According to the "Forbes" website, the characteristics of lithium-ion batteries are small, and the amount of electricity is large, long use. Lithium-ion batteries have a variety of forms, which are widely used in medical devices including mobile phones, notebooks, cameras, and clocks, and have even and aerospace equipment. The University of Cambridge said in October that they have developed a new battery lithium-oxygen or air battery, and the charging of 2000 efficiency can still reach 90%.

The researchers said that this battery should be implemented for 10 years. "Forbes" said that last week, the University of Maryland and the US Army Research Laboratory said they have developed a "water-in-salt) lithium-ion battery, which has time and efficiency. To achieve a considerable level of ordinary lithium-ion batteries, it does not use chemicals of toxic and polluting the environment, such as sulfuric acid, lead and cadmium.

Battery that produces relatively low production hazards will have a long-term impact on environment and consumers. In April 2015, Tesla announced the newly set up a business department Teslanery, providing household battery solutions to consumers and companies. This triggered a fierce discussion of the rapidly rising energy storage market.

"Forbes" said that in view of Tesla household battery solutions, the order quantity exceeds 100,000, non-toxicated aqueous lithium-ion batteries may be a good product. Such new batteries are especially applicable to energy demand reaches kW-scale applications, such as electric vehicles, etc., the maximum use of electric vehicles may lie extremely attach importance to battery safety and toxic applications, for example, for airplanes, navy ships, Safety and non-flammable batteries of spaceship.

The researchers said that the use of water-based high concentration of lithium salt electrolyte is a breakthrough, which changes the chemical process of the battery, manufacturing a thin layer of protective film on the anode. Protecting the film's stability of the battery, and the same performance as the existing lithium ion battery is critical. According to the US Army Research Laboratory Energy and the Power Department Edwardshaffer, this finding can improve the battery safety.

He said that the application of new batteries includes equipment carrying and worn by soldiers, and more secure, smaller energy storage devices such as limited spaces. "Forbes" pointed out that the research team leading Wang Chunsheng (CHUNSHENGWANG, translation), Associate Professor of the University of Maryland, said that due to voltage / electricity, this technology represents a major progress in the history of water-based battery development. Their research results were published in "Science" magazine.
