Ibhetri yeLithium (iLi-ion, ibhetri yeLithium ion): Iibhetri ze-Lithium-ion zineenzuzo zobunzima bokukhanya, umthamo ophezulu, kwaye akukho mpembelelo yememori, kwaye ngoko isetyenziswa ngokuqhelekileyo - izixhobo ezininzi zedijithali zisebenzisa iibhetri ze-lithium-ion njengomthombo wamandla, nangona zibiza kakhulu. Ubuninzi bamandla ebhetri ye-lithium-ion buphezulu kakhulu, kwaye umthamo wayo u-1.5 ukuya ku-2 amaxeshaIibhetri zeNiMHzobunzima obufanayo, kwaye unezinga eliphantsi kakhulu lokuzikhupha. Ukongeza, iibhetri ze-lithium-ion phantse azinayo "impembelelo yememori" kwaye aziqukethe izinto ezinobuthi kunye nezinye iingenelo zikwasisizathu esibalulekileyo sokusetyenziswa kwayo ngokubanzi. Nceda uqaphele kwakhona ukuba iibhetri ze-lithium zivame ukuphawulwa nge-4.2V ibhetri ye-lithiumion okanye i-4.2V ibhetri ye-lithium yesibini okanye i-4.2V ibhetri ye-lithiumion etshajwayo ngaphandle.

18650 lithium ibhetri
I-18650 ngumsunguli webhetri ye-lithium-ion - imodeli yebhetri ye-lithium-ion eqhelekileyo ebekwe yinkampani yaseJapan yaseSONY ukuze kugcinwe iindleko, i-18 ithetha ububanzi be-18mm, i-65 ithetha ubude be-65mm, i-0 ithetha ibhetri ye-cylindrical. 18650 kuthetha, 18mm ububanzi, 65mm ubude. Kwaye inombolo yemodeli yeNombolo ye-5 ibhetri yi-14500, i-14 mm ububanzi kunye no-50 mm ubude. Ibhetri ye-18650 ngokubanzi isetyenziswa kakhulu kushishino, ukusetyenziswa koluntu kuncinci kakhulu, okuqhelekileyo kusetyenziswa kwiibhetri zelaptop kunye nezibane eziphezulu.

Iibhetri eziqhelekileyo ze-18650 zihlulwe kwiibhetri ze-lithium-ion, iibhetri ze-lithium iron phosphate. Umbane webhetri ye-Lithium-ion kumbane oqhelekileyo we-3.7v, ukutshaja ombane onqunyiweyo we-4.2v, ibhetri ye-lithium ye-phosphate ibhetri ye-3.2V, ukutshaja umbane osikiweyo we-3.6v, umthamo udla ngokuba yi-1200mAh-3350mAh, umthamo oqhelekileyo. yi 2200mAh-2600mAh. I-18650 ithiyori yobomi bebhetri ye-lithium yentlawulo yomjikelo ngamaxesha angama-1000.

Ibhetri ye-18650 ye-Li-ion isetyenziswa kakhulu kwiibhetri zelaptop ngenxa yomthamo wayo ophezulu kwiyunithi nganye yokuxinana. Ukongeza, ibhetri ye-18650 ye-Li-ion isetyenziswa ngokubanzi kwiindawo ze-elektroniki ngenxa yokuzinza kwayo okuhle kakhulu emsebenzini: isetyenziswa ngokuqhelekileyo kwi-flashlight ephezulu, umbane ophathwayo, i-wireless data transmitter, iimpahla ezifudumele zombane kunye nezihlangu, izixhobo eziphathekayo, izixhobo zokukhanyisa eziphathekayo. , umshicileli ophathwayo, izixhobo zoshishino, izixhobo zonyango, njl. izixhobo zonyango, njl.

Ibhetri ye-Li-ion ephawulwe 3.7V okanye 4.2V ziyafana. I-3.7V ibhekisela kumbane weqonga (oko kukuthi, i-voltage eqhelekileyo) ngexesha lokusetyenziswa kwebhetri yokukhupha, ngelixa i-4.2 volts ibhekisela kumbane xa utshaja intlawulo epheleleyo. Common rechargeable 18650 lithium ibhetri, ombane iphawulwe 3.6 okanye 3.7v, 4.2v xa ihlawulwe ngokupheleleyo, nto leyo incinci ukwenza ngamandla (umthamo), 18650 ibhetri mainstream umthamo ukusuka 1800mAh ukuba 2600mAh, (18650 amandla ebhetri umthamo ubukhulu becala 2200 ~ 2600mAh), umthamo oqhelekileyo uphawuleka 3500 okanye 4000mAh okanye ngaphezulu ziyafumaneka.

Ngokuqhelekileyo kukholelwa ukuba i-voltage ye-no-load ye-Li-ion ibhetri iya kuba ngaphantsi kwe-3.0V kwaye umbane uya kusetyenziswa (ixabiso elithile lixhomekeke kwixabiso lomgubasi webhodi yokukhusela ibhetri, umzekelo, kukho ephantsi njenge-2.8V, kukho kwakhona i-3.2V). Uninzi lweebhetri ze-lithium azikwazi ukukhutshelwa kwi-voltage engekho yomthwalo we-3.2V okanye ngaphantsi, ngaphandle koko ukukhutshwa ngokugqithiseleyo kuya kuyonakalisa ibhetri (imarike jikelele iibhetri ze-lithium zisetyenziswa ngokusisiseko ngepleyiti yokukhusela, ngoko ke ukukhutshwa ngokugqithiseleyo kuya kukhokelela kwiplate yokukhusela. awukwazi ukubona ibhetri, ngoko ke awukwazi ukutshaja ibhetri). I-4.2V ngowona mda uphezulu wevoltheji yokutshaja ibhetri, ngokuqhelekileyo ithathwa njengombane ongenamthwalo webhetri ye-lithium ehlawulwe ukuya kwi-4.2V kumbane ogcweleyo, inkqubo yokutshaja ibhetri, amandla ombane ebhetri kwi-3.7V anyuka ngokuthe ngcembe aye kwi-4.2V, i-lithium. ukutshaja ibhetri ayinakuhlawuliswa ngaphezu kwe-4.2V i-voltage engalayishwanga, ngaphandle koko iya kulimaza ibhetri, eyona ndawo ikhethekileyo yeebhetri ze-lithium.

Iingenelo
