Izinselelo ze-NiMH noma amabhethri e-lithium aphinde ashajwa
Umphumela wenkumbulo we-NiMH nokuzikhulula
Amabhethri e-NiMH abhekana nezinselele ezihlobene neumphumela wenkumbulonokuzikhulula. Umthelela wenkumbulo uvela lapho amabhethri eshajwa ngokuphindaphindiwe ngaphambi kokuba akhishwe ngokuphelele. Lokhu kushintsha ukwakheka kwekristalu ngaphakathi kwebhethri, okwandisa ukumelana kwangaphakathi nokunciphisa umthamo ngokuhamba kwesikhathi. Yize kubi kakhulu kunakumabhethri e-nickel-cadmium (NiCd), umthelela wenkumbulo usathinta ukusebenza kwe-NiMH.
Ukuzikhulula kungenye inkinga. Amaseli aguga athuthukisa amakristalu amakhulu kanye nokukhula kwe-dendritic, okwandisa i-impedance yangaphakathi. Lokhu kuholela emazingeni aphezulu okuzikhipha, ikakhulukazi lapho ama-electrode okuvuvukala ecindezela i-electrolyte nesihlukanisi.
| Uhlobo lobufakazi | Incazelo |
|---|---|
| Umphumela Wenkumbulo | Amashaji angajulile aphindaphindiwe ashintsha isakhiwo sekristalu, ehlisa umthamo. |
| Ukuzikhipha | Amaseli aguga kanye nama-electrode okuvuvukala akhuphula izinga lokuzikhulula. |
Lezi zinselele zenza amabhethri e-NiMH angafaneleki kakhulu ezinhlelweni ezidinga ukugcinwa isikhathi eside noma ukusebenza okuphezulu okungaguquki. Ukunakekela kahle, njengokushajwa ngokugcwele kwebhethri ngezikhathi ezithile, kunganciphisa le miphumela.
Ukukhathazeka ngokuphepha kwebhethri ye-Lithium
Amabhethri e-lithium, ngenkathi isebenza kahle, ibeka izingozi ezinkulu zokuphepha. Ukubaleka okushisayo, okubangelwa ukushisa ngokweqile noma amasekhethi amafushane, kungaholela emlilweni noma ukuqhuma. Izinhlayiya zensimbi ezincanyana ngaphakathi kwebhethri zingase zicuphe amasekhethi amafushane, zikhulise ubungozi. Abakhiqizi basebenzise imiklamo elandelanayo yokubhekana nalezi zinkinga, kodwa izigameko zisenzeka.
Ukukhunjulwa kwamaphekhi e-lithium-ion acishe abe yizigidi eziyisithupha asetshenziswa kumakhompyutha aphathekayo agqamisa ubungozi. Ngisho nangezinga lokuhluleka kokukodwa kwezi-200,000, amandla okulimala asalokhu emakhulu. Ukwehluleka okuhlobene nokushisa kuphathelene ikakhulukazi, ikakhulukazi emikhiqizweni yabathengi nasezimotweni zikagesi.
| Isigaba | Ingqikithi Yokulimala | Ingqikithi Yokufa |
|---|---|---|
| Imikhiqizo Yabathengi | 2,178 | 199 |
| Izimoto zikagesi (>20MPH) | 192 | 103 |
| Amadivayisi e-Micro-Mobility (<20MPH) | 1,982 | 340 |
| Amandla Storage Systems | 65 | 4 |
Lezi zibalo zigcizelela ukubaluleka kokuthobela izimiso zokuphepha uma usebenzisa amabhethri e-lithium.
