Intshayelelo:
Iibhetri ziyinxalenye ebalulekileyo yezixhobo ezininzi kunye neenkqubo, ukusuka kwii-smartphones kunye neelaptops ukuya kwiimoto kunye nokugcinwa kwelanga. Ukwazi uhlobo lwebhetri oyisebenzisayo kubalulekile kukhuseleko, ugcino kunye neenjongo zokuyilahla. Iintlobo ezimbini eziqhelekileyo zeebhetrii-lithium-ion (i-Li-ion)kunye neebhetri ze-lead-asidi. Uhlobo ngalunye luneempawu zalo kwaye lufuna ukuphathwa ngendlela eyahlukileyo. Kweli nqaku, siza kuxubusha indlela yokuxelela ukuba ibhetri yi-lithium okanye i-lead, kunye nokwahlukana okuphambili phakathi kwezi zimbini.
Imbonakalo
Enye yeendlela ezilula zokwahlula phakathi kweebhetri ze-lithium kunye ne-lead-asidi kukubonakala kwazo ngokwasemzimbeni. Iibhetri ze-lead-asidi zidla ngokuba nkulu kwaye zinzima kuneiibhetri ze-lithium-ion.Ngokuqhelekileyo zixande okanye isikweri ngokwemilo kwaye zinesiciko esiphuma ngaphandle esikhethekileyo ngaphezulu sokongeza amanzi. Xa kuthelekiswa, iibhetri ze-lithium-ion ziqhelekile ukuba zincinci, zikhaphukhaphu, kwaye ziza kwiimilo ezahlukeneyo, kubandakanywa icylindrical kunye neprismatic. Azinazigqubuthelo ezikhupha umoya kwaye zidla ngokuvalelwa kwisingxobo seplastiki.
Iithegi kunye neethegi
Enye indlela yokuchonga uhlobo lwebhetri kukukhangela iilebhile kunye nokuphawula kwibhetri ngokwayo. Iibhetri ze-lead-acid zihlala zineeleyibhile ezinje, kwaye zisenokuba neempawu ezibonisa amandla ombane kunye nomthamo. Ukongezelela, iibhetri ezineasidi yelothe zihlala zineelebhile ezilumkisayo malunga neengozi zeasidi yesulfuric kunye nemfuneko yokungena komoya ngendlela efanelekileyo. Iibhetri zeLithium-ion, kwelinye icala, zidla ngokubhalwa ngolwazi malunga nokwakheka kweekhemikhali, amandla ombane kunye nomthamo wamandla. Basenokuba neesimboli ezibonisa ukuthotyelwa kwemigangatho yokhuseleko, njenge-UL (Underwriters Laboratories) okanye iCE (European Conformity Assessment).
Umbane kunye nomthamo
Amandla ombane ebhetri kunye nomthamo nawo unokunika umkhondo malunga nohlobo lwayo. Iibhetri ze-lead-asidi ziqhele ukufumaneka kumbane we-2, 6, okanye i-12 volts kwaye ziqhele ukusetyenziswa kwiinkqubo ezifuna imveliso yangoku ephezulu, efana neebhetri zokuqalisa imoto. Iibhetri ze-lithium-ion, ngakolunye uhlangothi, zinamandla aphezulu, kunye ne-voltages ukusuka kwi-3.7 volts kwiseli enye ukuya kwi-48 volts okanye ngaphezulu kwiipakethi ezinkulu zebhetri ezisetyenziselwa izithuthi zombane okanye iinkqubo zokugcina amandla.
Iimfuno zesondlo
Ukuqonda iimfuno zokugcinwa kwebhetri kunokunceda ekuchongeni uhlobo lwayo. Iibhetri ze-lead-asidi zifuna ukugcinwa rhoqo, kubandakanywa ukujonga kunye nokuzalisa amanqanaba e-electrolyte ngamanzi adibeneyo, ukucoca iitheminali, kunye nokuqinisekisa ukungena komoya okufanelekileyo ukukhusela ukwakhiwa kwegesi ye-hydrogen eqhumayo. Okuchasene,iibhetri ze-lithium-ionazinakugcinwa kwaye azifuni ukunkcenkceshelwa rhoqo okanye ukucocwa kwetheminali. Nangona kunjalo, kufuneka zikhuselwe ekutshajisweni kunye nokukhutshwa okunzulu ukukhusela umonakalo kunye nokuqinisekisa ubomi obude.
