Ukuqonda kwangaphambili kweebhetri ze-lithium
Wamkelekile kwibhlog esemthethweni yeHeltec Energy! Iibhetri zeLithium-ion ziye zaba yinxalenye yobomi bethu bemihla ngemihla, izixhobo zombane esithembele kuzo, njengee-smartphones kunye neelaptops, kunye neemoto. Iprototype yebhetri yaqanjwa ngasekupheleni kwenkulungwane ye-18, kwaye sele ingaphezu kwamakhulu amabini eminyaka ukususela ngoko. Iibhetri zeLithium-ion yenye yezona ntlobo zintsha zeebhetri eziye zazalwa kwinkqubo yophuhliso lwebhetri.
Iibhetri zohlulwe zibe ziibhetri ezomileyo ezinokusetyenziswa kube kanye kuphela, "iibhetri zokuqala", kunye neebhetri ezinokutshajwa kwaye zisetyenziswe amaxesha amaninzi, "iibhetri zesekondari". Iibhetri zeLithium-ion ziibhetri zesibini ezinokutshajwa kwakhona. Xa kuthelekiswa nezinye iintlobo zeebhetri, iibhetri ze-lithium-ion zizodwa kubungakanani bazo obubambeneyo kunye neempawu ezikhaphukhaphu, ezizenza zilungele izixhobo zombane eziphathwayo. Ukongezelela, bayakwazi ukugcina ubuninzi bamandla ombane, okwenza kube ngumthombo wamandla osebenzayo.
Iibhetri ze-lithium-ion ziwenza njani umbane
Umgaqo osisiseko wokusebenza kweebhetri ufana, uquka i-electrode enhle (i-cathode), i-electrode engalunganga (i-electrode engalunganga), kunye ne-electrolyte. Ngaphakathi kwebhetri, i-electrolyte ivumela i-ion ukuba idlule, ngelixa ii-electron zihamba ukusuka kwi-electrode engafanelekanga ukuya kwi-electrode efanelekileyo, ngaloo ndlela ivelisa umsinga wombane. Kwiibhetri zesibini, ezifana neebhetri ze-lithium-ion, zinokugcina ii-electron kwi-electrode engalunganga kwangaphambili ngokutshaja, kwaye xa ibhetri ikhutshwe, ezi electron zihamba ziye kwi-electrode efanelekileyo, ngaloo ndlela zivelisa umbane.
Emva koko, makhe sijonge kwiimpawu kunye neenzuzo zeebhetri ze-lithium-ion. Isizathu sokuba iibhetri ze-lithium-ion zivelele phakathi kweebhetri ezininzi ngenxa yesakhiwo esikhethekileyo kunye nokukhethwa kwezinto eziphathekayo. Okokuqala, iibhetri ze-lithium-ion zisebenzisa i-lithium-containing metal compounds kwi-electrode efanelekileyo kunye nekhabhoni (njenge-graphite) ekwazi ukufunxa kunye nokugcina i-lithium kwi-electrode engafanelekanga. Olu luyilo luvumela iibhetri ze-lithium-ion ukuvelisa umbane ngaphandle kwesidingo sokubola i-electrode ngokunyibilikisa i-electrolyte njengeebhetri zendabuko, ngaloo ndlela inciphisa ukuguga kwebhetri. Okwesibini, i-lithium yinto encinci kwaye ilula, eyenza iibhetri ze-lithium-ion zidibanise ngakumbi kwaye zilula kumthamo ofanayo. Ukongeza, iibhetri ze-lithium-ion nazo zineenzuzo zokuxinana kwamandla aphezulu, ubomi bomjikelezo omude, kwaye akukho mphumo wokukhumbula, zonke ezo zenze iibhetri ze-lithium-ion zisetyenziswe ngokubanzi kwizixhobo zombane eziphathekayo, izithuthi zombane kunye nezinye iindawo.
Ukuhlelwa kweebhetri ze-lithium
Iibhetri ze-lithium-ion zihlelwa kwiindidi ezininzi ngokusekelwe kwizinto zetsimbi ezisetyenziswe kwi-electrode efanelekileyo. Ekuqaleni, izinto zetsimbi ezisetyenziswe kwi-electrode efanelekileyo yeebhetri ze-lithium-ion yayiyi-cobalt. Nangona kunjalo, imveliso ye-cobalt iphantse iphantsi njengaleyo ye-lithium, kwaye iyintsimbi enqabileyo, ngoko ke ixabiso lokuvelisa liphezulu. Ngoko ke, kwaqalisa ukusetyenziswa izixhobo ezingabizi mali ininzi nengenabungozi kokusingqongileyo njengemanganese, nickel, nentsimbi. Iibhetri zeLithium-ion zihlelwa ngokwezinto ezizisebenzisayo. Makhe sijonge iimpawu zodidi ngalunye.
| Iintlobo zeebhetri zeLithium-ion | I-Voltage | Amaxesha okukhutshwa | Okuhle nokubi |
| Iibhetri ze-lithium-ion ezisekelwe kwiCobalt | 3.7V | 500 ~ 1000 amaxesha |
|
| Manganese-based lithium-ion | 3.7V | 300 ~ 700 amaxesha |
|
| Iibhetri ze-iron phosphate-based lithium-ion | 3.2V | 1000 ~ 2000 amaxesha |
|
| Iibhetri ze-lithium-ion ezisekelwe kwi-ternary | 3.6V | 1000 ~ 2000 amaxesha |
