Short answer is that MNS altered the battery chemistry process and made C4V's IP commercially viable. MNS/C4V are contracted to equal use of the new technology which remains IP protected. Great synergy.
Frank Houlis is an absolute genius that helped make C4V's processes commercially viable. The MNS/C4V synergy has been the catalyst for all future battery factory plans. Battery chemistry that is better for the environment and allows batteries to be made outside of China at a competitive or cheaper rate.
