This technology is a method to increase the electrolytic stability and performance of lithium-ion battery cathode interfaces by applying a nanoscale aluminum oxide coating.
Lithium-ion batteries are the most promising technologies today for energy storage, with wide applicability in mobile devices, portable electronics, and electric vehicle charging stations. However, high-density lithium-ion cells suffer from heating and have poor thermal stability within the battery cell architecture. There is a significant need to improve the thermal stability of lithium-ion cells without compromising the battery cell’s superior energy storage capabilities.
This technology is a method to improve the thermal stability and performance of high-energy density lithium-ion cells by the application of nanoscale aluminum oxide coatings. The coatings are applied between the cathode and the electrolytic substance to promote the flow of ions. Importantly, the coating can be applied to NMC cathodes, which are one of the most successful high-density Li-ion systems. This technology has been shown to increase the cycling lifetimes of lithium batteries without compromising battery performance, thereby expanding the range of applications for battery use.
This technology has been validated with a prototype.
