Ngaba uyafuna ukwenza ibhetri isebenze?

Impendulo kukuba ibhetri kufuneka isebenze, kodwa lo akuwona umsebenzi womsebenzisi. Ndatyelela loo mzi-mveliso. Ngeentsuku zokuqala, iibhetri ze-lithium zahamba ngeendlela ezilandelayo:

I-electrolyte yeqokobhe yebhetri ye-lithium i-perfused-to-sealed, ihlawuliswe kwi-voltage engaguqukiyo, kwaye emva koko ikhutshwe. Lo mjikelo uphindwa izihlandlo ezininzi. I-electrolyte ininzi kwaye imanzisa i-electrode. Isakhono sokuvula sinamandla kwaye siyahlangabezana neemfuno. Obu buchule yinkqubo esebenzayo. Jonga i-Capacity yebhetri, khetha inqanaba lokwahlulwa kwebhetri yebhetri enemisebenzi eyahlukeneyo (umthamo), ukuhambelana kwamandla, njl njl. Iibhetri ze-Ni-Cd kunye ne-Ni-MH zinokuphinda zisebenze ngokuguqulwa kwefektri. Ezinye iibhetri ziyasebenza kwindawo evulekileyo kwaye zitywinwe emva kokwenza kusebenze. Le nkqubo inokwenziwa kuphela ngumenzi webhetri.

★Into ebizwa ngokuba yinkqubo yesibini nayo inokwenziwa. Umsebenzisi uzama ukutshaja kwakhona kwaye ayishiye ibhetri kaninzi kangangoko xa esebenzisa ibhetri entsha okokuqala.

● Kodwa ngokuqwalasela kwam (malunga neebhetri ze-lithium), ixesha lokugcina iibhetri ze-lithium ziinyanga ezi-1-3. Yintlawulo enzulu kunye nokusetyenzwa komjikelo onzulu, kwaye umthamo wayo wokuhamba uyenzeka awukho kwaphela. (Ndinengxelo yokuqinisekisa ibhetri kwicandelo leengxoxo.)

Ingaba kuthatha iiyure ezili-12 kwiimeko ezintathu zokuqala?

Le ngxaki inxulumene ngokusondeleyo nengxaki yokusebenzisa ibhetri ekhankanywe ngasentla. Ukucinga ukuba ibhetri yefektri ine-electrode passivation kwisandla somsebenzisi, kuthatha imijikelo emithathu enzulu yokutshaja kunye nokukhupha ukwenza ibhetri isebenze. Ngapha koko, ingxaki yokutshaja okunzulu azikho iiyure ezili-12 zokungahlawulisi. Ke elinye inqaku lam elithi “Ixesha lokuTshaja ibhetri yeSelfowuni” liphendula lo mbuzo.

Impendulo ayihlawulisi iiyure ezili-12.

Ngeentsuku zokuqala, ngenxa yembuyekezo yemfuno kunye nenkqubo yokutshaja i-drip yeebhetri ze-Ni-MH zefowuni ephathwayo, kungathatha malunga neeyure ze-5 ukufikelela kwimeko efanelekileyo yentlawulo endaweni yeeyure ze-12. Iimpawu zokutshaja eziqhubekayo zangoku kunye ne-voltage rhoqo zeebhetri ze-lithium zenza ixesha lokutshaja olunzulu lingaphantsi kweeyure ze-12.

Ngokomzekelo, ibhetri ye-600ma, setha okwangoku kwi-0.01C.6mA), ixesha lokutshaja kwe-1C alidluli imizuzu eyi-150, kwaye emva koko usethe okwangoku kwi-0.001 ° C (0.6mA), kwaye ixesha lokutshaja liyi-10 iiyure. Oku kusenokuba ngenxa yokuchaneka kwesixhobo. Ayinakufunyanwa ngokuchanekileyo ngoku, kodwa umthamo ofunyenwe kwi-0.01 ukuya kwi-0.001 degrees kuphela i-1.7 mA, kwaye umthamo ofunyenwe ngokutshintshiselana ngaphezu kweeyure ze-7 ungaphantsi kwe-3/1000, okungekho nto ebalulekileyo.

Ukongeza, kukho ezinye iindlela zokutshaja. Ngokomzekelo, xa indlela yokutshaja i-pulse yebhethri ye-lithium ifikelela kwi-4.2V yokubopha i-voltage, ayiyi kuphelisa kwinqanaba elincinci langoku, ngokuqhelekileyo imizuzu eyi-150 emva kwe-100% yentlawulo epheleleyo. Iifowuni ezininzi eziphathwayo ziqhutywa zii-pulses.

Abanye abantu basebenzise iiselfowuni zabo ukukhanyisa intlawulo kwiminyaka yokuqala, emva koko basebenzise isihlalo ukutshaja ukuvuma ubungakanani obugcweleyo befowuni ephathwayo. Le ndlela yokukhangela ayilumkanga.

Kubalulekile Isibane esiluhlaza esikhutshwa yitshaja ayilovavanyo lokwenyani lokutshaja.

★★ Khangela i-voltage xa ​​ibhetri ye-lithium ihlawuliswa (okanye ikhutshwe) yonke indlela emva kokufumanisa ukuba ibhetri ye-lithium ihlawuliswe ngokupheleleyo.

Eyona njongo yombane oqhubekayo wesigaba sangoku kukunciphisa ngokuthe ngcembe amandla ombane ongezelelweyo okubangelwa ukutshaja kwangoku kukumelana kwangaphakathi kwebhetri. Xa i-current iphantsi njenge-0.01c, njenge-6mA, imveliso yangoku kunye nokumelana kwangaphakathi kwebhetri (ngokubanzi ngaphakathi kwe-200 milliohms) yi-1mV kuphela, kwaye i-voltage ngeli xesha inokuthathwa njengombane webhetri ngaphandle yangoku.

Okwesibini, i-voltage yereferensi yefowuni ephathwayo ayifani ne-voltage yereferensi yokutshaja kwesitulo. Ifowuni ephathwayo icinga ukuba ibhetri igcwele kwaye ihlawulisa isihlalo, ngelixa isihlalo sicinga ukuba ibhetri ayigcwele kwaye iyaqhubeka ihlawula.
