Yes, that will be prior art that will prevent any claims having Lithium as an essential catalyst for LENR after you published it.
PersonallyI doubt that Lithium plays an essential role. As Me356 also indicated he does not need Lithium. The presence of Lithium may cause Lithium transmutations, but as we all know there are other transmutations possible (e.g. Nickel).
To add more personal thoughts: I think that UDH (Ultra Dense Hydrogen) is the key. Holmlid has already publications on that (and by that also prior art on how to produce UDH with catalysts he mentions).
I think Me356 said that he did not need lithium aluminum hydride but he used pure lithium instead. Aluminum moderates the lithium reaction. I could be wrong, I don't read every word on every post. I will concede this point and be surprised if you can find a reference in a post were Me or anybody else can produce the Rossi type reaction without lithium added to the fuel mix.
