He holds a total of 5 patents that showcase his contributions to the field of electrochemical systems and lithium-ion battery technology. His work has significantly advanced the understanding and performance of these technologies.
Latest Patents
One of his latest patents focuses on methods and algorithms of cyclic coulometry. This patent discusses systems, devices, and methods for diagnosing an electrochemical cell using cyclic coulometry. An exemplary battery diagnostic system includes a current generator that produces symmetric charge and discharge currents to excite an electrochemical cell. The cyclic coulometer evaluates the performance of the electrochemical cell by adjusting the charge or discharge time to maintain a monitored cell voltage at a specific setpoint. This adjustment is achieved by changing the timing of the current switch, which reverses the current direction. The cyclic coulometer measures various electrical parameters during the charge or discharge cycle and generates a performance metric based on these measurements.
Another significant patent involves lithium-ion batteries with improved abuse tolerance and performance. This innovation includes a cathode made from a lithium compound, enhanced with solid additives based on metal nitrides and/or borates. These solid additives improve the capacity retention of the lithium-ion battery and extend its lifetime. They also help reduce the internal resistance that typically increases as lithium-ion batteries age, stabilizing the lithium-ion chemistry at high cell potentials or temperatures.
