Ukadaulo, Ubwino, ndi Mtengo wa Mabatire a Lithium-ion

Kodi batire ya lithiamu-ion imagwira ntchito bwanji? Kodi ili ndi maubwino otani kuposa batire ya asidi wotsogolera? Kodi kusungirako batire la lithiamu-ion kumalipira liti?A batri ya lithiamu-ion(yachidule: batri ya lithiumion kapena batri ya Li-ion) ndilo liwu lodziwika bwino la accumulators pogwiritsa ntchito mankhwala a lithiamu m'magawo onse atatu, mu electrode yolakwika, mu electrode yabwino komanso mu electrolyte, selo la electrochemical cell. Batire ya Lithium-ion ili ndi mphamvu zenizeni zenizeni poyerekeza ndi mitundu ina ya mabatire, koma imafunika mabwalo achitetezo amagetsi pamapulogalamu ambiri, chifukwa amakhudzidwa ndi kutulutsa kwakukulu komanso kuchulukira.Mabatire a dzuwa a lithiamu ion amaperekedwa ndi magetsi kuchokera ku photovoltaic system ndikutulutsidwanso ngati pakufunika. Kwa nthawi yayitali, mabatire otsogolera ankatengedwa ngati njira yabwino yothetsera mphamvu ya dzuwa pazifukwa izi. Komabe, kutengera mabatire a lithiamu-ion ali ndi zabwino zambiri, ngakhale kugula kumalumikizidwabe ndi ndalama zowonjezera, zomwe, komabe, zimabwezeredwa pogwiritsa ntchito cholinga.Mapangidwe Aukadaulo ndi Makhalidwe Osungira Mphamvu Zamabatire a Lithium-ionMabatire a lithiamu-ion samasiyana kwenikweni ndi mabatire a lead-acid pamapangidwe awo onse. Chonyamulira chokhacho chimakhala chosiyana: Batire ikaperekedwa, ma ion a lithiamu "amasuntha" kuchokera ku electrode yabwino kupita ku electrode yoyipa ya batri ndikukhalabe "kusungidwa" pamenepo mpaka batire itatulutsidwanso. Ma conductor apamwamba kwambiri a graphite nthawi zambiri amagwiritsidwa ntchito ngati ma elekitirodi. Komabe, palinso mitundu yosiyanasiyana yokhala ndi ma conductor achitsulo kapena ma cobalt conductors.Kutengera ma conductor omwe amagwiritsidwa ntchito, mabatire a lithiamu-ion adzakhala ndi ma voltages osiyanasiyana. Electrolyte yokha iyenera kukhala yopanda madzi mu batri ya lithiamu-ion popeza lithiamu ndi madzi zimayambitsa chiwawa. Mosiyana ndi omwe amatsogolera-asidi, mabatire amakono a lithiamu-ion (pafupifupi) alibe zotsatira za kukumbukira kapena kudzipangira okha, ndipo mabatire a lithiamu-ion amasunga mphamvu zawo zonse kwa nthawi yaitali.Mabatire osungira mphamvu ya lithiamu-ion nthawi zambiri amakhala ndi manganese, faifi tambala ndi cobalt. Cobalt (mawu akuti mankhwala: cobalt) ndi chinthu chosowa kwambiri ndipo chifukwa chake chimapangitsa kupanga mabatire osungira a Li kukhala okwera mtengo. Kuphatikiza apo, cobalt imawononga chilengedwe. Chifukwa chake, pali zoyeserera zingapo zopangira zida za cathode zamabatire a lithiamu-ion high-voltage opanda cobalt.Ubwino wa Mabatire a Lithium-ion Pamabatire a Lead-acid◎Kugwiritsa ntchito mabatire amakono a lithiamu-ion kumabweretsa zabwino zingapo zomwe mabatire osavuta a lead-acid sangathe kupereka.◎Chifukwa chimodzi, amakhala ndi moyo wautali wautumiki kuposa mabatire a lead-acid. Batire ya lithiamu-ion imatha kusunga mphamvu ya dzuwa kwa zaka pafupifupi 20.◎Kuchuluka kwa kuchuluka kwa kuyitanitsa ndi kuya kwa kutulutsa kumakhalanso kokulirapo kuposa ndi mabatire otsogolera.◎Chifukwa cha zinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito popanga, mabatire a lithiamu-ion ndi opepuka kwambiri kuposa mabatire otsogolera komanso ophatikizana. Choncho, amatenga malo ochepa panthawi ya kukhazikitsa.◎Mabatire a lithiamu-ion alinso ndi zinthu zosungirako bwino podzitulutsa okha.◎Kuphatikiza apo, munthu sayenera kuiwala za chilengedwe: Chifukwa mabatire otsogolera sakhala ochezeka makamaka pakupanga kwawo chifukwa cha kutsogolera komwe kumagwiritsidwa ntchito.Zithunzi Zaukadaulo Zamabatire a Lithium-ionKumbali ina, ziyenera kutchulidwanso kuti, chifukwa cha nthawi yayitali yogwiritsira ntchito mabatire otsogolera, pali maphunziro opindulitsa kwambiri a nthawi yayitali kuposa mabatire atsopano a lithiamu-ion, kotero kuti ntchito yawo ndi ndalama zogwirizana nazo. imathanso kuwerengedwa bwino komanso modalirika. Kuonjezera apo, chitetezo cha mabatire amakono otsogolera ndi abwino kwambiri kuposa mabatire a lithiamu-ion.M'malo mwake, kudera nkhawa za zolakwika zowopsa m'maselo a li ion sikulinso kopanda maziko: Mwachitsanzo, ma dendrites, mwachitsanzo, ma depositi a lithiamu, amatha kupanga pa anode. Kuthekera koti izi zimayambitsa mabwalo afupikitsa, motero pamapeto pake kumapangitsanso kutha kwa kutentha (kuthamanga kwamphamvu ndi kutentha kwamphamvu, kudzipangitsa kudzikweza), kumaperekedwa makamaka m'maselo a lithiamu omwe ali ndi zigawo zotsika kwambiri zama cell. Muzovuta kwambiri, kufalikira kwa cholakwikachi ku maselo oyandikana nawo kungayambitse kutengeka kwa unyolo ndi moto mu batri.Komabe, monga makasitomala ochulukirachulukira amagwiritsa ntchito mabatire a lithiamu-ion monga mabatire a dzuwa, zotsatira zophunzirira za opanga ndi kuchuluka kwakukulu kopanga zimabweretsanso kupititsa patsogolo luso la kusungirako ntchito komanso chitetezo champhamvu cha batri la lithiamu-ion komanso kutsika mtengo kwina. . Chitukuko chamakono cha mabatire a Li-ion chikhoza kufotokozedwa mwachidule m'magulu otsatirawa:

