Mayankho osiyanasiyana omwe atchulidwa pamwambapa onse amagwiritsidwa ntchito popanga zenizeni ndi makampani opanga ma batire a lithiamu akunja ndi akunja. Chifukwa cha nthawi yopangira zosiyanasiyana komanso machitidwe osiyanasiyana aukadaulo, njira zothanirana ndi njira zosiyanasiyana zimagwiritsidwa ntchito kwambiri pamakampani, koma makampani ali ndi zofunikira zapamwamba pakuchita bwino komanso khalidwe. Zikuyenda bwino nthawi zonse, ndipo matekinoloje atsopano adzagwiritsidwa ntchito posachedwa ndi makampani omwe ali patsogolo paukadaulo.
Bizinesi yatsopano yamagetsi yaku China idayamba mochedwa kwambiri ndipo yakula kwambiri motsogozedwa ndi mfundo zadziko. Ukadaulo wofananirawo wapitilira kupita patsogolo ndi kuyesetsa kwamakampani onse, ndipo afupikitsa kusiyana ndi makampani otsogola apadziko lonse lapansi. Monga wopanga zida za batri ya lithiamu, Maven akuwunikanso madera ake omwe amapindula nawo, kuthandiza kukonzanso zida zonyamula batire, ndikupereka mayankho abwinoko pakupangira makina atsopano amagetsi osungira batire.
