Zinc systems developer Eos Energy Systems has started commercial production at its Pennsylvania-based manufacturing facility following the company’s successful completion of Site Acceptance Testing for its Battery Line 2.
With its Battery Line 1 already deployed, the Line 2 production shows the company has demonstrated an ability to replicate, improve, and implement automated battery production at a second facility as well.
Invinity Sells 32 MWh system to Pacific Steel Group
Vanadium flow developer Invinity Energy Systems has sold a 32 MWh system to leading U.S. reinforcing steel fabricator Pacific Steel Group.
Collocated with a solar array rated at over 40 MWp, Invinity’s battery will be the largest vanadium flow battery system in North America to date. The array will power the facility’s operations recycling 500,000 tons of scrap metal annually.
IoT devices are getting thinner and smaller – but legacy coin cells can only get so tiny. As coin cells shrink, the small batteries’ internal resistance increases.
Zinc-manganese dioxide player Zinergy has a solution to the technological deadlock. The firm’s printed batteries use a planar architecture to move active materials from a rigid metal casing to a much larger, thinner surface area – improving current distribution and reducing internal resistance.
