科学家们研发新型水基防爆防火锂电池

【摘要】:正根据国外媒体报道,美国马里兰大学的一个华人科学家团队最近研制出了一种基于水基电解液的新型锂离子电池,该电池不仅在电压上首次达到了笔记本电脑等家用电子产品所需要的标准,同时还能避免着火和爆炸的危险。在现有的电子产品中,锂离子电池都使用了非水性电解液。电子设备在工作时电池电压必须要满足4V的标准,但在这个电压之下,水很容易就会被电解,所以锂电池通常所使用有机溶剂作为电解液,但这些电解液具有易燃易爆性,存在着极大的安全隐患。据了解,该研究团队曾经在2015年时就研发了一种水电解液电池,但由于电压最高只有3V,且电极性能会受到水溶液的影
[Abstract]:According to foreign media reports, a team of Chinese scientists at the University of Maryland recently developed a new type of lithium ion battery based on aqueous electrolyte. The battery not only meets the voltage standards required for household electronics such as laptops for the first time, but also avoids the risk of fire and explosion. In existing electronic products, lithium ion batteries use non-water electrolyte. The battery voltage must meet the 4V standard when the electronic equipment is working, but at this voltage, water is easily electrolyzed, so lithium batteries usually use organic solvents as electrolytes, but these electrolytes are flammable and explosive. There are great hidden dangers to safety. It is understood that the research team developed a water electrolyte battery in 2015, but because the highest voltage is only 3 V, and the electrode performance will be affected by the aqueous solution.
