|Lithium-ion batteries currently use only 30 percent of their maximum available storage capacity because premature failure of batteries can cause catastrophic results with huge financial as well as potentially fatal consequences. Manufacturing defects are a primary reason for the premature failure of batteries; however, there is not an effective way to test batteries until the components are assembled. Batteries are assembled by combining cathode and anode materials that have been coated onto thin metal films. Flaws in these coatings or the separator material can lead to premature failure of batteries, but currently, there is no method of testing for such flaws.
Researchers at Purdue University have developed an in-line technique for the manufacturing process to test for flaws in the coatings or metal films in batteries before they are assembled. This technology would allow for batteries with higher, more consistent quality components as well as a monitor to improve the manufacturing process of the cathode/anode materials. Batteries would have improved safety.
