Lead Intelligent Equipment Co (Lead) has announced the launch of a new integrated solid‑state battery stacking and cutting machine in Wuxi, China.
The development represents a major advance in overcoming one of the most critical challenges in next‑generation cell manufacturing: precision stacking at the solid‑solid interface.
Solid‑state batteries replace the liquid electrolyte and separator of conventional lithium‑ion cells with solid electrolytes such as oxides, sulfides and halides. Although these materials vary in their properties, they face the same challenge – establishing a stable, low‑impedance interface that allows efficient lithium‑ion transport.
Precision stacking is therefore vital, ensuring accurate layer alignment, uniform pre‑stress, and compatibility with fragile materials. Yet this process is hindered by technical hurdles: solid electrolytes are highly sensitive to moisture and air, requiring ultra‑dry, sealed environments. Their brittle nature demands specialised pressing and cutting during high‑speed transfer, while maintaining uniform interlayer pressure and ultra‑high precision alignment is essential to avoid voids and short circuits.
Lead’s new machine delivers ultra‑high‑precision processing with ±0.15mm alignment accuracy, dual‑loop pressure/displacement control, and biomimetic suction for zero‑damage handling. Efficiency is boosted through integrated framing, cutting and stacking, achieving throughput above 0.35s/pcs. A modular architecture supports rapid changeovers across a wide range of sizes, while intelligent closed‑loop monitoring ensures real‑time quality assurance.
By combining insulation frame preparation, precision framing, notching, cutting and high‑speed stacking, Lead’s battery stacking and cutting machine is said to set new manufacturing standards and positions the company at the forefront of solid‑state battery production.
