摘要

In the article, we employed and extended the chemomechanical model for a hollow spherical particle to account for different optimization strategies for improved battery performance. In particular, we assessed the influence of surface tension and coating on a hollow particle. We have shown that hollow spherical particles can significantly reduce the charging time with only a small sacrifice of the theoretical capacity. Surface tension, however, plays a negligible role in the hollow as in a solid spherical particle, when the particle is synthesized at micro-level. Finally, we assess the influence of the coating on the hollow particle and found that it can effectively push the whole active particle into a compressive state.
