Until now, existing iron-based cathodes lacked sufficient storage capacity to power a long-range EV.
In the second study, published in Energy & Environmental Science, the researchers explain how they discovered the potential of another sustainable alternative: manganese-based disordered rock-salts (Mn-DRX).
The new material offers high energy content at a low cost, but its practical application has been hindered by low electrical conductivity and structural instability. However, in collaboration with a team from the Korea Advanced Institute of Science and Technology, the Canadian group found a novel solution. Using multi-walled carbon nanotubes and an adhesive binder as electrode additives, they achieved the highest practical-level energy density ever recorded for Mn-DRX cathodes.
“Our findings hold immense promise for the future of lithium-ion battery development, offering a pathway towards more affordable and sustainable…
