INSIGHT 01Fact
77%
2,856 applications in this field, 2,730 of them in IPC H01M (Batteries, electrochemical cells) — the main axis of the portfolio.
Method: Field applications ÷ applications with IPC
INSIGHT 02Fact
24%
Measurement, machine tools, handling and chemical engineering together reach 887, mostly production-line, equipment and inspection filings.
Method: Four fields added ÷ all applications (fields may overlap)
INSIGHT 03Fact
52%
1,940 utility models and 1,788 inventions. Structural and tooling improvements are often protected faster as utility models.
Method: Utility model documents ÷ all documents
3,728 applications with IPC codes are mapped to 35 fields using the WIPO IPC–Technology Concordance; area is the number of applications. Select a tile to see its IPC subclasses. An application can belong to several fields.
Publications per month in each field; brighter cells mean more. It shows which directions surge in particular months.

Organisations that filed jointly with the reviewed entities; line weight is the number of joint applications. Gold marks possibly related entities whose names carry the group's trade name; blue marks external partners.
“Possibly related” only means the name contains the group's trade name; ownership has not been verified, and their own filings are not counted here.
Written by editors after reading the patent texts and company materials. Verified facts and inferences are labeled, each with evidence and limits.
Inference
水冷板通过内外通道安排兼顾换热和变形空间；电池挂载方案则涉及电芯大面连接与支撑。样本提示热、力、结构约束可以放在同一系统问题下研究。
Verified fact
负极面密度与电解液电导率的约束，以及极片容量、面密度与电导率的关联条件，显示材料相关布局并非只由一种材料名称概括。
Inference
退役磷酸铁锂前驱体制备和电解质制造废料回收分别处理退役端与生产端问题。公司2025年报介绍同时披露回收业务，可支持其关注循环利用的判断。

Titles come from the source bibliography. Select a number to read the full document on this site.
Publications are deduplicated by publication number; applications by application number, so a publication and its grant count once; families by the source family ID. Technology fields are derived automatically from IPC codes using the WIPO IPC–Technology Concordance (March 2026), without manual or AI labeling.
This page does not count patents in force: a grant document does not mean the right is still valid. Legal status and current owners must be checked with CNIPA.
These statistics use only the applicant names and publication dates collected for this snapshot. They do not represent the full company or group portfolio.
