Customer ServiceIn this study, a novel method of applying a Lithium titanate (LTO) active coating on the separator of Li-ion batteries is proposed. The LTO active coating can participate in electrochemical reactions and provide additional capacity.
The separator with active coating exhibits the highest ionic conductivity of 1.45 mS/cm, the lowest thermal shrinkage of 1.1% at 160 °C, and the highest capacity of 80.2 mAh/g at 15 C among the tested separators. This method offers a simple and effective way to enhance the performance of Li-ion batteries.
Coatings of different materials (metals, oxides, nitrides, etc.) on the separator have good mechanical properties and can promote the uniform passage and deposition of Li +, which effectively inhibits the growth of lithium dendrites.
To achieve the commercial application of the active material coated separators for high energy and safe batteries, the factors involving performance, industrial production, and cost should be considered. The cathode-material-coated separator can improve the capacity, rate performance, and thermal stability of the batteries.
In addition, the LTO coating layer can enhance the Li-ion transport and unify Li-ion flux, preventing the growth of lithium dendrite. This method offers a simple and effective way to enhance the performance and safety of LIBs by using an active coating on the separator.
As expected, coating the separator with HPA particles increases the electrolyte uptake. The rate capability of the coated separators in Li-ion batteries was significantly affected by the calendering process, primarily due to changes in coating compactness and surface morphology.
