Chabwino n'chiti, Mabatire a Lithium-Ion kapena Lithium Iron Phosphate?
Pazosungirako zokhazikika komanso zoyendera zamalonda, LFP imapambana pamitengo yonse ya umwini pafupifupi 80% ya mapulojekiti omwe tikuwona. NMC imamvekabe pakulemera-kuchepa kwa ntchito ndi kuzizira{3}}kutumiza kwanyengo popanda kuwongolera bajeti. Ndilo yankho lalifupi.
Yankho lalitali limakhudza momwe ntchito yanu ikuyendera, zovuta zapatsamba lanu, komanso moona mtima, zomwe CFO yanu ikufuna kusaina kuti iwononge ndalama zam'tsogolo ndi moyo wanu. Ngati mukufanizira mawu amalonda pompano kapena mukupangira RFP, zotsalazo zikuphatikiza zomwe taphunzirapo.
Kulanda kwa LFP msika kudachitika mwachangu kuposa momwe akadaulo ambiri adaneneratu. 49% ya kuchuluka kwa mabatire a EV padziko lonse lapansi mchaka cha 2024, pafupi-kuchuluka kwa ma gridi yosungirako. Tesla adasinthira Megapack kukhala ma cell a LFP a CATL ndikuwonjezera chitsimikizo mpaka zaka 15. Ntchito ya BYD ya 12.5 GWh ndi Saudi Electricity Company idapita LFP. CATL imanena kuti palibe zotentha zomwe zachitika pa 256 GWh zomwe zatumizidwa. Makampaniwa adavotera ndi zosankha zake zogula.
Koma zolemba zofananira zama chemistry zomwe zikuyandama zimaphonya zomwe zimayendetsa zisankho izi pamlingo wa polojekiti. Nambala za kachulukidwe ka mphamvu sizikuwuzani ngati kuyika kwanu kudzakwanira pazomwe mwapatsidwa. Zolemba za moyo wapaulendo sizimatengera njira zakuwonongeka zomwe mudzaziwona pansi pamikhalidwe yanu yogwirira ntchito. Kutentha kosindikizidwa komwe kumayambira sikumatanthauzira mwachindunji zomwe ozimitsa moto angafune.
Zenizeni-Zofufuza Zapadziko Lonse
Tidali ndi kasitomala wapa telecom chaka chatha cha NMC kuti tiyikepo zosunga zobwezeretsera chifukwa manambala amagetsi a omwe amapereka amawoneka bwino pamapepala. Kuyendera kwatsamba kukuwonetsa kuti afunika kuwonjezera mphamvu ya HVAC kuti azitha kutentha. Kuwotcha moto kumawonjezera nthawi yanthawi yayitali miyezi itatu. Ndalama zonse zomwe zidakhazikitsidwa zidabwera 22% kuposa njira ina ya LFP yomwe adakana poyamba. Maselo a NMC okha anali otsika mtengo pa kWh. Chirichonse chowazungulira iwo sichinali.
Chitsanzo ichi chikubwereza. Chigamulo cha batri chemistry chimagwera mumitengo ya BOS, kuloleza nthawi, zofunikira za inshuwaransi, ndi mapangano okonza. Magulu ogula zinthu amangoyang'ana kwambiri-zochulukira zama cell zomwe zaphonya machitidwewa-pamawonekedwe amtunduwu.
Pa moyo wozungulira, manambala ogulitsa manambala amayenera kuunikanso. "5,000 cycles to 80% capacity" imamveka molunjika mpaka mutapeza mayeso. Mtengo wa C-wotani? Kuya kwa kutulutsa kotani? Kutentha kotani? Selo yoyesedwa pa 0.5C ndi 25 digiri mu labu imachita mosiyana kwambiri ndi njinga imodzi pa 1C mumtsuko wotumizira ku Phoenix.
Zenizeni-zambiri zapadziko lonse lapansi ziyamba kuonekera. Bungwe la Electric School Bus Initiative linatsata mabasi 847 LFP-okhala ndi zida ndipo linawonetsa kuwonongeka kwa mphamvu ndi 7.2% pazaka zisanu zakugwira ntchito. Ndizo zabwino kuposa malingaliro ambiri a chitsimikizo. Magulu a NMC akuwonetsa kusiyana kwakukulu-ena akuimirira bwino, ena akudutsa malire a chitsimikizo msanga kuposa momwe amayembekezera. Ubwino wa ma cell ndi kasamalidwe ka matenthedwe ndizofunikira kwambiri kuposa lebulo la chemistry lomwe lili papepala.
