As electric vehicle manufacturers pursue higher energy density, faster charging, and lower production costs, battery architecture has emerged as the critical frontier for competitive differentiation. For automotive engineering executives, battery technology investors, and supply chain strategists, the core challenge lies in transitioning from legacy cell formats to next-generation large-format cylindrical batteries that promise transformative performance gains but demand fundamentally new structural components. The 4680 battery format—with its unique tabless design, steel casing, and complex structural requirements—represents both the industry’s most promising pathway and its most demanding manufacturing hurdle. This report delivers a comprehensive strategic analysis of the global 4680 Battery Structure Components market, offering data-driven insights into technological evolution, production challenges, and the competitive dynamics shaping the future of EV battery manufacturing.
Based on current situation and impact historical analysis (2021-2025) and forecast calculations (2026-2032), this report provides a comprehensive analysis of the global 4680 Battery Structure Components market, including market size, share, demand, industry development status, and forecasts for the next few years. The global market for 4680 Battery Structure Components was estimated to be worth US$ 432 million in 2025 and is projected to reach US$ 1,549 million, growing at a CAGR of 20.3% from 2026 to 2032. The 4680 large cylindrical battery structural parts are quite different from the square battery structural parts, and are similar to the 2170 small cylindrical battery structural parts. There are three main changes between the 4680 battery structural parts and the 2170 battery structural parts. One is the thermal and electrical separation, the other is the addition of a current collecting plate, and the third is the increase in wall thickness. 4680 large cylindrical power battery structural parts use steel shells. For 4680 batteries, stamping and stretching are still the mainstream production process. However, due to changes in size and materials of 4680, the equipment needs to have greater stamping force and greater maximum drawing height, requiring increased processing capabilities of stamping equipment. The industry has high technical barriers, and the full-ear design doubles the complexity of cover welding; high concentration, Shenzhen Kedali Industry, as a leading enterprise, monopolizes the core process (precision stamping + laser welding), and new entrants face a technical verification cycle of more than 3 years. In 2023, the company has already started mass production and supply. Based on the performance and cost advantages of large cylindrical lithium batteries, many domestic and foreign battery manufacturers and new energy vehicle companies have laid out the technical research and development and production line construction of large cylindrical lithium batteries such as 4680. Among them, Tesla, as a key role in promoting the installation of large cylindrical batteries, will significantly increase the installed capacity of 4680 batteries for its own supply in 2024. At the same time, the BMW Group announced in February 2025 that BMW’s innovative large cylindrical batteries will be installed in 2025, and the new car will be equipped with BMW’s sixth eDrive electric drive system. Domestic and foreign 4680 large cylindrical projects have been successively increased in production and put into mass production. Combined with the breakthroughs and follow-up of large cylindrical battery technology routes by international car companies represented by Tesla and BMW, this may bring a new round of large cylindrical battery development opportunities and drive the growth of 4680 battery structural parts.

Beyond Cell Format: The Strategic Imperative of Structural Component Innovation
The extraordinary 20.3% CAGR, propelling the market from US$432 million in 2025 to US$1.549 billion by 2032, reflects a fundamental transformation in battery cell architecture. Our analysis reveals that the 4680 battery structure components market is experiencing hypergrowth driven by three converging forces: the industry-wide transition from prismatic and small-format cylindrical cells to large-format cylindrical architectures, the integration of tabless design for improved thermal management, and the imperative to achieve manufacturing scale for next-generation EV platforms.
What fundamentally distinguishes 4680 battery structure components from previous-generation components is their unique combination of steel casing for structural integrity, tabless electrode architecture that reduces internal resistance, and integrated current collection plates that simplify pack assembly. These engineering innovations enable higher energy density, faster charging capabilities, and improved thermal management—directly addressing the range and charging anxiety that remain barriers to EV adoption. However, these performance gains come with significant manufacturing complexity: the transition from 2170 to 4680 format requires stamping equipment with greater force capacity and increased maximum drawing height, while the tabless design doubles the complexity of cover welding operations.
Industry Dynamics: The Convergence of OEM Commitments and Manufacturing Scale
The past 12 months have witnessed structural shifts that every industry stakeholder must understand:
OEM Adoption Accelerates Beyond Tesla: While Tesla has been the primary catalyst for 4680 adoption, the BMW Group’s February 2025 announcement that its innovative large cylindrical batteries will enter production in 2025—powering vehicles equipped with the sixth-generation eDrive system—signals mainstream automotive acceptance. This commitment from a second major global automaker validates the 4680 format as an industry standard rather than a single-company initiative, creating confidence across the supply chain for capacity investments.
