To return to a previous story published here on ECW, I read this study by a team of Austrian researchers on thermal runaway in lithium cells that gives more information:

Here is the abstract of the article:
Li-ion batteries play an ever-increasing role in our daily life. Therefore, it is important to understand the potential risks involved with these devices. In this work we demonstrate the thermal runaway characteristics of three types of commercially available Li-ion batteries with the format 18650. The Li-ion batteries were deliberately driven into thermal runaway by overheating under controlled conditions. Cell temperatures up to 850 °C and a gas release of up to 0.27 mol were measured. The main gas components were quantified with gas-chromatography. The safety of Li-ion batteries is determined by their composition, size, energy content, design and quality. This work investigated the influence of different cathode-material chemistry on the safety of commercial graphite-based 18650 cells. The active cathode materials of the three tested cell types were (a) LiFePO4, (b) Li(Ni0.45Mn0.45Co0.10)O2 and (c) a blend of LiCoO2 and Li(Ni0.50Mn0.25Co0.25)O2.
First, I was surprised to see how fast the temperature of these cells can increase. According to the authors: in a few seconds the temperature of the reactor can reach 900C. A rapid computation of my own shows that the power resulting from this extreme temperature rise corresponds to a power in the range of several kW.
If we take the volume of the reactor to be around 20 liters — assuming it to be full of air ( let say 28g) — and a temperature increase ΔT= 800C the producted energy Q in J could be about:
Q = m x Cp x ΔT Cp being the air heat capacity 1J/g/deg.C
28g x 1x 800= 20,400J /second or = 20.4kW !
I doubt that could be explained by the multiple chemical reactions that the author gives in her paper.
Remarkably, also the power output lasts a relatively long time on its own. See Fig.5 from the study below.
In addition, we have all the ingredients of LENR and the range of energy output of Rossi reactor!
I really think after doing the maths from the results of the study, that there is evidence for LENR. The authors don’t see it — but the output range and the fact that the reaction lasts a relatively long time shows to me that it could be a cold fusion reaction.
Could we be looking for something that is already in front of us or in our pocket?
