Cylindrical Batteries

Cylindrical lithium-ion – and to a lesser degree sodium-ion – batteries are essential to today’s high-performance technologies, powering everything from electric vehicles (EVs) and medical devices to power tools and energy storage systems. To meet growing demand, manufacturers need advanced, reliable, and scalable production technologies.

Key Technologies for every critical step in cylindrical battery manufacturing:

  • Battery Tab Welding / Internal Connections – High precision laser and resistance welds for tab-to-cell and cell-to-cell connections, and battery pack assembly
  • Laser Seam Welding – Hermetic sealing of cylindrical battery cans to provide structural integrity and moisture resistance

Prismatic Batteries

Prismatic lithium-ion battery cells meet the growing demand for compact, flat form factors. Designed with stacked internal layers—rather than traditional jelly roll configurations—prismatic cells maximize space efficiency, making them ideal for slim devices such as smartphones, tablets, and low-profile laptops.

Prismatic cells are also available in large-format versions, typically housed in welded aluminum enclosures. These rugged, high-capacity cells are widely used in hybrid and electric vehicles, where reliability, structural integrity, and thermal stability are essential.

Ultracapacitor Batteries

Ultracapacitors, also known as supercapacitors, offer a high-performance energy storage solution with longer life, faster charge times, and greater efficiency than conventional batteries. Unlike traditional lithium-ion batteries, ultracapacitors store energy in an electric field rather than through a chemical reaction, enabling rapid charge/discharge cycles and more than one million life cycles.

They are also significantly lighter in weight, contain fewer toxic materials, and exhibit extremely low internal resistance, allowing them to operate at nearly 100% energy efficiency.
