【Flexible Paper-Based Li-ion Batteries: A Review】

Here, recent research findings on flexible paper-based substrates in Lithium-Ion (Li-Ion) batteries to improve their applications in high energy and power requirements are reported. And various applications and challenges of flexible batteries in healthcare and various energy storage systems, considering practical implementation, are argued.

成长就像走夜路一样，既没有灯也没啥人，但正因为黎明很美，所以你要酷酷的走下去。

对别人生气1分钟，就失去了自己人生中60秒的快乐。

For every minute you are angry with someone, you lose 60 seconds of happiness in your life.
Growth is like walking at night, neither lights nor what people, but because the dawn is beautiful, so you have to cool down.

【#沿着高速看中国#：山西吕梁的“九曲黄河第一镇”】吕梁市临县的碛口古镇有着“九曲黄河第一镇”的美誉。碛口于清代乾隆年间兴起，此后200余年是中国北方著名的商贸重镇。碛口的李家山民居以窑洞为主，造型与风格都十分考究。著名画家吴冠中先生曾评价说，“这样的房子，走遍全世界都难以找到。”Qikou is a small but ancient township in north China's Shanxi Province. Known as the "first town of the Yellow River," history recognizes Qikou as a famed port location that gained prosperity during the Ming (1368-1644) and Qing (1644-1911) dynasties. In its heyday, about 500 wooden boats would moor along its docks. The Li Village in Qikou is worth a visit for its distinctive cave dwellings with characteristic buildings on the Loess Plateau. A famous Chinese painter Wu Guanzhong once said, "Travel around the world and you will find no such buildings elsewhere."
