Embodiment 1
[0050] This embodiment is used to illustrate the self-dissipating device disclosed in the present invention and its preparation method.
[0051] Set the specific gravity to 0.9g / cm 3 , a cooling agent with a pH of 7.2 (0.4 parts by volume of ethoxylated tallow amine with an ethoxy content of 2mol / mol, 0.01 parts by volume of n-nonanoic acid, 0.29 parts by volume of n-octanol and 99.3 parts by volume of water) from Fill the liquid injection port into the heat dissipation box until the volume of the cooling agent accounts for 10% of the volume of the heat dissipation box, and seal the liquid injection port.
[0052] Charge the battery with a constant current of 850mA until the voltage reaches 4.2V, then charge with a constant voltage of 4.2V, and the conventional charging ends when the current drops to 34mA. Set aside for 10min.
[0053] The heat dissipation box was fixed on the surface of the above-mentioned battery to obtain a self-radiation device S1.
Embodiment 2
[0055] This embodiment is used to illustrate the self-dissipating device disclosed in the present invention and its preparation method.
[0056] Set the specific gravity to 0.99g / cm 3 , a cooling agent with a pH of 6.5 (0.04 parts by volume of ethoxylated tallow amine with an ethoxy content of 10 mol / mol, 0.66 parts by volume of isooctanoic acid, 0.05 parts by volume of isodecyl alcohol, and 99.25 parts by volume of water) from the injection The liquid port is injected into the cooling box body until the volume of the cooling agent accounts for 40% of the volume of the cooling box body, and the liquid injection port is sealed.
[0057] Charge the battery with a constant current of 850mA until the voltage reaches 4.2V, then charge with a constant voltage of 4.2V, and the conventional charging ends when the current drops to 34mA. Set aside for 10min.
