According to foreign media reports, the researchers of the University of Maryland and the US Army Research Experiments first developed the use of aqueous salt solution as an electrolyte, and the voltage reached the use of standard 4.0 volts using standard 4.0 volts, at the same time Some commercial non-aqueous lithium ion batteries in fire and explosion risk.

It is reported that this study is based on a study of the US "Science" Weekly 2015. That study has developed a similar 3.0 volts of water electrolyte battery, but it failed to achieve higher voltages due to so-called "negative challenges".

The negative challenge refers to the battery made of graphite or metal lithium will be decomposed by hydrophilic. In order to solve this problem, the voltage from 3 volts to 4 volts, the first author of the research papers, Yang Chongyin (tone), an assistant researcher in Maryland, designed a gel polymer electrolyte coating that can be applied to graphite or lithium positive electrodes. The new battery added to the gel coating improves safety compared to standard non-aqueous lithium ion batteries, which improves energy density than other lithium ion batteries.

The uniqueness of this battery is that even if the interface layer is damaged (such as damage to the outer layer), it is also very slow to react with lithium or lithium graphite positive electrode, which prevents metal from direct contact with the electrolytic solution, causing fire or explosion.
