With the rapid development of the global new energy industry, lithium iron phosphate (LFP) has become one of the important technical routes for power batteries, also raising higher requirements for smart warehousing. From clean control and production continuity to digital collaboration, smart warehousing is gradually becoming an important infrastructure for new energy battery manufacturing.

Relying on years of experience in new energy lithium battery projects, ROBOtech has developed smart warehousing solutions covering application scenarios such as lithium battery materials, cell manufacturing, formation and grading, module PACK, and energy storage, providing full-process intelligent logistics support for enterprises in the lithium battery industry chain. The Korean PNT LFP material automated warehouse project is another representative practice of ROBOtech's new energy smart warehousing solutions entering the overseas market.

Layout of the LFP material industry, PNT's warehousing upgrade practice

PNT is a South Korean listed secondary battery equipment company, which has long been deeply involved in the field of Roll-to-Roll (R2R) precision equipment and possesses rich technical accumulation in the research and development and manufacturing of lithium battery equipment. In recent years, the company has continuously expanded its layout in the new energy industry, building an LFP cathode material production base in Gumi, South Korea, further improving the layout of the secondary battery industry chain.

As a company engaged in the research and development of automation equipment for a long time, PNT has strict requirements for equipment performance, system stability, and intelligence level. In this project, PNT chose Huso Micro-Nano Technology to be responsible for overall project integration, ROBOtech to provide the core smart warehousing equipment, control systems, and software platforms, jointly creating an intelligent warehousing system that covers the entire process from raw material storage, production distribution, finished product buffering to outbound shipment.

Dual-warehouse collaboration, creating an intelligent storage solution for LFP materials

Focusing on the production process requirements of LFP materials, Robotel plans to build an automated three-dimensional warehousing system with coordinated operation of raw material and finished product warehouses, with a total of 2,496 storage positions, including 1,360 in the raw material warehouse and 1,136 in the finished product warehouse.

The project is equipped with 4 ROBOtech Black Panther series twin-column stackers. The stacker in the raw material warehouse has a total height of about 22 meters, while the stacker in the finished product warehouse has a total height of about 21.6 meters. The stacker has a maximum operating speed of 100 m/min, positioning accuracy of ±5 mm, and fork positioning accuracy of ±3 mm, achieving high-precision storage and retrieval while ensuring operational efficiency.

The system adopts a dual-layer architecture with a WMS warehouse management system and a WCS equipment control system, seamlessly interfacing with ERP and MES systems to achieve real-time coordination of logistics, information flow, and production flow, building an efficient, stable, and traceable intelligent logistics system for customers.

For lithium battery material manufacturing enterprises, an intelligent warehousing system not only fulfills storage functions but also serves as crucial infrastructure to ensure continuous production operation and improve manufacturing efficiency. Roboteck provides customers with an intelligent warehousing solution covering the entire warehouse lifecycle through an integrated design of core equipment, software platforms, and control systems.

Deeply understand the characteristics of materials and processes, and strengthen the defense line of clean production

For intelligent warehousing of lithium battery materials, the core challenge is not only the equipment parameters but also the deep adaptation to the characteristics of the production process. Especially for LFP cathode material production, cleanliness is a core indicator throughout the entire process and a key defense line that the warehousing system must maintain.

In response to the strict requirements for metal foreign object control in LFP materials, Roboteq implements multiple layers of protection from material selection and manufacturing processes to clean management: sensitive metal components such as copper, zinc, and silver are wrapped and isolated; argon arc welding is used in manufacturing, and weld seams are polished smooth without burrs, while distribution cabinets use zinc-free processes; at the same time, four sets of air showers are installed. These measures reduce the risk of metal foreign object introduction from the source to the process in multiple dimensions, providing a cleaner and safer storage environment for LFP material production.

High-reliability design provides a solid guarantee for continuous production

Lithium battery material factories usually maintain continuous production, and the stability of the storage system is directly related to the operational efficiency of the entire production line. 

For storage applications over 20 meters high, ROBOtech has built a multiple safety protection system covering derailment prevention, top impact prevention, safety door interlocks, and more. Among them, the mechanical speed-limiting anti-fall device can automatically lock through its mechanical structure even in extreme conditions such as wire rope breakage, providing reliable protection for the long-term stable operation of the equipment.

Having been deeply involved in the lithium battery field for many years, ROBOtech, leveraging its integrated capabilities of core equipment and self-developed software systems, has extensively served leading global clients in the industry chain, including CATL, BYD, CALB, Sunwoda, BTR, and Panasonic.

The South Korea PNT project is another representative case of ROBOtech’s overseas deliveries. The project’s hardware and software products meet the Korean KCS certification requirements, fully demonstrating ROBOtech’s ability to adapt its products to overseas market entry requirements and its international delivery capabilities. In the future, the company will continue to strengthen its technology and scenario adaptation capabilities, providing global customers with safe, efficient, and intelligent warehousing solutions.
