Dr Steve Sloop, CEO of OnTo Technology, describes how direct recycling holds the key to the cost-effective re-purposing of cathodes by unlocking the potential of the original energy and materials used to first fabricate them. By repairing rather than breaking-up the metals used in cathode construction considerable energy and materials, that would otherwise be wasted, can be saved.
The lithium-ion battery industry was launched in 1991 with cells powering portable video recorders. The prototypical original cathode chemistry, lithium cobalt oxide (LCO), if recycled at all in the early years, was done so with an . . .
