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。,这一点在谷歌浏览器下载中也有详细论述
The appetite for stricter typing continues to grow, and we’ve found that most new projects want strict mode enabled.
