The application belongs to the technical field of battery preheating, and particularly relates to a fast-response in-situ temperature control binder as well as a preparation method and application thereof. The application proposes a new binder, which uses hyperbranched polymers carrying a large number of charges to load fast-response particles through electrostatic interaction and redox reaction, and designs an external miniature heating device cooperating with the fast-response binder, so that the impedance of the battery is not increased, and the effect of non-contact fast heating of the battery interior can be achieved only by using the binder when assembling the battery and cooperating with the external device. The battery can be raised from minus 60 degrees Celsius to room temperature in 5 seconds, and the battery in hibernation due to low temperature can be quickly woken up to discharge and work again. The application has great significance for the field of battery low-temperature preheating, and provides a brand-new heating strategy, which creates an unprecedented new idea for the use of the battery at low temperature.
