Avadain’s large, thin and nearly defect free graphene flakes significantly increased supercapacitor performance in an independent test conducted in Germany.
Adding 0.50% of Avadain’s graphene flakes to the supercapacitor’s electrodes enabled faster charging/discharging, 100% depth of discharge and increased power density. It also enabled constant specific capacitance as the discharge current increased, whereas reduced graphene oxide (rGO) flakes and carbon black had declining specific capacitance. This is great news for the transportation (EVs, HVs, electric buses and electric trains), industrial, consumer electronics and energy industries, which are increasingly relying on supercapacitors to improve performance.
Future global energy use will depend on consumers and industry generating, storing and using energy more efficiently, and supercapacitors will be one of the leading technologies for intermittent storage, energy harvesting and high-power delivery.
The global market for supercapacitors is “expected to hit US $25 billion by 2030, growing at a CAGR of 23.5% from year 2022 to 2030,” according to Precedence Research. Emerging technologies research firm IDTechEx projects that the market for conductive material for supercapacitors will reach $8 billion in 2025. Supercapacitors are one of many opportunities for Avadain’s graphene flakes in clean transportation.
