Lithium batteries have become indispensable power sources across a spectrum of modern technologies due to their unparalleled energy density and commendably low discharge rates. From simple devices such as smartphones to the burgeoning fields of electric cars, drones, satellites, and portable medical devices, the proliferation of lithium-ion batteries underscores the central role that they play in shaping today’s lifestyles and industries. But amid the fervor surrounding their widespread adoption, optimizing lithium-ion batteries requires a nuanced understanding of the behavior of the individual cells that make up these powerhouses. This imperative requires not only the accurate modeling of these cells, but also the precise identification of their relevant parameters. By subjecting these cells to controlled discharge scenarios, we have uncovered vital information regarding factors such as capacity, internal resistance, and voltage profiles at different temperatures.
