As a trailblazer in China’s power battery industry, Jiangsu Zhengli New Energy Battery Technology Co., Ltd. adheres to aviation-grade standards across its entire production workflow. The company recently placed a bulk order for KQET-5018STG airborne particle counters from Suzhou Kangqi Environmental Technology Co., Ltd. for its newly built intelligent energy battery workshop. Delivering accurate environmental monitoring, the equipment empowers high-quality battery manufacturing and substantially strengthens the company’s cleanroom control capabilities throughout production.

Lithium battery manufacturing demands extremely rigorous cleanroom conditions. Critical processes including electrode slitting, cell stacking and electrolyte injection must be carried out within controlled clean spaces. Micro dust particles can not only trigger cell short circuits and performance degradation but also pose severe safety hazards. The newly equipped workshop of Zhengli New Energy specializes in mass production of lithium iron phosphate and ternary lithium batteries, complying with national standard GB 51377-2019. Its core zones are required to maintain ISO Class 6 to ISO Class 7 cleanliness, calling for ultra-high precision monitoring of dust particles 0.2μm and larger. The KQET-5018STG particle counter from Kangqi is purpose-built to match such stringent requirements.

A national high-tech enterprise and a drafting participant of national standards for cleanroom testing, Kangqi Environmental stands out with the robust performance of its KQET-5018STG model. Fitted with a long-life semiconductor laser diode imported from Japan, the instrument accurately detects particles across full-size channels covering 0.2μm, 0.5μm up to 10μm, with indication errors kept within qualified limits—fully meeting the workshop’s need to track ultrafine dust.

Boasting a compact 304 stainless steel housing for easy installation, the unit can be seamlessly integrated into Zhengli New Energy’s automated production lines. Its built-in vacuum source enables stable low-vibration, low-noise operation with a 3-year service life. Tailored to the client’s intelligent manufacturing architecture, the KQET-5018STG features comprehensive smart functions. Equipped with a 4.3-inch touchscreen for on-site startup, shutdown and parameter configuration, it connects to the workshop’s AI management system via RS485 communication ports to enable remote monitoring and real-time data synchronization. This supports Zhengli New Energy in building a closed-loop quality control framework of “Sensing – Decision-Making – Execution”. The integrated audio-visual alarm instantly alerts operators to excessive particle concentrations, while automatic flow regulation guarantees precise, consistent sampling data to guide timely cleanroom adjustment.

This collaboration stems from a perfect alignment of the two parties’ technical philosophies. Zhengli New Energy has an urgent demand for digitalized environmental production control, and the KQET-5018STG’s built-in functions including USB data export and calibration expiration reminders support full-lifecycle data archiving to satisfy complete traceability requirements for battery production. As a trusted cleanroom equipment supplier serving industry giants such as BYD and Camel Group, Kangqi Environmental will also provide customized calibration and maintenance services for Zhengli New Energy to sustain long-term stable equipment performance.
