transition metals, battery performance, capacity fade

Transition metals can make or break battery life. Transition metals are essential in lithium-ion batteries, contributing to their performance and longevity. However, their dissolution from the cathode can lead to capacity fade, [a significant issue in battery degradation](https://pubs.acs.org/doi/10.1021/acs.jpcc.3c01396). This dissolution process is often linked to unwanted side reactions during ion movement, [which can cause structural instability and loss of active material](https://www.electrochem.org/why-your-battery-doesnt-last-forever). [Addressing these challenges is crucial for improving battery lifespan and performance](https://www.electrochem.org/ecsnews/new-cathode-coatings-li-ion-batteries-extend-lifespan/).

Coulombic Efficiency

Coulombic efficiency is a measure of how effectively a battery can store and release energy. Low efficiency during cycling can hinder the application of cobalt-free materials, which are crucial for reducing reliance on scarce resources. Improving this efficiency is essential for enhancing the energy density and practical applicability of batteries. Researchers are exploring various strategies to boost coulombic efficiency, which could lead to longer-lasting and more efficient batteries.
