Batire yachitsulo-mpweya ndi zinthu zogwira ntchito zomwe zimagwiritsa ntchito zitsulo zokhala ndi mphamvu zopanda ma electrode, monga magnesium, aluminiyamu, zinki, mercury ndi chitsulo, monga electrode negative, ndi okosijeni kapena mpweya wabwino mumlengalenga monga electrode yabwino.Batire ya Zinc-air ndiye batire yomwe yafufuzidwa kwambiri komanso yogwiritsidwa ntchito kwambiri pagulu la batri lazitsulo.M'zaka 20 zapitazi, asayansi achita kafukufuku wambiri pa batri yachiwiri ya zinc-air.Sanyo Corporation yaku Japan yapanga batire yayikulu yachiwiri ya zinc-air.Batire ya zinki-mpweya ya thirakitala yokhala ndi voliyumu ya 125V ndi mphamvu ya 560A · h yapangidwa pogwiritsa ntchito njira ya mpweya ndi electro-hydraulic force circulation.Zimanenedwa kuti zakhala zikugwiritsidwa ntchito m'magalimoto, ndipo kachulukidwe kake kameneka kamatha kufika 80mA / cm2, ndipo kuchuluka kwake kumatha kufika 130mA / cm2.Makampani ena ku France ndi Japan amagwiritsa ntchito njira yozungulira zinki slurry kuti apange zinki-mpweya yachiwiri, ndikubwezeretsa zinthu zogwira ntchito kunja kwa batire, ndi mphamvu yeniyeni ya 115W · h/kg.

Ubwino waukulu wa batri yachitsulo-mpweya:

1) Mphamvu yapamwamba kwambiri.Popeza zinthu zomwe zimagwiritsidwa ntchito mu electrode ya mpweya ndi mpweya mumlengalenga, sizitha.Mwachidziwitso, mphamvu ya electrode yabwino ndi yopanda malire.Komanso, zinthu yogwira ndi kunja batire, kotero ongolankhula enieni mphamvu ya batire mpweya ndi lalikulu kwambiri kuposa onse zitsulo okusayidi elekitirodi.The theoretical mphamvu yeniyeni ya batire yamagetsi yachitsulo nthawi zambiri imakhala yoposa 1000W · h/kg, yomwe ndi yamagetsi opangira mphamvu zamagetsi.
(2) Mtengo wake ndi wotsika mtengo.Batire ya zinki-mpweya sagwiritsa ntchito zitsulo zamtengo wapatali ngati ma electrode, ndipo zida za batri ndizinthu wamba, kotero mtengo wake ndi wotsika mtengo.
(3) Kuchita bwino.Makamaka, batire ya zinki-mpweya imatha kugwira ntchito pakachulukidwe kakang'ono kamakono pambuyo pogwiritsa ntchito porous zinc electrode ndi alkaline electrolyte.Ngati okosijeni wangwiro agwiritsidwa ntchito m'malo mwa mpweya, ntchito yotulutsa imathanso kusintha kwambiri.Malinga ndi kuwerengera kwamalingaliro, kachulukidwe kakali pano atha kuonjezedwa pafupifupi nthawi 20.

Batire yachitsulo-mpweya ili ndi zovuta izi:

1）, batire silingathe kusindikizidwa, zomwe zimakhala zosavuta kuchititsa kuyanika ndi kukwera kwa electrolyte, zomwe zimakhudza mphamvu ndi moyo wa batri.Ngati electrolyte ya alkaline ikugwiritsidwa ntchito, ndizosavuta kuyambitsa carbonation, kuonjezera kukana kwa mkati mwa batri, komanso kukhudza kutulutsa.
2）, ntchito yosungirako yonyowa ndiyosauka, chifukwa kufalikira kwa mpweya mu batire kupita ku electrode yoyipa kumafulumizitsa kudzitulutsa kwa electrode yoyipa.
3）, kugwiritsa ntchito porous zinki monga electrode negative kumafuna mercury homogenization.Mercury sikuti imangowononga thanzi la ogwira ntchito komanso imawononga chilengedwe, ndipo iyenera kusinthidwa ndi non-mercury corrosion inhibitor.

Batire yachitsulo-mpweya ndi zinthu zogwira ntchito zomwe zimagwiritsa ntchito zitsulo zokhala ndi mphamvu zopanda ma electrode, monga magnesium, aluminiyamu, zinki, mercury ndi chitsulo, monga electrode negative, ndi okosijeni kapena mpweya wabwino mumlengalenga monga electrode yabwino.Alkaline electrolyte amadzimadzi njira zambiri ntchito monga electrolyte njira ya zitsulo mpweya batire.Ngati lifiyamu, sodium, kashiamu, etc. ndi mphamvu zoipa elekitirodi ntchito ngati elekitirodi zoipa, chifukwa amatha kuchita ndi madzi, okha sanali amadzimadzi organic electrolyte monga phenol zosagwira olimba electrolyte kapena inorganic electrolyte monga LiBF4 mchere njira angathe. kugwiritsidwa ntchito.

