Johnson Controls licenses rugged bipolar battery technology

January 20, 2017 // By Nick Flaherty
Johnson Controls has licensed technology to build lead acid batteries with improved vibration durability, greater cycle-life performance and a simplified approach to higher-voltage applications.

The GreenSeal technology has been developed by US company Advanced Battery Concepts (ABC) of Michigan for energy storage applications.

"Our GreenSeal technology considerably simplifies manufacturing processes in lead-acid bi-polar batteries while simultaneously improving battery performance," said DrEdward Shaffer, CEO and Founder of Advanced Battery Concepts.  "We are very proud to work with Johnson Controls, the world's leading automotive battery manufacturer, as we continue to develop and commercialize these products."

In bi-polar batteries, electrical conduction occurs through the same plate, rather than the strap used in conventional lead-acid batteries to transfer positive and negative electrons between plates.

First developed by Nobel laureate Pyotr Kapitsa in 1924, bipolar designs differ from traditional prismatic designs by replacing the heavy metal grids connected by a top-level, cast-on-strap with a conductive plate having positive material on one side and negative material on the other side. ABC was the the first company to successfully design a bipolar lead acid battery and develop and implement a commercially viable manufacturing process for such batteries. It is working with existing lead acid battery producers and engaging licensees such as Johnson Controls to develop the commercial potential of its technology, as well as on-going production of batteries and additional research from its Battery Research & Engineering Development Centre in Michigan.
