Zeziphi iintlobo zeebhetri ze-lithium ezilungiselelweyo?
Ngokwezixhobo ezahlukeneyo ze-electrolyte ezisetyenziswa kwiibhetri ze-lithium ezilungiselelweyo, zohlulwe ikakhulu kwiibhetri ze-lithium ion kunye neebhetri ze-lithium ion ze-polymer.
Iibhetri ze-lithium ezitshajwayo ngoku zisetyenziswa ngokubanzi kwiimveliso zedijithali zanamhlanje ezifana neeselfowuni kunye neekhompyuter zeencwadana. Ingaba ibhetri ye-lithium ye-18650 okanye ibhetri ye-iron-lithium, akufanele ihlawulwe ngexesha lokusetyenziswa, ngaphandle koko ibhetri iya konakaliswa okanye ichithwe. Kukho isiphaluka sokukhusela kwibhetri ukukhusela umonakalo obiza kakhulu. Iimfuno zokutshaja ibhetri yeLithium-ion ziphezulu kakhulu. Ukuqinisekisa ukuba i-voltage yokuphelisa ingaphakathi okanye ikhupha ipesenti enye, abavelisi abakhulu bezixhobo ze-semiconductor baye baphuhlisa iindidi ze-lithium-ion zokutshaja ii-ICs ukuqinisekisa ukutshaja okuzinzile, okuthembekileyo, kunye nokukhawuleza.
Iifowuni eziphathwayo zisebenzisa iibhetri ze-lithium ezilungiselelweyo. Ukusetyenziswa okuchanekileyo kweebhetri ze-lithium kubaluleke kakhulu ukwandisa ubomi bebhetri. Ingenziwa kwiimilo ezahlukeneyo ngokweemfuno zeembono ezahlukeneyo kunye neemveliso, kwaye ibhetri eyenziwe ngeebhetri ezininzi kuthotho kunye nokuhambelana. Iqela. I-voltage elinganisiweyo yebhetri ye-lithium ngokuqhelekileyo yi-3.7V ngenxa yokutshintsha kwezinto, kunye ne-electrode efanelekileyo yebhetri ye-lithium iron phosphate yi-3.2V. Umbane wokugqibela wokutshaja xa ugcwaliswe ngokupheleleyo ngokuqhelekileyo yi-4.2V. I-voltage yokugqibela yokukhutshwa kwebhetri ye-lithium yi-2.75V-3.0V. Ukuba iyaqhubeka nokukhupha ngaphantsi kwe-2.5V, iya kuba yi-overdischarge, kwaye i-overdischarge iya konakalisa ibhetri.