Magnesium-air batri

Chitsulo chilichonse chokhala ndi ma elekitirodi olakwika komanso ma elekitirodi a mpweya amatha kupanga batire yofananira ndi mpweya.Kuthekera kwa ma elekitirodi a magnesium ndi koyipa ndipo ma electrochemical ofanana ndi ochepa.Itha kugwiritsidwa ntchito kuphatikiza ndi elekitirodi ya mpweya kuti ipange batire ya mpweya wa magnesium.Mphamvu yamagetsi yofanana ndi magnesium ndi 0.454g/(A · h) Ф=- 2.69V. Mphamvu yeniyeni ya batire ya magnesium-air ndi 3910W · h/kg, yomwe ndi nthawi 3 ya batri ya zinc-air ndi 5 ~ Nthawi 7 za batri ya lithiamu.Mzati yoyipa ya batire ya mpweya wa magnesium ndi magnesium, mtengo wabwino ndi okosijeni mumlengalenga, ma electrolyte ndi yankho la KOH, komanso njira yosalowerera ndale ya electrolyte ingagwiritsidwenso ntchito.
Mphamvu ya batri yayikulu, kuthekera kotsika mtengo komanso chitetezo champhamvu ndi zabwino zazikulu zamabatire a magnesium ion.Maonekedwe a divalent a magnesium ion amapangitsa kuti zitheke kunyamula ndi kusunga ndalama zambiri zamagetsi, ndi mphamvu yamphamvu ya 1.5-2 nthawi ya batri ya lithiamu.Nthawi yomweyo, magnesium ndiyosavuta kutulutsa ndikugawidwa kwambiri.China ili ndi mwayi wokwanira wazinthu zothandizira.Pambuyo popanga batire ya magnesium, mwayi wake wokwera mtengo komanso chitetezo chazinthu ndizokwera kuposa batri ya lithiamu.Pankhani ya chitetezo, magnesium dendrite sidzawoneka pamtengo woyipa wa batri ya magnesium ion panthawi yothamangitsa ndi kutulutsa, zomwe zingapewe kukula kwa lithiamu dendrite mu batri ya lithiamu kuboola diaphragm ndikupangitsa kuti batire ikhale yaifupi, moto ndi kuphulika.Ubwino womwe uli pamwambapa umapangitsa kuti batire ya magnesium ikhale ndi chiyembekezo chakukula komanso kuthekera.

Pankhani ya chitukuko chaposachedwa cha mabatire a magnesium, Qingdao Institute of Energy ya Chinese Academy of Sciences yapita patsogolo bwino pamabatire achiwiri a magnesium.Pakalipano, yadutsa m'botolo laumisiri popanga mabatire achiwiri a magnesium, ndipo yapanga selo limodzi lokhala ndi mphamvu zambiri za 560Wh / kg.Galimoto yamagetsi yokhala ndi batire yathunthu ya magnesium yomwe idapangidwa ku South Korea imatha kuyendetsa bwino makilomita 800, yomwe ili kuwirikiza kanayi kuchuluka kwa magalimoto omwe ali ndi batire a lithiamu.Mabungwe angapo aku Japan, kuphatikiza Battery ya Kogawa, Nikon, Nissan Automobile, Tohoku University of Japan, Rixiang City, Miyagi Prefecture, ndi mabungwe ena ofufuza zamakampani ndi mayunivesite ndi madipatimenti aboma akulimbikitsa mwachangu kafukufuku wamkulu wa batire ya mpweya wa magnesium.Zhang Ye, gulu kafukufuku Modern Engineering College of Nanjing University, ndi ena anapanga awiri wosanjikiza gel electrolyte, amene anazindikira chitetezo cha magnesium zitsulo anode ndi malamulo kumaliseche, ndipo analandira magnesium mpweya batire ndi mkulu mphamvu kachulukidwe. 2282 W h · kg-1, kutengera mtundu wa maelekitirodi onse a mpweya ndi ma elekitirodi a magnesium), omwe ndi apamwamba kwambiri kuposa batire ya mpweya wa magnesium ndi njira za alloying anode ndi anti-corrosion electrolyte m'mabuku apano.
Nthawi zambiri, batire la magnesium likadali pachiwonetsero choyambirira pakali pano, ndipo padakali njira yayitali kuti ipititse patsogolo kukwezedwa ndi kugwiritsa ntchito kwakukulu.
