Industry Dynamics: Capacity Expansion And Technological Breakthroughs

Recently, a large domestic material company announced that it would invest in the construction of a 5,000-ton nickel-plated busbar production line to support the IGBT heat dissipation module production project. The project uses a fully enclosed negative pressure collection system to treat exhaust gas, and combines multi-stage chemical precipitation technology to treat nickel-containing wastewater to ensure that the discharge complies with the "Electroplating Pollutant Emission Standards", marking a further improvement in the industry's environmental protection standards. At the same time, the project introduces an intelligent production line to achieve full process automation from copper rod extrusion to finished product packaging. The annual production capacity is expected to meet the rapid growth demand in the new energy vehicle and energy storage fields.

As power batteries develop towards high energy density, pre-nickel-plated steel strips have become a key material for cylindrical batteries. Domestic companies optimize the thermal diffusion process to form a Fe-Ni alloy interface between the nickel layer and the steel matrix, significantly improving adhesion and corrosion resistance. Data shows that pre-nickel-plated materials perform well in salt spray tests, with no rust for 60 minutes, meeting the service life requirements of power batteries for more than 10 years. At present, relevant enterprises are accelerating the mass production verification of pre-nickel-plated steel strips for 4680 batteries, and it is expected that large-scale supply will be achieved in the second half of 2024.

To cope with the problem of insufficient supporting facilities in the surface treatment industry, governments in many places plan to build specialized parks. For example, a central province has built a green intelligent surface treatment industrial park integrating electroplating, coating, and conversion film, with a centralized wastewater treatment center that can treat multiple types of industrial wastewater such as chrome plating and nickel plating. Through the "unified pollution control and shared facilities" model, the park reduces the environmental protection costs of small and medium-sized enterprises, attracts the agglomeration of industries such as automotive Nickel Plated Bus Bars, and electronic information, and forms an industrial ecology with an annual output value of over 10 billion yuan.

As a high-end conductive material, the technological evolution of nickel-plated Copper Bus Bars is closely related to market demand. With the rapid development of new energy, intelligent equipment, and other fields, the industry will continue to upgrade to high reliability and low pollution. Enterprises need to increase R&D investment, optimize process routes, actively respond to environmental protection policies, and seize the opportunities for industrial cluster development to cope with future market competition and technological changes.
