Uyini umehluko phakathi kwamabhethri e-lithium namabhethri omile? Kungani amabhethri eselula engawasebenzisi amabhethri omile?

Liyini ibhethri elomile, ibhethri ye-lithium, futhi kungani omakhalekhukhwini basebenzisa amabhethri e-lithium esikhundleni samabhethri omile?

1. Ibhethri eyomile

Amabhethri omile nawo asephenduke amabhethri e-voltaic. Amabhethri e-Voltaic akhiwa amaqembu amaningi amapuleti ayindilinga avela ngamabili futhi apakishwe ngendlela ethile. Kunamapuleti ensimbi amabili ahlukene epuleti eliyindilinga, futhi kukhona ungqimba lwendwangu phakathi kwamazinga okuhambisa ugesi. Umsebenzi, ibhethri elomile lenziwa ngokwalesi simiso. Kukhona into efana ne-paste ngaphakathi kodaka olomile, okunye okuyi-gelatin. Ngakho-ke, i-electrolyte yayo ifana nokunamathisela, futhi Ayikwazi ukushajwa kabusha ibhethri elilahlwayo lalolu hlobo lwebhethri ngemva kokulahlwa. Amandla e-electromotive of the zinc-manganese dry mortar ngu-1.5V, futhi okungenani amabhethri omile amaningi ayadingeka ukushaja iselula.

Esivame ukukubona amabhethri angu-5 kanye no-7. Amabhethri No. 1 kanye No. 2 asetshenziswa kancane uma kuqhathaniswa. Leli bhethri lisetshenziswa kakhulu kumagundane angenantambo, amawashi ama-alamu, amathoyizi kagesi, amakhompyutha, namarediyo. Ibhethri le-Nanfu alikwazanga ukujwayeleka kakhulu; yinkampani yebhethri edumile eFujian.

2. Ibhetri ye-lithiamu

Isixazululo sangaphakathi sebhethri ye-lithium yisisombululo esingenamanzi se-electrolyte, futhi izinto eziyingozi ze-electrode zenziwe nge-lithium metal noma i-lithium alloy. Ngakho-ke, umehluko phakathi kwebhethri nebhethri elomile ukuthi izinto zokusabela zangaphakathi zebhethri zihlukile, nezici zokushaja ezinye. Ingakwazi ukushaja kabusha ibhethri ye-lithium. Amabhethri e-lithium ngokuvamile anezinhlobo ezimbili: amabhethri ensimbi e-lithium namabhethri e-lithium-ion. Lawa mabhethri asetshenziswa kakhulu kumaselula, ezimotweni zikagesi, ezinsikeni ezincane zasendlini, omakhalekhukhwini, izincwadi zokubhalela, zokugunda ugesi, njll., futhi asetshenziswa kakhulu kunamabhethri omile.

Amabhethri ahlukaniswa abe aphinde ashajwe (abuye abizwe ngokuthi amabhethri amanzi) nangaphinde ashajwe (abuye abizwe ngokuthi amabhethri omile).

Phakathi kwamabhethri angaphinde ashajwe, amabhethri e-AA yiwona ayinhloko, abizwa ngokuthi amabhethri e-alkaline.

Amabhethri e-lithium-ion angcono. Ukubekezela cishe kuphindwe kahlanu kunamabhethri e-alkaline, kodwa inani liphindwe kahlanu.

Njengamanje, amabhethri e-lithium-ion No. 5 e-Panasonic ne-Rimula angamabhethri angcono kakhulu angashajwa. Amabhethri aphinde ashajwe ahlukaniswe abe amabhethri e-nickel-cadmium, nickel-hydrogen, namabhethri e-lithium-ion aphinde ashajwe.

Phakathi kwazo, amabhethri e-lithium-ion aphinde ashajwa angcono kakhulu. Amabhethri e-nickel-cadmium ngokuvamile awusayizi wamabhethri we-AA, amadala futhi aphelile, kodwa asathengiswa ngaphandle.

Amabhethri e-Ni-MH ngokuvamile angusayizi weNombolo 5 futhi manje asengamabhethri ajwayelekile No. 5 aphinde ashajwe, angu-2300mAh kuya ku-2700mAh njengawo ajwayelekile. Amabhethri aphinde ashajwe yi-lithium-ion ngokuvamile awusayizi odizayinwe umenzi. Ngokuqondene nokukhuthazela kwamabhethri aphinde ashajwe, amabhethri e-lithium-ion aphinde ashajwa angcono kakhulu, alandelwe yi-nickel-metal hydride bese kuba yi-nickel-cadmium.

I-Lithium-ion ingagcina amandla angaphezu kuka-90%, kuze kube okokugcina cishe ku-5% wamandla, bese iphela kungazelelwe. Ibhethri ye-nickel-hydrogen ihamba yonke indlela, okubonisa ukuthi bekuyi-90% ekuqaleni, bese kuba ngu-80%, bese kuba ngu-70%.

Impilo yebhethri yalolu hlobo lwebhethri ayikwazi ukwanelisa imikhiqizo ye-elekthronikhi edla amandla amaningi, ikakhulukazi uma ikhamera yedijithali idinga ukukhanya, kuthatha isikhathi eside ukuthatha esinye isithombe, futhi ibhethri elishajekayo le-lithium-ion alinayo. le nkinga. Ngakho-ke uma ikhamera ingelona ibhethri le-AA, kuzoba ibhethri elishajekayo le-lithium-ion eliklanywe umenzi.

Lokhu ukukhetha kokuqala. Uma kuyibhethri le-AA, ungazithengela ibhethri elishajekayo le-nickel-metal hydride futhi uthenge ishaja engcono. Kungcono ukukhipha bese ushaja kuqala, okuzokwelula impilo yesiphepho.

Izici zokuqhathanisa zebhethri ye-lithium nebhethri elomile:

1. Amabhethri omile amabhethri alahlwayo, futhi amabhethri e-lithium amabhethri aphinde ashajwe, angashajwa kaningi futhi angabi nayo inkumbulo. Ayidingi ukushajwa ngokwenani likagesi futhi ingasetshenziswa njengoba kudingeka;
2. Amabhethri omile angcoliswe kakhulu. Amabhethri amaningi ayequkethe izinsimbi ezisindayo njengemercury nomthofu esikhathini esidlule, okwakubangela ukungcoliswa okukhulu kwemvelo. Ngenxa yokuthi amabhethri alahlwayo, alahlwa ngokushesha lapho esephelile, kodwa amabhethri e-lithium awaqukethe izinsimbi eziyingozi;
3. Amabhethri e-lithium nawo anomsebenzi wokushaja okusheshayo, futhi impilo yomjikelezo nayo iphakeme kakhulu, okungaphezu kwamandla amabhethri omile. Amabhethri amaningi e-lithium manje anamasekhethi okuvikela ngaphakathi.
