Chii chinonzi tembiricha bhatiri? Zvakanakira uye mabasa epasi-tembiricha lithium mabhatiri

Shamwari zhinji dzichava nemibvunzo padzinonzwa kuita kwekutanga kwemabhatiri ekudziya kwepasi: Chii chinonzi bhatiri rinodzikira? Pane chinobatsira here?

Chii chinonzi bhatiri rinodzikira?

Bhatiri rinodzika-tembiricha bhatiri rakasarudzika rakagadzirirwa kuderera-kukanganisa kunowanikwa mukuita kwemakemikari magetsi masosi. The kuderera-kupisa bhatiri inoshandisa VGCF uye activated carbon ine yakananga nzvimbo ye (2000±500)㎡/gasi rinowedzera, uye rinoenderana zvakanaka uye zvisina kunaka electrode zvinhu. Kunyanya maelectrolyte ane akakosha ekuwedzera anoiswa jekiseni kuti ave nechokwadi chepasi-tembiricha yekuburitsa basa rebhatiri rinopisa. Panguva imwecheteyo, kutonhora kwepamusoro Kuchinja kwehuwandu hwe24h pa 70 ℃ ndeye ≦0.5%, iyo ine kuchengetedzwa uye kuchengetedza mabasa ezvakajairwa lithium mabhatiri.

Mabhatiri ekudzika-kupisa anoreva mabhatiri e-lithium-ion ane tembiricha yekushanda iri pasi -40°C. Iwo anonyanya kushandiswa munzvimbo yemauto emuchadenga, midziyo yemotokari, tsvakiridzo yesainzi nekununura, kutaurirana kwemagetsi, kuchengetedzwa kweveruzhinji, zvemagetsi zvekurapa, njanji, ngarava, marobhoti, uye mamwe minda. Low-temperature lithium mabhatiri anorongedzerwa maererano nekuita kwavo kubuda: kuchengetedza simba, kuderera-kupisa kwelithium mabhatiri, uye chiyero-mhando yakaderera-yekupisa mabhatiri lithium. Zvinoenderana neminda yekushandisa, yakaderera-tembiricha lithium mabhatiri akakamurwa kuita yakaderera-tembiricha lithium mabhatiri ekushandiswa kwemauto uye maindasitiri akadzika-tembiricha lithium mabhatiri. Mamiriro ekushandisa ayo akakamurwa kuita matatu akatevedzana: mabhatiri echiuto akadzika-tembiricha, mabhatiri akasarudzika-akadzikama, uye yakanyanyisa-zvakatipoteredza-yakadzika-yekushisa mabhatiri.

Nzvimbo dzekushandisa dzemabhatiri ekudzikira kwakadzikira anonyanya kusanganisira zvombo zvehondo, aerospace, zvombo zvinotakurwa nemotokari, polar sainzi tsvagiridzo, kununura kwechando, kutaurirana nemagetsi, kuchengetedzwa kweveruzhinji, zvemagetsi zvekurapa, njanji, ngarava, marobhoti, uye zvimwe minda.

Zvakanakira uye mabasa epasi-tembiricha lithium mabhatiri

Low-temperature lithium mabhatiri ane zvakanakira kureruka, yakakwirira chaiyo simba, uye hupenyu hurefu uye anoshandiswa zvakanyanya mumhando dzakasiyana dzemagetsi. Pakati pavo, iyo yakaderera-inopisa yepolymer lithium-ion bhatiri inewo zvakanakira kurongedza zviri nyore, zviri nyore kushandura geometric chimiro chedutu, ultra-light uye ultra-thin, uye kuchengetedzwa kwepamusoro. Yakave iyo sosi yemagetsi kune akawanda enhare zvigadzirwa zvemagetsi.

