Scientists from MSU have created a material for quick charging batteries
Researchers from the Moscow State University (MSU) have improved the material creating technology for Lithium iron phosphate battery (LiFePO4). The material allows the battery to be almost fully charged within minutes and has high reliability.
Scientists have found a way to change the substance properties that is used in the negative electrode of the battery. Now the industry is interested in the appearance of reliable batteries that can be quickly charged, the MSU press service told. Incidents with the ignition of lithium-ion batteries on board Boeing Dreamliner aircraft and the recall of Samsung mobile device batteries are demonstrative examples of the necessity to look for new technologies.
A group of researchers modified a substance with the formula LiFePO4, that is used in batteries since the early 2000s. Lithium iron phosphate batteries are durable and safe, but have a relatively low energy storage capacity. To change the substance properties, scientists used an «innovative synthesis — growing small crystals of a given orientation». The substance is synthesized from a solution with an organic solvent, the representative of the MSU chemical faculty explained.
Batteries using this material can be charged in half a minute-minute by 75-80%. Besides, batteries may be used in high power mode, which is important for electric cars, robots and unmanned aerial vehicles. Several companies are interested in the use of the material.
