From Inside EV article, talking about Manganese demand going forward:

Moving forward, we see significant growth in the manganese market due to its applications in clean energy. More specifically, we anticipate the growing use of nickel-metal hydride (NiMH) electric vehicle batteries and lithium-ion (Li-ion) batteries to be major catalysts for manganese demand. NiMH batteries are predominantly used in hybrid vehicles, including the Toyota Prius. The Li-ion battery, of course, takes center-stage due to Tesla’s notoriety and lofty production targets.
The newest up-and-coming technology to use manganese is the so-called lithiated manganese dioxide (LMD) battery. A typical LMD battery uses 61% of manganese in its mix and only 4% lithium. LMDs have numerous benefits, including providing higher power output, thermal stability, and improved safety compared to regular lithium-ion batteries.
LMDs are already in production, and are currently used in electric cars like the Chevy Volt and Nissan Leaf. These cheaper electric cars, as opposed to the narrower luxury-segment that Tesla operates in, should be a significant part of the budding clean energy revolution.
Finally, there is a game-changing application of manganese worth mentioning: off-the-grid power. Tesla and its Powerwall batteries are breaking ground here, and the market is only poised to grow.
