Fast charging is a key differentiator for OEMs, but avoiding lithium plating remains a fundamental challenge in Li-ion battery system design. It can lead to capacity loss and severe safety risks. Our latest whitepaper explains how anode potential modeling can prevent lithium plating risks.
Fast charging is critical for EV adoption, but it increases the risk of lithium plating. Lithium plating occurs when lithium deposits as metal on the anode, rather than properly intercalating into the electrode material. This can lead to capacity loss, performance degradation, and serious safety risks such as internal short circuits and thermal runaway.
One of the biggest challenges in preventing lithium plating is that it cannot be directly measured in a full-cell setup. Instead, battery engineers rely on indirect indicators and extensive experimental testing, making it difficult to accurately define safe charging protocols.
At TWAICE, we’ve tackled this challenge with our latest Anode Potential Simulation Model. It enables fast and reliable lithium plating prediction to optimize charging strategies.
We’ve explored this topic in depth in our latest whitepaper, where we break down the mechanics of lithium plating and how anode potential modeling can optimize fast charging protocols.
