Comparison of Conventional Ni-MH Battery and GIGACELL

Benefits of the GIGACELL Structure

    Cooling Fan
  • Powerful and efficient cooling enables charging / discharging at high amperages.
  • Non-welded
  • With no welding processes during its production, disassembly and recycling processes are facilitated.
  • Fully Sealed
  • The GIGACELL is fully sealed, needing no maintenance.


GIGACELL modules are composed of individual cells that are connected in series by their cell walls, with the front and rear surfaces becoming positive and negative electrodes, forming the bipolar structure. The thin cell walls provide a large cross-sectional area that minimizes energy loss, which occurs when the cells are connected. Therefore, the large capacities of modules can be accomplished by increasing the number of cells connected in the bipolar structure.

3D Design

Inside each cell, pre-formed strips of positive and negative electrodes are inserted into the two sides of a pleat-folded separator. Increasing the three dimensional elements of the pre-formed strips (height, width and quantity) can easily expand the capacity of the battery.

Battery Monitoring System

Functions: Calculates SOC, takes measurements of cell voltage, battery temperature and battery internal pressure, and outputs warnings as necessary.
