Kubva pakutanga kwezana ramakore rechi21, nekukwira kwemagetsi evatengi akadai sema smartphones, mahwendefa, zvinopfekwa nema drones, kudiwa kwelithium mabhatiriyaona kuputika kusati kwamboitika.Kudiwa kwepasi rose kwemabhatiri e-lithium kuri kukura pamwero we40% kusvika 50% gore rega rega, uye nyika yakagadzira majaja emotokari matsva anosvika bhiriyoni imwe nemazana maviri uye mabhatiri emagetsi anopfuura miriyoni emotokari dzemagetsi, makumi masere muzana kubva Chinese market.Sekureva kwaGartner data: Pakazosvika 2025, iyo yepasi rose lithium bhatiri huwandu huchasvika 5.7 bhiriyoni Ah, ine musanganiswa wepagore kukura kwe21.5%.Nekufambira mberi kwehunyanzvi uye kudzora mutengo, Li-ion bhatiri rave mutengo wemakwikwi kune echinyakare lead-asidhi bhatiri mune nyowani simba remagetsi bhatiri.
1.Technology Trends
Lithium bhatiri tekinoroji inoramba ichikura, kubva kune yakapfuura ternary zvinhu kusvika yakakwira simba density lithium iron phosphate zvinhu, iko zvino shanduko kune lithium iron phosphate uye ternary zvinhu, uye cylindrical process ndiyo yakanyanya.Mumunda wemagetsi evatengi, cylindrical lithium iron phosphate mabhatiri ari kutsiva echinyakare cylindrical uye square lithium iron phosphate mabhatiri;kubva kune simba bhatiri maapplication, kubva pakutanga kwekushandiswa kusvika nhasi, chikamu chesimba bhatiri application chiri kuwedzera gore negore maitiro.Ikozvino nyika dzepasirese dzepasirese simba bhatiri application reshiyo inosvika 63%, inotarisirwa kusvika 72% muna 2025. Mune ramangwana, nekufambira mberi kwetekinoroji uye kutonga kwemitengo, Lithium bhatiri chigadzirwa chimiro chinotarisirwa kugadzikana uye kupa musika wakafara. nzvimbo.
2.Market Landscape
Li-ion bhatiri ndiyo inonyanya kushandiswa mhando yebhatiri remagetsi uye ine huwandu hwakawanda hwemashandisirwo mumunda wemagetsi matsva mota, uye kudiwa kwemusika kweLi-ion bhatiri yakakura.Ah, kumusoro 44.2% gore-pa-gore.Pakati pavo, kugadzirwa kweNingde Times kwakaverengera 41.7%;BYD iri pachinzvimbo chechipiri, ine 18.9% yekugadzirwa.Nekuwedzera kuri kuramba kuchienderera mberi kwemabhizinesi ekugadzira hunyanzvi, maitiro emakwikwi erithium bhatiri indasitiri ari kuramba achiwedzera kutyisa, Ningde Times, BYD nemamwe mabhizinesi ari kuramba achiwedzera mugove wavo wemusika nekuda kwezvaakanakira, nepo Ningde Times yasvika muhukama hwehukama ne Samsung SDI uye yave imwe yevakawanda simba bhatiri vatengesi veSamsung SDI;BYD inoramba ichiwedzera mari yayo mumunda wemabhatiri emagetsi nekuda kwehunyanzvi hwayo hwakanakira, uye ikozvino iri muBYD's kugadzirwa kwesimba marongero mumunda wemabhatiri emagetsi zvishoma nezvishoma akavandudza uye akapinda muchikamu chekugadzira kukuru;BYD ine humbowo hwakadzama uye hwakadzama hwekumusoro-soro mbishi zvinhu lithium, yayo yakakwira nickel ternary lithium, graphite system zvigadzirwa zvakakwanisa kuzadzisa zvinodiwa nemakambani mazhinji ebhatiri relithium.