Haikwanise kushandisa mabhatiri emunhuwo zvake pa -20°C, uye ichiri kukwanisa kushandisa mabhatiri e-lithium akadzikama, kazhinji pa -50°C. Parizvino, mabhatiri ekudzikira kwakadzikira anowanzo kushandiswa munzvimbo ye ℃ kana pasi. Pamusoro pemagetsi ekutaurirana, magetsi anotakurika echiuto, magetsi emagetsi madiki, uye midziyo yemagetsi madiki emagetsi zvinodawo kushandiswa kwemabhatiri akadzikama. Aya magetsi emagetsi anewo kuderera-kupisa kwekuita zvinodiwa kana uchishanda mumunda.

Mapurojekiti ekuongorora nzvimbo senge ndege yekubhururuka uye chirongwa chekumhara pamwedzi chiri kuitwa muChina chinodawo masimba emagetsi ekuchengetedza epamusoro-soro, kunyanya mabhatiri e-lithium akadzikama. Nekuti zvigadzirwa zvekutaurirana zvemauto zvine zvakaomarara zvinodiwa pahunhu hwebhatiri, kunyanya zvinoda vimbiso dzekutaurirana patembiricha yakaderera. Naizvozvo, kukudziridzwa kwemabhatiri e-lithium akadzika-tembiricha kwakakosha zvikuru mukuvandudzwa kwemauto uye maindasitiri emuchadenga.

Low-temperature lithium mabhatiri anoshandiswa zvakanyanya nekuda kwekureruka kwavo, yakakwirira chaiyo simba, uye hupenyu hurefu. Yakaderera-tembiricha lithium mabhatiri anogadzirwa emhando yakasarudzika uye maitiro uye akakodzera kushandiswa munzvimbo dzepasi-zero inotonhora.

Mainjiniya paYunivhesiti yeCalifornia, San Diego, vakabudirira kugadzira yakaderera-tembiricha lithium iron phosphate lithium-ion bhatiri remagetsi iro rinogona kuchengetedza mashandiro patembiricha yekamuri pane yakaderera tembiricha ye minus 60 ° C. Parizvino, mhando dzemabhatiri ekudzika-kupisa ayo anogona kuisa pamusika anonyanya kusanganisira yakaderera-kupisa lithium iron phosphate mabhatiri uye polymer low-temperature lithium mabhatiri. Aya marudzi maviri ekudzika-tembiricha ebhatiri tekinoroji akakura.

Zvimiro zvepasi-tembiricha lithium iron phosphate bhatiri

• Yakanakisa kuderera-kupisa kwekuita: kuburitsa pa 0.5C pa -40 ℃, simba rekuburitsa rinopfuura 60% yehuwandu hwekutanga; pa -35 ℃, yakaputika pa 0.3C, simba rekubudisa rinopfuura 70% yehuwandu hwekutanga;
• Wide kushanda tembiricha siyana, -40 ℃ kusvika 55 ℃;
• Kudzikira-kupisa lithium iron phosphate bhatiri ine 0.2c discharge cycle test curve pa -20°C. Mushure memazana matatu ekutenderera, kuchine huwandu hwekuchengetedza huwandu hunodarika 300%.
• Inogona kuburitsa curve yekuyerera yeyakadzika-tembiricha lithium iron phosphate mabhatiri pane akasiyana tembiricha pa -40 ° C kusvika 55 ° C.

Iyo yakaderera-tembiricha lithium iron phosphate bhatiri tekinoroji nyowani yakagadziridzwa mushure mekutsvaga kwenguva refu nekusimudzira uye kuyedzwa. Yakasarudzika inoshanda mbishi zvinhu zvinowedzerwa kune electrolyte. Izvo zvakanakisa zvekushandisa uye tekinoroji inoita kuti bhatiri rive nepamusoro-soro rekuburitsa mashandiro patembiricha isina kudzika. Iyi yakaderera-tembiricha lithium iron phosphate bhatiri inoshandiswa zvakanyanya munzvimbo dzakaderera-tembiricha dzakadai semidziyo yemauto, indasitiri yezvemuchadenga, midziyo yekunyungudika, polar sainzi kuongorora, kutaurirana kwemagetsi, kuchengetedzwa kweveruzhinji, zvemagetsi zvekurapa, nezvimwe.
