Ukuqhathaniswa kwamabhethri e-Lithium-Ion namabhethri e-Lead Acid
Amabhethri ayisici esibalulekile kumadivayisi amaningi esimanje, kusukela kumafoni aphathwayo nama-laptop kuya ezimotweni zikagesi, kuya ezinhlelweni zokugcina amandla emakhaya nasezimbonini. Phakathi kwezinhlobo eziningi zamabhethri atholakalayo, amabhethri e-lithium-ion (Li-ion) kanye ne-lead-acid yiwona amabili aqhathaniswa kakhulu. Womabili anezici zawo, izinzuzo, kanye nemikhawulo yawo. Lesi sihloko sixoxa ngomehluko obalulekile phakathi kwalawa amabili mayelana nendlela asebenza ngayo, ukusebenza kwawo, izindleko, ukuphepha, kanye nomthelela wawo emvelweni.
1. Ukubuka Konke kanye Nokuthi Kusebenza Kanjani
Amabhethri e-lead-acid awubuchwepheshe obudala, obusetshenziswa kusukela ngekhulu le-19. Lawa mabhethri asebenzisa ama-electrode enziwe nge-lead (Pb) kanye ne-lead dioxide (PbO₂), ane-electrolyte ye-sulfuric acid (H₂SO₄). Lapho ibhethri liqhuba ugesi, ukusabela kwamakhemikhali kuguqula izinto ze-electrode zibe yi-lead sulfate bese kudla i-electrolyte. Uma ishajwa kabusha, lokhu kusabela kuyaguqulwa.
Okwamanje, amabhethri e-lithium-ion awubuchwepheshe besimanje futhi avame ukutholakala kumadivayisi kagesi nasezimotweni zikagesi. Amabhethri e-Li-ion asebenza ngokudlulisa ama-ion e-lithium phakathi kwe-anode ne-cathode nge-electrolyte. Uma esetshenziswa, ama-ion asuka ku-anode aye ku-cathode, akhiqize ukugeleza kwama-electron ngesekethe yangaphandle. Uma eshajwa, inqubo iyaguqulwa. Kunezinhlobo eziningana zamakhemikhali e-Li-ion (njenge-NMC, i-LFP, i-NCA), kodwa isimiso esiyisisekelo siyafana.
2. Ubuningi Bamandla Nobukhulu
Omunye wemehluko ogqamile kakhulu ubuningi bamandla—ukuthi angakanani amandla angagcinwa ngekhilogramu noma ilitha.
