Battery Companies Team On Silicon Joule Technology
By Mike Brezonick04 August 2020
Gridtential Energy and US Battery, a global supplier of flooded lead acid (FLA) deep cycle batteries, announced that they have entered into a formal agreement to collaborate on Gridential’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 absorptive glass mat (AGM) 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. As US Battery achieves new performance milestones, the company will be positioned to manufacture and distribute bipolar AGM products to the market.
Silicon Joule bipolar technology enables a new class of advanced lead batteries with silicon at its core. It 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, the companies said. It also offers up to 40% 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.
Combining Battery Advantages
“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,” said Terry Agrelius, CEO of US Battery. “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.”
US Battery provides FLA and AGM deep cycle batteries for golf cars, NEV (neighborhood EV) & LSEV (low speed EV), industrial electric vehicles, as well as renewable energy and energy storage battery markets.
“US Battery is an ideal partner for Gridtential,” said John Barton, CEO, Gridtential Energy. “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.”
