Alpine 4 Holdings Inc announced that subsidiary ElecJet has revealed its AX and G-AX Class of solid-state batteries.
Also, it said ElecJet has completed an initial demonstration product run of its AX Class 31Ah Solid-State Batteries. The company will be distributing these batteries as test samples to various corporations upon request.
"What our team of engineers has achieved is a testament to the talented individuals we work with,” said ElecJet President Samuel Gong in a statement. “Unlike the competitors in the solid-state space, we are not just building prototypes, we are actually in production, and can deliver our batteries to companies seeking this solution today. We look forward to sharing the location of our US-based production facility in the coming months."
Alpine 4 said the AX Battery Class is a Ceramic Oxide solid-state battery and comes in the form of a 31Ah Solid-State Battery and a 10Ah Solid-State Battery. The AX battery was designed for ultra-energy dense applications that need a powerful battery solution but not necessarily the ultra-fast (8C-plus) charging that the G-AX Class Batteries can provide. Both the G-AX and AX use graphene in the battery cells but for different purposes and at different levels of the battery's design.
The AX Battery Class is still quite fast and has operating specifications of up to 4C charging. At a 4C rate of charge, the AX Class can charge in 15-minutes. Typical fast charging Lithium-Ion batteries charge between 0.5C and 1C, which equates to 1 hour at 1C and 2 hours at 0.5C. The AX Class can also retain 80% of its capacity for over 1,000 charging cycles.
With up to an 280Wh/kg energy density, Alpine 4 said the AX Class is a solution for Power walls, smaller ESS solutions, golf carts, and EV vehicles. And the production of an improved 360Wh/kg model (already tested in prototypes) will begin later in 2022, improving energy density by almost three-fold over lithium-polymer.
With 1,000 charge cycles and the typical range of an electric vehicle being 300 miles, an EV powered by the AX Class of batteries would be able to drive over 300,000 miles before the battery pack would see any significant degradation to its life cycle. Technical specifications show 1,200 charge cycles, with 1,000-charge cycles expected in an EV application.
As for the G-AX Class, it consists of a graphene-enhanced 31Ah Solid-State Battery and graphene-enhanced 50Ah Solid-State Battery, designed for ultra-fast (8C-plus) charging solutions for the EV Market that need a powerful battery solution while retaining over 80% of its capacity after 1,000 charges. At an 8C rate of charge, the G-AX Class can charge in under 8 minutes.
The G-AX Battery Class can be customized up to 50C charging. Also having 360Wh/kg, the G-AX Class was designed to be incorporated into a battery stack solution perfect for EV vehicles in the transportation industry that need to charge quickly. In line with the AX Class, an EV powered by the G-AX Class of batteries would also be able to drive over 300,000 miles before the battery pack would see any significant degradation to its life cycle.
"On top of all the incredible features solid-state batteries bring, one of the most unique features is safety,” noted Apline 4 CEO Kent Wilson.
Typical lithium batteries will combust with the slightest puncture. Our batteries have been tested to not only not catch on fire, but to hold voltage and still operate after being punctured by a nail, cut in half with scissors and even shot at with a handgun several times. This marks an evolution in the safety of batteries for all electrical devices moving forward and dramatically reduces the hazards of operating with battery equipped devices such as cell phones, EVs, ESS systems and autonomous drones like Vayu's G1 and US-2."
