Lithium bhatiri imhando yebhatiri rinoshandisa lithium simbi kana lithium alloy sechinhu chisina kunaka che electrode uye nonaqueous electrolyte solution. Lithium mabhatiri anonyanya kushandiswa muzvigadzirwa zvemadhijitari munharaunda yechinyakare, uye anonyanya kushandiswa mumunda wemabhatiri emagetsi uye kuchengetedza kwesimba muminda iri kubuda.
China ine zvakawanda zvelithium zviwanikwa uye yakazara lithium bhatiri indasitiri cheni, pamwe nehwaro hombe hwematarenda, zvichiita kuti China ive dunhu rinokwezva zvakanyanya mukusimudzira mabhatiri e-lithium uye indasitiri yezvigadzirwa, uye yave yakakura kwazvo pasi rose. Battery zvinhu uye bhatiri rekugadzira base. Kumusoro kweiyo lithium bhatiri indasitiri chain inosanganisira cobalt, manganese, nickel ore, lithium ore, uye graphite ore. Mune lithium bhatiri yekugadzira indasitiri chain, iyo yepakati chikamu chebhatiri pack ndiyo musimboti webhatiri. Mushure mekunge bhatiri core yaiswa mukati, iyo wiring harness nePVC firimu zvinosanganiswa kuita bhatiri module, uye ipapo waya yekubatanidza yekubatanidza uye BMS redunhu bhodhi inowedzerwa kuti igadzire simba rebhatiri chigadzirwa.
Upstream ongororo yeindasitiri chain
Kumusoro kwebhatiri re lithium ndiko kuchera uye kugadzirisa zviwanikwa, kunyanya lithium zviwanikwa, cobalt zviwanikwa uye graphite. Zvitatu zvekushandisa zvemagetsi zvemagetsi: lithium carbonate, cobalt uye graphite. Zvinonzwisiswa kuti pasi rose lithium resource reserves yakapfuma kwazvo, uye ikozvino 60% ye lithium zviwanikwa hazvina kuongororwa uye kugadzirwa, asi kugoverwa kwemigodhi yelithium kunenge kwakanyanyisa, kunyanya kugoverwa mu "lithium triangle" munharaunda yeSouth America. , Australia neChina.
Parizvino, nzvimbo dzepasi rose dzekuchera dzinenge 7 miriyoni matani, uye kugovera kwakawedzera. Nzvimbo dzakachengetwa dzeCongo (DRC), Australia neCuba dzinotora makumi manomwe muzana enzvimbo dzepasi rose, kunyanya matura eCongo emamiriyoni mazana matatu nemazana mana ematani, anodarika makumi mashanu muzana epasirese. .
Midstream ongororo yelithium bhatiri indasitiri
Pakati peiyo lithium bhatiri indasitiri chain inonyanya kusanganisira zvakasiyana-siyana zvakanaka uye zvisina kunaka zvinhu, pamwe ne electrolytes, tabo, diaphragms uye mabhatiri.
Pakati pavo, iyo lithium bhatiri electrolyte inotakura yekutyaira lithium ion mu lithium ion bhatiri, uye inoita basa rakakosha mukushanda nekuchengetedza kwe lithium bhatiri. Nheyo yekushanda yelithium-ion bhatiri zvakare inzira yekuchaja uye kuburitsa, ndiko kuti, iyo lithium ion inovharwa pakati peiyo yakanaka uye yakaipa electrode, uye iyo electrolyte ndiyo yepakati yelithium ion kuyerera. Basa guru re diaphragm nderokuparadzanisa magetsi akanaka uye asina kunaka ebheteri, kudzivirira matanda maviri kubva pakusangana uye pfupi-circuit, uyewo ane basa rekupfuura electrolyte ions.
Kudzika kwekuongorora kwe lithium bhatiri indasitiri chain
Muna 2018, kuburitswa kwemusika weChina welithium-ion bhatiri kwakawedzera ne26.71% gore-pa-gore kusvika 102.00GWh. Kugadzirwa kweChina kwepasirese kwakaverengera 54.03%, uye yave yakakura pasi rose lithium-ion bhatiri kugadzira. Lithium bhatiri anomiririra makambani ndeaya: Ningde era, BYD, Waterma, Guoxuan Hi-Tech uye zvichingodaro.
Kubva pamusika wekushandisa wakadzika welithium-ion mabhatiri muChina, bhatiri remagetsi muna 2018 raifambiswa nekusimudzira nekukurumidza kweindasitiri yemotokari yemagetsi. Kubuda kwakawedzera ne46.07% gore negore kusvika ku65GWh, iyo yakava chikamu chikuru; iyo 3C dhijitari bhatiri musika muna 2018 Kukura kwakagadzikana, uye kubuda kwakadzikira ne2.15% gore-pa-gore kusvika 31.8GWh, uye chiyero chekukura chakadzikira. Nekudaro, iyo yepamusoro-yekupedzisira yedhijitari bhatiri munda inomiririrwa nemabhatiri anochinjika, mabhatiri edhijitari yepamusoro uye yepamusoro-yekupedzisira dhijitari yakapfava packs inoiswa pasi pezvishandiso zvinopfekwa, drones, uye huchenjeri hwepamusoro. Inotungamirwa nezvikamu zvemusika senge nharembozha, yave chikamu chekukura-chepamusoro chemusika we3C bhatiri yedhijitari; muna 2018, mabhatiri eChina ekuchengetedza simba lithium-ion akawedzera zvishoma ne48.57% kusvika 5.2GWh.
