Uyini umehluko phakathi kuka-21700 no-18650?
- Usayizi nomthamo wamabhethri angama-21700 ahlukaniswe ikakhulukazi izigaba ezimbili: amabhethri e-lithium iron phosphate kanye namabhethri e-ternary lithium. Igobolondo elingaphandle liyisilinda segobolondo lensimbi elinobubanzi obungama-21mm nobude obungama-70mm. Umthamo ngokuvamile ungaphezu kuka-4000mAh. Amabhethri e-18650 nawo ahlukaniswe izigaba ezimbili: amabhethri e-lithium iron phosphate kanye namabhethri e-ternary lithium-ion. Ububanzi buyi-18mm, ubude bungu-65mm, futhi umthamo uvame ukuba ngu-2500-3600mAh.

Ukuminyana kwamandla kanye nempilo yebhethri Ngokwesisindo samandla, uma i-21700 kanye ne-18650 amabhethri enziwe ngezinto zokusetshenziswa zamakhemikhali ezifanayo, ukuminyana kwawo kwamandla kuyefana. Ngokuphambene nalokho, uma i-21700 ne-18650 ingakhiqizwanga ngezinto zokusetshenziswa zamakhemikhali ezifanayo, ukuminyana kwabo kwamandla kuzohluka. Isibonelo, ubukhulu beyunithi yevolumu yamandla wamabhethri e-lithium iron phosphate buphansi kunamabhethri e-ternary lithium. Ngokuphathelene nempilo yebhethri, uma i-21700 ne-18650 amabhethri ohlobo olufanayo, khona-ke amabhethri angu-21700 anomthamo omkhulu kanye nomthamo omkhulu kunamabhethri angu-18650, futhi amabhethri angu-21700 anganikeza impilo yebhethri ende. Uma i-21700 ne-18650 kuyizinhlobo ezahlukene zamabhethri, impilo yebhethri yabo cishe izoba seduze okufanayo, okungukuthi, amabhethri angu-18650 asebenzisa amabhethri aphezulu-energy-density, futhi umthamo webhethri wokukhiqizwa kwawo ungaba mkhulu, okungenzeka ukuthi isondele kumthamo wamabhethri we-lithium iron phosphate angu-21700.

Izimo zohlelo lokusebenza nokusebenzisa amabhethri angu-21700 kuvame ukusetshenziswa kumadivayisi adinga isitoreji samandla esiphezulu nempilo yebhethri ende, njengesipele esiphuthumayo samandla we-UPS wezimoto zikagesi namadivayisi amakhulu kagesi. Amabhethri angu-18650 asetshenziswa kakhulu kumadivayisi amancane njengamathoshi, izinto ezincane zikagesi kanye nezinye izimoto zikagesi.

Izindleko kanye nobunzima bokuthenga Ngebhethri elilodwa (ibhethri elilodwa), njengoba isikali sokukhiqiza samabhethri angu-21700 singase sibe sincane kunesamabhethri angu-18650, futhi esimweni sohlobo olufanayo lwamabhethri, amabhethri angu-21700 anomthamo owengeziwe futhi asebenzisa okuyisisekelo. izinto zokusetshenziswa kunamabhethri angu-18650, ngakho-ke izindleko zabo zokukhiqiza zizoba phezulu, okungase kuholele ebunzimeni obukhulu bokuthenga kanye namanani aphezulu kancane.

Umehluko phakathi kwenani lamaseli nenani lamaseli Njengoba ububanzi bebhethri engu-21700 bukhulu futhi bungakwazi ukuthwala umthamo owengeziwe, igobolondo elidingekayo nge-m2 ngayinye yebhethri engu-21700 lingaphansi kuka-33% kunebhethri le-18650, ngakho-ke izindleko zegobolondo ze-21700 ibhethri iphansi kunaleyo ye-18650. Ngesikhathi esifanayo, njengoba inani lamabhethri ane-Wh efanayo lincishiswa ngo-33%, isidingo sokujova uketshezi kanye nenqubo yokufaka uphawu nayo iyancipha. Esimeni sokwenza iphakethe lebhethri elikhulu, izindleko ziyancipha.

Imishini yokwakha nokusebenza kahle. Njengoba inani eliphelele lamabhethri lincipha, isidingo semishini yokwakha sincipha kakhulu, okuthuthukisa ukusebenza kahle nokunciphisa izindleko. Kafushane, umehluko phakathi kwamabhethri angu-21700 kanye no-18650 ikakhulukazi usayizi, umthamo, ukuminyana kwamandla, izimo zohlelo lokusebenza, ubunzima bokuthengwa kwezindleko, indawo yokuhlala yebhethri kanye nenani lebhethri, okokusebenza nokusebenza kahle, njll. Kubalulekile ukukhetha uhlobo lwebhethri olufanele ezidingweni ezithile zohlelo lokusebenza.
