Uthini umahluko phakathi kweebhetri ze-lithium kunye neebhetri ezomileyo? Kutheni iibhetri zefowuni ephathwayo zingasebenzisi iibhetri ezomileyo?

Yintoni ibhetri eyomileyo, ibhetri ye-lithium, kwaye kutheni iifowuni eziphathwayo zisebenzisa iibhetri ze-lithium endaweni yeebhetri ezomileyo?

1. Ibhetri eyomileyo

Iibhetri ezomileyo ziye zaba ziibhetri zevoltaic. Iibhetri zeVoltaic zenziwe ngamaqela amaninzi eepleyiti zesetyhula ezibonakala ngambini kwaye zipakishwe ngendlela ethile. Kukho iipleyiti zetsimbi ezimbini ezahlukeneyo kwipleyiti esetyhula, kwaye kukho umaleko welaphu phakathi kwamanqanaba okuqhuba umbane. Umsebenzi, ibhetri eyomileyo yenziwa ngokwalo mgaqo. Kukho into efana nentlama ngaphakathi kodaka olomileyo, ezinye zazo ziyi-gelatin. Ke ngoko, i-electrolyte yayo ifana nokuncamathelisa, kwaye ayinakuphinda itshaje ibhetri elahlayo yolu hlobo lwebhetri emva kokuba ikhutshiwe. I-electromotive force ye-zinc-manganese dry mortar yi-1.5V, kwaye ubuncinane iibhetri ezomileyo ezininzi ziyafuneka ukuba zitshaje ifowuni ephathwayo.

Into esihlala siyibona yiNombolo yesi-5 kunye neNombolo ye-7 yeebhetri. I-Nombolo ye-1 kunye neNombolo ye-2 iibhetri zisetyenziswa kancinci. Le bhetri isetyenziswa kakhulu kwiimpuku ezingenazingcingo, iiwotshi ze-alam, iithoyi zombane, iikhomputha kunye nonomathotholo. Ibhetri yeNanfu ayinakuqheleka ngakumbi; yinkampani edumileyo yebhetri eFujian.

2. Ibhetri yeLithium

Isisombululo sangaphakathi sebhetri ye-lithium sisisombululo esingenamanzi se-electrolyte, kunye nezinto ezinobungozi ze-electrode zenziwe nge-lithium metal okanye i-lithium alloy. Ngoko ke, umahluko phakathi kwebhetri kunye nebhetri eyomileyo kukuba izinto zokuphendula zangaphakathi zebhetri zihlukile, kwaye iimpawu zokutshaja zizinye. Iyakwazi ukutshaja ibhetri ye-lithium. Iibhetri zeLithium ngokubanzi zineentlobo ezimbini: iibhetri zetsimbi ze-lithium kunye neebhetri ze-lithium-ion. Ezi bhetri zisetyenziswa ngokubanzi kwiifowuni eziphathwayo, izithuthi zombane, izixhobo ezincinci zendlu, iifowuni eziphathwayo, iincwadana, ii-shavers zombane, njl., kwaye zisetyenziswa kakhulu kuneebhetri ezomileyo.

Iibhetri zohlulwe zibe zibhetri ezikwaziyo ukutshajwa (ezikwabizwa ngokuba ziibhetri ezimanzi) nezingaphinde zitshajwe (ezikwabizwa ngokuba ziibhetri ezomileyo).

Phakathi kweebhetri ezingahlawulekiyo, iibhetri ze-AA zezona ziphambili, ezibizwa ngokuba ziibhetri ze-alkaline.

Iibhetri zeLithium-ion zezona zingcono. Ukunyamezela kumalunga namaxesha amahlanu eebhetri zealkaline, kodwa ixabiso liphindwe kahlanu.

Okwangoku, i-Panasonic kunye ne-Rimula ye-lithium-ion No. Iibhetri ezinokutshajwa kwakhona zahlulwe zibe yi-nickel-cadmium, i-nickel-hydrogen, kunye neebhetri ze-lithium-ion ezinokutshajwa kwakhona.

Phakathi kwazo, iibhetri ze-lithium-ion rechargeable zezona zilungileyo. Iibhetri ze-nickel-cadmium zihlala zilingana neebhetri ze-AA, ezindala kwaye zisusiwe, kodwa zisathengiswa ngaphandle.

Iibhetri ze-Ni-MH zivame ubungakanani beNombolo ye-5 kwaye ngoku ziyi-Nombolo ye-5 yeebhetri ezihlaziyiweyo, kunye ne-2300mAh ukuya kwi-2700mAh njengeyona nto iphambili. Iibhetri zeLithium-ion ezitshajwayo zidla ngokulingana nomenzi. Ngokuphathelele ukunyamezela kweebhetri ezinokutshajwa kwakhona, iibhetri ze-lithium-ion ezitshajwayo zezona zilungileyo, zilandelwa yi-nickel-metal hydride kunye ne-nickel-cadmium.

I-Lithium-ion inokugcina amandla ngaphezu kwe-90%, kude kube yinto yokugqibela ephantse ibe yi-5% yamandla, kwaye ngokukhawuleza iphelile. Ibhetri ye-nickel-hydrogen ihamba yonke indlela, ebonisa ukuba yayiyi-90% ekuqaleni, emva koko i-80%, kunye ne-70%.

Ubomi bebhetri bolu hlobo lwebhetri abukwazi ukwanelisa amandla angaphezulu asebenzisa amandla aphezulu eemveliso ze-elektroniki, ngakumbi xa ikhamera yedijithali idinga ukukhanya, kuthatha ixesha elide ukuthatha omnye umfanekiso, kwaye ibhetri ye-lithium-ion etshajekayo ayinayo. le ngxaki. Ke ukuba ikhamera ayiyiyo ibhetri ye-AA, iya kuba yibhetri ye-lithium-ion etshajwayo eyenziwe ngumenzi.

Olu lukhetho lokuqala. Ukuba ibhetri ye-AA, ungathenga ibhetri ye-nickel-metal hydride etshajwayo ngokwakho kwaye uthenge itshaja engcono. Kungcono ukukhupha kunye nokuhlawulisa kuqala, okuya kwandisa ubomi besiphango.

Iimpawu zokuthelekisa ibhetri ye-lithium kunye nebhetri eyomileyo:

1. Iibhetri ezomileyo ziibhetri ezilahlwayo, kwaye iibhetri ze-lithium ziibhetri ezinokutshajwa kwakhona, ezinokutshajwa kwakhona ngamaxesha amaninzi kwaye azinankumbulo. Akudingeki ukuba ihlawuliswe ngokobungakanani bombane kwaye ingasetyenziswa njengoko kufuneka;
2. Iibhetri ezomileyo zingcoliseke kakhulu. Iibhetri ezininzi zazinesinyithi esinzima njengemekyuri kunye nelothe kwixesha elidlulileyo, nto leyo ebangele ungcoliseko olumandla lwendalo esingqongileyo. Ngenxa yokuba iibhetri ezilahlayo, zilahlwa ngokukhawuleza xa zisetyenziswe, kodwa iibhetri ze-lithium aziqukethe isinyithi esiyingozi;
3. Iibhetri zeLithium nazo zinomsebenzi wokutshaja ngokukhawuleza, kwaye ubomi bomjikelezo nawo buphezulu kakhulu, obungaphaya kokufikelela kwiibhetri ezomileyo. Iibhetri ezininzi ze-lithium ngoku zineesekethe zokukhusela ngaphakathi.
