Integral Technologies Announces Breakthrough Bipolar Battery

CANTON, MI -- Integral Technologies, Inc.'s wholly owned subsidiary ElectriPlast Corporation announces the company's invention of a patent pending, highly conductive plastic bipolar plate which will be developed into a lightweight, moldable and cost effective battery. This is another example of ElectriPlast's lightweighting benefits available to serve a new market vertical, batteries and power storage. Additionally, the ElectriPlast bipolar plate provides further benefits to manufacturers and end users, as it reduces steps and time in the manufacturing process, provides flexibility in the form factor of the battery, and is environmentally friendly.

"A view shared by many throughout the industry is that lead acid technology is reaching a sunset phase in the development cycle," says Doug Bathauer, President and Chief Executive Officer, Integral Technologies. "This is evident by the ongoing efforts to develop other technologies. While lithium ion, for example, is taking center stage, lead acid is still the 'tried-and-true' technology."

The worldwide market demand for lead-acid batteries was estimated to be $44.7B in 2014 and "projected to reach $58.5B by 2020," reports Future Market Insights. "Based on our high volume processing capability and elimination of the multiple components needed to assemble other material based plates, our conductive polymer based bipolar plate is very cost effective," says Bathauer. "Working within the industry and with the Integral Advisory Board, we are in the process of developing partnerships to realize the potential of this new market segment."

"ElectriPlast's unique properties allow us to tailor the conductivity and resistance of the bipolar plate substrate and subsequent surface treatment processes to create a low resistance bipolar plate as the contact to the active paste materials," says Slobodan "Bob" Pavlovic, VP Engineering of ElectriPlast Corporation who directs material research, product development and design initiatives for the company. "Our bipolar plate is created using a molding process enabling the creation of assembly interfaces that are suitable for multiple sealing solutions which vary from sonic/vibe welding to integrated seals compatible with battery environments. Mechanically robust, the polymer based structure of the bipolar plate allows for ease of handling and assembly as well as resistance to stresses in the battery environment."

"The molding process allows us to produce 3D shapes which allow the bipolar plate and integral structures to be produced in any desired form," said Mohammad Zeidan, CTO, ElectriPlast Corporation. "We are able to create reliable seals between the plates and enclosure to prevent electrolyte leaking."
