Ultimately, rigorous studies on battery lifespan coupled with the adoption of holistic strategies will markedly advance the reliability and stability of battery technologies, forming a robust groundwork for the progression of the energy storage sector in the future. 3. Necessity and data source of early-stage prediction of battery life
Generally, a RPT (Resistance Pulse Test) is performed regularly during a life test of a cell. Even though the absolute life time of a cell cycled at different load cycles is of great interest; it can be argued that the evolution of capacity, impedance and other cell properties over the battery life provides profoundly more important information.
Abstract: The cycle life test provides crucial support for using and maintenance of lithium-ion batteries. The mainstream way to obtain the battery life is uninterrupted charge-discharge testing, which usually takes one year or even longer and hinders the industry development. How to rapidly assess the life of new battery is a challenging task.
In the manufacturing phase, the life of the LIB is evaluated by the charge-discharge cycle in the formation stage, which can streamline factory testing, expedite the quality control process, and ultimately reduce manufacturing costs by providing an early indication of battery life expectancy.
Accelerated test methods are interesting for use by both cell manufacturers and application developers to estimate battery lifetime. However, the combination of a narrow temperature range and non-linear ageing reduces the possibilities to find an efficient and reliable method for significantly reducing the time to test battery lifetime.
