Nekuda kwesimba idzva renyika, simba idzva rave simba remangwana repasi rose zvishoma nezvishoma, pamwe neremangwana reChina simba guru.Nekuvandudzwa kwesainzi uye tekinoroji muChina, lithium bhatiri, sesimba idzva, yaswedera pedyo nePeople's Daily life zvishoma nezvishoma uye yakashandiswa zvakanyanya uye zvakanyanya.Mune ramangwana, ichatsiva oiri uye nekupa mipiro yakakura mukusimudzira kwakasimba uye kuchengetedza kwezvakatipoteredza kwenyika.Tevere, tinoita sumo nezvechigadzirwa chedu- lithium bhatiri raunogona kuziva zvakawanda nezve zvigadzirwa zvedu.
Masero edu anonyanya kupihwa neSAMSUNG, LG, LISHEN uye mamwe ma brand anozivikanwa, saka, zvigadzirwa zvedu zvine mhando yepamusoro uye zvakachengeteka.Masero edu anonyanya kusanganisira 3.85V high pressure lithium cobalt cell, 3.7V lithium cobalt cell, 3.63V ternary lithium cell, 3.2V lithium iron phosphate cell.Maumbirwo avo ari cylindrical, sikweya uye asina kujairika uye anoshanda tembiricha mune yakajairika tembiricha -20 ~ 65 ℃, yakakwirira tembiricha -20 ~ 80 ℃, yakaderera tembiricha -40 ~ 65 ℃ uye yakafara tembiricha -40 ~ 80 ℃.
Kune matatu mashandisiro e lithium bhatiri: nyowani simba mota, kuchengetedza simba uye zvemagetsi zvevatengi.Kambani yedu haiburitse lithium bhatiri yemotokari nyowani simba, asi isu tinogona kugadzira lithium bhatiri kune mamwe mashandisiro.Kuwedzera kune yedu iripo lithium bhatiri zvigadzirwa, mainjiniya edu anogona kugadzira bhatiri zvinoenderana nezvinodiwa kana zvinodiwa nevatengi vedu.Pane mimwe misiyano pakati pe lithium bhatiri.Izvi zvinotevera rondedzero yakadzama.

Lithium cobaltate ndiyo yekutanga chizvarwa chekutengesa cathode zvinhu, iyo yakagadziridzwa zvishoma nezvishoma uye yakagadziridzwa mumakumi emakore ebudiriro.Inogona kutariswa seyakanyanya kukura cathode zvinhu zve lithium ion bhatiri.Lithium cobalt oxide ine mabhenefiti epamusoro ekuburitsa chikuva, yakakwira chaiyo kugona, kuita kwakanaka kwebhasikoro, nyore synthesis maitiro uye zvichingodaro.Lithium cobalt oxide ine nzvimbo mubhatiri diki, uko kuwanda kwehuwandu kwakakosha.Lithium cobaltate ichiri yakanakisa sarudzo yediki lithium bhatiri.
Lithium iron phosphate imwe yemidziyo yecathode inokwezva kutarisisa zvakanyanya parizvino.Hunhu hwayo hukuru hahuna zvinhu zvinokuvadza, mutengo wakaderera, kuchengetedzwa kwakanaka, uye hupenyu hwekutenderera kusvika ku10,000 nguva.Aya maitiro anoita kuti lithium iron phosphate zvinhu ikurumidze kuve hotspot yekutsvagisa, uye lithium iron phosphate bhatiri yakashandiswa zvakanyanya mumunda wemotokari dzemagetsi.
Ternary zvinhu izita rinozivikanwa re lithium nickel cobalt manganese oxide ine chimiro chakafanana ne lithium cobalt acid.Ichi chinyorwa chinogona kuenzana uye kudzorwa maererano nechaiyo simba, kudzokorodza, kuchengetedza uye mutengo.Kuwedzera kweiyo nickel yemukati kuchawedzera huwandu hwezvinhu, asi huchaita kuti kutenderera kuite kuwedzere.Kuvapo kwecobalt kunogona kuita kuti chimiro chezvinyorwa zvigadzikane, asi iyo yakakwirira inoderedza simba.Kuvapo kwemanganese kunogona kuderedza mutengo uye kugadzirisa mashandiro ekuchengetedza, asi iyo yakakwira inoparadza iyo yakaturikidzana chimiro chechinhu.Naizvozvo, ndiko kutariswa kweternary material research nekusimudzira kuwana hukama hwakaenzana pakati pezvinhu zvitatu kuti ukwidze kuita kwakazara.
Kazhinji, lithium cobalt acid inokodzera diki lithium bhatiri, lithium iron phosphate bhatiri yakachengeteka, hupenyu hurefu, kupisa kwakanyanya.Ternary lithium bhatiri ine huremu huremu, yakakwira mukuchaja kunyatsoita, yakaderera tembiricha kuramba, saka vese vane hunhu hwavo.
Zvigadzirwa zvedu zvakakamurwa kuita nzvimbo dzekushandisa: bhatiri rekuchengetedza simba, bhatiri remagetsi uye bhatiri revatengi.
