The Asian secondary battery manufacturing industry is experiencing significant expansion, fueled by the rising demand for portable electronics, electric vehicles, and renewable energy storage systems. A critical element in secondary battery electrode production is the slot die, an integral component of coating machinery, which enables precise electrode slurry application onto current collector (foil).

However, battery manufacturers face challenges in improving productivity due to issues such as coating uniformity, process variation, clogging, maintenance, and material compatibility during the use of slot die.

GI Tech, a prominent slot die manufacturer, proactively addresses these issues by leveraging state-of-the-art equipment and sophisticated production methods to create slot die heads for use in the coating process. GI Tech possesses a key technology that allows slurry to be coated evenly on electrode while complying with a cost-effective production system with high precision parts (slot die). This innovative approach highlights GI Tech’s commitment to overcoming industry challenges and bolstering the secondary battery manufacturing sector.

“We take pride in our ability to quickly produce competitive products in order to meet customer demands without sacrificing quality or efficiency,” says Lee In Young, chairman of GI Tech.

The firm provides a comprehensive suite of services, including the manufacturing and repair of slot dies and slit nozzles, tailored to meet the specific requirements of secondary batteries, hydrogen batteries, and display production processes. It also designs, manufactures, installs and services the production/manufacturing equipment related to these core products.

Committed to continuous improvement and expansion of its technological capabilities, GI Tech invests in research and development initiatives to devise advanced solutions for precision machining. In order to deliver exceptional service to its clientele, the company has bolstered its quality management systems, acquiring both domestic and international certifications for quality control. By implementing stringent inspections and tests, GI Tech ensures that its products align with customer expectations while optimizing defect rates and expediting turnaround times. This multifaceted strategy positions GI Tech as a formidable global competitor.

The firm endeavors to assist its customers to seamlessly achieve their production objectives by designing and manufacturing bespoke slot dies. Numerous clients utilize hundreds of slot dies in their production lines to manufacture secondary batteries, resulting in challenges such as frequent replacements and escalating costs due to high production volumes. GI Tech has tackled these issues by enhancing productivity across the entire production line and introducing an innovative slot die variant that extends replacement intervals compared to conventional models. The firm has also established a system to improve slot die management by predicting future usage and scheduling replacements in advance, leading to increased performance rates and reduced costs associated with regular slot die replacements.

As the conventional wet electrode process in battery production grapples with high energy consumption and the emission of volatile organic compounds (VOCs), GI Tech is committed to addressing these concerns by promoting a dry electrode process for battery manufacturing. This method offers several benefits, such as raw material cost savings, process simplification, and enhanced energy density.

In 2022, GI Tech recognized the impending technological shift and embarked on the development of the groundbreaking dry electrode process. The company actively seeks strategic collaborations with other organizations to advance this technology, exemplified by a memorandum of understanding (MOU) with GRINERGY—a prominent LTO battery manufacturer—to expedite development. The firm aims to finalize the dry electrode process by 2023.

GI Tech achieved a notable milestone in 2022, reporting record sales of USD 30,335,000 (as of 03/30 currency standard), which represents a 103 percent increase compared to the previous year and projecting continued growth. The company has adapted to the evolving landscape through technological innovation and investment in human resources, addressing industry trends such as green policies and advancements in secondary battery technology.
