Bipolar

The revolutionary bipolar battery design is based on a sealed, flat, lightweight wafer cell. Each cell has positive and negative electrodes and separator material. Sealed contact faces on the surface of the cell make electrical contact between the positive and negative electrodes of adjacent cells. Stacking individual cells together in a highly compressed, low impedance series creates a multi-cell battery.

The bipolar design, with superior space and energy storage efficiency, results in batteries with up to 50 percent higher power, 30 percent better volume, and a longer life — at a lower cost than conventional monopolar batteries.

Chief characteristics for advanced applications include:

• Lightweight, compact, high performance, energy efficient, reliable, tolerance to abuse, and adaptable to multiple chemistries.
  
• Eliminates conventional terminals, tabs, current collectors and cell containers, reducing weight, volume and the cost of the finished battery.
  
• Eliminates the need for highly toxic materials, making the batteries safer for the environment, safer to manufacture and use, and designed or sealed, maintenance free operation.
  
• Thermal management is incorporated into each wafer cell, ensuring that each cell has the same thermal map as the one adjacent to it. This allows high-density packaging while improving cycle life and a high performance.
  
• Eliminates components normally required at the headspace, making it possible to create a bipolar stack made up of many, many cells, with electrical connections at the end of the series stack for virtually unlimited scalability.
  
• The patented manufacturing process for bipolar technology includes raw material treatment resulting in improved performance, continuous production of positive and negative electrodes, with processes unique to the bipolar design, and customized cell packaging processes. These processes result in low-cost manufacturing techniques.
