Graphene-based supercapacitor offers energy density comparable to NiMH battery, but with rapid charge and discharge

Green Car Congress

These values are comparable to those of NiMH batteries, the researchers note, but the new supercapacitor offers the ability to be charged or discharged within seconds or minutes. Researchers from Nanotek Instruments and Angstron Materials have developed a graphene-based supercapacitor that exhibits a specific energy density of 85.6

Life cycle analysis of three battery chemistries for PHEVs and BEVs; environmental impacts higher than expected

Green Car Congress

They compiled a transparent life cycle inventory (LCI) in a component-wise manner for nickel metal hydride (NiMH), nickel cobalt manganese lithium-ion (NCM), and iron phosphate lithium-ion (LFP) batteries. A paper on the study appears in the ACS journal Environmental Science & Technology. —Majeau-Bettez et al.

Get out of the way diesel! Toyota Prado petrol-electric hybrid SUV coming to Australia as soon as 2024

EV Central

The system includes a 35kW electric motor integrated within its eight-speed automatic transmission and a 1.87kWh NiMH battery pack to charge it. That Prado 250’s hybrid system has already been seen with the HiLux-sized US-spec Toyota Tacoma ute and is expected to eventually come here in the Prado 250’s sibling, the Lexus GX.
