Abstract
Self-terminated oligomers with hyperbranched architecture, also known as STOBA, are combined with lithium-ion battery cathode materials by two different ways: mechanical blending and surface coating. The comparative electrochemical analyses of the assembled coin cells demonstrate that for the materials gained through mechanical blending, no blocking effects are observed at high-temperature condition. For the surface coating ones, STOBA has slight impact on the cell performance at room temperature, but when the ambient temperature exceeds the cross-linking temperature, large area of cross-linking will occur on the surface of the electrode materials, which prevents the lithium ion from extracting and inserting. As a result, the battery totally loses charge–discharge capacity in the high rate discharge condition to ensure the safety when operating at high temperatures.
