Ibhetri ye-Lithium 18650 kunye nebhetri yonke yepolymer

Ibhetri ye-Lithium 18650 kunye nebhetri yonke yepolymer

Masithethe nge18650 kunye neebhetri zepolymer namhlanje!

Apha, makhe sijonge kwi-18650 yebhetri yeseli. Isakhiwo sayo sangaphakathi siquka i-electrode positive lithium compound, i-membrane ye-electrolyte phakathi, kunye ne-carbon electrode negative.

Ngoku umgangatho we-2000-3000mAh ibhetri yesizukulwana esilandelayo, i-Deronne, i-Samsung, i-Panasonic, i-Sanyo, i-LG, kunye nezinye iibhetri kwimarike, izinto zangaphakathi ze-cathode ziphuculwe ngokupheleleyo ukusuka kwisizukulwana sokuqala se-LiCoO2 lithium cobalt oxide ukuya kwi-ternary material, Igama lekhemikhali YiLiNi-Co-MnO2 nickel cobalt manganese.

Izibonelelo ezithe ngqo: ubomi benkonzo ende, ikhuselekile, ukusebenza ngcono. Ukuthetha ngale nto, iibhetri zePrismatic square ezithambileyo ezipakishwe ngefowuni yeselula zenziwe ngeLiNi-Co-MnO2 nickel-cobalt-manganese imathiriyeli, kodwa yahlukile kwiibhokisi ze-Cylindrical ze-18650.

"Yonke i-polymer" ibhekisela ekusebenziseni i-polymer ukwenza inethiwekhi yejeli ngaphakathi kweseli kwaye ifake i-electrolyte ukwenza i-electrolyte.

Nangona "zonke iibhetri zepolymer" zisasebenzisa i-electrolyte engamanzi, isixa sincinci kakhulu, siphucula kakhulu ukusebenza kokhuseleko lweebhetri ze-lithium-ion.

Ukusuka komnye umba, iibhetri zepolymer zibhekisa kwiibhetri ze-lithium-ion ezisebenzisa ifilimu yokupakisha ye-aluminium-plastiki njengepakethe yangaphandle, eyaziwa ngokuba ziibhetri ezithambileyo. Le filimu yokupakisha iquka iileya ezintathu: umaleko wePP, umaleko weAl, kunye nomaleko wenayiloni. Ngenxa yokuba iPP kunye nenayiloni ziipholima, oku kubizwa ngokuba yibhetri yepolymer.

Makhe sithelekise iingenelo kunye nokungalunganga kwezi zimbini:

1. Price

Ixabiso lamazwe ngamazwe le-18650 li malunga ne-1USD / pcs. Ukuba ibalwe ngokwe-2Ah, ikuyo yonke indawo 3RMB/Ah. Iindleko zeebhetri ze-lithium ze-polymer yi-4RMB / Ah kwiifektri ze-cottage ezisezantsi, i-5 ~ 7RMB / Ah kuluhlu oluphakathi, kwaye ngaphezu kwe-7RMB / Ah kwi-middle-to-high end.

2. Ngaba inokwenziwa ngokwezifiso

I-SONY ibisoloko ifuna ukwenza iibhetri ze-lithium-ion njengeebhetri ze-alkaline. Kukho imigangatho yeshishini elithile, njengeebhetri ze-AA kunye neebhetri ze-AA, ezifanayo kwihlabathi jikelele. Nangona kunjalo, enye yeenzuzo ezibalulekileyo zeebhetri ze-lithium-ion kukuba zinokuyilwa ngokweemfuno zabathengi, kwaye akukho mgangatho ofanayo. Ukuza kuthi ga ngoku, imboni yebhetri ye-lithium-ion inomzekelo oqhelekileyo we-18650, kwaye ezinye zisekelwe kubathengi. Ubungakanani bemfuno yenzelwe.

3. ukhuseleko

Siyazi ukuba phantsi kweemeko ezigqithisileyo (ezifana nokugqithisa, ukushisa okuphezulu, njl.), iibhetri ze-lithium-ion ziya kuba neekhemikhali ezinobundlobongela ngaphakathi kwaye zivelise igesi eninzi. Ibhetri ye-18650 isebenzisa iqokobhe lentsimbi elinamandla athile. Xa uxinzelelo lomoya lwangaphakathi lufikelela kwinqanaba elithile, igobolondo lensimbi liya kuqhuma, libangele ingozi embi yokhuseleko.

Yingakho igumbi apho ibhetri ye-18650 ivavanywa ngokubanzi kufuneka ikhuselwe ngamanqwanqwa, kwaye akukho mntu unokungena ngexesha lovavanyo. Iibhetri zePolymer azinayo le ngxaki, nakwiimeko ezinzima, ngenxa yamandla aphantsi efilimu yokupakisha; ukuba nje uxinzelelo lomoya luphezulu kancinci, luya kugqabhuka kwaye aluyi kuqhushumba. Eyona meko imbi kakhulu kukutsha. Ke ngokokhuseleko, iibhetri zepolymer zingcono kuneebhetri ze18650.

I-18650 kunye neebhetri ze-polymer zombini iibhetri ze-lithium. Okwangoku, i-18650 isetyenziswa ngokubanzi kwimarike ye-lithium iron phosphate, i-lithium manganate, kunye ne-ternary. I-voltage ye-nominal yi-3.8V, kwaye i-voltage ephezulu inokufikelela kwi-4.2V xa isetyenziswa. I-voltage ephantsi inokufikelela kwi-2.5V, akukho mpembelelo yememori, kwaye indawo yokusetyenziswa ibanzi. Amandla obugcisa bemveliso yasekhaya nawo ayakwazi, kwaye afanelekile kwimveliso yasekhaya. Iibhetri zepolymer endizibonileyo ziipakethi ezithambileyo. Kukho iintlobo zamandla kunye nomthamo. Izinto eziphathekayo zifana ne-18650, ngaphandle kokuba i-18650 yigobolondo yensimbi engenasici, kwaye i-polymer yigobolondo yefilimu ye-aluminium-plastiki. Ifanelekile kwimveliso yezoshishino kunye nokuthutha-ukunikezelwa kwamandla.

Ngokubanzi, i-18650 kunye neebhetri ze-polymer zineenzuzo zazo, kwaye umgangatho webhetri uxhomekeke kubugcisa bomenzi.
