智能温度补偿技术助力锂电注液精度进阶

Core Viewpoint - The article discusses the development of an intelligent temperature compensation module by Guangzhou Feisheng Precision Equipment Co., Ltd., which addresses the challenges of liquid electrolyte injection precision in lithium-ion battery manufacturing, particularly in relation to temperature fluctuations [2][3][5]. Group 1: Industry Challenges - The precision of electrolyte injection directly affects battery capacity consistency and product yield, with temperature fluctuations causing significant quality deviations [2]. - For instance, when the ambient temperature rises from 20℃ to 35℃, the actual mass deviation of the injected liquid can reach 1.2% under the same volume, leading to increased capacity dispersion in battery packs [2]. Group 2: Technological Solution - The intelligent temperature compensation module integrates a high-precision temperature sensor (resolution of 0.01℃) within the injection pump, capturing minute temperature changes in real-time and transmitting data to the core controller [5]. - The system employs a thermodynamic compensation model that dynamically analyzes the temperature-density relationship, automatically correcting the injection volume based on target mass parameters [5]. Group 3: Performance and Impact - The system can stabilize injection mass deviation within ±0.05% under temperature variations of ±15℃, achieving over 20 times the precision compared to traditional volumetric measurement methods [7]. - This breakthrough technology enhances the quality measurement characteristics of volumetric injection pumps, addressing the injection process fluctuations caused by temperature drift in the lithium battery industry [7]. - In sectors requiring stringent quality precision, such as new energy battery electrolyte injection and biopharmaceutical standard product packaging, this solution can improve process compliance rates to 99.97% and reduce raw material waste due to temperature drift [7]. Group 4: Future Outlook - As the lithium battery manufacturing industry transitions towards the TWh era, high-precision control technologies will become essential for enhancing manufacturing efficiency and product consistency [8].
