I. Modular Cleanroom Design

High Cleanliness

A modular cleanroom must ensure that the air cleanliness level within the workshop meets production requirements, preventing dust, particles, and other contaminants from adversely affecting lithium-ion battery manufacturing. Typically, an air cleanliness class of ISO Class 7 or higher is required. This necessitates the installation of high-efficiency air purification systems, along with regular cleaning and maintenance.

Temperature and Humidity Control

Lithium-ion battery production has strict requirements for temperature and humidity. The modular cleanroom should be able to precisely control both. Generally, the temperature should be maintained at 20°C–25°C, and the relative humidity at 30%–60% (note: certain specific processes, such as electrolyte filling, may require even lower humidity levels and should be adjusted according to actual process requirements). This requires accurate temperature and humidity control systems, including air conditioning as well as humidification and dehumidification equipment.

Anti-Static Measures

During lithium-ion battery manufacturing, it is essential to prevent electrostatic discharge (ESD). Modular cleanrooms should incorporate anti-static measures, such as ESD flooring and anti-static wall materials, to avoid potential damage to batteries and production equipment caused by static electricity.

Modular Design

Modular cleanrooms allow for rapid construction, adjustment, and expansion. Space can be flexibly configured according to production needs, improving efficiency and operational flexibility. In addition, modular designs facilitate future production line upgrades and workshop renovations.

II.Functional Zoning and Airflow Organization

Functional Zoning

The workshop should be divided into areas such as raw material preparation, electrode manufacturing, cell assembly, testing, and packaging. Buffer zones should be set up between different areas to reduce cross-contamination and ensure an orderly production process.

Airflow Organization

A well-designed airflow system is required to ensure smooth air movement within the cleanroom, avoiding dead zones and turbulence. A top-supply, bottom-return airflow pattern is commonly used, where clean air is supplied from the ceiling, passes over the work area, and is exhausted through the floor. This effectively controls particle concentration and maintains the required cleanliness level.

III. Material Selection and Construction

Walls and Ceilings

Dust-free and easy-to-clean materials should be used, such as color steel panels, hand-made rock wool sandwich panels, and hand-made magnesium-oxide hollow sandwich panels. These materials offer good airtightness and insulation performance while effectively preventing dust and contaminants from adhering.

Flooring

The floor should be made of wear-resistant, corrosion-resistant, and easy-to-clean materials, such as epoxy self-leveling flooring. This type of flooring can effectively resist chemical corrosion and static electricity buildup, providing a stable production environment.

 Doors, Windows, and Viewing Panels

Doors should be formed steel cleanroom doors, while windows should use tempered glass or large insulated glass viewing panels to ensure airtightness and maintain cleanroom cleanliness.

IV. Equipment Selection and Layout

Air Purification Equipment

Primary, medium, and high-efficiency air filters should be used and maintained regularly. Dehumidification units and humidification equipment should also be configured according to production requirements.

Production Equipment

Equipment should offer high precision, high stability, and high efficiency, and be easy to clean, disinfect, and maintain. Equipment layout should be planned based on the production process flow and equipment characteristics to ensure smooth and efficient operations.

V. Intelligent Management and Safety Protection

Intelligent Management

An intelligent monitoring system should be installed to monitor environmental parameters and equipment operating status in real time. Through data analysis, management efficiency and production safety can be improved. Intelligent lighting and air-conditioning systems should also be implemented to automatically adjust based on actual demand and personnel activity, reducing energy consumption.

Safety Protection

A comprehensive safety management system should be established, including personnel training, equipment operation procedures, and emergency response plans. Safety facilities such as firewalls and explosion-proof doors should be installed, and all electrical systems and equipment must meet explosion-proof standards. Fire alarm systems and fire-fighting equipment should also be provided to ensure prompt response in the event of an emergency.

What is the features of Modular Cleanrooms ?

Cost-Effective: Modular design significantly reduces production and installation costs. Materials are reusable, minimizing resource waste and environmental pollution.

Flexible Assembly: Individual modules can be adjusted and combined according to actual needs, meeting the requirements of different scenarios and applications.

True Modularity: Each section is an independent module, making transportation, installation, and post-installation maintenance easier, while improving construction efficiency and flexibility.

Enhanced Performance: Advanced materials and technologies—such as large double-layer insulated glass viewing windows with black borders—are used to improve both appearance and performance.

Temperature & Humidity Control: Constant temperature and humidity air-conditioning systems or compact ceiling-mounted air conditioners can be selected according to process requirements.

Pressure Differential Control: A specific pressure differential must be maintained between the cleanroom and the outdoor environment, as well as between cleanrooms of different cleanliness classes, to prevent backflow of contaminated air.

High Mobility: Casters can be added as required, enabling easy relocation. This allows the cleanroom to adapt to changes in factory layout and supports rapid plant setup, small-batch production, multi-product manufacturing, and flexible production needs.

Ultra-Low Dew Point & Low Humidity: Ultra-low dew point, low-humidity solutions can be provided according to customer-specific production process requirements.

What is the advantages of Modular Cleanrooms ?

High Efficiency: Modular construction improves manufacturing and installation efficiency, enabling rapid enhancement of local cleanliness levels.

Flexibility: Cleanrooms can be quickly reconfigured or expanded to accommodate different scales and types of production or research activities.

Environmental Sustainability: Up to 98% of materials are reusable, reducing waste and environmental impact and aligning with sustainable development principles.

Intelligent Control: Modular cleanrooms are equipped with intelligent control systems that monitor and adjust environmental parameters in real time, improving operational efficiency and management effectiveness.

What is the Applications of Modular Cleanrooms ?

Fast modular cleanrooms are widely used in industries and environments requiring high cleanliness levels, including optoelectronics, electronics, semiconductors, photovoltaics, biopharmaceuticals, medical devices, laboratories, hospital operating rooms, cell culture, lithium-ion batteries, new energy, precision instruments, food, health supplements, packaging, glass, printed circuit boards (PCBs), LCM, touch screens, LEDs, cameras, and electronic assembly areas.
