Title: Krystal J. Lee and Advances in Lithium Battery Technology.
Introduction
Krystal J. Lee is an inventor associated with Albany, New York, and research on lithium battery materials. Her work includes inventions involving vanadyl phosphate cathodes and lithium metal batteries. Lee is associated with The State University of New York and Pure Lithium Corporation. Her patent portfolio includes 3 patents.
Latest Patents
Lee’s latest patent work includes “Rechargeable Lithium Battery with an Improved ε-VOPO Cathode, and Applications Thereof.” The invention describes a lithium battery using the epsilon polymorph of vanadyl phosphate, ε-VOPO₄, as its cathode. The material is made from solvothermally synthesized HVOPO₄ and is designed to reversibly intercalate two lithium ions, reaching its theoretical capacity with a reported coulombic efficiency of 98%.
The cathode material’s stable three-dimensional tunnel structure allows it to extract two lithium ions per vanadium ion. The patent describes a theoretical capacity of 305 mAh/g, with charge and discharge plateaus near 4.0 V and 2.5 V. It also discusses modifying ε-VOPO₄ particles with niobium to improve cycling stability.
Another patent, “Lithium Metal Battery,” describes a battery with a negative electrode comprising substantially pure lithium metal and a positive electrode comprising ε-VOPO₄. The disclosure specifies lithium metal containing less than five parts per million of non-metallic elements by mass. It also describes the cathode’s lithium-ion intercalation, theoretical capacity, voltage plateaus, and potential niobium modification for improved cycling stability.
