Cathode zvinhu kuongorora

Muna 2012, mabhatiri e lithium akaverengera 41% yepasi rose lithium terminal inoda. Iko kupinza uye kubuda kwekuita kwe lithium bhatiri kunoenderana nechimiro uye kuita kwe data yemukati yebhatiri. Ruzivo rwemukati rwebhatiri runosanganisira ruzivo rwakashata, electrolyte, membrane uye ruzivo rwakanaka. Positive data ndiyo yakakosha ruzivo, inoverengera 30-40% yemutengo welithium mabhatiri. Kukurumidza kuwedzera kwezvitoro zvemagetsi zvevatengi (malaptops, mahwendefa, mafoni efoni, nezvimwewo) kwakonzera kuwedzera kwekudiwa kwemabhatiri e lithium. Mune ramangwana, motokari dzemagetsi uye zvidyarwa zvekuchengetedza simba mune itsva simba chikamu zvichavimbawo ne lithium mabhatiri. Pakazosvika 2013, iyo yepasi rose lithium bhatiri indasitiri inotarisirwa kusvika 27.81 bhiriyoni US madhora. Muna 2015, kushandiswa kwemaindasitiri kwemotokari nyowani dzemagetsi kuchatyaira indasitiri yepasi rose yebhatiri yetimu kuti isvike US$52.22 bhiriyoni. Nekuwedzera kweiyo lithium bhatiri indasitiri chirongwa, Positive Data’s lithium bhatiri indasitiri chirongwa chiri zvakare mukukurumidza kuwedzera nhanho, uye kushandiswa kwe lithium cobalt oxide ndiko kwakanyanya kukura.

Shandisa chikamu chekuparara nedata rakanaka

Iyo yakanaka data ye lithium mabhatiri ari kushandiswa uye akagadziridzwa anonyanya kuumbwa ne ternary data ye lithium cobalt acid, lithium nickel cobalt acid, nickel manganese cobalt, spinel lithium manganese acid uye olivine lithium iron phosphate. Munyika yangu, data yecathode inonyanya kusanganisira lithium cobalt oxide, ternary data, lithium manganate uye lithium iron phosphate. Kuparara kwechikamu chekushandisa kwe data yakanaka kune kukosha kukuru. Lithium cobalt oxide ichiri kwakakosha sosi yedata yakanaka yemabhatiri madiki e-lithium, uye zvakare ine kukosha kukuru kune echinyakare 3C lithium mabhatiri. Ternary data uye lithium manganese oxide zvikamu zvakakosha zvemabhatiri eti lithium. MuJapan neSouth Korea, tekinoroji yebhatiri yakakura uye yakakosha kumidziyo yemagetsi, mabhasikoro emagetsi uye mota dzemagetsi. Lithium iron phosphate inoshandiswa zvakanyanya munyika yangu uye ndiyo nzira yebudiriro yeramangwana. Iyo ine yakakosha kukosha kwekushandisa muminda ye base station uye data center simba rekuchengetedza, imba yekuchengetedza simba, uye solar simba rekuchengetedza.

Lithium cobalt oxide ichatsiviwa zvishoma nezvishoma

Iyo yekugadzira nzira yelithium cobalt oxide iri nyore, iyo electrochemical performance yakagadzikana, uye ndiyo imwe yekutanga mabhenefiti ekutengesa kwakazara. Iyo ine mabhenefiti eyakakwira discharge voltage, yakagadzikana charge uye discharge voltage, uye yakakwirira simba reshiyo. Iine zvakakosha maapplication mudiki mabhatiri evatengi zvigadzirwa. Musika wemagetsi wevatengi uri kusimukira nekukurumidza, uye kutengeswa kwelithium cobalt oxide bhatiri cathode zvinhu zvinoverengera chikamu chikuru, asi mari yepamusoro haikodzeri kuchengetedza kwezvakatipoteredza, huwandu hwekushandisa huwandu hwakaderera, hupenyu hwebhatiri hupfupi, uye kuchengeteka kwakaipa. Ternary data inobatanidza zvakanakira lithium cobalt, lithium nickel uye lithium manganese uye ine mutengo wepamusoro, asi kushandiswa kwayo kunokonzerwa nemutengo wekobalt. Kana mutengo wecobalt wakakwira, mutengo we ternary data wakaderera pane wecobalt lithium, ine kukwikwidza kwakasimba kwemusika. Asi kana mutengo wecobalt wakadzikira, mukana weiyo triad data ine chekuita necobalt uye lithium idiki zvakanyanya. Parizvino, kutsiva kwe lithium oxide data ne ternary data inzira yakajairika.

Ternary data ine mukana wemutengo wakaderera

Iyo ternary data inogadzirwa nekuunza nickel, cobalt, uye manganese mune imwe chikamu, uyezve kuunza lithium sosi. Motokari yekutanga yeTesla yemitambo yakashandisa 18650 lithium cobalt oxide mabhatiri, nepo yechipiri yekugadzira modhi Model-s yakashandisa Panasonic’s customized Ternary-Data bhatiri, iri nickel-cobalt-aluminium bhatiri. Ternary-PositiveData bhatiri. Lithium cobalt oxide mabhatiri anodhura, saka zvine musoro kuenzanisa kuita kwemhando mbiri pamberi uye mushure meTesla. Model s inoshandisa anopfuura 8,000 mabhatiri, ayo anopfuura 1,000 kupfuura Roadster. Zvisinei, nekuda kwekutonga kuri nani kwebheteri ye-3-nzira, mari yacho yakaderedzwa ne30%. Parizvino, pachine mukaha mukuru pakati penyika yangu yepamusoro-inoshanda lithium bhatiri NCM ternary data uye musika wepasi rose, uye pane zvipingamupinyi zviviri zvikuru mumidziyo uye kugadzikana kwekudzora tekinoroji, uye budiriro iri pachena iri kusarira kumashure. Yakashandiswa zvakanyanya kunze kwenyika, asi kambani yedu haisati yave nezvigadzirwa.
