US Battery and Gridtential Energy partner
By Lindsey Anderson30 July 2020
US Battery and Gridtential Energy have formed a partnership to collaborate on Gridtential Energy’s Silicon Joule bipolar battery technology.
Under the terms of the agreement, US Battery and Gridtential Energy will industrialize bipolar plate pasting and curing processes. Additionally, Silicon Joule bipolar AGM (absorptive glass mat) batteries will be assembled and tested, using US Battery active material to drive further improvements in cycle life, energy density, battery efficiency, charging rates and manufacturability.
Silicon Joule bipolar technology enables an innovative class of advanced lead batteries with silicon at its core. According to the companies, the technology is a design-driven, low-cost, high-performance, patented energy storage solution that provides improved power density, cycle life, dynamic charge acceptance and wider temperature range, with up to 40 percent lower weight, while retaining full lead-battery recyclability. “This is all accomplished while leveraging existing technologies from mature industry supply chains – allowing rapid scaling through existing lead-battery infrastructure,” the companies said in a statement.
US Battery also noted that as it achieves new performance milestones, the company will be “well positioned to manufacture and distribute industry leading bipolar AGM products to the market.”
Terry Agrelius, CEO of US Battery, commented, “US Battery hopes to combine the current advantages of premium deep cycle, lead acid battery cycle life that provides low cost per watt-hour over the life of the battery with the advantages of high power density and increased cycle life offered by the Gridtential Energy Silicon Joule bipolar battery technology. This combination could provide the improvements necessary for US Battery to better compete with the advanced battery technologies currently on the market and proposed for future market development while maintaining the safety and recyclability of lead-based battery technologies.”
John Barton, CEO, Gridtential Energy, said, “US Battery is an ideal partner for Gridtential. Leapfrog product innovation often starts with fresh thinking on how to best utilize core company strengths to make a disruptive move. Gridtential offers a better way to build a battery with modern materials from the solar industry. The leadership at US Battery is taking a smart approach, leveraging Silicon Joule technology with their organizational expertise in electrochemistry and battery manufacturing to create a new class of high-performance products. Gridtential is proud to work with partners taking bold steps to accelerate advancements in the industry.”
