Chiisimbi yelithiumbhatiri? Nhanganyaya yekushanda uye zvakanakira bhatiri resimbi re lithium

Bhatiri resimbi reLithium imhando yebhatiri iri mumhuri yebhatiri reLithium. Zita rayo rakazara ibati reLithium iron phosphate lithium ion. Cathode inyaya yeLithium iron phosphate. Nekuti mashandiro ayo anonyanya kukodzera kushandiswa kwesimba, inonziwo "lithium iron power battery". (inozonzi "lithium iron battery")

Nheyo yekushanda kwebhatiri resimbi re lithium (LiFePO4)
Maumbirwo emukati mebhatiri reLiFePO4: LiFePO4 ine chimiro cheolivine kuruboshwe inoshandiswa sedanda rakanaka rebhatiri, iro rakabatana nealuminium foil nedanda rakanaka rebhatiri. Pakati pane polymer diaphragm, iyo inoparadzanisa danda rakanaka kubva padanda rakanaka. Zvisinei, lithium ion Li+ inogona kupfuura asi electronic e – haigone kupfuura. Kurudyi kune danda rakanaka rebhatiri rine kabhoni (graphite), iro rakabatana necopper foil nedanda rakanaka rebhatiri. Electrolyte yebhatiri iri pakati pemagumo epamusoro neapasi ebhatiri, uye bhatiri rakavharwa negoko resimbi.

Kana bhatiri reLiFePO4 rachajwa, lithium ion Li+ iri mu positive electrode inotama ichienda ku negative electrode kuburikidza ne polymer membrane; Munguva yekubuda, lithium ion Li+ iri mu negative electrode inotama ichienda ku positive electrode kuburikidza ne diaphragm. Bhatiri reLithium-ion rinotumidzwa zita rekuti lithium ions inotama panguva yekuchajwa nekuburitswa.

Kushanda kukuru kwebhatiri reLiFePO4
Voltage yeLiFePO4 inonzi 3.2 V, voltage yekuchaja yekupedzisira ndeye 3.6 V, uye voltage yekuburitsa yekupedzisira ndeye 2.0 V. Nekuda kwemhando dzakasiyana uye maitiro emidziyo ye electrode yakanaka neisina kunaka uye electrolyte inoshandiswa nevagadziri vakasiyana-siyana, mashandiro avo achasiyana zvishoma. Semuenzaniso, kugona kwebhatiri remhando imwe chete (bhatiri rakajairika riri mupakeji imwe chete) kwakasiyana zvakanyanya (10% ~ 20%).

Zvakanakira zvebhatiri resimbi re lithium
Kana tichienzanisa nemabhatiri echinyakare ane lead-acid, mabhatiri e lithium-ion ane zvakanakira zvikuru mukushanda kwemagetsi, kuwanda kwesimba, hupenyu hwekufamba, nezvimwewo. Kana tichienzanisa nebhatiri rechinyakare rine lead-acid, rine zvakanakira zvinotevera: kuwanda kwesimba, kuchengetedzeka kwakasimba, kushanda zvakanaka kwekupisa kwepamusoro, simba rinobuda zvakanyanya, hupenyu hwekufamba kwenguva refu, huremu hwakareruka, kuchengetedza mari yekusimbisa imba yemuchina, saizi diki, hupenyu hwebhatiri hurefu, kuchengetedzeka kwakanaka, nezvimwewo.
