华视集团曹国平谈精密智造：从1%抽检到100%全检，电池制造重新定标

Core Viewpoint - Precision manufacturing and industrial testing are becoming the foundational infrastructure that defines the upper limits of product quality and the lower limits of cost in battery manufacturing [1][20]. Group 1: Manufacturing and Testing Innovations - The core of battery manufacturing is understanding the areal density of electrode materials, which is crucial for quality control [2][4]. - The industry has shifted from 1% sampling to 100% inspection of electrode materials, enabling comprehensive quality assurance [5][7]. - The implementation of full-width density inspection allows for real-time feedback and optimization of manufacturing processes, significantly reducing machine adjustment times and waste [9][10]. Group 2: Cost Reduction Strategies - By optimizing the N/P ratio from 1.15 to 1.10 through precise density measurements, significant cost savings of approximately 6.6 million yuan per production line annually can be achieved [10]. - The use of full inspection data allows for better capacity consistency management, moving the quality control process upstream in the manufacturing workflow [11][12]. Group 3: Advanced Detection Technologies - Industrial CT technology is being developed to address internal structural inspections, although its current application is limited due to time and cost constraints [13][14]. - Innovations in offline and online CT systems aim to enhance defect detection while reducing inspection times to as low as 4 seconds [15][16]. - The development of a semiconductor gas sensor for leak detection significantly lowers costs and improves efficiency compared to traditional methods [18]. Group 4: Market Positioning and Future Trends - The integration of precision manufacturing and industrial testing is becoming essential for maintaining competitive advantages in a diversifying battery technology landscape [20]. - Companies that excel in establishing robust quality and cost control infrastructures will be better positioned in the evolving market dynamics of safety, cost, and technological diversity [20].
