Empa Prospects or Produces Economical Lithium Batteries

Tip: According to foreign media reports, Ruben-Simon KU hnel and David Reber, two researchers from the Department of Energy Conversion Materials of the Swiss National Federal Laboratory, have developed a new scheme, in which sodium bis (fluorosulfonyl) imide is used. The salt is soluble in water, and 7 grams of sodium FSI and 1 gram of water can be mixed into a transparent solution. Researchers found that the electrochemical stability of the salt solution was as high as 2.6V, more than twice the value of other aqueous electrolytes. For research and development of affordable and safe cores, its findings may be the key, as detailed in the text.

According to foreign media reports, the Swiss national laboratory (Empa) energy conversion materials (Materials for Energy Conversion department) of two researchers Ruben – Simon Kuhnel  David Reber developed with new solutions, aims to solve the following problems: ensure that contain electrolyte salts for liquid form, at the same time ensure it reached high levels, and does not contain "(excess)" of excess water.

Two researchers in the experiment adopted double (sulfonyl fluoride) sodium imine [sodiumbis (fluorosulfonyl) imide, hereinafter referred to as sodium FSI 】.The salt can be dissolved in water, 7 grams of sodium FSI with 1 gram of water to a transparent solution. In the liquid inside, all the water molecules around within the hydrate positively charged sodium ions (positively charged sodium cations) around, almost no water molecules in free state to.

The researchers found that the electrochemical stability of the salt solution is as high as 2.6 V, is other aqueous electrolyte (aqueous electrolytes) value more than twice as many. For the research and development in terms of price is affordable and safe batteries, the study found that may be the key. The material price is not expensive, this is because compared with the conventional Lithium ion batteries, sodium FSI batteries is safer, more convenient also.

The system has had a series of pressure loop in the laboratory test. However, the researchers to separate test the anode and the cathode of the battery. In the future, will test the whole piece The lithium battery, the future will also charge and discharge test.