Kutha Kosungirako Ndi Mtengo Wa Mabatire a Solar Lithium-ionMtengo wa batire ya solar ya lithiamu-ion nthawi zambiri imakhala yokwera kuposa ya batire ya acid-acid. Mwachitsanzo, mabatire otsogolera okhala ndi mphamvu ya5kw papanopa mtengo avareji ya madola 800 pa kilowatt ola mphamvu mwadzina.Zofananira za lithiamu, kumbali ina, zimawononga madola 1,700 pa ola la kilowatt. Komabe, kufalikira pakati pa machitidwe otsika mtengo ndi okwera mtengo kwambiri ndi apamwamba kwambiri kuposa machitidwe otsogolera. Mwachitsanzo, mabatire a lithiamu okhala ndi 5 kWh amapezekanso pamtengo wochepera $ 1,200 pa kWh.Ngakhale ndalama zambiri zogulira zimakhala zokwera mtengo, mtengo wa batire ya lithiamu-ion dzuwa pa ola la kilowatt yosungidwa ndi yabwino kuwerengeredwa pa moyo wonse wautumiki, popeza mabatire a lithiamu-ion amapereka mphamvu kwa nthawi yayitali kuposa mabatire a asidi-asidi, kusinthidwa pakapita nthawi.Choncho, pogula batire yosungiramo batire, munthu sayenera kuchita mantha ndi ndalama zogulira zokwera mtengo, koma nthawi zonse ayenera kugwirizanitsa mphamvu zachuma za batri ya lithiamu-ion ku moyo wonse wautumiki ndi chiwerengero cha maola osungidwa a kilowatt.Njira zotsatirazi zitha kugwiritsidwa ntchito kuwerengera manambala onse ofunikira a lithiamu-ion batire yosungira makina a PV:1) Kuchulukira mwadzina * Malipiro ozungulira = Theoretical yosungirako mphamvu.2) Theoretical yosungirako mphamvu * Kuchita bwino * Kuzama kwa kutulutsa = Kuthekera kosungirako3) Mtengo wogula / Mphamvu yosungirako yogwiritsidwa ntchito = Mtengo pa kWh yosungidwa

BSLBATT: Wopanga mabatire a Lithium-ion SolarPakali pano pali opanga ambiri ndi ogulitsa mabatire a lithiamu-ion.BSLBATT lithiamu-ion mabatire a solargwiritsani ntchito maselo a A-grade LiFePo4 ochokera ku BYD, Nintec, ndi CATL, kuwaphatikiza, ndikuwapatsa makina owongolera (makina owongolera batri) omwe amasinthidwa kuti azitha kusungirako mphamvu ya photovoltaic kuti atsimikizire kugwira ntchito moyenera komanso kopanda mavuto kwa selo iliyonse yosungiramo ngati komanso ndondomeko yonse.
