Bipolar nickel-hydrogen battery for 2021 Toyota Aqua

Toyota’s new Acqua compact HEV comes with a bipolar nickel-hydrogen battery, a world first for a road vehicle according to the Japanese automotive giant (writes Peter Donaldson). Conventional non-bipolar nickel-hydrogen batteries have a much lower energy density than lithium-ion versions but much longer service lives. Compared with the nickel-hydrogen battery in the previous-generation Aqua, says […]
