A New Research Study to Manage the Problem of Battery Overcharge

Published By : 20 Oct 2014 | Published By : QYRESEARCH

According to research conducted at the Department of Chemistry, University of Kentucky, batteries can avoid getting overcharged. This as a result, will improve the safety of electronics ranging from mobile phones to aeroplanes.

The research group led by Susan Odom primarily focuses on synthesis, testing, and the design of organic compounds. These organic compounds can be incorporated in the electrolytes of batteries of lithium ions as a measure of improving the safety profiles. This research team is focusing on studying compounds which are known as redox shuttles.

Portable electronic gadgets like mobile phones and laptops make use of lithium-ion batteries which are the energy storage technology of choice. On a larger scale, these types of batteries have been incorporated in aeroplanes and electric vehicles, in the recent past.

The most crucial parameter for consumers and manufacturers is that of battery safety, mainly in applications where low battery performance and failure can prove to be fatal. 

For batteries connected in series, a major problem is that of being overcharged. In fact this problem can lead to explosions and fires in case there is a catastrophic failure. The redox shuttle compounds that are being examined at the University of Kentucky avoid this problem of overcharging that is caused due to the transmission of electrons between the electrodes of the batteries when excess current is applied to the fully charged batteries.

An undergraduate researcher of this research group has developed a new derivative of phenothiazine that aims at protecting the batteries from overcharging for several hours. The protection that this compound offered was almost four times more than its sole commercial competitor.