3.Lithium bhatiri chimiro chekuongorora
Kubva mukugadzirwa kwemakemikari, kune zvakanyanya cathode zvinhu (kusanganisira lithium cobaltate zvinhu uye lithium manganate zvinhu), negative electrode zvinhu (kusanganisira lithium manganate uye lithium iron phosphate), electrolyte (kusanganisira sulfate solution uye nitrate solution), uye diaphragm (kusanganisira LiFeSO4 uye LiFeNiO2).Kubva pakuita kwezvinhu, zvinogona kukamurwa kuita zvakanaka uye zvisina kunaka electrode zvinhu.Lithium-ion mabhatiri anowanzo shandisa cathode kunatsiridza kuchaja kushanda zvakanaka, nepo uchishandisa lithium sechinhu checathode;electrode yakaipa uchishandisa nickel-cobalt-manganese alloy;cathode zvinhu zvinonyanya kusanganisira NCA, NCA + Li2CO3 uye Ni4PO4, nezvimwewo;electrode yakaipa sebhatiri yeion mune cathode zvinhu uye diaphragm ndiyo inonyanya kukosha, hutano hwayo hunokanganisa zvakananga kushanda kwe lithium-ion mabhatiri.Kuti uwane yakakwira kuchaji uye kuburitsa chaiyo simba uye hupenyu hurefu, lithium inofanirwa kuve nekuita kwepamusoro uye hupenyu hurefu hunhu.Lithium electrodes yakakamurwa kuita yakasimba-nyika mabhatiri, mabhatiri emvura uye mabhatiri epolymer zvinoenderana nezvinhu, izvo masero emafuta epolymer ari tekinoroji akakura ane mutengo wakanakira uye anogona kushandiswa mumafoni uye mamwe emagetsi evatengi;yakasimba-nyika simba nekuda kwekuwanda kwesimba uye mutengo wakaderera wekushandisa, wakakodzera kuchengetedza simba uye mamwe minda;uye simba repolymer nekuda kwekudzikira kwesimba uye mutengo wakaderera asi mashoma frequency ekushandisa, akakodzera lithium bhatiri pack.Masero emafuta epolymer anogona kushandiswa mumafoni, malaptop uye makamera edhijitari;solid-state bhatiri tekinoroji parizvino iri mudanho rekuyedza.
4.Manufacturing process uye mari yekuongorora
Consumer electronics lithium mabhatiri anogadzirwa achishandisa high voltage masero, ayo anonyanya kuumbwa nezvinhu zvakanaka uye zvisina kunaka electrode uye diaphragm zvinhu.Kuita uye mutengo wezvinhu zvakasiyana-siyana zvekathode zvinosiyana zvakanyanya, apo kushanda kuri nani kwezvinhu zvecathode, kuderera kwemutengo, nepo kuderera kwekushanda kwezvinhu zvediaphragm, kunowedzera kudhura.Sekureva kweChina Indasitiri Information Network data inoratidza kuti vatengi vemagetsi lithium bhatiri yakanaka uye yakaipa electrode zvinhu zvinoita makumi mashanu muzana kusvika makumi matanhatu muzana emutengo wakakwana.Izvo zvinhu zvakanaka zvinonyanya kugadzirwa nezvinhu zvisina kunaka asi mutengo wayo unodarika 90%, uye nemutengo wakashata wemusika unowedzera, mutengo wechigadzirwa wakawedzera zvishoma nezvishoma.
5.Equipment inotsigira zvinodiwa nemidziyo
Kazhinji, lithium battery assembly midziyo inosanganisira jekiseni molding machine, laminating machine, uye inopisa yekupedzisa mutsara, etc. Injection molding machine: inoshandiswa kugadzira mabhatiri makuru e-lithium, anonyanya kushandiswa kuva nepamusoro-soro ye automation yegadziriro yegungano, paine chisimbiso chakanaka.Zvinoenderana nezvinodiwa zvekugadzira, inogona kuve yakashongedzerwa neinowirirana mold, kuitira kuti uone kuchekwa chaiko kwemidziyo yekurongedza (musimboti, zvinhu zvisina kunaka, diaphragm, nezvimwewo) uye envelopu.Stacking muchina: Chishandiso ichi chinonyanya kushandiswa kupa iyo stacking process yesimba lithium bhatiri, iro rinonyanya kuve nezvikamu zviviri zvakakura: kukurumidza kurongedza uye kukurumidza kutungamira.
