Blended Positive Electrodes for Li‐Ion Batteries: From Empiricism to Rational Design

Physical mixtures (i. e. blends) of two or more active materials are often used in commercial batteries to achieve better performance than what can be attained with a single component. This approach has been empirically driven and found to result in relevant synergistic improvements that are unfortu...
