时可显示305 mAh g ^-1_阴极的峰值放电容量，且中值电压为2.4 V，因此峰值能量密度约为732 Wh kg ^-1_阴极（2.4 V） ×305 mAh g ^-1）。同时，石墨II p -TP4OLi锂离子电池在20,000次循环中显示出令人印象深刻的器件稳定性。据我们所知，目前在实验室条件下，p -TP4OLi的峰值能量密度在富锂有机阴极中创世界纪录，超过了无机LiFePO ₄的能量密度（约476 Wh kg ^-1），可与LiCoO ₂（〜760 Wh kg ^-1）在相同的实验室条件下。
