The purpose is Li-intercalation, for which, I currently use LiBH4 or n-BuLi. As these chemicals are difficult to handle, I am looking for alternatives. The temperature range I am interested in is below 1000 Celsius.
Any relevant reading suggestions are also much appreciated. Thanks
Both compounds form LiH (LiBH4 >300oC, LiR >150oC). You can try to use LiH directly as it is relative stable in dry air and react slowly with air moisture.
2Li2O + 2CaO +Si = 2CaOxSiO2 + 4Li
The output of lithium is 80% of the theoretical.
If there is a chance that metallic lithium will be present during disassembly, then both moisture and oxygen should be restricted from entering the disassembly environment. Even though it is generally accepted that lithium in its metallic state does not contribute to a battery’s faradic process, there are situations in which metallic lithium could exist on or within the battery electrodes. It was suggested that the possibility of lithium plating on carbonaceous anodes during low-temperature charging conditions. Reduced temperature can hinder ion diffusion into the graphite electrode, causing lithium to build up on the electrode surface. This build up can lead to dendrite formation, which may cause internal short circuits during operation but could also cause problems during disassembly due to lithium’s reactivity in air. This process is thought to be reversible upon discharge, and, therefore, is more relevant in cells disassembled in a charged state.
