a positive temperature gradient along the discharging current facilitates uniform Li+ deposition and local hotspot should be avoided," Shi said. The researchers find that for nonuniform initial ...

Usually, the bigger the temperature gradient, the better the thermoelectric ... Heat from the ambient air causes negative electrons and positive electron “holes” in the material to separate ...

Temperature gradients and heat flow can be equated to ... flow than are those in the horizontal position. This could cause positive temperature anomalies over nonproductive, steeply dipping ...