Impembelelo kokusingqongileyo
Impembelelo yokusingqongileyo yebhetri inokuba yingqwalasela ephambili xa kumiselwa uhlobo lwebhetri. Iibhetri ezineasidi yelothe zineasidi yelothe kunye nesulfuric, zombini ezinokuba yingozi kwimekobume ukuba azilawulwa kakuhle. Ilothe yintsimbi enzima enetyhefu kwaye iasidi yesulphuric iyadla kwaye inokubangela ukungcoliseka komhlaba namanzi ukuba ayiphathwanga kakuhle kwaye ilahlwe. Iibhetri zeLithium-ion zikwabonisa imingeni yokusingqongileyo ngenxa yokukhutshwa kwe-lithium kunye nezinye izinyithi ezinqabileyo zomhlaba, ezinokuthi zikhokelele ekubalekeni kwe-thermal kunye nemililo ukuba ayiphinda isetyenziswe ngokufanelekileyo. Ukuqonda impembelelo yokusingqongileyo yeebhetri kunokukunceda wenze izigqibo ezizizo malunga nokusetyenziswa kwebhetri kunye nokulahla.
Ukulahlwa kunye nokuhlaziywa kwakhona
Ukulahlwa ngendlela eyiyo kunye nokurisayikilisha kweebhetri kubalulekile ekucutheni impembelelo yokusingqongileyo kunye nokuqinisekisa ukuba izinto ezixabisekileyo ziyafunyanwa. Iibhetri ezineasidi yelothe zidla ngokuphinda zisetyenziswe ukuze kuphinde kusetyenziswe ilothe neplastiki, ezinokuthi zisetyenziswe ukwenza iibhetri ezintsha nezinye iimveliso. Ukurisayikilisha iibhetri ze-lead-asidi kunceda ukuthintela ukosuleleka kwelothe kunye nokugcina imithombo yendalo.Iibhetri zeLithium-ionnazo ziqulethe izinto ezixabisekileyo ezifana ne-lithium, i-cobalt kunye ne-nickel, enokuthi ihlaziywe kwaye isetyenziswe kwakhona kwiibhetri ezintsha. Nangona kunjalo, isiseko sokuhlaziya iibhetri ze-lithium-ion sisaphuhliswa, kwaye iinkqubo ezifanelekileyo zokuphinda zisetyenziswe zibalulekile ekunciphiseni ingozi yendalo.
Iingqwalasela zokhuseleko
Ukhuseleko luyinto ephambili xa uphatha kwaye uchonga iibhetri, ngakumbi iibhetri ze-lithium-ion, ezaziwa ngokuba zihamba nge-thermal runaway kwaye zibambe umlilo xa zonakaliswe okanye zihlawuliswe ngokungafanelekanga. Ukuqonda izilumkiso zokhuseleko kuhlobo ngalunye lwebhetri kubalulekile ukuthintela iingozi kunye nokuqinisekisa ukuphathwa ngendlela eyiyo. Iibhetri ezineasidi yelothe zinokukhupha irhasi yehydrogen eqhumayo ukuba itshajiswe kakhulu okanye imfutshane, kwaye inokubangela ukutsha kweekhemikhali ukuba i-electrolyte idibana nolusu okanye amehlo. Amanyathelo okhuseleko afanelekileyo, afana nokusebenzisa izixhobo zokhuselo lomntu kunye nokulandela izikhokelo zomenzi, abalulekile xa usebenza nalo naluphi na uhlobo lwebhetri.
Ukuqukumbela
Isishwankathelo, ukuchonga ukuba ibhetri i-lithium okanye i-lead-asidi idinga ukuqwalaselwa kwezinto ezahlukeneyo, kubandakanywa ukubonakala komzimba, iilebhile kunye nokumakisha, i-voltage kunye nomthamo, iimfuno zokugcina, impembelelo yokusingqongileyo, ukhetho lokulahla kunye nokuhlaziywa kwakhona, kunye nokuqwalaselwa kokhuseleko. Ngokuqonda umahluko phakathi kwebhetri ye-lithium-ion kunye ne-lead-acid, abantu kunye nemibutho banokwenza izigqibo ezinolwazi malunga nokusetyenziswa kwabo, ukugcinwa kunye nokulahla. Ukuchongwa ngokufanelekileyo kunye nokuphathwa kweebhetri kubalulekile kukhuseleko, ukhuseleko lokusingqongileyo kunye nokugcinwa kwemithombo. Ukuba uyathandabuza malunga nohlobo lwebhetri, kuyacetyiswa ukuba udibane nomenzi okanye uchwepheshe oqeqeshiweyo ukuze ufumane isikhokelo.
