Composite Polymer Binder for Thermal Stability

The patent applies parameter changes by utilizing the phase transition temperature of the polymer binder. The binder is designed to undergo a specific physical change (phase transition) at temperatures of 50°C or higher, which fundamentally alters its properties from a normal binding state to a safety-responsive state. This parameter change enables the binder to automatically reduce ion permeability and lower charge/discharge performance when abnormal heat is detected, thereby resolving the contradiction between maintaining normal performance and responding to abnormal temperature conditions.

The patent implements dynamics by creating a binder that dynamically adjusts its properties based on temperature conditions. The polymer binder transitions from a static binding function at normal temperatures to an active safety mechanism at elevated temperatures. This dynamic behavior allows the system to adapt its charge/discharge characteristics in real-time according to thermal conditions, enabling the battery to maintain reliability across different temperature scenarios while automatically mitigating heat generation risks.

The patent utilizes parameter changes by designing the polymer binder with a specific phase transition temperature (50°C or higher). Below this temperature, the binder maintains its normal binding strength and structural integrity. When the temperature reaches or exceeds the phase transition point, the binder undergoes a physical change that reduces its ion permeability and binding strength, thereby automatically lowering charge/discharge performance. This parameter-driven transformation resolves the contradiction by enabling the binder to switch between strong binding mode and performance-limited mode based on thermal conditions.

The patent applies dynamics by creating a temperature-responsive binder that dynamically adjusts its binding characteristics. At normal operating temperatures, the binder provides strong adhesion to maintain electrode integrity. When abnormal heat is generated and temperature reaches the phase transition point, the binder dynamically transforms its properties to reduce binding strength and ion transport, thereby automatically limiting charge/discharge performance. This dynamic adaptation allows the system to preserve electrode strength during normal operation while automatically reducing productivity under abnormal thermal conditions.
