Unexpected errors should use ERROR or FATAL log messages because they indicate a real problem. At best, they indicate an incorrect assumption. At worst, there’s a serious bug somewhere.
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。

董哲说，五代十国时期的不少史料，对人物的记录虽是简短着墨，却留下其人生的高光。《太平年》以点带面，让两百三十多号人物在剧中纷纭出场。
But e-bikes containing lithium-ion batteries are a newer challenge. "When a battery fails, it doesn't necessarily ignite, it will often produce some off-gases," says Stephen Welch, senior lecturer at the University of Edinburgh's Fire Research Centre. "Those off-gases are toxic and flammable. If they accumulate, you can have an explosion risk."
