Ka Moolelo o NiMH Bateri

Ka Invention

Ma hope i ka makahiki 1967, ua loaʻa i kekahi mau ʻālohilohi ma Battelle-Geneva Research Center ka lolo a hoʻokumu i ka pila NiMH. Hoʻokumu ʻia ia ma ka hui ʻana o nā alloys Ti2Ni+TiNi+x sintered a me nā electrodes NiOOH. Ua komo ʻo Daimler-Benz lāua ʻo Volkswagen AG a kākoʻo i ka hoʻomohala ʻana o ka pākaukau i nā makahiki ʻelua e hiki mai ana.

Ka Hoomaikai

I nā makahiki 70, ua kūʻai kūʻai ʻia ka pākaukau nickel-hydrogen no nā noi ukali, a ua hoʻāla kēia i ka hoihoi i ka ʻenehana hydride ma ke ʻano he ʻokoʻa no ka mālama ʻana i ka hydrogen nui. Ua hoʻomohala ʻo Philips Laboratories a me CNRS o Farani i nā ʻāpana huila ikaika hou i hoʻohui ʻia me nā metala honua ʻole no ka electrode maikaʻi ʻole. Akā ʻaʻole paʻa kēia mau ʻāpana i ka electrolyte alkaline, no laila ʻaʻole kūpono lākou no ka hoʻohana ʻana o ka mea kūʻai.

ʻO ka Breakthrough

Ma 1987, ua hana ʻo Willems lāua ʻo Buschow i kahi holomua me kā lākou hoʻolālā pākaukau, kahi i hoʻohana ʻia i ka hui ʻana o La0.8Nd0.2Ni2.5Co2.4Si0.1. Ua mālama kēia pākaukau i 84% o kona hiki ke hoʻouka ma hope o 4000 mau kaʻina hoʻoiho. ʻOi aku ka maikaʻi o ka hoʻohana ʻana i ka mischmetal ma kahi o ka lanthanum i hoʻomohala koke ʻia.

Ka Papa Consumer

I ka makahiki 1989, ua loa'a ka mea kū'ai mua loa i nā pūnaewele NiMH, a i ka makahiki 1998, ua ho'omaika'i 'o Ovonic Battery Co. Ma ka makahiki 2008, ua hana ʻia ma luna o ʻelua miliona mau kaʻa hybrid ma ka honua holoʻokoʻa me nā pihi NiMH.

Ka Kaulana

I ka Hui ʻEulopa, ua hoʻololi nā ʻokoʻa NiMH i nā ʻeke Ni-Cd no ka hoʻohana ʻana i nā mea kūʻai aku. Ma Iapana i ka makahiki 2010, ua kūʻai ʻia ʻo NiMH he 22% o nā ʻeke kelepona hiki ke hoʻihoʻi hou ʻia, a ma Switzerland i ka makahiki 2009, aia ma kahi o 60% ka helu helu like. Akā ua hāʻule kēia pākēneka i ka manawa ma muli o ka piʻi ʻana o ka hana ʻana o nā pā lithium-ion.

ʻO ka Future

I ka makahiki 2015, ua hana ʻo BASF i kahi microstructure i hoʻololi ʻia i ʻoi aku ka lōʻihi o nā pila NiMH, e ʻae ana i nā loli i ka hoʻolālā cell i mālama i ke kaumaha nui a hoʻonui i ka ikehu kikoʻī i 140 watt-hola no ka kilo. No laila ke nānā aku nei ka wā e hiki mai ana o nā pihi NiMH!
