I believe the correct term is "thermal conductivity". The thermal conductivity of a part is measured in Watts per Kelvin. Adding a heat sink to a part provides a low-thermal-resistance path to a larger surface area of air, which allows more Watts of heat dissipation per Kelvin of temperature difference between the part and the …

Heat is generated from other than effective power. Effective power is used to drive the load. Thus, "4.2V * 3A * 30/60h" is a straight calculation of (though need some more considerations) power we are drawing from the battery, but not the power to generate heat. Heat is generated from "inefficiency", offset to an ideal power source.
After obtaining the battery specific heat capacity, adiabatic temperature rise and other parameters, one can calculate the instantaneous heat generation power of the …
