| 摘要： | LGCPI and NREL will build upon the success of the lab-scale work to demonstrate the benefits of the atomic layer deposition (ALD) technique to evaluate the scalability of the ALD coating process, and the benefits of ALD coatings for long term cycling and calendar life. As part of the scalability assessment, direct coating of electrode sheets will be implemented; and the results compared to coating active material powders to fabricate electrode sheets in a subsequent step. To accomplish these steps, NREL will obtain bulk quantities of manganese-rich cathode powder and electrode sheets and coat the samples with help from a subcontractor (ALD Nanosolutions). The coating parameters will be optimized using screening tests carried out at NREL which include fabrication of coin cells from those samples. The powders and electrodes coated under revised conditions will be evaluated by LGCPI in large format pouch cells. |
