From October 15th to 16th, the 2026 SMM Lithium Battery Raw Materials Conference hosted by Shanghai Nonferrous Metal Network (SMM) was held at the Howard Johnson Agile Hotel in Chengdu.

In the two-day agenda, from global lithium salt supply and demand, nickel and cobalt resource policies, car company battery supply chain reconstruction, to high-pressure lithium iron phosphate, lithium-rich manganese base, and battery recycling - the main line is very clear: Lithium battery competition has changed from "who gets the resources" to "who turns the resources into stable, low-consumption, and deliverable yields."

Outside the venue are the market conditions and policies, while inside the venue are the technology and equipment. The most intuitive feeling of Yifu at the A20 booth is that equipment is no longer a back-end supporting package, but the last step in realizing resource realization.

A20 Booth: More precious than business cards are customers who come with production line sketches

At this conference, Yifu Intelligence will be present at the A20 booth throughout the entire conference. In two days, the resource end, material end, battery end, and equipment end were switched back and forth, and these were the real questions given by SMM on site:

① "When the high-pressure LFP is pushed up, where is the front-end grinding stuck?"

What is stuck is not just the fineness, but also the D50 distribution width, secondary agglomeration and temperature rise. The LPM series uses no screen + special centrifugal separation. Small particles are discharged first, and large particles are ground continuously. The particle size distribution is narrowed, and the error tolerance of sintering and rolling in the later stage is retained.

② "The silicon carbon anode pilot test ran beautifully. Why did the slurry thicken first and then clump when it was enlarged to 400L/1000L?"

It is not just to increase the speed, but to adjust the shear field, residence time, and medium gradation together. The AI ​​intelligent grinding system closes the loop of current, temperature, flow rate, and viscosity to avoid "the human eye is normal, but it will drift away after one inspection".

③ "The old production line horizontal machine cleans the screen every month and eliminates small zirconium beads. The labor and consumables are too much. How to change it?"

We have calculated the same account for several companies on site: after changing to the vertical screenless structure, the media utilization rate is increased to more than 90%, and there is no need to sieve beads regularly. The unit energy consumption is more than 20% lower than traditional equipment. Maintenance has changed from "many people per month" to "one person every half a year."

④ "The solid electrode slurry has high solid content and high viscosity, and the ordinary sand mill will clog as soon as it is measured. What should I do?"

It depends on the separation structure and cavity flow field. Yifu LPM can be adapted to microbeads below 0.03mm, challenging the limit of finer grinding while simultaneously controlling the risk of metal foreign matter and clogging.

The hidden main line of this conference is very clear - lithium battery has switched from "production expansion narrative" to "operation narrative". Equipment is not a purchase item at the end of the production line, but an invisible base for material yield and manufacturing cost.

In the lithium battery raw material track, Yifu has delivered a set of equipment solutions "from resources to yield"

Facing the parallel expansion of LFP high-pressure, silicon-carbon anode, sodium-based/manganese-based/solid-state and other multiple systems, Yifu highlighted four lines of capabilities at Chengdu A20:

🔹 LPM series vertical nano-ceramic sand mill (1L-1000L/2000L)

Laboratory conclusion The same principle is scaled up to the production line, without re-adjustment, relying on separation structure + medium kinematics reuse.

🔹 High-pressure LFP precursor dispersion-grinding-grading system

Solve viscosity changes, network blocking, and batch D50 drift, helping customers retain "fineness" and "non-crystallization" at the same time.

🔹 Silicon carbon/hard carbon/artificial graphite negative electrode wet grinding platform

Multiple system materials share the baseline, reducing the idle rate of equipment, and there is no need to repeatedly buy lines for new project expansion.

🔹 High solid content dispersion solution for solid-state battery electrode slurry

Control temperature rise, metal foreign matter, and slurry stability, suitable for all-solid/semi-solid pilot testing to mass production.

The cost saved on the resource side will be wasted if the front-end grinding is missed - Yifu is the gate that turns "resources" into "yield rate".

The closing is not the end, but the beginning of 1V1 production line diagnosis

The two days in Chengdu ended, but the samples, production line sketches, and energy consumption accounts left on the booth have not yet been read. The SMM industry exhibition is no longer just about "looking at prices and supply and demand". The heads of procurement, process, engineering, and production lines appear in the same frame - equipment manufacturers are being drawn into project meetings earlier and earlier.

What Yifu needs to do is not to chase the market, but to steadily grind every resource premium of lithium battery materials into a production line yield that is consistent in batches and has controllable energy consumption.

The next stop is Shaoxing, Yifu will go to the renewable energy appointment with you!
