Scientists Investigate New Materials for Li-Ion Batteries of Miniature Sensors



Scientist of Peter the Great St. Petersburg Polytechnic University (SPbPU) are establishing new materials for solid-state thin-film Li-ion batteries for micro and nanodevices. The very first phase of the job was effectively finished at the lab “Functional Materials” of the Institute of Metallurgy, Mechanical Engineering, and Transfer SPbPU. The job is supported by the Russian Science Structure (RScF).

Part of the outcomes gotten at the very first phase of the job was released in the short article “Atomic Layer Deposition of NiO to Produce Active Material for Thin-Film Lithium-Ion Batteries” in the journal Coatings, MDPI.

The authors recommended utilizing a new set of reagents to get the electrode materials based upon nickel oxide. Scientist studied the basic procedures occurring throughout the charge and discharge procedures of thin-film product.

It must be kept in mind that the lithium-ion batteries are utilized not just in phones and laptop computers however likewise in the entire class of micro and nanodevices such as cordless sensors, pacemakers and etc. These gadgets, typically, run utilizing thin-film present sources. The smaller sized the gadget, the thinner the source of power is needed. For that reason, the materials must have enhanced electrochemical qualities to run longer without surcharge.

“In the frames of the RScF project, we obtained an electrode material based on nickel oxide by atomic layer deposition (ALD) using new processes. We demonstrated its possible application in Li-ion batteries by studying its electrochemical features. In the future, we are planning to improve the materials of electrodes for thin-film batteries. It will bring us closer to a prototype of a solid-state thin-film Li-ion battery produced by ALD. I suppose that the positive results undoubtedly will be interesting for commercial application”, states Maxim Maximov, leading scientist of the lab “Functional Materials” of the Institute of Metallurgy, Mechanical Engineering and Transportation SPbPU.
