A Guardian investigation with DeSmog reveals thousands of tonnes of fish are illegally turned into fishmeal and oil off the coast of Guinea-Bissau
2月18日，天津大学、华南理工大学等团队在《自然》（Nature）发表论文Practical lithium–organic batteries enabled by an n-type conducting polymer，报告他们研制出一种基于n型导电聚合物正极——聚苯并二呋喃二酮（PBFDO）——的实用化有机锂电池。该聚合物具有优异的混合离子-电子传输性能和低溶解性，可在-70℃至80℃的温度范围内高效工作。其实现了超高面载量聚合物正极（最高达206mg/cm²），面容量高达42mAh/cm²，且循环稳定性优异。研究团队还制备出实用化2.5Ah锂-有机软包电池，能量密度达到255 Wh/kg。，这一点在新收录的资料中也有详细论述
