Umzi-mveliso webhetri ye-lead-asidi kwilizwe lam unembali engaphezu kwekhulu leminyaka. Ngenxa yeempawu zemathiriyeli exabiso liphantsi, itekhnoloji elula, itekhnoloji evuthiweyo, ukuzikhupha okuphantsi, kunye neemfuno zokungakhathali, iya kuhlala ilawula intengiso kumashumi ambalwa eminyaka azayo. Kwiinkalo ezininzi zesicelo, inkqubela yezobuchwepheshe yeebhetri ze-lead-acid yenze igalelo elibonakalayo ekuphuculeni ukukhuphisana kwelizwe. Ialloyi yeCalcium inamandla aphezulu e-hydrogen kunye nokumelana nomhlwa okuqinileyo. Isetyenziselwa ukwenza iigridi zebhetri ze-lead-asidi, ezinokuphucula ukusebenza kakuhle kwe-electrode engafanelekanga kwi-oksijini yangaphakathi yebhetri kunye nokwandisa ukusebenza kakuhle kwe-electrode efanelekileyo kwimijikelezo enzulu yokukhupha.
Ukusetyenziswa kweCalcium Aluminium Alloy kwiBattery yokuGcina
Iibhetri ze-lead-asidi zinembali ephantse ibe yi-160 iminyaka. Amandla alo obuninzi kunye nomthamo wamandla athile akanakuthelekiswa neNi-Cd, i-Ni-MH, i-Li ion kunye ne-Li polymer ibhetri. Kodwa ngenxa yexabiso layo eliphantsi, ukusebenza kakuhle kokukhupha okuphezulu kwangoku, kwaye akukho mpembelelo yememori, inokwenziwa ibe yibhetri enkulu yomthamo (4500Ah) kunye nokunye ukusebenza okuhle kakhulu. Ngoko ke, isasetyenziswa ngokubanzi kwiimoto, unxibelelwano, amandla ombane, i-UPS, umzila kaloliwe, umkhosi kunye namanye amasimi, kwaye ukuthengisa kwayo kusekho phambili kwiimveliso zamandla ekhemikhali.
Indlela i-calcium alloy ekhokela ngayo isetyenziswa ngokubanzi kwishishini lebhetri
1. Ukuze kuncitshiswe ukubola kwamanzi ebhetri kunye nokunciphisa umsebenzi wokulondoloza ibhetri, uHanring noThomas [50] baqulunqa i-alloy-calcium alloy ngo-1935, eyayisetyenziselwa ukuvelisa iigridi eziphosiweyo kwiibhetri ezimileyo ezisetyenziswa kumaziko onxibelelwano.
2. Isixhobo segridi esidla ngokusetyenziswa kwiibhetri ezingahlawulelwayo yi-Pb-Ca alloy. Ngokomxholo, ihlukaniswe ibe yi-calcium ephezulu, i-calcium ephakathi kunye ne-alloy ye-calcium ephantsi.
3. I-alloy-calcium alloy i-precipitation hardening, oko kukuthi, i-Pb3Ca yenziwe kwi-matrix ekhokelayo, kwaye i-intermetallic compound iyancipha kwi-matrix ekhokelayo ukwenza inethiwekhi enzima.
Igridi yeyona nto ibalulekileyo engasebenziyo kwiibhetri ze-lead-acid. Ukususela ekuqulunqweni kweebhetri ze-lead-acid, i-Pb-Sb i-alloy ibe yinto ebaluleke kakhulu kwiigridi. Ngokuvela kweebhetri ze-lead-asidi ezingenalo ukugcinwa, ii-alloys ze-Pb-Sb ziye zaba Ayinakukwazi ukuhlangabezana neemfuno zokusebenza zokugcinwa kweebhetri, kwaye ngokuthe ngcembe zitshintshwe ngamanye ama-alloys.
Uphononongo lufumene ukuba i-Pb-Ca alloy inomsebenzi ogqwesileyo wokungahoyi, kodwa i-intergranular corrosion phenomenon inzulu, kwaye umxholo we-calcium akulula ukuwulawula, ngakumbi ifilimu yokumelana ne-high-impedance eyenziwe kumphezulu wegridi yebhetri ithintela kakhulu. intlawulo yebhetri kunye nenkqubo yokukhupha. , Yenza i-battery's early capacity loss (PCL) isenzeko sibe sibi kakhulu, ngaloo ndlela sinciphisa kakhulu ubomi benkonzo yebhetri, apho impembelelo yegridi efanelekileyo kakhulu. Ukongeza inani elincinci le-aluminium kunempembelelo yokukhusela i-calcium. Uphando lufumanise ukuba i-tin ingaphucula ukusebenza kwefilimu ye-passivation kunye nokuphucula ukusebenza komjikelo onzulu webhetri.
