【摘要】：正根據(jù)國外媒體報(bào)道,美國馬里蘭大學(xué)的一個(gè)華人科學(xué)家團(tuán)隊(duì)最近研制出了一種基于水基電解液的新型鋰離子電池,該電池不僅在電壓上首次達(dá)到了筆記本電腦等家用電子產(chǎn)品所需要的標(biāo)準(zhǔn),同時(shí)還能避免著火和爆炸的危險(xiǎn)。在現(xiàn)有的電子產(chǎn)品中,鋰離子電池都使用了非水性電解液。電子設(shè)備在工作時(shí)電池電壓必須要滿足4V的標(biāo)準(zhǔn),但在這個(gè)電壓之下,水很容易就會被電解,所以鋰電池通常所使用有機(jī)溶劑作為電解液,但這些電解液具有易燃易爆性,存在著極大的安全隱患。據(jù)了解,該研究團(tuán)隊(duì)曾經(jīng)在2015年時(shí)就研發(fā)了一種水電解液電池,但由于電壓最高只有3V,且電極性能會受到水溶液的影
[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.
