As I understand the problem, the large note 7 had a large display and needed a lot of battery energy. Yet, everybody wants a slim phone. The Li-ion battery they designed had internal separators that were too thin. When the battery ages, it swells, even though it hasn't lost capacity. The case pushes back on the swollen battery pack and in the case of the note 7 the separator punctured and allowed the cell to short out. When the cell shorts, a tremendous current flows causing localized heating that melts the plastic pouch and exposes the Li compound to air where it starts fire.
There is no need to invoke LENR to explain the problem. In fact, there are plenty of Li batteries with more Li inside that never experience this problem.
