ʻO ka ʻoihana pākaukau lead-acid ma koʻu ʻāina he mōʻaukala ʻoi aku ma mua o hoʻokahi haneli mau makahiki. Ma muli o nā hiʻohiʻona o nā mea haʻahaʻa, ʻenehana maʻalahi, ʻenehana makua, haʻahaʻa haʻahaʻa ponoʻī, a me nā koi mālama ʻole, e hoʻomau ʻia ka mākeke i nā makahiki he nui e hiki mai ana. Ma nā kahua noi he nui, ʻo ka holomua ʻenehana o nā pākaʻi lead-acid i hāʻawi pono i ka hoʻomaikaʻi ʻana i ka hoʻokūkū aupuni. He kiʻekiʻe ka mana hydrogen a me ke kūpaʻa corrosion ikaika. Hoʻohana ʻia ia no ka hana ʻana i nā pahu pahu pahu lead-acid, hiki ke hoʻomaikaʻi i ka maikaʻi o ka electrode maikaʻi ʻole i ka oxygen o loko o ka pā a hoʻonui i ka pono o ka electrode maikaʻi i nā pōʻai hoʻokuʻu hohonu.
Hoʻohana ʻana i ka Aluminum Aluminum Calcium i loko o ka waihona waihona
He 160 mau makahiki ka mo'olelo o na 'akika Lead-acid. ʻAʻole hiki ke hoʻohālikelike ʻia kona ikehu kikoʻī nui a me kona ikehu kikoʻī me Ni-Cd, Ni-MH, Li ion a me Li polymer batteries. Akā, ma muli o kona kumukūʻai haʻahaʻa, maikaʻi ka hana hoʻokuʻu kiʻekiʻe o kēia manawa, a ʻaʻohe hopena hoʻomanaʻo, hiki ke hana ʻia i hoʻokahi pākahi mana nui (4500Ah) a me nā hana maikaʻi ʻē aʻe. No laila, hoʻohana nui ʻia i ka automotive, telecommunications, uila uila, UPS, kaʻaahi, pūʻali koa a me nā kahua ʻē aʻe, a ke kū nei kāna kūʻai ʻana ma mua o nā huahana mana kemika.
Pehea ka hoʻohana nui ʻia ʻana o ka calcium alloy i ka ʻoihana pākaukau
1. I mea e ho'ēmi ai i ka hoʻoheheʻe ʻia ʻana o ka wai pākaukau a hoʻemi i ka hana mālama ʻana i ka pākaukau, ua hana ʻo Hanring lāua ʻo Thomas [50] i kahi alloy lead-calcium i ka makahiki 1935, i hoʻohana ʻia no ka hana ʻana i nā pahu hoʻolei no nā ʻaʻa paʻa i hoʻohana ʻia i nā kikowaena kamaʻilio.
2. ʻO ka mea mānoanoa i hoʻohana mau ʻia i nā pākaukau mālama ʻole he Pb-Ca alloy. Wahi a ka ʻike, ua māhele ʻia i ka calcium kiʻekiʻe, ka calcium medium a me ka alloy calcium haʻahaʻa.
3. ʻO ke kēpau-calcium alloy ka paʻakikī o ka ua, ʻo ia hoʻi, ua hana ʻia ʻo Pb3Ca i loko o ka pahu alakaʻi, a ʻo ka hui intermetallic e hoʻoheheʻe i loko o ka matrix alakaʻi e hana i kahi pūnaewele paʻakikī.
ʻO Grid ka mea koʻikoʻi koʻikoʻi ʻaʻole i hana ʻia i loko o nā pākī lead-acid. Mai ka hoʻokumu ʻana o nā pākī lead-acid, ʻo Pb-Sb alloy ka mea nui loa no nā grids. Me ka puka ʻana mai o nā pākī lead-acid me ka mālama ʻole ʻia, ua lilo nā alloys Pb-Sb ʻAʻole hiki ke hoʻokō i nā koi o ka hoʻokō pono ʻole o nā pā, a ua hoʻololi mālie ʻia e nā alloys ʻē aʻe.
Ua ʻike nā haʻawina he hana maikaʻi loa ka Pb-Ca alloy, akā he koʻikoʻi kona ʻano corrosion intergranular, a ʻaʻole maʻalahi ka mālama ʻana i ka maʻi calcium, ʻoi aku ka nui o ka kiʻiʻoniʻoni passivation kiʻekiʻe i hoʻokumu ʻia ma luna o ka ʻili o ka pā pākaukau. ke kaʻina hana pākaukau a hoʻokuʻu. , E hoʻonui i ka pōʻino o ka hiki wawe (PCL) o ka pākaukau, no laila e hoʻopōkole loa i ke ola lawelawe o ka pākaukau, ʻo ia ka mea ʻoi loa ka mana o ka mākia maikaʻi. ʻO ka hoʻohui ʻana i kahi liʻiliʻi o ka alumini ka hopena o ka pale ʻana i ka calcium. Ua ʻike ʻia ka noiʻi e hiki i ka tin ke hoʻomaikaʻi i ka hana o ke kiʻiʻoniʻoni passivation a hoʻonui i ka hana pōʻai hohonu o ka pā.
