Ukuqonda kwangaphambili iibhetri ze-lithium
Wamkelekile kwibhlog esemthethweni yeHeltec Energy! Iibhetri zeLithium-ion ziye zaba yinxalenye ebalulekileyo yobomi bethu bemihla ngemihla, izixhobo zombane esizixhomekeke kuzo, ezifana neefowuni eziphathwayo kunye neelaptop, kwaneemoto. Uhlobo lwebhetri lwasungulwa ngasekupheleni kwenkulungwane ye-18, kwaye sele kudlule iminyaka engaphezu kwamakhulu amabini ukusukela ngoko. Iibhetri zeLithium-ion zezinye zeentlobo ezintsha zeebhetri ezizelwe kwinkqubo yophuhliso lwebhetri.
Iibhetri zahlulwe zibe ziibhetri ezomileyo ezinokusetyenziswa kube kanye kuphela, "iibhetri eziphambili", kunye neebhetri ezinokutshajwa zisetyenziswe amaxesha amaninzi, "iibhetri zesibini". Iibhetri zeLithium-ion ziibhetri zesibini ezinotshajwa. Xa kuthelekiswa nezinye iintlobo zeebhetri, iibhetri zeLithium-ion zahlukile ngobukhulu bazo obuncinci kunye neempawu ezikhaphukhaphu, nto leyo ezenza zilungele izixhobo ze-elektroniki eziphathwayo. Ukongeza, ziyakwazi ukugcina amandla amaninzi ombane, nto leyo ezenza zibe ngumthombo wamandla osebenzayo.
Indlela iibhetri ze-lithium-ion ezivelisa ngayo umbane
Umgaqo osisiseko wokusebenza kweebhetri uyafana, ubandakanya i-electrode echanekileyo (i-cathode), i-electrode engalunganga (i-electrode engalunganga), kunye ne-electrolyte. Ngaphakathi kwebhetri, i-electrolyte ivumela ii-ion ukuba zidlule, ngelixa ii-electron zihamba ukusuka kwi-electrode engalunganga ukuya kwi-electrode echanekileyo, ngaloo ndlela zivelisa umbane. Kwiibhetri zesibini, ezifana neebhetri ze-lithium-ion, zinokugcina ii-electron kwi-electrode engalunganga kwangaphambili ngokutshaja, kwaye xa ibhetri ikhutshiwe, ezi electron zihamba ziye kwi-electrode echanekileyo, ngaloo ndlela zivelisa umbane.
Okulandelayo, makhe sijonge iimpawu kunye neenzuzo zeebhetri ze-lithium-ion. Isizathu sokuba iibhetri ze-lithium-ion zivelele phakathi kweebhetri ezininzi kungenxa yesakhiwo sazo esahlukileyo kunye nokukhethwa kwezinto. Okokuqala, iibhetri ze-lithium-ion zisebenzisa iikhompawundi zesinyithi eziqulathe i-lithium kwi-electrode elungileyo kunye ne-carbon (ezifana ne-graphite) ezinokufunxa kwaye zigcine i-lithium kwi-electrode engalunganga. Olu yilo luvumela iibhetri ze-lithium-ion ukuba zivelise umbane ngaphandle kwesidingo sokubola ii-electrode ngokunyibilikisa i-electrolyte njengeebhetri zemveli, ngaloo ndlela kucothiswe ukuguga kwebhetri. Okwesibini, i-lithium yinto encinci nelula, eyenza iibhetri ze-lithium-ion zibe ncinci kwaye zibe lula ngomthamo ofanayo. Ukongeza, iibhetri ze-lithium-ion zikwanazo neengenelo zobuninzi bamandla aphezulu, ubomi obude bomjikelo, kunye nokungabikho kwesiphumo sememori, zonke ezi zenze iibhetri ze-lithium-ion zisetyenziswe kakhulu kwizixhobo ze-elektroniki eziphathwayo, izithuthi zombane kunye nezinye iindawo.
Uhlu lweebhetri ze-lithium
Iibhetri zeLithium-ion zahlulwe zibe ziindidi ezahlukeneyo ngokusekelwe kwizinto zesinyithi ezisetyenzisiweyo kwi-electrode elungileyo. Ekuqaleni, izinto zesinyithi ezisetyenzisiweyo kwi-electrode elungileyo yeebhetri zeLithium-ion yayiyiCobalt. Nangona kunjalo, imveliso yeCobalt iphantse ilingane neyeLithium, kwaye ikwayintsimbi engaqhelekanga, ngoko ke iindleko zokuvelisa ziphezulu. Ke ngoko, kwaqala ukusetyenziswa izinto ezingabizi kwaye zinobuhlobo nokusingqongileyo ezifana neManganese, Nickel, kunye neIron. Iibhetri zeLithium-ion zahlulwe ngokwezinto ezisetyenziswayo. Makhe sijonge iimpawu zodidi ngalunye.
| Iintlobo zeebhetri zeLithium-ion | I-Voltage | Amaxesha okukhupha | Okuhle nokubi |
| Iibhetri ze-lithium-ion ezisekwe kwiCobalt | 3.7V | Amaxesha angama-500 ～1000 |
|
| I-lithium-ion esekwe kwiManganese | 3.7V | Amaxesha angama-300 ～700 |
|
| Iibhetri ze-lithium-ion ezisekwe kwi-iron phosphate | 3.2V | Amaxesha ayi-1000 ～2000 |
|
| Iibhetri ze-lithium-ion ezisekwe kwi-ternary | 3.6V | Amaxesha ayi-1000 ～2000 |
