CELL TYPES


Flexible solutions thanks to a wide variety of designs

The core of a battery system are lithium-ion cells, which Voltabox further enhances based on a unique module kit approach. Voltabox sees itself as "cell agnostic", drawing from a wide variety of cells that were previously meticulously characterized and evaluated. Voltabox's product range includes cylindrical, prismatic, or pouch cells and each design has its own specific characteristics.

  • Cylindrical cells

    Type 26650

    This is a standardized cylindrical design, where the type designation describes the outer cell dimensions: 26 mm diameter, 65 mm height. Cylindrical cells have a mostly solid, metallic outer shell in which the active layers are inserted as wraps around the inner electrode. In this type of battery, the poles (plus and minus) are located opposite each other. 

    This design typically is available with different cell chemistries. For LFP-based cells: the use of so-called high-energy variants (HE) is ideal if great ranges are required. High-power cells (HP) are commonly used if high performance is required.

  • Pouch cells

    In pouch cells, the stacked or folded active layers are enclosed by a flexible outer foil, most commonly made of aluminum. The battery poles (so-called "taps") are usually thin metallic conductors guided toward the outside. Due to the lack of solid outer casings, pouch cells can be produced in low thicknesses with a low specific weight in almost any size. Their flat shape offers good heat dissipation options.

    This design typically is available with different cell chemistries. For NMC-based cells: the use of so-called high-energy variants (HE) is ideal if great ranges are required. High-power cells (HP) are commonly used if high performance is required.

  • Prismatic cells

    Prismatic cells (also known as flat cells) have a solid, metallic casing in a cubic form ("hardcase"). The battery poles are typically arranged on the upper flat side on the outer edges. The large surface of this design allows for good dissipation of heat.

    Prismatic cells are available in all common battery chemistries: LFP, NMC, and LTO. For the LFP and NMC variants: the use of so-called high-energy variants (HE) is ideal if great ranges are required. High-power cells (HP) are commonly used if high performance is required.
