OFFICIAL TECHNOLOGY CATALOGUE ENTRY

Technology for producing battery cathode materials

Technology · export restricted

Direct answer: Technology for producing battery cathode materials appears in the official technology catalogue. The control points describe the relevant scope. The complete official text and transaction facts still govern.

A match = verify the official text; no match ≠ uncontrolled。 This index is not legal advice.

Reviewed English rendering of the control points

1. Technology for producing lithium iron phosphate for batteries that simultaneously meets these conditions: (a) the chemical formula is LixFeyMzPO4, where x, y and z are at least 0 and M is one or more elements other than Li and Fe; and (b) at 220 MPa, powder compacted density is at least 2.58 g/cc, 0.1C discharge specific capacity is at least 160 mAh/g, and initial coulombic efficiency is at least 97%. 2. Technology for producing lithium manganese iron phosphate for batteries that simultaneously meets these conditions: (a) the chemical formula is LixFeyMnzMaPO4, where x, y, z and a are at least 0 and M is one or more elements other than Li, Fe and Mn; and (b) at 220 MPa, powder compacted density is at least 2.38 g/cc, initial coulombic efficiency at 0.1C is at least 95%, discharge specific capacity at 0.1C is at least 155 mAh/g, and average voltage at 0.1C is at least 3.85 V. 3. Technology for producing phosphate cathode precursor materials, including processes for iron phosphate, manganese iron phosphate, battery-grade ferrous oxalate, battery-grade lithium dihydrogen or hydrogen phosphate, and lithium phosphate. The iron phosphate must have a tap density above 1.2 g/cc and magnetic impurities below 10 ppb.

Practical verification checklist

Scope · evidence · decision trail

Use the steps below to review this page. Verify the complete official text before making a decision. Seek qualified advice when needed.

  1. Define the decision

    State the exact decision, owner, deadline, trade direction and required evidence. Do this before you search.

  2. Identify every party

    Confirm each legal name and alias. Check registration, ownership, control, intermediaries, carriers, banks and beneficial owners.

  3. Describe the item

    Record the item’s function, operating principle, material, model and performance. Include software, technology, accessories and decisive parameters.

  4. Check classification

    Treat customs and export-control classification as separate tasks. Keep the facts, assumptions and reasoning for each result.

  5. Map the route

    Confirm origin, departure, destination and transit points. Include re-export, remote access, technology transfer and each delivery path.

  6. Verify end use

    Identify the stated purpose and real operating environment. Check integration, sensitive sectors, military links and prohibited uses.

  7. Verify end users

    Check the purchaser, consignee, end user, operator and parent company. Identify anyone who can redirect or control the item.

  8. Read the complete source

    Treat a search result as a lead. Read the official scope, definitions, notes, exclusions, annexes and licence conditions.

  9. Check current measures

    Use the version effective on the transaction date. Review later notices, temporary controls, destination measures and policy changes.

  10. Test exceptions carefully

    Prove every condition before using an exception or exemption. Apply the same rule to licence facilitation and general authorisations.

  11. Resolve contradictions

    Pause when names, codes, documents, routes, prices or explanations conflict. Obtain evidence instead of filling gaps with assumptions.

  12. Escalate uncertainty

    Send unresolved questions to the compliance owner or a qualified adviser. This includes classification, ownership, use, destination and licensing.

  13. Keep an audit trail

    Keep source links, files, checksums, screenshots, search terms and results. Record the reviewer, approvals and final reasoning.

  14. Schedule re-checks

    Set a new review date for open transactions. Re-check changing parties, destinations, specifications, official lists and licences.
