1,Isisindo

Ngokwamandla kagesi weseli ngalinye, i-NiMH ne-NiCd ingu-1.2V, kuyilapho amabhethri e-Li-ion eyi-3.6V ngempela, kanti amandla kagesi e-Li-ion aphindwe kathathu kunawamanye amabili. Futhi isisindo sohlobo olufanayo lwamabhethri e-lithium-ion namabhethri e-nickel-cadmium acishe alingane, kuyilapho amabhethri e-nickel-metal hydride e-nickel enzima kakhulu. Kungabonakala ukuthi isisindo sebhethri ngalinye ngokwalo sihlukile, kodwa amabhethri e-lithium-ion ngenxa ye-voltage ephezulu ye-3.6V, inani lenhlanganisela yebhethri ngayinye esimweni sokuphuma kwe-voltage efanayo lingancishiswa ngengxenye eyodwa kwezintathu futhi isisindo kanye nevolumu yebhethri elakhiwe kuncishisiwe.

2.umphumela wenkumbulo

Amabhethri e-NiMH anomphumela wenkumbulo ofanayo namabhethri e-NiCd. Ngakho-ke, ukuphathwa kokukhishwa okuvamile kuyadingeka. Lokhu kulawulwa kokukhishwa okuvamile kuphathwa esimweni esingacacile, futhi ngisho nokunye kukhishwa ngaphansi kolwazi olungalungile (ukukhishwa ngakunye noma ukukhishwa ngemva kokusetshenziswa okuningana kuyahlukahluka kusuka enkampanini kuya enkampanini) Lokhu kulawulwa kokukhishwa okuyisicefe akukwazi ukuvinjelwa uma usebenzisa amabhethri e-NiMH. Ngokuphambene, amabhethri e-lithium-ion alula kakhulu futhi kulula ukuwasebenzisa ngoba awanawo nhlobo umthelela wenkumbulo. Akudingekile ukunaka i-voltage esele ukuthi singakanani, isikhathi sokushajwa kabusha, sokushaja ngokwemvelo singafinyezwa.

3.izinga lokuzikhipha

Ibhethri le-NiCd lingu-15-30% (inyanga) Ibhethri le-NiMH lingu-25 ~ 35% (inyanga), ibhethri ye-lithium-ion ngu-2 ~ 5% (inyanga). Izinga lokuzikhulula lebhethri le-NiMH elingenhla likhulu kakhulu, kuyilapho okukhethekile kwebhethri ye-lithium-ion kunezinga lokukhipha eliphansi kakhulu uma kuqhathaniswa nezinye izinhlobo ezimbili zamabhethri.

4.indlela yokushaja

Amabhethri e-NiMH namabhethri e-lithium-ion awakwazi ukumelana nokushajwa ngokweqile. Ngakho-ke, amabhethri e-NiMH anemodi yokulawula yokushaja yamanje ye-PICKCUT ku-voltage yokushaja afinyelela ezingeni eliphezulu, yeka ukuqhubeka nokushaja njengendlela engcono kakhulu yokushaja. Amabhethri e-lithium-ion ashajwa kahle kakhulu ngamanje kanye ne-voltage, futhi amabhethri e-NiMH ne-Li-ion ashajwa kangcono ngendlela yokulawula ishaja-DV yamabhethri e-NiCd.

i-prismatic vs pouch cell, ibhethri yekhibhodi engenantambo, ibhethri ye-ebike 48v, ishaja yebhethri yesipika se-bluetooth, inani lebhethri le-oximeter, ibhethri le-drone mavic mini, ibhethri ye-lithium ion engu-21700.
