Ibhethri Lekhabhoni Eliholayo le-CSPower – Ubuchwepheshe, Izinzuzo

Ngokuthuthuka komphakathi, izidingo zokugcina amandla ebhethri emicimbini eyahlukene yezenhlalo ziyaqhubeka nokukhula. Emashumini ambalwa eminyaka edlule, ubuchwepheshe obuningi bebhethri buye bathuthuka kakhulu, futhi ukuthuthukiswa kwamabhethri e-lead-acid nakho kuhlangane namathuba nezinselele eziningi. Kulesi simo, ososayensi nonjiniyela basebenzisana ukwengeza ikhabhoni ezintweni ezisebenzayo ezingezinhle zamabhethri e-lead-acid, kwathi ibhethri le-lead-carbon, inguqulo ethuthukisiwe yamabhethri e-lead-acid, lazalwa.

Amabhethri e-lead carbon awuhlobo oluthuthukisiwe lwamabhethri e-Valve Regulated Lead Acid asebenzisa i-cathode eyenziwe nge-carbon kanye ne-anode eyenziwe nge-lead. I-carbon ekwi-cathode eyenziwe nge-carbon yenza umsebenzi we-capacitor noma 'i-supercapacitor' evumela ukushaja nokukhipha ngokushesha kanye nokuphila isikhathi eside esigabeni sokuqala sokushaja sebhethri.

Kungani imakethe idinga ibhethri le-Lead Carbon???

• * Izindlela zokwehluleka kwamabhethri e-lead acid e-VRLA ayisicaba uma kwenzeka ukujikeleza ngamandla

Izindlela ezivame kakhulu zokwehluleka yilezi:

– Ukuthambisa noma ukuchitheka kwezinto ezisebenzayo. Ngesikhathi sokukhipha i-lead oxide (PbO2) yeplate elungile iguqulwa ibe yi-lead sulfate (PbSO4), bese ibuyela ku-lead oxide ngesikhathi sokushaja. Ukujikeleza njalo kuzonciphisa ukuhlangana kwezinto zeplate elungile ngenxa yomthamo ophezulu we-lead sulfate uma kuqhathaniswa ne-lead oxide.

– Ukugqwala kwegridi yepuleti elihle. Lokhu kusabela kokugqwala kuyashesha ekupheleni kwenqubo yokushaja ngenxa yokuba khona kwe-sulfuric acid okudingekayo.

– Ukuncibilikiswa kwezinto ezisebenzayo zepuleti elibi. Ngesikhathi sokukhishwa, i-lead (Pb) yepuleti elibi nayo iguqulwa ibe yi-lead sulfate (PbSO4). Uma ishiywe esimweni esiphansi sokushaja, amakristalu e-lead sulfate epuletini elibi ayakhula futhi aqine futhi akhe ungqimba olungenakungeneka olungenakuphinde luguqulwe lube izinto ezisebenzayo. Umphumela uba ukwehla kwamandla, kuze kube yilapho ibhethri lingasebenzi.

• * Kuthatha isikhathi ukushaja kabusha ibhethri le-lead acid

Okungcono kakhulu, ibhethri le-lead acid kufanele lishajwe ngesilinganiso esingedluli ku-0,2C, kanti isigaba sokushaja ngobuningi kufanele sibe ngamahora ayisishiyagalombili okushaja. Ukwandisa amandla okushaja kanye ne-voltage yokushaja kuzonciphisa isikhathi sokushaja ngezindleko zokuphila kwenkonzo okuncishisiwe ngenxa yokwanda kwezinga lokushisa kanye nokugqwala okusheshayo kwe-positive plate ngenxa ye-voltage yokushaja ephezulu.

• * Ikhabhoni eholayo: ukusebenza okungcono kwesimo sokushaja okungaphelele, imijikelezo eminingi ihlala isikhathi eside, kanye nokusebenza kahle okuphezulu komjikelezo ojulile

Ukufaka esikhundleni sezinto ezisebenzayo zepuleti elibi ngenhlanganisela yekhabhoni eholayo kungase kunciphise i-sulfuration futhi kuthuthukise ukwamukelwa kweshaja kwepuleti elibi.

Ubuchwepheshe bebhethri le-Lead Carbon

Iningi lamabhethri asetshenziswayo linikeza ukushaja okusheshayo kungakapheli ihora noma ngaphezulu. Ngenkathi amabhethri engaphansi kwesimo sokushaja, asenganikeza amandla okukhipha okwenza asebenze ngisho nangaphansi kwesimo sokushaja okwandisa ukusetshenziswa kwawo. Kodwa-ke, inkinga eyavela kumabhethri e-lead-acid ukuthi kwathatha isikhathi esincane kakhulu ukukhipha kanye nesikhathi eside kakhulu sokushaja futhi.

Isizathu sokuthi amabhethri e-lead-acid athathe isikhathi eside kangaka ukuthola i-chargeback yawo yokuqala kwakuyizinsalela ze-lead sulfate ezazifakwe kuma-electrode ebhethri nakwezinye izingxenye zangaphakathi. Lokhu kwakudinga ukulingana ngezikhathi ezithile kwe-sulfate evela kuma-electrode nezinye izingxenye zebhethri. Lokhu kuna kwe-lead sulfate kwenzeka kuyo yonke imijikelezo yokushaja nokukhipha futhi ukweqisa kwama-electron ngenxa yemvula kubangela ukukhiqizwa kwe-hydrogen okuholela ekulahlekelweni kwamanzi. Le nkinga iyanda ngokuhamba kwesikhathi futhi izinsalela ze-sulfate ziqala ukwakha amakristalu awonakalisa ikhono lokwamukela i-electrode.

I-electrode enhle yebhethri elifanayo ikhiqiza imiphumela emihle naphezu kokuba ne-lead sulfate precipitates efanayo okwenza kucace ukuthi inkinga ingaphakathi kwe-electrode engemihle yebhethri. Ukuze banqobe le nkinga, ososayensi nabakhiqizi baxazulule le nkinga ngokufaka i-carbon ku-electrode engemihle (i-cathode) yebhethri. Ukwengezwa kwe-carbon kuthuthukisa ukwamukelwa kwebhethri kokushaja okususa ukushaja okungaphelele kanye nokuguga kwebhethri ngenxa yezinsalela ze-lead sulfate. Ngokufaka i-carbon, ibhethri iqala ukuziphatha 'njenge-supercapacitor' enikeza izakhiwo zayo zokusebenza kangcono kwebhethri.

Amabhethri e-lead-carbon ayindlela efanele yokufaka esikhundleni izinhlelo zokusebenza ezifaka ibhethri le-lead-acid njengasezinhlelweni ezivamile zokuqalisa kanye nezinhlelo ze-micro/mild hybrid. Amabhethri e-lead-carbon angaba nzima uma kuqhathaniswa nezinye izinhlobo zamabhethri kodwa ayabiza, amelana namazinga okushisa aphezulu, futhi awadingi izindlela zokupholisa ukuze asebenze eceleni kwawo. Ngokuphambene namabhethri endabuko e-lead-acid, lawa mabhethri e-lead-carbon asebenza kahle phakathi kwamaphesenti angama-30 nangama-70 okushaja ngaphandle kokwesaba imvula ye-sulfate. Amabhethri e-lead-carbon asebenze kangcono kunamabhethri e-lead-acid emisebenzini eminingi kodwa abhekana nokwehla kwamandla kagesi lapho ekhishwa njengoba kwenza i-supercapacitor.
