CAP-XX Achieves Coveted PSW from Continental Automotive GmbH after Stringent Quality Audit

CAP-XX has successfully completed Continental’s stringent PPAP quality audit to achieve this standard

Sydney, Australia – April 18, 2023 – CAP-XX Limited (LSE:CPX), the leading manufacturer of ultra-thin prismatic, cylindrical, and Lithium-Ion supercapacitors, announced that Continental Automotive GmbH, a global Tier 1 automotive supplier, has granted the highly-coveted PSW (Part Submission Warrant) to CAP-XX, following the company’s successful submission of Continental’s PPAP (Production Part Approval Process) documents necessary to achieve this quality standard. The two companies previously signed a Sourcing Agreement for CAP-XX to supply its DMT220 prismatic supercaps in the volumes needed from 2024 through 2030 for a key Continental automotive program. CAP-XX has now completed the stringent quality audit for this agreement.

Continental’s PPAP analyzed 18 requirements such as design records, FMEAs, authorized engineering changes, engineering approval, dimensional results, and control plan. Also, as part of this PPAP, CAP-XX was successfully audited according to VDA 6.3, a process-based audit standard for improving new product introduction and manufacturing processes, used by German-based automotive industries (Verband der Automobilindustrie).

The CAP-XX DMT220 supercapacitor, previously manufactured by Murata under license from CAP-XX, is now produced in CAP-XX’s new high-capacity factory at Seven Hills, NSW, Australia using production lines acquired and successfully recommissioned from Murata. DMT220 features include:
• 220 mF Capacitance / Rated at 4.2 Volts
• High temperature operation -40°C to 85°C
• Ultra-thin form factor 21 x 14 x 2.2mm thin
• High charge efficiency with long life, up to 20 year or 1,000,000 charge discharge cycles

“Successfully completing the time- and resource-intensive quality standard by meeting the most stringent requirements of the German automotive industry is an endorsement to CAP-XX’s product and manufacturing capabilities, and paves the way for CAP-XX to join other European automotive projects,” said Marco Ranalli, GM of CAP-XX Europe.
