Iibhetri Lithium - ephunyeziweyo yokutshintsha ebalaseleyo ialakalin kunye saline nabalingani

iibhetri Lithium, njengokuba igama lixela, ziqaliswe soft metal kwealkali phantsi kwegama "Lithium". Le nto yendalo akhanya zonke iintsimbi ezaziwayo. Kuyinto elula ngaphezu kwamanzi ngenxa yoko ukubagcina, hayi kuphela isisombululo zolwelo kodwa nkqu separafini. Ngako oko, oko inako ebanzi electrochemical Lithium elivumela ngokukhuselekileyo bacinga metal yayo kakhulu esebenzayo.

iibhetri Lithium, waqala ngenxa yawo, kufuneka iparameters eliphantsi ubunzima-mbini, kunye nexabiso mninzi namandla ngokwaneleyo phezulu.

Okulungileyo, ophethwe ngamnye ibhetri lithium, zezi:

1. Small samozaryada current ixabiso. Oku kwenza kube lula ukwandisa ubomi lweenkonzo kwimeko opholileyo ngu izihlandlo eziliqela xa kuthelekiswa kunoogxa obrak.

2. Akukho mfuneko yokuba recharge ngamaxesha bathi umthombo wamandla wangaphandle.

3. Phantse akukho ukulahlekelwa umthamo kwiqondo lobushushu voice ephantsi, nto leyo eyenza lithium neebhetri sele iimeko Arctic.

4. ubomi inkonzo Long.

5. ubunzima Low.

Abavelisi avelisa neebhetri Lithium kunye ikhemikali kuqamba ezahlukeneyo ukunika iimveliso ezijoliswe ezahlukeneyo ombane yokusebenza, kwakunye ukuba ukusetyenziswa kwamandla ezahlukeneyo.

Avamise kakhulu neebhetri Lithium kwezi ndidi zilandelayo:

1. Li-MnO2 kunye ombane rated-3 V. Le hlobo luqhelekileyo. Uye umthamo ephakamileyo ngokubanzi lobushushu uluhlu lokusetyenziswa. Nmb makanikelwe ezikhoyo ubukhulu obukhulu.

2. Li-FeS2 okanye zhelezodisulfidnye Li-ibhetri. Ikhutshwe kwi ombane 1.5 V kwaye ukumela indlela elihle lokuba saline kunye obrak neebhetri. Ixabiso encinane na amandla ombane ikuvumela ukuba usebenzise ngqo kubo izixhobo.

Izinto eziluncedo ze olu hlobo ibhetri zimi ngolu hlobo lulandelayo:

A) Ixesha zokusebenza elide kunokuba nama-4 phinda xa kuthelekiswa kunye neebhetri obrak.

B) Ubunzima liye lathotywa ngama-30%.

B) futhe enkulu.

ubomi D) Ubude idlula iminyaka eli-10.

Ukunqongophala nje omnye: iindleko eziphezulu.

3. Li-Ion okanye Li-ion. Efumanekayo kuluhlu yombane rated ka-3.5 ukuya 4 V. I Amandla olu hlobo, intsimbi lithium luthathelwa ion zayo, yakwazi ukuba benze umsebenzi ekhuselekileyo. Olu hlobo ibhetri uyakwazi ndingamcinezeli, ngoko ngokufuthi kuthiwa iibhetri. Ewe abawuthobeli ebizwa ngokuba "isiphumo memory" kwaye ikwazi ukusebenza eliphezulu amandla. Kwimo opholileyo, i-self-obhobhozayo, apho malunga ne-5 ekhulwini ngenyanga nganye. Sensitive kumaqondo obushushu aphezulu.

Ekubeni lithium yinto metal esebenzayo, imveliso iibhetri lithium isoloko iimfuno ezikhethekileyo nzima ukuze akhuseleke. Le but is ngenkuthalo idityaniswe namanzi kukhokelela ekudalweni nasekusungulweni yeehidrojeni kwealkali. Ngaphezu koko, akukho mntu ukuphepha ukuxuba oksijini kuba oku kubangele ukwanda.
