Skeleton Technologies has launched its fast charging ‘superbattery’ that builds on its supercapacitor technology.
The 2.25V battery can charge in 60 seconds to allow for up to 30 minutes of driving with a ppeak charging rate of 100C. The continuous charging rate is 20C, with a lifetime of 50 000 charge/discharge cycles, ten times that of Lithium-Ion batteries, providing much longer lifetime. The battery cell has a power density of 10kW/kg and energy density of 65Wh/kg.
Skeleton in Germany is a leading developer and manufacturer of supercapacitors through deals with Siemens and other suppliers.
The design does not use cobalt, nickel, graphite, or copper, using its curved graphene instead. It also uses less then 5% lithium, and so does not suffer from thermal runaways, so there is no need for thermal propagation measures.

The energy density and the extended temperature range of -30 to +50 C means the battery is being tested in hybrid and fuel cell EVs, buses, trucks, and charging infrastructure.
Skeleton is working with Shell and seven other partners to use the technology in electric mining vehicles. These include Microvast, Stäubli, Carnegie Robotics, Heliox, Spirae, Alliance Automation and Worley to provide a fast charging infrastructure.
The Shell Mining Electrification Solutions for Off-Road Vehicles consists of power provisioning and microgrids to provide a consistent and reliable supply of renewable power, with the fast charging batteries and in-vehicle energy storage.
