The invention discloses a
siloxane-terminated polyether type
lithium battery
adhesive and a preparation method thereof. The preparation method comprises the following steps: 1) sequentially adding a
solvent and
cyanate into a reaction
bottle, performing stirring and mixing, further adding a
phase transfer catalyst, performing heating to 70-100 DEG C, and performing uniform constant temperature activation and dispersion for 30 minutes; and 2) respectively dropwise adding measured
chlorosilane and polyether
alcohol, or
chlorosilane and
polyester alcohol into the activation solution in the step 1), increasing the
exothermic reaction temperature to 90-120 DEG C, maintaining the temperature range, performing a
continuous reaction for 6-8 hours, after the reaction is completed, performing cooling to the
room temperature, performing filtering so as to obtain filtrate, and removing the
solvent, so as to obtain the
siloxane-terminated polyether type
lithium battery
adhesive. The
siloxane-terminated polyether type
lithium battery
adhesive disclosed by the invention is simple in preparation method, low in cost, high in efficiency, fast in adhesion and easy in industrialization. Prepared siloxane-terminated polyether for adhesion of lithium batteries is capable of improving the efficiency of the lithium batteries, high and low
temperature resistance, stable
charge and discharge efficiencyand bonding properties of the lithium batteries.
