A new charging algorithm has been developed by researchers from Helmholtz-Zentrum Berlin and Humboldt University in Berlin, which could potentially double the life of lithium-ion batteries. This alternative solution aims to make lithium batteries more resilient, allowing them to retain a much higher energy capacity even after hundreds of discharge-recharge cycles.
The new algorithm proposes a change in the way the charger delivers current to the electrolyte materials inside the battery. By utilizing a pulsed current charging method, the researchers believe that the compact and robust Li-ion batteries of today could have an extended lifespan. This development is particularly significant as these batteries are increasingly being used in various devices and technologies, such as electric vehicles, where longer-lasting batteries would greatly benefit consumers.
The current charging algorithm employs constant current (CC) charging, which causes cracks in the electrode structures, leading to decreased battery performance over time. In contrast, the proposed pulsed current (PC) charging results in a thinner interface and reduced structural wear, enabling the battery to maintain a higher energy capacity for an extended period.