Kusanthula kosungirako kwa gridi ya DOE 2020 kuyerekeza kuti LFP itenga nthawi yayitali 67% kuposa NMC pansi pamikhalidwe yofananira yopalasa njinga. Lofalitsidwa pa energy.gov. Njirayi imakondera ma protocol oyeserera, kotero kuti-kusiyana kwenikweni kwapadziko lonse lapansi kudzasiyana, koma mfundo yomaliza imagwira ntchito zambiri zomwe tatengera.
Kuchita kwanyengo yozizira ndipamene LFP imachepa kwenikweni, ndipo sikuti kungochepetsa mphamvu.
Kulipira LFP pansi pa 0 digiri kumayambitsa lithiamu plating pa anode. Sizinachedwe kugwira ntchito-kuwonongeka kosatha komwe kumachitika pakangozizira kozizira. Selo likuwoneka bwino. BMS ikhoza kuletsa chilichonse. Koma mukunyozetsa paketi nthawi zonse.
Njira zolipirira mafakitale zimayankha pophwanya mitengo yolipiritsa pamatenthedwe otsika. Pa -madigiri 10 , mtengo wololeka ukutsikira pafupifupi 0.02C. Maola makumi asanu ndi kuonjezera kuti mutenge ndalama zonse pamlingo umenewo. Mogwira unusable popanda kutentha yogwira.
Tanena mapulojekiti kumtunda kwa Midwest komwe oyang'anira kutentha adawonjezera 12-18% kumitengo yamakina. Mipanda yotsekeredwa, zinthu zotenthetsera, zowongolera. Adalembabe pensulo motsutsana ndi NMC pa TCO yazaka 10, koma kugunda kwa likulu la Chaka 1 kunali chenicheni ndipo kumafuna kusaina kwa akuluakulu kupyola bajeti yoyambirira.
Ngati kuyikira kwanu kuyenera kuzizira kwambiri-ndipo kutentha kwanu kuli kocheperachepera, NMC ikhoza kukhala yolondola ngakhale kukwera mtengo kwa moyo wanu. Talankhula ndi makasitomala ku NMC pazifukwa izi. Sikuti ntchito iliyonse iyenera kukhala LFP.
Pamitengo, kafukufuku wa BloombergNEF 2024-2025 akuwonetsa mtengo wa paketi pafupifupi $81/kWh pa LFP motsutsana ndi $128/kWh pa NMC. Koma mitengo yamapaketi satengera zomwe mudzalipira.
Mitengo yama cell a LFP yaku China idatsika pansi $50/kWh mpaka pakati-2024. Zogulitsa zina zamalo akuti zidatsekedwa pansi pa $40/kWh. Kuchulukirachulukira ndi kuchuluka kwenikweni kwa CATL ndi BYD patsogolo pakufunika, ndipo opanga ang'onoang'ono akuthetsa zida. Ngati mukugula voliyumu ndipo gulu lanu logula zinthu likudziwa kukambirana, zomwe zimasindikizidwa ndizokwera, osati pansi.
Kumbali: ma cell otsika mtengo ochokera kwa ogulitsa omwe ali ndi nkhawa nthawi zina amatanthauza kusiyana kwabwino. Tawona magulu okhala ndi mphamvu akufalikira mokulirapo kuposa ma spec. Mavuto a BMS calibration. Zolemba zomwe sizikugwirizana ndi zomwe zili m'bokosi. Maselo a $ 45/kWh omwe amafunikira 15% yowonjezera ntchito ya QC ndikupanga zonena za chitsimikizo samapulumutsa ndalama.
Maubale okhazikitsidwa ndi gulu-opereka katundu m'modzi (CATL, BYD, EVE, CALB a LFP; Samsung SDI, LG Energy Solution, SK On for NMC) amagulitsa phindu lina la mtengo wake kuti likhale lodalilika. Kulekerera kwanu pachiwopsezo ndi kuchuluka kwa magulidwe kumatsimikizira komwe mungafike pa sipekitiramuyo.
Kuwerengera mtengo wa Lifecycle kumafuna malingaliro okhudzana ndi kugwiritsidwa ntchito komwe kumasiyana malinga ndi ntchito.

