Ibhetri yeLithium (iLi-ion, iLithium Ion Battery): Iibhetri zeLithium-ion zineengenelo zobunzima obulula, amandla aphezulu, kunye nokungasebenzisi imemori, kwaye ke ngoko zisetyenziswa rhoqo - izixhobo ezininzi zedijithali zisebenzisa iibhetri zeLithium-ion njengomthombo wamandla, nangona zibiza kakhulu. Uxinano lwamandla lweebhetri zeLithium-ion luphezulu kakhulu, kwaye amandla alo aphindwe kayi-1.5 ukuya kweyesi-2 kunalawoIibhetri zeNiMHezinobunzima obufanayo, kwaye zinezinga eliphantsi kakhulu lokuzikhupha. Ukongeza, iibhetri ze-lithium-ion azinawo phantse “umphumo wenkumbulo” kwaye azinazo izinto ezinobuthi kwaye ezinye izibonelelo nazo zisizathu esibalulekileyo sokusetyenziswa kwayo ngokubanzi. Nceda uqaphele ukuba iibhetri ze-lithium zihlala ziphawulwe ngebhetri ye-4.2V lithium ion okanye ibhetri yesibini ye-4.2V lithium okanye ibhetri etshajwayo ye-4.2V lithium ion ngaphandle.

Ibhetri ye-lithium eyi-18650
I-18650 ngumsunguli webhetri ye-lithium-ion – yimodeli yebhetri ye-lithium-ion eqhelekileyo esekwe yinkampani yaseJapan i-SONY ukuze kongiwe iindleko, i-18 ithetha ububanzi be-18mm, i-65 ithetha ubude be-65mm, i-0 ithetha ibhetri ye-cylindrical. I-18650 ithetha ububanzi be-18mm, ubude be-65mm. Kwaye inombolo yemodeli yebhetri yeNombolo 5 yi-14500, ububanzi be-14 mm kunye nobude be-50 mm. Ibhetri ye-18650 iyonke isetyenziswa kakhulu kushishino, ukusetyenziswa kwabantu kuncinci kakhulu, kudla ngokusetyenziswa kwiibhetri zelaptop kunye neetotshi eziphezulu.

Iibhetri eziqhelekileyo ze-18650 zahlulwe zaba ziibhetri ze-lithium-ion, iibhetri ze-lithium iron phosphate. I-voltage yebhetri ye-lithium-ion ye-voltage eqhelekileyo ye-3.7v, i-voltage yokutshaja eyi-4.2v, ibhetri ye-lithium iron phosphate ye-3.2V, i-voltage yokutshaja eyi-3.6v, umthamo uhlala uyi-1200mAh-3350mAh, umthamo oqhelekileyo yi-2200mAh-2600mAh. Ithiyori yobomi bebhetri ye-lithium ye-18650 ye-cycle charging izihlandlo ezili-1000.

Ibhetri ye-18650 Li-ion isetyenziswa kakhulu kwiibhetri zelaptop ngenxa yomthamo wayo ophezulu ngeyunithi nganye yoxinano. Ukongeza, ibhetri ye-18650 Li-ion isetyenziswa kakhulu kwiindawo ze-elektroniki ngenxa yokuzinza kwayo okugqwesileyo emsebenzini: isetyenziswa kakhulu kwithotshi ephezulu, umbane ophathwayo, i-transmitter yedatha engenazingcingo, iimpahla ezifudumeleyo zombane kunye nezihlangu, izixhobo eziphathwayo, izixhobo zokukhanyisa eziphathwayo, iprinta ephathwayo, izixhobo zoshishino, izixhobo zonyango, njl. izixhobo zonyango, njl.

Ibhetri yeLi-ion ephawulwe nge-3.7V okanye nge-4.2V ziyafana. I-3.7V ibhekisa kwi-voltage yeqonga (oko kukuthi, i-voltage eqhelekileyo) ngexesha lokusetyenziswa kwebhetri ekhutshwayo, ngelixa i-4.2 volts ibhekisa kwi-voltage xa ​​itshaja itshaja epheleleyo. Ibhetri yeLithium eqhelekileyo etshajayo ye-18650, i-voltage iphawulwe nge-3.6 okanye nge-3.7v, i-4.2v xa itshaja ngokupheleleyo, engenanto yakwenza namandla (umthamo), umthamo webhetri ye-18650 ukusuka kwi-1800mAh ukuya kwi-2600mAh, (umthamo webhetri yamandla ye-18650 ubukhulu becala ukwi-2200 ~ 2600mAh), umthamo oqhelekileyo uphawulwe nge-3500 okanye i-4000mAh nangaphezulu.

Ngokwesiqhelo kukholelwa ukuba i-voltage engenamthwalo yebhetri ye-Li-ion iya kuba ngaphantsi kwe-3.0V kwaye umbane uya kusetyenziswa uphele (ixabiso elithile kufuneka lixhomekeke kwixabiso eliphakathi lebhodi yokukhusela ibhetri, umzekelo, ziphantsi njenge-2.8V, kukwakho ne-3.2V). Uninzi lweebhetri ze-lithium azinakukhutshwa kwi-voltage engenamthwalo ye-3.2V okanye ngaphantsi, kungenjalo ukukhupha okugqithisileyo kuya konakalisa ibhetri (iibhetri ze-lithium ezithengiswayo ngokubanzi zisetyenziswa nepleyiti yokukhusela, ngoko ke ukukhupha okugqithisileyo kuya kukhokelela ekubeni ipleyiti yokukhusela ingakwazi ukubona ibhetri, ngaloo ndlela ingakwazi ukutshaja ibhetri). I-4.2V ngumda ophezulu we-voltage yokutshaja ibhetri, ngokubanzi ithathwa njenge-voltage engenamthwalo yeebhetri ze-lithium ezitshaja kwi-4.2V kumbane. Inkqubo yokutshaja ibhetri igcwele, i-voltage yebhetri kwi-3.7V inyuka kancinci ukuya kwi-4.2V, ukutshaja ibhetri ye-lithium akunakutshaja ukuya kwi-voltage engaphezulu kwe-4.2V engenamthwalo, kungenjalo kuya konakalisa ibhetri, eyindawo ekhethekileyo yeebhetri ze-lithium.
