Strategic Cooperation! Jinan Winner Winner2006A Particle Size Analyzer Adopted by Chaowei Power to Empower Accurate Testing of Battery Materials

The core product of Jinan Winner Particle Instruments Co., Ltd. (hereinafter referred to as "Jinan Winner") — Winner2006A Intelligent Laser Particle Size Analyzer — has successfully settled in Chaowei Power Co., Ltd. (hereinafter referred to as "Chaowei Power"). It will provide high-precision particle size distribution detection support for the entire production process of Chaowei's battery materials, helping to improve core battery performance and product stability. This cooperation not only reflects Chaowei Power's high recognition of Jinan Winner's technical strength but also marks another important case of domestic particle size analyzers being applied in the new energy battery field.

As a leading enterprise in China's new energy battery industry, Chaowei Power has deep roots in power batteries, energy storage batteries and other fields for many years, and has strict standards for the performance control of battery materials. The particle size distribution of battery materials directly affects electrode compaction density, ion diffusion rate and cycle life — for example, the particle size uniformity of lithium iron phosphate cathode materials significantly influences battery capacity and low-temperature discharge performance, while the agglomeration control of graphite anode materials is related to the optimization of battery rate performance. After multiple rounds of rigorous testing and comparison, Chaowei Power ultimately chose Jinan Winner's Winner2006A Particle Size Analyzer, precisely valuing its accuracy, stability and adaptability in battery material testing scenarios.

As a star product of Jinan Winner, the Winner2006A adopts the classic Mie scattering theory, equipped with a dual-beam design of He-Ne laser (632.8nm) and semiconductor auxiliary laser (532nm), achieving an ultra-wide measurement range of 0.01μm-1000μm. It perfectly meets the full-dimensional detection needs of the battery industry, from nano-scale additives to micro-scale electrode materials. The instrument is equipped with 90 high-sensitivity detection channels, combined with an automatic optical path calibration system, ensuring that the accuracy error and repeatability error of D50 value are both less than 0.5%, far exceeding the industry average. The data accuracy is fully compliant with international and national standards such as ISO 13320 and GB/T 19077.1. Addressing the pain points of battery slurry being prone to agglomeration and difficult to disperse, the instrument is built with a 40kHz ultrasonic dispersion module and a 0-3000rpm variable-speed stirring system, which can effectively break particle agglomeration, truly restore the intrinsic particle size distribution of materials, and provide reliable data support for Chaowei Power's process optimization.

In battery material production, the Winner2006A will run through key links such as precursor preparation, ball milling process and slurry mixing: by accurately measuring the particle size of lithium iron phosphate precursor, it helps optimize sintering process parameters; real-time monitoring of the dispersion state of electrode slurry avoids the risk of battery short circuit caused by large-sized agglomerates; comparing the particle size consistency of different batches of materials ensures the stability of finished battery performance. Its supported manual/automatic dual-operation mode and multi-dimensional data analysis functions (including free distribution, log-normal distribution, mesh number classification, etc.) can meet Chaowei Power's diverse needs from R&D experiments to production line quality control, greatly improving detection efficiency and data utilization.

With more than 20 years of experience in the particle analysis instrument field, Jinan Winner has built a comprehensive product portfolio covering laser particle size analyzers, zeta potential analyzers and other series through continuous R&D investment and technological innovation. It has served more than 5,000 customers and maintained a top-three market share for five consecutive years. The company invests 12% of its annual revenue in R&D and has obtained 47 patented technologies. Its laser particle size analyzers are renowned for high precision and stability, and are widely used in more than 30 industries including new energy, building materials and pharmaceuticals. This cooperation with Chaowei Power is a precise connection between Jinan Winner's technological achievements and the needs of the new energy industry, and also provides a strong example for the replacement of domestic instruments in the high-end manufacturing field.

In the future, Jinan Winner will continue to focus on "Precise Measurement, Innovative Service" as its core, relying on 12 national technical service centers and a 7×24-hour response mechanism to provide comprehensive technical support and after-sales service for Chaowei Power. Meanwhile, the company will focus on the testing pain points of the new energy battery industry, continuously iterate product technologies, launch customized solutions more in line with industry needs, help more battery enterprises enhance their core competitiveness, and promote the high-quality development of China's new energy industry.
