Accelerates Silicon Joule™ commercialization for advanced high power battery designs

SANTA CLARA, Calif. – January 12, 2017 – Gridtential Inc., an innovator in low-cost, high-performance energy storage technologies, today announced it has completed a $6 million fundraise with strategic investors from some of the world’s largest battery suppliers and distributors. New investors include East Penn Manufacturing, the world’s largest single-site, lead-acid battery facility; Crown Battery Manufacturing, a leader in deep-cycle applications; Leoch International, the largest lead acid battery exporter in China, and Power-Sonic Inc., a global specialty battery distributor.

Gridtential’s Silicon Joule™ technology is a novel breakthrough that replaces the lead grid inside a traditional lead battery with a plated silicon wafer similar to a solar cell. This approach translates to performance levels that match or exceed lithium-ion battery performance in many high power, medium energy and deep cycling applications, with significant cost, safety and recycling advantages. Gridtential is licensing the technology and building out its drop-in specialty Silicon wafer supply, enabling manufacturing partners to easily adapt their existing highly productive factories to provide high performing 12V to 48V batteries to their customers, without gigascale capital investments. The added funds will support further cost reductions and scaling of manufacturing processes to deliver 12 to 48V batteries, which can be one-third lighter than existing advanced lead batteries with performance up to 5x in power density.

With combined 2016 revenues exceeding $4 billion, this innovative group of battery industry manufacturers has been working jointly with Gridtential for four years to validate the potential of Silicon-Joule batteries. In that time, Gridtential has eclipsed its performance targets, providing demonstrations of the Silicon Joule technology with 6 partners in over 250 batteries. The results of those pilots showed an overall 2-5x cycle life improvement and demonstrated a scalable assembly method.

“East Penn continues to explore advanced battery technologies, and the company strongly believes that lead-based solutions will play a significant role in powering future needs,” said Kevin Smith, East Penn’s VP of Technology. “The remarkable strides that Gridtential has made in demonstrating advancements from a traditional lead-battery design, helps prove that East Penn’s lead battery beliefs are well founded. The company is excited to explore Silicon Joule technology, along with our other technology partners, in order to further support our customers and the industry’s growth in vehicle electrification and grid storage optimization.”

“Lead-acid batteries are the most cost-effective, safest form of energy storage — and they’re more recyclable than an aluminum can,” said Hal Hawk, President and CEO of Crown Battery Manufacturing. “Now, they’re even better. Because Gridtential’s new technology combines the safety, recyclability, and ROI of lead-acid batteries with up to 5X greater power density, lighter weight, and more than double the lifespan.”

“We are very excited about the potential for the Gridtential technology, and the advantages it can provide our customers. It will take lead acid battery performance and life up to the next level,” said Shawn Peng, Leoch International’s VP of Technology.

Gridtential is focused on applications ranging from 48V automotive hybrid and grid storage to back-up power for cloud computing, material handling equipment and many others. The 48V battery market for hybrid vehicles alone represents a $30 billion opportunity worldwide. While 12V electrical systems are straining to supply the power demanded by amenities and mechanical operations in contemporary car and truck models, 48V systems provide more than enough energy to support a variety of hybrid automotive features, such as stop-start energy regeneration and engine shut-off at higher speeds. Gridtential’s proprietary Silicon Joule battery technology will not only significantly reduce the cost barrier to create these systems, it will ensure that these high-performance hybrid vehicles achieve the best fuel economy possible.

“An investment like this from such a highly respected group of global battery producers is significant in two respects. First, it underscores our investors’ confidence that our licensable silicon-based bi-polar technology can change the game for advanced lead battery makers, giving them a competitive edge in the highest growth markets,” said Ray Kubis, Gridtential Chairman. “Second, it is an efficient contrast to the large capital sums going into lithium. Rather than spending our time and efforts on continuous fund raising, we’ve chosen a capital-light path with an existing global network of suppliers that will swiftly exceed gigascale production of advanced lead-based batteries to meet rapidly growing application demand.”

“This new influx of funding will allow Gridtential to expand support for its manufacturing partners and bolster R&D as we continue to identify new, industry-changing applications for our Silicon Joule technology,” said Christiaan Beekhuis, Gridtential CEO. “With help from our new strategic partners, we’ll now focus on refining our advanced, high-power designs, scaling up the silicon supply chain without driving up costs, and automating the assembly process to rival speeds familiar to high-volume producers of advanced lead-based batteries.”

Independent tests verify it — Gridtential boosts lead acid performance at 1/3 the cost of lithium-ion

SAN JOSE, July 13, 2015 /PRNewswire/ — Gridtential Energy, Inc., a provider of low-cost, high-performance energy storage technology, today announced that it has been selected by the Department of Energy (DOE) as one of a handful of companies to pursue validation analysis at Sandia’s Energy Storage Analysis Laboratory. The grant is designed to further the DOE’s strategic mission in the area of grid storage and coincides with Gridtential’s completion of 140 alpha units based on its Silicon Joule™ technology.

Flying in the face of Tesla’s recent declaration that lead acid is “dead”, recent independent tests have confirmed that Gridtential’s silicon-based approach to advance traditional lead acid significantly improves performance, while utilizing 40% less lead. The results point to Gridtential as an ideal solution for solar’s urgent need for 2 to 4 hour grid storage applications. At Sandia, the test plan is designed to address two use case scenarios:

  • Peak Shaving cycling. In compliance with Sandia’s standard test protocols, Gridtential’s batteries will run through a standard peak shaving application. Gridtential expects each to reach nearly 100% SOC after each charge cycle and 80-100% depth of discharge.
  • Partial State of Charge (PSoC) cycling. To gain a view of Gridtential’s long-term performance in a PSoC environment, Sandia will charge the battery to 100% SOC and then begin cycling it at a medium rate which is designed to bring sulfation issues to light very quickly.

Gridtential Energy has also been funded in part by an award from the California Energy Commission’s Energy Innovations Small Grant Program. The company has developed and tested internal prototypes of an advanced battery design that has 75% lower LCOE of traditional lead acid, 2x cycle life improvement at 80% depth of discharge and 2x greater available energy at same weight as current products. The seed funding will be used to develop full-scale demonstration units for field tests within the next year.

“Tesla is not the only company capable of producing a smart, sexy battery; the difference is ours is safe and scalable today. Via our battery manufacturing partners, we have access to hundreds of operating ‘gigafactories’ that can bring our Silicon Joule™ technology to market without retooling or massive investment,” said Christiaan Beekhuis, President and CEO of Gridtential Energy.
