Imboni yebhethri ene-asidi eholayo ezweni lami inomlando ongaphezu kweminyaka eyikhulu. Ngenxa yezici zezinto ezishibhile, ubuchwepheshe obulula, ubuchwepheshe obuvuthiwe, ukuzikhipha okuphansi, kanye nezidingo ezinganakekelwa, kusazobusa imakethe emashumini ambalwa eminyaka azayo. Ezinkambini eziningi zohlelo lokusebenza, inqubekelaphambili yobuchwepheshe yamabhethri e-lead-acid yenze umnikelo obonakalayo ekuthuthukiseni ukuncintisana kazwelonke. I-calcium alloy inamandla aphezulu e-hydrogen kanye nokumelana nokugqwala okuqinile. Isetshenziselwa ukwenza amagridi ebhethri ane-asidi eholayo, engathuthukisa ukusebenza kahle kwe-electrode eyinegethivu kumoya-mpilo wangaphakathi webhethri futhi ikhulise ukusebenza kahle kwe-electrode ephozithivu emijikelezweni yokuphuma ejulile.
Ukusetshenziswa kwe-Calcium Aluminium Alloy kubhethri yesitoreji
Amabhethri e-lead-acid anomlando cishe weminyaka eyi-160. Amandla ayo akhethekile kanye namandla athile evolumu awanakuqhathaniswa namabhethri e-Ni-Cd, i-Ni-MH, i-Li ion ne-Li polymer. Kodwa ngenxa yenani layo eliphansi, ukusebenza kahle kokukhishwa okuphezulu kwamanje, futhi akukho mphumela wenkumbulo, ingenziwa ibe ibhethri elilodwa elikhulu (4500Ah) nokunye ukusebenza okuhle kakhulu. Ngakho-ke, isasetshenziswa kakhulu kwezezimoto, ezokuxhumana, emandleni kagesi, e-UPS, esitimela, ezempi nakweminye imikhakha, futhi ukuthengiswa kwayo kusahamba phambili emikhiqizweni yamandla amakhemikhali.
Indlela i-calcium alloy ehola ngayo isetshenziswa kabanzi embonini yebhethri
1. Ukuze kuncishiswe ukubola kwamanzi ebhethri futhi kuncishiswe umsebenzi wokunakekela ibhethri, u-Hanring noThomas [50] basungula ingxubevange ye-lead-calcium ngo-1935, eyasetshenziselwa ukukhiqiza amagridi asakazwa amabhethri anganyakazi asetshenziswa ezikhungweni zokuxhumana.
2. Into yegridi evame ukusetshenziswa kumabhethri anganakekeli i-Pb-Ca alloy. Ngokusho kokuqukethwe, ihlukaniswe nge-calcium ephezulu, i-calcium ephakathi kanye ne-calcium alloy ephansi.
3. I-lead-calcium alloy iwukuqina kwezulu, okungukuthi, i-Pb3Ca yakheka ku-matrix yokuhola, futhi inhlanganisela ye-intermetallic idlula ku-matrix yokuhola ukuze yakhe inethiwekhi eqinile.
Igridi iyinto ebaluleke kakhulu engasebenzi kumabhethri e-lead-acid. Kusukela kwasungulwa amabhethri e-lead-acid, i-Pb-Sb alloy ibe yinto ebaluleke kakhulu kumagridi. Ngokuvela kwamabhethri e-asidi eholayo angalondolozi, ama-alloy e-Pb-Sb asengakwazi ukuhlangabezana nezidingo zokusebenza okungalondoloziwe kwamabhethri, futhi kancane kancane athathelwa indawo amanye ama-alloy.
Ucwaningo luthole ukuthi i-Pb-Ca alloy inokusebenza okuhle kakhulu kokungalungiseki, kodwa isimo sayo sokugqwala kwe-intergranular sibucayi, futhi okuqukethwe kwe-calcium akulula ukukulawula, ikakhulukazi ifilimu ye-high-impedance passivation eyakhiwe phezu kwegridi yebhethri ivimbela kakhulu. ukushajwa kwebhethri nenqubo yokukhipha. , Yenza ukwenzeka kokulahlekelwa kwamandla okuqala kwebhethri (PCL) kube kubi kakhulu, ngaleyo ndlela ufinyeze kakhulu impilo yesevisi yebhethri, okunomthelela wegridi enhle kakhulu. Ukwengeza inani elincane le-aluminium kunomphumela wokuvikela i-calcium. Ucwaningo luthole ukuthi i-tin ingathuthukisa ukusebenza kwefilimu ye-passivation futhi ithuthukise ukusebenza komjikelezo ojulile webhethri.
