  Gridtential Energy develops Silicon Joule, an advanced AGM bipolar battery technology for power applications including personal electric vehicles, renewable energy storage systems and hybrid automotive. The company offers Silicon Joule reference batteries, development kits, bipolar materials and non-exclusive licenses that enable manufacturing partners to adapt factories to produce high-voltage 24V, 36V and 48V batteries without gigascale capital investments. Target markets include hybrid-automotive, Low-Speed EV (LSEV), energy storage systems (ESS) and telecom backup. Silicon Joule is already in use by 12 battery partners and several OEMs. Gridtential, led by CEO John Barton, raised $12M in this financing and has raised $28M to date; it will use the proceeds to support a new production line of advanced lead reference batteries, including a single-block 24V deep-cycle lead battery. The company is based in Santa Clara, Calif. Gridtential, based in Santa Clara, CA and led by CEO Christiaan Beekhuis, has developed Silicon Joule® Technology, a battery architecture that pairs lead-acid attributes (low cost, safety, recyclability, wide temperature range) with lithium‑ion advantages (fast charge/discharge, high depth of discharge, long cycle life). The company targets applications including backup power, grid storage (including microgrids), portable power equipment, mobility (wheelchairs, golf carts, forklifts) and hybrid cars. Gridtential intends to expand development and licensing agreements to meet global demand across automotive, backup power, grid solutions and mobility industries. The company completed an $11M Series B equity funding to support those plans. Existing industry investors remain involved alongside new strategic battery manufacturers. No operating metrics such as revenue or user counts were disclosed in the article. Gridtential Energy develops a Silicon Joule battery architecture that replaces the lead grid with a plated silicon wafer, aiming to match or exceed lithium‑ion performance in many high‑power, medium‑energy, and deep‑cycling applications. The technology preserves traditional lead battery benefits—low cost, safety, recyclability, wide temperature range, and long cycle life—while enabling faster charge/discharge and deeper depth of discharge. Gridtential licenses the Silicon Joule technology and is building a specialty silicon wafer supply so manufacturing partners can adapt existing factories to produce 12V–48V batteries without gigascale capital investment. The company is led by CEO Christiaan Beekhuis and is based in Santa Clara, California. It completed a $6M funding round and said it will use the proceeds to scale operations and development efforts. Beta production with licensing partners was slated for later in the year, with rapid scale up to commercial production targeted for late 2017. Gridtential Energy develops a low-cost, scalable battery architecture that improves energy density, cycling performance and battery life. Founded in 2010 and based near downtown San Jose at the San Jose BioCube Innovation Center, the company has developed and tested internal prototypes of an advanced battery design. Gridtential has received funding from the California Energy Commission's Energy Innovations Small Grant Program and has relationships with key suppliers to accelerate development of high-volume production capabilities. The company is initially targeting existing battery applications that represent over $8B in annual sales and plans to position products for the emerging smart-grid energy storage market as the technology matures. The $1M seed funding led by The Roda Group will be used to develop full-scale demonstration units for field tests within the next year. Daniel Miller and Marty Reed of The Roda Group will join Gridtential's board; Christiaan Beekhuis serves as president and CEO.
