On February 18, Professor Huang Fei's team from the State Key Laboratory of Luminescent Materials and Devices, South China University of Technology (SCUT), in collaboration with Professor Xu Yunhua’s team from Tianjin University and other partners, successfully fabricated a high-mass-loading organic electrode based on the n-type conducting polymer poly(benzodifurandione) PBFDO and developed an organic pouch cell with an energy density exceeding 250 Wh/kg. 

The battery demonstrates robust cycling stability and can operate over a wide temperature range from -70 ℃ to 80 ℃, while also offering excellent flexibility and safety. The findings were published in Nature under the title “Practical lithium-organic batteries enabled by an n-type conducting polymer”.

Electrodes based on PBFDO exhibit high electron conductivity, high specific capacity, and a high lithium-ion diffusion coefficient, effectively overcoming traditional organic electrode limitations of poor conductivity and the difficulty of fabricating high-mass-loading electrodes. 

This achievement validates the feasibility of organic electrode materials in practical energy storage systems and marks a critical step in advancing organic battery technology from laboratory research toward industrial application.
