Ibhethri ye-Lithium 18650 kanye nebhethri le-polymer yonke
Ake sikhulume nge-18650 namabhethri e-polymer namuhla!
Lapha, ake sibheke iseli yebhethri engu-18650. Ukwakheka kwayo kwangaphakathi kuhlanganisa inhlanganisela ye-electrode lithium enhle, i-electrolyte membrane phakathi, kanye nekhabhoni ye-electrode engalungile.
Manje amabhethri ajwayelekile angu-2000-3000mAh esizukulwane esilandelayo, i-Deronne, i-Samsung, i-Panasonic, i-Sanyo, i-LG, namanye amabhethri emakethe, impahla yangaphakathi ye-cathode isithuthukiswe ngokugcwele isuka ku-LiCoO2 yesizukulwane sokuqala se-lithium cobalt oxide yaya kokusetshenziswa kwe-ternary, Igama lamakhemikhali Yi-LiNi-Co-MnO2 nickel cobalt manganese.
Izinzuzo eziqondile: impilo yesevisi ende, ephephile, ukusebenza okungcono. Uma sikhuluma ngalokhu, amabhethri e-Prismatic square soft package ahlanganiswe nethebhulethi yeselula nawo enziwe ngezinto ze-LiNi-Co-MnO2 nickel-cobalt-manganese, kodwa ahlukile kumabhokisi e-Cylindrical angu-18650.
"Yonke i-polymer" ibhekisela ekusetshenzisweni kwe-polymer ukwakha inethiwekhi yejeli ngaphakathi kweseli bese ijova i-electrolyte ukuze yakhe i-electrolyte.
Nakuba amabhethri "awo wonke ama-polymer" esasebenzisa ama-electrolyte awuketshezi, inani lincane kakhulu, lithuthukisa kakhulu ukusebenza kokuphepha kwamabhethri e-lithium-ion.
Ngakolunye uhlangothi, amabhethri e-polymer abhekisela kumabhethri e-lithium-ion asebenzisa ifilimu yokupakisha ye-aluminium-plastic njengephakeji yangaphandle, eyaziwa ngokuthi amabhethri e-soft-pack. Le filimu yokupakisha iqukethe izendlalelo ezintathu: isendlalelo se-PP, isendlalelo se-Al, nesingqimba senayiloni. Ngenxa yokuthi i-PP nenayiloni ama-polymer, lokhu kubizwa ngokuthi ibhethri le-polymer.
Ake siqhathanise okuhle nokubi kwakho kokubili:
Intengo yamazwe ngamazwe ye-18650 imayelana ne-1USD/pcs. Uma ibalwa ngokuya nge-2Ah, iku-3RMB/Ah yonke indawo. Izindleko zamabhethri e-lithium e-polymer zingu-4RMB/Ah kumafekthri ama-cottage asezingeni eliphansi, 5~7RMB/Ah ebangeni elimaphakathi, nangaphezulu kuka-7RMB/Ah ekupheleni okumaphakathi nokuya phezulu.
I-SONY ibilokhu ifuna ukwenza amabhethri e-lithium-ion njengamabhethri e-alkaline. Kunamazinga athile embonini, njengamabhethri e-AA namabhethri e-AA, afanayo emhlabeni jikelele. Kodwa-ke, enye yezinzuzo ezibalulekile zamabhethri e-lithium-ion ukuthi angaklanywa ngokuya ngezidingo zamakhasimende, futhi ayikho indinganiso efanayo. Kuze kube manje, imboni yebhethri ye-lithium-ion inemodeli evamile ye-18650, kanti ezinye zisekelwe kumakhasimende. Usayizi wesidingo uklanywe.
Siyazi ukuthi ngaphansi kwezimo ezimbi kakhulu (njengokukhokhiswa ngokweqile, izinga lokushisa eliphezulu, njll.), amabhethri e-lithium-ion azoba nokusabela kwamakhemikhali anobudlova ngaphakathi futhi akhiqize igesi eningi. Ibhethri le-18650 lisebenzisa igobolondo lensimbi elinamandla athile. Lapho umfutho womoya wangaphakathi ufinyelela izinga elithile, igobolondo lensimbi lizoqhuma, kubangele ingozi embi yokuphepha.
Yingakho igumbi lapho ibhethri le-18650 lihlolwa ngokuvamile kufanele livikelwe izendlalelo, futhi akekho ongangena phakathi nokuhlolwa. Amabhethri e-polymer awanayo le nkinga, ngisho nasezimweni ezimbi kakhulu, ngenxa yamandla aphansi wefilimu yokupakisha; inqobo nje uma umfutho womoya uphakeme kancane, uzogqashuka futhi ngeke uqhume. Icala elibi kakhulu ukusha. Ngakho-ke mayelana nokuphepha, amabhethri e-polymer angcono kunamabhethri angu-18650.
18650 kanye namabhethri e-polymer womabili amabhethri e-lithium. Njengamanje, i-18650 isetshenziswa kabanzi emakethe ye-lithium iron phosphate, i-lithium manganate, ne-ternary. I-voltage ebizwa ngokuthi i-3.8V, futhi i-voltage ephezulu ingafinyelela ku-4.2V uma isetshenziswa. I-voltage ephansi ingafinyelela ku-2.5V, awukho umphumela wenkumbulo, futhi inkambu yokusetshenziswa ibanzi ngokuqhathaniswa. Amandla ezobuchwepheshe okukhiqizwa kwasekhaya nawo ayakwazi, futhi afanele ukukhiqizwa kwasekhaya. Amabhethri e-polymer engiwabonile ikakhulukazi amaphekhi athambile. Kunezinhlobo zamandla namandla. Izinto zifana ne-18650, ngaphandle kokuthi i-18650 iyigobolondo lensimbi engagqwali, futhi i-polymer iyigobolondo lefilimu ye-aluminium-plastic. Ifanele ukukhiqizwa kwezimboni nezokuthutha-ukunikezwa kwamandla.
Ngokuvamile, i-18650 kanye namabhethri e-polymer anezinzuzo zawo, futhi ikhwalithi yebhethri incike kubuciko bomkhiqizi.

phendula kungakapheli amahora angu-6, noma yimiphi imibuzo wamukelekile!
