1, Ubunzima

Ngokwe-voltage yeseli nganye, i-NiMH kunye ne-NiCd yi-1.2V, ngelixa iibhetri ze-Li-ion ziyi-3.6V ngokwenene, kwaye i-voltage yeebhetri ze-Li-ion iphindwe kathathu kunezinye ezimbini. Kwaye ubunzima bohlobo olufanayo lweebhetri ze-lithium-ion kunye neebhetri ze-nickel-cadmium ziphantse zilingane, ngelixa iibhetri ze-nickel-metal hydride zinzima. Inokubonwa ukuba ubunzima bebhetri nganye ngokwalo buhluke, kodwa iibhetri ze-lithium-ion ngenxa yombane ophezulu we-3.6V, inani leendibaniselwano zebhetri nganye kwimeko yokuphuma kwamandla ombane omnye kunokuncitshiswa ngesinye kwisithathu kwaye ubunzima kunye nomthamo webhetri eyenziweyo iyancipha.

2.impembelelo yenkumbulo

Iibhetri zeNiMH zineempembelelo zenkumbulo ezifanayo njengeebhetri zeNiCd. Ngoko ke, ulawulo lokukhutshwa rhoqo luyimfuneko. Olu lawulo lokukhutshwa rhoqo luphathwa kwimeko engacacanga, kwaye ezinye zikhutshwe phantsi kolwazi olungachanekanga (ukukhutshwa okanye ukukhutshwa ngalunye emva kokusetyenziswa okuningana kuyahluka ukusuka kwinkampani ukuya kwinkampani) Olu lawulo oludinayo lokukhutshwa alunakuthintelwa xa usebenzisa iibhetri ze-NiMH. Ngokwahlukileyo, iibhetri ze-lithium-ion zilula kakhulu kwaye kulula ukuzisebenzisa ngenxa yokuba azinampembelelo yememori kwaphela. Akunyanzelekanga ukuba ithathele ingqalelo i-voltage eshiyekileyo ukuba yimalini, ukutshajwa ngokuthe ngqo, ixesha lokutshaja linokunqunyulwa ngokwendalo.

3.izinga lokuzikhupha

Ibhetri ye-NiCd yi-15-30% (inyanga) ibhetri ye-NiMH yi-25 ~ 35% (inyanga), ibhetri ye-lithium-ion yi-2 ~ 5% (inyanga). Izinga lokuzikhupha kwibhetri ye-NiMH engentla iyona inkulu, ngelixa i-specialty ye-lithium-ion ibhetri inezinga eliphantsi kakhulu lokukhupha xa kuthelekiswa nezinye iintlobo ezimbini zeebhetri.

4.indlela yokutshaja

Iibhetri ze-NiMH kunye neebhetri ze-lithium-ion azikwazi ukumelana nokutshaja. Ke ngoko, iibhetri ze-NiMH ezinemowudi yolawulo ye-PICKCUT yokutshaja rhoqo kwi-voltage yokutshaja ifikelela kwinqanaba eliphezulu, yeka ukuqhubeka nokutshaja njengeyona ndlela ibalaseleyo yokutshaja. Iibhetri ze-lithium-ion zihlawuliswa kakuhle ngokuqhubekayo kunye ne-voltage, kwaye iibhetri ze-NiMH kunye ne-Li-ion zihlawuliswa kakuhle ngendlela yokulawula ishaja-DV yeebhetri ze-NiCd.

I-prismatic vs pouch cell, utshintsho lwebhetri engenazingcingo, ibhetri ye-ebike 48v, ibhetri ye-bluetooth yesithethi sebluetooth, ixabiso lebhetri ye-oximeter, ibhetri ye-drone mavic mini, ibhetri ye-21700 lithium ion.