Izi zimamasulira kukhala malo ogwiritsira ntchito pansi komanso mtengo wotsika wokonzekera malo.
Kuwongolera Mwalamulo ndi Zowopsa
Samalani za kuwonekera pazambiri komanso inshuwaransi. Ma inshuwaransi onyamula katundu alimbitsa kufalikira kwa batri ya lithiamu kwambiri kuyambira 2021- $ 1.2 biliyoni pakutayika kwamoto kwa ogwiritsa ntchito zinyalala ku US / Canada chaka chimenecho chokha. Chiwopsezo chocheperako cha LFP chocheperako chimatanthawuza mawu abwino kwa olemba ena. Ndikoyenera kuyang'ana ndi broker wanu kumayambiriro kwa ndondomekoyi.
Zachuma
Chimasamala zonse zomwe zili pamwambazi chifukwa zimakhudza mtengo wokwanira wa projekiti komanso chiopsezo-zobwezera zosinthidwa.
Mayeso a BYD a Blade Battery olowera msomali ndi oyenera kuwunikira pazokambirana zamkati. Zotsatira zosindikizidwa zikuwonetsa ma cell a LFP akufika madigiri a 30-60 popanda zochitika zotentha pansi pamikhalidwe yomwe idayambitsa kulephera kwachiwawa m'maselo a NMC. Kanema akupezeka patsamba lawo. Zothandiza pazokambirana za omwe ali nawo chifukwa chake njira "yotsika mtengo" ya NMC singakhale yotsika mtengo pambuyo powerengera zachitetezo.
Tekinoloje zomwe zikubwera ndizofunikira kuzitsata koma mwina siziyenera kuchedwetsa mapulojekiti omwe alipo.
LMFP (lithium manganese iron phosphate) imapereka 15-20% kuwongolera kachulukidwe kamphamvu kuposa LFP yokhazikika yokhala ndi chitetezo chofananira. CATL ndi BYD ali ndi mizere yopangira. Zitha kukhala zotanthawuza pakuyika kopanda malo mkati mwa miyezi 18-24.
Gulu la CATL la sodium-ion Naxtra, lomwe linakhazikitsidwa mu Epulo 2025, limatha kuthana ndi nyengo yozizira bwino kwambiri-90% yamagetsi ogwiritsidwa ntchito pa -40 degrees . Koma kuchuluka kwa LFP kunapangitsa kuti mitengo ya cell ikhale yotsika kwambiri kotero kuti mtengo wa sodium-ion udasanduka nthunzi. Kulera mochedwa kuposa momwe ananenera poyamba.
Dziko lolimba-likukhalabe 2027-2030 pazamalonda, mwachiyembekezo. Samsung SDI ndi Toyota alengeza nthawi, koma zovuta zopanga zinthu zikupitilirabe. Palibe chilichonse pama projekiti omwe akufotokozedwa lero.
Pakuyika komwe kukupita pansi pano, LFP yokhala ndi mitengo yamtengo wapatali komanso magwiridwe antchito ndiye chisankho chosungika pazamalonda ndi mafakitale ambiri. Njira yaukadaulo yomwe ikubwera ndi yosangalatsa koma siyisintha pafupi ndi-zisankho zanthawi yogula zinthu.
Kuyenerera kwa ogulitsa kumafunikanso monga kusankha chemistry.
Makampani ena omwe amagulitsa "mabatire a LFP" amagwira ntchito popanda kupanga. Akugula ma cell kwa aliyense amene ali ndi zida, kusonkhanitsa mapaketi ndi BMS iliyonse yomwe angapeze, ndikuyembekeza kuti zonena za chitsimikizo sizipitilira malire. Mitengo ikuwoneka yokongola. Thandizo pamene chinachake chalakwika ndi nkhani ina.
Kusamala koyenera kuchita: kafukufuku wa kufakitale kapena osachepera -lipoti loyendera gulu lachitatu. Kutsimikizira mphamvu zopanga. Kufufuza zachuma-kodi angapereke chitsimikizo cha zaka 10? Makasitomala otchulira omwe mungathe kuwayimbira. Zolemba za certification (UN38.3, UL1973, IEC62619) zomwe zimatsata ma cell omwe amakutumizirani, osati satifiketi yanthawi zonse kuchokera kwa omwe amawapatsira.
