What Challenges Do Prismatic Cell Manufacturers Face?

Prismatic cell manufacturing demands more than standard automation—it requires precision-engineered process integration, advanced control systems, and comprehensive technical support.

Manufacturers face critical challenges that directly impact efficiency and profitability: maintaining quality at high speeds, achieving seamless process coordination, and scaling operations while meeting strict compliance requirements.

Equipment–Process Mismatch

As battery chemistries evolve and cell designs become more diverse, many production lines struggle to keep pace.
  • Incompatibility with LFP, NCM, and other chemistries
  • Limited adaptability to different prismatic cell sizes and structural formats
  • Lack of support for both stacking and lamination-based processes
  • Inefficient line layouts that restrict flexibility and expansion

Precision & Consistency Challenges

Small deviations in the electrode, stacking, sealing, or welding stages can lead to severe product defects.
  • Uneven slurry coating or excessive burrs after slitting
  • Misalignment during stacking or tab welding reduces energy density
  • Unstable sealing temperature, vacuum level, or pressure leads to gas leakage or swelling
  • Variations in electrolyte filling volume compromise cell performance and safety

Limited Automation & Throughput

In many facilities, semi-automated operations and disconnected equipment reduce production speed and raise labor costs.
  • Manual handling creates bottlenecks between key processes
  • Poor coordination between upstream and downstream sections of the line
  • Difficult to achieve high-speed takt time (e.g. 0.15–0.2s per cell) required for mass production

Yield Loss & Quality Control Gaps

Without precision engineering and robust inspection, yield rates suffer — especially in new product introduction (NPI) phases.
  • Inconsistent flanging, stacking, or crimping leads to high rejection rates
  • Errors in electrolyte filling or sealing lead to swelling, leakage, or poor cycle life
  • Low accuracy in formation and capacity grading impacts final product consistency

Long Lead Times & Technical Support Deficiencies

Battery projects operate on tight schedules. Any delay in equipment delivery, commissioning, or troubleshooting can stall production.
  • Extended lead times and unclear project timelines
  • Lack of responsive after-sales service or local engineering teams
  • Inadequate operator training during commissioning or handover

Scalability & System Integration Barriers

Expanding from pilot to mass production requires modular, well-integrated solutions — yet many setups lack cohesion.
  • Difficulty transitioning from R&D to mass production scale
  • Fragmented equipment suppliers cause delays and integration issues
  • No unified control system or end-to-end turnkey engineering support
