Lithium-ion Batteries 10 Times More Durable

Researchers continue to strive to create a battery that has a longer power cycle of the commercial battery generally used by many people. This is considered important because the use of which already covers other fields. Not only for portable electronics, but also roam in the field of military, automotive, aerospace and probably will roam on other fields.

The study results were published in the journal Nature Communications, which scientists describe the room-temperature ionic liquids have attracted much attention in recent years because of its physicochemical properties were exceptional, including high temperature stability, wide electrochemical space and low vapor pressure. This work provides new knowledge related to the stability of interfacial silicon-based materials that bring positive exposure to the electrochemical ionic liquids.

Lithium-ion battery research More Durable

Lithium-ion batteries have a high energy density, no memory effect, and will only lose a little energy when not in use. This is what inspired the researchers to do research. Scientists from Arizona State University exploring new energy storage technologies that can provide power cycle. The study was led by Prof. Dan Buttry of ASU, Jarred Olsen and Tylan Watkins, they examine ionic liquids.

According Buttry, they use a tool called a quartz crystal microbalance to measure mass changes very little in a thin film on the surface of the battery materials during charging and discharging. One key to the success of lithium battery materials that they developed a thin film that protects the surface of a battery electrode, which can prolong battery life. This study documents the development only on the film in a new type of battery formulation that has many more interesting features than existing commercial lithium batteries. Scientists hope of the future that this new formulation will give way to commercial use. It is not a measurement that is taken lightly because the film composite, which means the film of the active ingredient in the polymer matrix is often difficult to use on a quartz crystal microbalance. Most not all, studies of this kind of quartz crystal microbalance using a very thin film of the active ingredient alone, in other words a special deposition method must be used. The most interesting, that the scientists were able to perform measurements on many film, something that may seem realistic in commercial batteries.

By combining high-performance silicon electrode design with room-temperature ionic liquid electrolytes containing anion-fluorosulfonylamide new bus, scientists prove the lithium-ion cells are very dense energy to power live longer. This technique retains a capacity of more than 75 percent in excess of 500 cycles of power usage and charging with almost perfect efficiency, no wasted electrons.

This study states that energy storage technologies still have a great chance to be explored, along with new technologies that change comes quickly. It really is important when considering a case where the storage is important, such as electronic media storage and electric vehicles. The most common, many reasons why modern society demands more power in the energy-intensive. In some future time, the silicon anodes have been proposed as a replacement anode made ​​of carbon found with the use of the device, as it could potentially provide the energy density nearly 10 times that of modern anode. This technique can bring the energy development one step closer to realizing more energy dense batteries with anodes of silicon.
