CICC: Supercapacitor Penetration Rises, Ushering in Supply Shortage Cycle
Summary
CICC research report notes that supercapacitors fill the millisecond-to-second high-power pulse gap in AIDC power supplies and provide backup power. With the adoption of 800VDC architecture, the supercapacitor load per watt of rack increases, and penetration rises rapidly. Due to high technical and certification barriers, despite seemingly ample nominal capacity, effective capacity for large-capacity units is tight, and a supply shortage cycle is expected in 2027-2028.
Bubble analysis
This news is indirectly related to the AI investment bubble: it discusses a niche segment (supercapacitors) in the power supply chain of AI data centers, a supporting industry for AI infrastructure. Although it does not directly involve capex or valuations, the expectation of supply shortages could affect AI hardware costs, indirectly impacting AI investment returns.
