China energy storage net news: according to foreign media reports, the U.S. army research laboratory at the university of Maryland and the United States for the first time researchers developed to salt solution with water as the electrolyte, and voltage to laptop computers and other home appliances using standard 4.0 v lithium ion battery, at the same time, there are some commercial risk of fire and explosion of non-aqueous lithium batteries.
The study is based on a 2015 study published in the American journal science.
The study developed a similar 3.0-volt electrolyte battery, but failed to achieve a higher voltage due to the so-called "negative challenge".
A negative challenge is a battery that is made from graphite or lithium metal and is decomposed by a water electrolyte.
In order to solve this problem, to realize the voltage from 3 v to 4 v span, research papers, the authors Yang Chongyin assistant professor at the university of Maryland at college park, we design a can apply gel polymer electrolyte on graphite or lithium anode coating.
The new batteries that add the gel coating improve the safety of the standard non-water lithium battery, which increases the energy density compared to other lithium-ion batteries.
This battery is unique in that even interface layer damage (such as battery outer damage), it has to do with the positive reaction of lithium or lithium fossil ink is also very slow, can prevent the metal lead to fire or explosion after direct contact with the electrolyte.