Iyo yakazara chimiro che lithium bhatiri yakafanana, sezvakaratidzwa mumufananidzo uri pasi apa.Inoumbwa nezvikamu zvina: positive electrode material, negative electrode material, diaphragm uye electrolyte.Musiyano unonyanya kuratidzwa mukuita.
Consumer lithium-ion mabhatiri anonyanya kushandiswa munharembozha, anotakurika makomputa, digitaalinen makamera, digitaalinen makamera, nharembozha magetsi, matoyi emagetsi uye zvimwe zvigadzirwa zvemagetsi zvevatengi, zvinoti izvo zvinonzi "3C zvigadzirwa" lithium bhatiri masero uye modules, iyo huru. fomu rakakamurwa kuita cylindrical, square uye soft pack bhatiri.Nekuda kwehuwandu hwehuwandu hunodiwa hwemutengi lithium bhatiri, kuwanda kwesimba kwakakwira, lithium cobalt oxide uye ternary zvinhu seyakanaka electrode.
Simba bhatiri uye bhatiri rekuchengetedza simba zvinewo zvakasiyana zvinodiwa kune simba density uye zvimwe zvinhu.Parizvino, lithium iron phosphate uye ternary lithium bhatiri inoshandiswa mubhatiri remagetsi uye bhatiri rekuchengetedza simba.
| simba bhatiri | bhatiri rekuchengetedza simba | |
| application | Inonyanya kushandiswa mumotokari dzemagetsi, mabhasikoro emagetsi uye mamwe maturusi emagetsi | Inonyanya kushandiswa mupeak uye frequency modulation simba rekubatsira masevhisi, renewable simba grid yekubatanidza, micro grid, C uye mamwe minda. |
| kuita zvinodiwa | Senharembozha yemagetsi, ine zvakakwirira zvinodikanwa zvesimba density uye simba density | Mazhinji emagetsi ekuchengetedza magetsi haadi kufambiswa, saka simba rekuchengetedza lithium bhatiri harina zvakananga zvinodikanwa zvesimba density.Simba density: akasiyana ekuchengetedza simba mamiriro ane zvakasiyana zvinodiwa;Panyaya yezvishandiso zvebhatiri, kutariswa kunofanirwa kubhadharwa pakuwedzera kwekuwedzera, kuwanda kwesimba, kushanda kwakafanana kwezvinhu zve electrode, nezvimwewo kuitira kuti utevere hupenyu hurefu hwekutenderera uye mutengo wakaderera weiyo yese simba rekuchengetedza midziyo. |
| cycle life | 1000-2000 nguva | 3500 nguva |
Zvigadzirwa zvedu zvakakamurwa kuita aluminium shell lithium bhatiri, simbi shell lithium bhatiri uye nyoro pack lithium bhatiri nekunze kurongedza zvinhu.
Sezvo iyo yakapfava pack lithium bhatiri inoshandisa aluminium-plastiki firimu kurongedza, iyo yakapfava pack lithium bhatiri kazhinji haizoputika kana iri njodzi yekuchengetedza, chete bulge kana kuputika.Inenge 20% yakareruka kupfuura aluminium shell bhatiri, uye inosvika 5 ~ 10% yepamusoro kugona kupfuura aluminium shell bhatiri.Uye zvakare, yakapfava pack lithium bhatiri ine yakaderera yemukati kuramba uye yakareba kutenderera hupenyu, yakanyatsokodzera inotakurika, inoda nzvimbo yakakwirira kana ukobvu maapplication, senge 3C yevatengi zvemagetsi.
Aluminium shell lithium bhatiri ine yakakwira chaiyo simba, chaiyo modulus, kutsemuka kuomarara, kuneta simba uye corrosion kuramba kugadzikana.Aluminium alloy material yakaderera density hunhu, isiri-magnetic, yakagadzikana alloy pane yakaderera tembiricha pane iyo magineti kuramba idiki, yakanaka kusimba kwemhepo uye iyo inokonzerwa nemwaranzi inoora nekukurumidza, saka yakashandiswa zvakanyanya mukubhururuka nendege, aerospace, zvitima zvinomhanya. kugadzira michina, yekufambisa uye indasitiri yemakemikari.
Iko kugadzikana kwemuviri uye kumanikidza kuramba kwesimbi lithium bhatiri yakakwira zvakanyanya kupfuura iyo yealuminium shell material bhatiri.Mushure mevagadziri vekambani yedu kugadzira chimiro chakagadziridzwa, mudziyo wekuchengetedza wakaiswa mukati mebhatiri yemukati, uye kuchengetedzeka kwesimbi shell column lithium bhatiri yasvika pahurefu hutsva.
Mushure mekusuma pamusoro, iwe unofanirwa kuve nekunzwisisa kwakadzama kweyedu lithium bhatiri.Tarisira kuti utitane nesu nekukurumidza sezvinobvira, tinoshandisa simba uye chiito kukuudza kuti takavimbika, zvigadzirwa zvedu uye masevhisi achaita kuti iwe ugutsikane kwazvo.Tarisira kushanda pamwe newe, ndatenda!
