 The study found that a co-base ternary oxide material with moderate affinity for lithium polysulfides was able to promote three-dimensional lithium sulfide growth on its surface, resulting in higher sulfur utilization and better battery performance than other materials with either weak or strong affinities. This suggests that a balance between promoting lithium polysulfide adsorption and limiting their diffusion within the material's surface can be used to optimize sulfur utilization and battery performance.
