Tiny Tweaks, Big Impact A New Way to Boost EV Battery Life

Big news for the future of electric vehicles馃攱

A new computational study, supported by experimental observations led by Prof. Dan Thomas Major, collaborating with Prof. Doron Aurbach, demonstrates how introducing tiny amounts less than 1% of certain metal dopants into Ni-rich NCM cathodes can dramatically improve lithium-ion battery performance.

These cathodes already offer high energy capacity, but they tend to degrade quickly under cycling. Prof. Major's team found that adding dopants like niobium, tungsten, or molybdenum helps:

路Strengthen the structure by forming tighter bonds with oxygen
路Reduce the amount of unstable and reactive nickel ions
路Stabilize the surface to limit oxygen loss during charge cycles
路Maintain battery performance over time without sacrificing output

What does this mean for the planet? Batteries that last longer, perform more reliably, and waste less material are an essential step toward making electrified transportation more sustainable.

Brilliant work from Prof. Dan Thomas Major, Prof. Doron Aurbach, and the team.
