Xiaomi and Nio each take a 3.6% stake in Shifang Intelligent Manufacturing, positioning themselves in digital inkjet printing for power batteries to secure a foothold in next-generation manufacturing technology.
When Xiaomi's Hanxing Venture Capital and NIO's Hefei NIO Industrial Fund simultaneously appeared in the newly added shareholder roster of Shenzhen Shifang Intelligent Manufacturing Technology Co., Ltd. at the beginning of September, each taking an extremely restrained and completely identical tiny equity stake of 3.6082%, what the smart electric vehicle circle and the high-end equipment manufacturing circle sensed was by no means just another ordinary early-stage financial follow-on investment. The industrial capital controlled by Lei Jun and Li Bin respectively sitting precisely "on equal footing" within the same unlisted hardware startup—this highly synchronized pace tears open the technology deep-water positioning battle that host manufacturers have launched after exhausting range, battery pack structures (CTP/CTC), and smart cockpits, now targeting power battery extreme manufacturing, insulating coating processes, and the underlying layers of thermal runaway safety.
Power Battery Safety and Lightweight Manufacturing Are Approaching the Limits of Traditional Physical Processes
Power battery safety and lightweight manufacturing are approaching the limits of traditional physical processes. In pursuit of ultimate space utilization and grouping efficiency, within power battery systems (whether large cylindrical, prismatic aluminum-shell, or blade-type configurations), the gaps between cells and between cells and cold plates have been compressed to the millimeter or even micron level. In this extremely cramped structure, functional coatings for insulation, flame retardancy, thermal conduction and temperature uniformity, and high-voltage breakdown resistance are the core barriers preventing cascading battery thermal runaway.
However, the traditional adhesive tape, dip coating, or roller coating processes long relied upon by the industry not only face engineering defects such as uneven micron-level coating thickness of high-viscosity materials and edge glue overflow and foaming, but also require re-mold opening for model changes, severely dragging down production line yield and takt time.Whoever can push traditional rough physical coating toward high-precision digital jet printing will be the first to break through in battery pack safety redundancy and manufacturing cost reduction.
The Industrial and Commercial Footprints of the Two Major Automaking Forces' Capital Layout
Following the underlying industrial and commercial footprints to penetrate the capital chassis of this hard-tech dark horse, the layout traces of the two major automaking forces are clearly presented in Tianyancha archives. Tianyancha industrial and commercial data shows that Shenzhen Shifang Intelligent Manufacturing Technology Co., Ltd. completed a key industrial and commercial change on September 1, with registered capital increasing from approximately 23.6769 million yuan to approximately 25.5185 million yuan, an increase of about 7.8%.
In the shareholder capital increase details recorded by Tianyancha, Hanxing Venture Capital Co., Ltd. and Hefei NIO Industrial Development Equity Investment Partnership (Limited Partnership) each entered in parallel with a subscribed capital contribution of 920,800 yuan, with their shareholding ratio precisely locked at 3.6082%.
The overall equity expansion of 7.8% and the equity allocation of less than 4% each for the two parties demonstrate the typical CVC (Corporate Venture Capital) strategic betting approach when facing underlying disruptive processes.
The two host manufacturers are not seeking control over the startup, but rather exchanging an extremely small capital exposure for key "industrial priority observation rights" and customized development interfaces. Shifang Intelligent Manufacturing's flagship UV inkjet printing engine precisely conquers the world-class challenge of industrial-grade micron-level precise jetting of high-viscosity fluids. By magically adapting the digital inkjet principle originally used for consumer-grade printing into direct on-line film formation of high-viscosity insulating flame-retardant coatings, it can completely eliminate traditional insulating blue film and manual attachment processes, achieving micron-level precise thickness control on three-dimensional irregular cell surfaces.
Xiaomi Auto's Production Line Demands
For Xiaomi Auto, the SU7 and subsequent pure electric SUV models all come standard with high-voltage platforms and CTB integrated battery technology, placing extremely high production line requirements on high-voltage insulation protection at the cell level and automated assembly takt time. With Shifang Intelligent Manufacturing's digital jet printing solution, the equipment footprint and material waste in the super factory's battery pack workshop can be significantly compressed.
NIO's Unique Battery Swap Architecture Requirements
For NIO, which has long adhered to a high-voltage battery swap architecture with strict requirements for battery pack specification interchangeability, battery housings under battery swap operating conditions face extremely high-frequency mechanical vibration and alternating humid-heat stress. Traditional film aging and edge lifting are potential hidden dangers in long-term service, while the dense in-situ film structure formed by micron-level digital jet printing can greatly improve the corrosion resistance and insulation breakdown limit of long-life battery packs.
Domestic Self-Control of the High-End Industrial Equipment Supply Chain
A deeper practical driver lies in the domestic self-control of the high-end industrial equipment supply chain.
For a long time, industrial-grade high-precision piezoelectric printheads and microfluidic core components have been almost entirely monopolized by multinational giants such as Japan's Fujifilm, Ricoh, and Konica Minolta, with the vast majority of domestic integrators long reduced to "system integrators" that purchase printheads and assemble casings.The core reason Shifang Intelligent Manufacturing could simultaneously attract Five Source Capital, Creation Partners, Hengxu Capital (SAIC-affiliated), as well as Xiaomi and NIO to jointly participate in the B+ round and secure hundreds of millions of yuan in ammunition lies in its attempt to build a closed loop of independent intellectual property rights in printhead drive control, high-viscosity flow channel design, and curing processes.
Mass Production Landing Still Faces Numerous Dangerous Shoals
However, this seemingly sexy process disruption still faces numerous dangerous shoals in large-scale mass production landing on the industrial site.
The high precision achieved in the laboratory and prototype proofing stage does not equal all-weather stability on automotive-grade battery production lines. Power battery OEMs have zero-tolerance line stoppage assessments for the ultra-high production pace (PPM) of producing dozens of cells per minute. During high-speed jetting of high-viscosity functional slurries, fatal process hazards such as nozzle micro-clogging, micron-level ink splatter, and pinhole defects are extremely prone to occur. Once poor insulation caused by missed spraying flows into the next process, the consequences are unimaginable.
In addition, from equipment proofing to passing the host manufacturer's stringent automotive verification lasting one to two years (covering withstand voltage testing, salt spray corrosion testing, and thermal shock cycling), the high costs of non-standard production line debugging and customization during this period will continue to test Shifang Intelligent Manufacturing's cash flow throughput capacity.
Industry Weather Vane: The Arms Race Sounds at the Edge of Micron-Level Nozzles
This capital convergence occurring in early autumn releases the clearest industry signal to the entire smart hardware and new energy supply chain: The vehicle hardware integration of new energy vehicles has entered a bottleneck period, and the true process moat is shifting upstream to the depths of extremely hidden coating materials, precision fluid control, and digital inkjet equipment. When new automaking forces are no longer satisfied with purchasing standardized battery packs from major battery manufacturers, but instead personally enter the field to invest in every underlying component manufacturing equipment that may improve energy density and insulation safety, the arms race of the next generation of advanced manufacturing has long since silently begun at the edge of micron-level nozzles.
