US-based battery maker Gridtential has finalised the design of its commercial 24V GC2 battery using its silicon joule technology.
The company said it has an order backlog of more than 400 batteries and is set to begin shipments from Pennsylvania in October.
The batteries will be deployed in field trials across a range of cycling applications with global partners, and discussions are underway with other partners for additional trials.
The bi-pole design is expected to exceed 2,000 80% deep discharge cycles according to Ben Craft, VP of engineering.
Gridtential’s patented treated silicon wafers are said to displace the lead grid and top lead found in conventional lead batteries. This change reduces weight, enables higher heat tolerance, and significantly extends life by eliminating typical failure modes.
The company’s AGM battery technology is said to have a 4X longer life, up to 5X dynamic charge acceptance and up to 35% less weight than conventional lead batteries.
It said there is the ability for high margin sales growth without gigafactory investments with the new battery due to low material costs and the flexibility to utilise existing lead battery manufacturing equipment. It could be assembled on existing production lines.
Gridtential makes batteries with applications across multiple segments due to its stack-and-seal architecture, inspired by solar technology. This includes automotive, mobility vehicles, industrial equipment, ESS and reserve power systems.