Production Scale Reaches Critical Mass: Following initial production ramp challenges, 4680 cell manufacturing capacity has reached meaningful scale. Tesla’s internal production lines achieved significant volume milestones in 2024, while battery manufacturers including CATL, LG Energy Solution, and Panasonic have accelerated their 4680 development programs. This scaling translates directly to demand for structural components, with each million cells requiring approximately 20-25 tons of precision-stamped components.
Technical Barriers Create Concentrated Supply Chain: The 4680 format imposes demanding technical requirements that limit the pool of qualified structural component suppliers. Steel shell stamping requires precision tooling and process control that takes years to develop. The full-ear cover welding operation demands laser welding capabilities with tight process windows to ensure electrical integrity and leak-free sealing. Industry data indicates that technical verification cycles for new entrants exceed three years, creating significant barriers to entry that reinforce the market leadership of established precision manufacturers.
Market Segmentation and Technical Differentiation
Our analysis segments the 4680 battery structure components market across three critical component types, each with distinct manufacturing requirements and value propositions:
Shell Components: The steel casing represents the largest segment by weight and a critical safety component. The transition from 2170 to 4680 format increases the required stamping depth from approximately 65mm to 80mm, requiring press equipment with higher tonnage capacity (typically 200-300 tons versus 80-100 tons for 2170 production). Wall thickness has increased from 0.2mm to 0.3mm to accommodate the larger diameter and provide structural rigidity. Manufacturers capable of consistent high-precision stamping across millions of units command significant market share.
Battery Cap Components: The cap assembly integrates the tabless electrode connection, venting mechanism, and electrical terminals. The tabless design—which eliminates the conventional welded tab by extending the electrode foil to the cell’s edge—requires fundamentally different cap welding processes. Laser welding precision must achieve consistent penetration depth across the full circumference, with any defect potentially causing cell failure. This complexity has driven concentration among suppliers with advanced laser welding capabilities.
Current Collecting Plates: A new component type introduced with the 4680 format, current collecting plates enable the tabless architecture by providing a continuous conductive path from the electrode roll to the external terminals. These plates require precision stamping of thin copper and aluminum foils, with dimensional tolerances measured in microns.
Competitive Landscape: Concentration and Barriers to Entry
The 4680 Battery Structure Components market is characterized by extreme concentration, with established leaders leveraging technical expertise and production scale:
Shenzhen Kedali Industry has emerged as the dominant player, with the company initiating mass production and supply in 2023. Kedali’s competitive advantage rests on its mastery of the core process combination—precision stamping integrated with automated laser welding—developed over years of serving the battery component market. The company’s early engagement with Tesla during the 4680 development phase provided critical process validation and production ramp experience that new entrants cannot easily replicate.
Zhenyu Technology, Wuxi Jinyang New Material, Zhongrui Electronic Technology, Jie Jing Precision, Ningbo Fangzheng, and Suzhou Dongshan Precision Manufacturing represent the next tier of suppliers, each with established capabilities in precision metal forming and existing relationships with battery manufacturers. These competitors are positioned to capture secondary sourcing opportunities as demand scales.
The three-year technical verification cycle creates a structural advantage for incumbent suppliers, as battery manufacturers and automotive OEMs prioritize proven quality and supply chain stability over cost savings from unproven entrants.
Technology Outlook: Scale, Automation, and Next-Generation Processes
Looking toward 2032, three technological developments will shape the competitive landscape:
High-Speed Stamping Lines: The transition to 4680 production is driving investment in stamping equipment capable of 200-300 strokes per minute, up from 100-150 strokes per minute for 2170 lines. This productivity improvement is essential to meet projected cell demand exceeding 100 GWh annually.
In-Line Laser Welding Integration: Fully automated production lines integrating stamping, cleaning, and laser welding operations reduce handling defects and improve yields. Manufacturers achieving 95%+ first-pass yield for cap welding will capture premium margins.
Alternative Material Development: While steel remains the dominant material for 4680 casings, research continues into stainless steel alloys and coated materials that could reduce weight or improve thermal conductivity without compromising safety.
Strategic Implications for Industry Stakeholders
For automotive engineering executives, battery technology investors, and supply chain strategists, the strategic implications are clear: the 4680 Battery Structure Components market is entering a period of accelerated growth driven by OEM adoption commitments, production scale achievement, and the fundamental performance advantages of large-format cylindrical cells. The projected growth to US$1.549 billion by 2032 reflects not just increasing unit volumes but a structural shift in battery manufacturing that will define the next generation of electric vehicles.
