精密智造与工业检测正在变成定义产品上限、成本下限的基础设施。 " 当前我们制造电池的核心，就是要把极片的面密度看清楚 —— 你得精准知道这一卷材料里到底 有多少活性物质。 " 摘要 11 月 18 日，在 2025 高工锂电年会 " 电池多样化体系的创新 " 专场上，南京华视 集团 董事 长曹国平，用这句话点明了自己要讲的重点。 在题为《精密智造与工业检测新技术赋能电池多元创新》的演讲中，他从全幅宽面密度全检讲到卷 绕、叠片前移的一致性控制，再到工业 CT 和二次氦检替代方案，试图回答一个问题： 当电池技术路线走向多元，制造和检测能力如何把质量与成本的 " 地板 " 打牢。 从1%抽检到100%全检：把极片"看清楚" 在极片制造环节，行业长期习惯于扫描式 X 射线面密度检测：光斑直径只有几十毫米，实质是抽 检，覆盖率往往只有 1%–1.8% ，既难以真实反映面密度和厚度一致性，也难以支撑高精度的涂 布闭环控制。 华视给出的方案，是把抽检变成全检。 他们把长条形 X 射线光斑和线阵半导体探测器铺满极片全幅宽，实现线扫式 100% 覆盖；配合 自研的软件系统、自动标定与水冷系统等，把传统 " 点测 " 变成 " ...
