New energy storage technology effectively extends the life of lithium-ion batteries

Lithium-ion batteries are ubiquitous in electronics. It is one of the most widely used rechargeable batteries in portable electronic devices, with high energy density, no memory effect, and will not lose too much battery power during use. In addition to consumer electronics, lithium-ion batteries are widely used in specialty, electric vehicles, and specialty aerospace.

Recently, researchers at Arizona State University (ASU) have developed a new energy storage technology that can greatly extend the life of batteries.

Dan Butri, a professor in the departments of chemistry and biochemistry at Arizona State University, is testing battery samples with undergraduate student Tiran Watkins

The team was led by Dan Butri, a professor in Arizona State University's Department of Chemistry and Biochemistry. Olson is an undergraduate seminar member in Butry's team, working in the field of ionic liquids. Olson's work on the workshop ended with his internship at Boulder Electronics, where he and Watkins are partners at Boulder and Arizona State University.(Lithium - Ion Battery Equipment)

The research, published in the journal Nature Communications, involved data from Arizona State University, University of Boulder, San Diego National Laboratory, Bouldereonic ) and scientists at Seoul University in South Korea.

Extend battery life

Ionic liquids have special physical and chemical properties at room temperature, such as high thermal stability, wide potential window, and low vapor pressure. Therefore, ionic liquids have attracted the interest of many researchers in recent years.

We used a device called a quartz microbalance, which measures the mass of the battery as it charges and discharges on the film on the outside of the battery. Buttry said. One of the keys to the success of a lithium-ion battery is declaring that you can maintain the thin film of the battery's electrodes, which will greatly extend the life of the battery. This research improves the preparation of such films, enabling lithium-ion batteries with superior performance than today's lithium-ion batteries.

But Terry went on to add: We hope that this new battery formulation will be successful.

This role is only part of what Buttry Labs has accomplished. Bootley's lab was previously funded by the PowerAdvanceResearchProgram and is now funded by the Army Research Office.

Measuring the above mass change is not easy because it is not easy to weigh the composite membrane with a quartz microbalance. Watkins said. In addition to this, there is little research on how quartz microbalances measure the quality of the apparent films of active materials, which means that a deposition method tailored to this situation is necessary. Fortunately, we've been able to make this very useful film that you might see on the market someday.

This effect provides a new scientific basis for the study of interface stability between silicon-based materials and ionic solutions.

By placing a high-performance silicon electrode in a solution containing a new difluorosulfimide ion electrolyte at room temperature, researchers have emerged a lithium-ion battery with high energy density and long life that can last for more than 500 charge/discharge cycles 75% capacity, near perfect current efficiency.

Buttry said: "This study shows that there is still a lot of room for research in energy storage technologies and that new technological innovations will emerge in the near future. It's important to think clearly about where you're going to store your energy, grid storage is still battery storage for electric vehicles, for example.

According to Watkins, there are many reasons why modern society wants higher energy density batteries.

Watkins said: "Silicon electrodes were once considered the most likely material to replace carbon electrodes, because silicon electrodes have nearly 10 times higher energy density than cathodes. This exciting collaboration brings us one step closer to developing high-energy-density batteries with silicon electrodes.
