The integration of China's metal components industry and energy storage industry
”
The integration of China's metal components industry and energy storage industry has formed a deep collaborative system centered on lightweight materials, high safety standards, and system integration manufacturing. Aluminum alloy, with its excellent thermal conductivity and weight reduction advantages, has become the core material for battery shells, liquid cooled plates, and frames, supporting CTP/CTC highly integrated architectures and reducing individual weight by 15% -20%; 316L stainless steel and titanium alloy are widely used as connectors and pipelines in highly corrosive environments, meeting the strict requirements of GB 44240-2024 mandatory safety standards for thermal runaway protection, salt spray resistance, and pressure sealing. Leading companies such as Kodali and Ningde Dongheng are deeply bound to Ningde Times, with energy storage structural component orders exceeding 20 billion yuan in 2025, accounting for over 20% of their revenue. Laser welding and integrated die-casting technology have reduced the defect rate to below 0.03%, and the airtightness yield of liquid cooled plates has reached 99.99%, promoting the cost proportion of structural components to remain stable in the range of 12% -25% of energy storage systems. With the outbreak of independent energy storage and industrial and commercial projects, metal components are upgrading from 'accessories' to 'safety architecture definers', supporting China's energy storage system to achieve dual output of technical standards and manufacturing capabilities in the global market.
