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。

Measuring the orbital shift of a 780-meter-wide primary asteroid and its moonlet from millions of miles away isn’t trivial. When DART slammed into Dimorphos, it didn't knock the binary system wildly off its trajectory around the Sun. The change in the system's heliocentric trajectory was expected to be small, a minuscule nudge that would become apparent only after months or years of continuous observation. By analyzing enough painstakingly gathered data, a global team of researchers led by Rahil Makadia at the University of Illinois Urbana-Champaign has now determined the consequences of the DART impact.
