The splat test is usually generated by low feed rate cold spraying of particles onto an as-polished substrate and it can be considered as a monolayer coating deposition. In this study, in order to investigate cold spray deposition mechanisms, Fe splats were sprayed onto the cold-sprayed single component 316L, Fe, and a composite 90Fe coatings. Results showed that although there is only 3.6 vol.% of 316L in the composite 90Fe coating, Fe splats exhibit a much better deposition behavior onto the 90Fe as compared with the single component Fe coating. To explain this observation, Fe splat samples were characterized using the scanning electron microscope (SEM), optical profilometry, splat adhesion tests, and splat nanoindentation. Finally, a preliminary explanation towards the Fe splat deposition behavior onto the composite coating was drawn.

The prelithiation of hard carbon electrode using stable metal lithium powder to compensate the lithium loss during the first lithium insertion is studied in this work. The results show that when the pressure on lithium powder surface is 6 MPa, the Li2CO3 protective layer on the surface of stable metal lithium powder is completely squeezed, which is conducive due to the full contact between the metal lithium and the hard carbon. The prelithiation of hard carbon has little effect on the initial charge capacity and cycle life. Both the pre-lithium capacity and the utilization efficiency of lithium powder increase with the increasing of the lithium powder content, and when the amount of lithium powder is 3 g m−2, the utilization efficiency of lithium powder is 56%.
