Company Overview - Jiujiang Defu Technology Co., Ltd. (referred to as "Defu Technology") was established in 1985 and is headquartered in Jiujiang, Jiangxi Province, China. The company was listed on the Shenzhen Stock Exchange's Growth Enterprise Market in 2023, with stock code: 301511. Defu Technology has been deeply engaged in the copper foil industry for 40 years, focusing on the research, production, and sales of high-end electrolytic copper foil, with an annual production capacity of 191,000 tons, ranking first globally. The lithium battery copper foil products range from 3.5 to 10 micrometers, primarily used in downstream power batteries, energy storage, and digital fields. The electronic circuit copper foil products range from 10 to 210 micrometers, widely used in downstream printed circuit boards and terminal communications, consumer electronics, and automotive fields [1]. Energy Efficiency Initiatives - Defu Technology has implemented a copper dissolution waste heat utilization project across its production bases, modifying the copper dissolution system to utilize workshop cooling water waste heat to produce high-temperature hot water, thereby replacing natural gas usage. The annual natural gas consumption for the copper dissolution process is approximately 2 million cubic meters, with a target to achieve zero natural gas consumption by July 2025. The self-heat exchange modification of the copper dissolution system has resulted in a 60 kWh/t reduction in electricity consumption per unit product [2]. - The waste heat generated from the copper dissolution system is utilized in various ways, including heating air conditioning systems at the Jiujiang production base, with a total annual waste heat utilization of 11.155 million kWh. The Lanzhou production base uses waste heat to replace municipal heating in winter, providing heating for office buildings, dormitories, and auxiliary production facilities, reducing external heating purchases by approximately 6.3 million kWh, with total annual waste heat utilization exceeding 25 million kWh [2]. Smart Technology Integration - Defu Technology has upgraded its refrigeration station with AI technology, allowing real-time adjustments of various parameters of the cooling water units. The AI system collects big data and uses built-in optimization algorithms to issue commands for automatic adjustments of the cooling water units, pumps, and cooling tower fans. This upgrade has transitioned the refrigeration system from manual control to fully automated and efficient smart control, saving approximately 650,000 kWh of electricity annually for a single workshop [3]. - The company has also improved the efficiency of traditional switch rectifiers by replacing the original rectifier units with silicon carbide modules, reducing power conversion losses and achieving an average decrease in electricity consumption of about 200 kWh/t per unit product [3]. Equipment Modernization - Defu Technology has conducted energy-saving modifications on old workshop equipment by replacing traditional frequency pumps with permanent magnet motor variable frequency drives and using high-efficiency air suspension energy-saving fans instead of screw fans, resulting in a total annual electricity savings of 2.23 million kWh [4]. - Experts have noted that through waste heat recovery and improved rectifier efficiency, the company has significantly reduced electricity consumption per unit product, showcasing its commitment to energy conservation and resource recycling, thereby establishing a new benchmark for green production [4].
