TDK

TDK appears in E229｜从手工作坊到全球第一：中国动力电池逆袭史 as the company whose magnetic-tape background gave it precision coating experience. The episode says that after TDK acquired ATL / Amperex Technology Limited, coating and process-control capabilities helped ATL improve battery manufacturing.

The source’s use of TDK is narrow but important: it shows why Battery Manufacturing Know-How is often inherited from adjacent industries rather than invented entirely inside a battery startup.
