My guess is Leclanche

Last time I checked we are still in pilot project with them, upscaling TiO2 production in order to meet requirements for stage 2, hoping to get some update in that regard.

Leclanche signed an agreement with Skoda electric, which is an ebus manufacturer. So a successful outcome of this pilot project will mean Leclanche potentially becoming a big customer supplying batteries for electric buses!
