Iasidi ye-Lead vs. iibhetri ze-lithium-ion: Ukutyhila umdlalo wamandla
Ukuqulunqa
Ilifa leebhetri ze-asidi yelothe
Okokuqala yatyhilwa ngo-1859, iibhetri ze-asidi ye-lead sele zikho ngaphezu kweminyaka eyi-150. Ngaphezulu kwenkulungwane enesiqingatha, ezi bhetri ziye zanika amandla yonke into ukusuka kwizithuthi zombane zakuqala ukuya kwiinkqubo zokhuseleko ezingxamisekileyo. Ubomi babo obude kwiimarike buthetha ngokubanzi malunga nokuqina kunye nokusebenza kwabo.
Iibhetri ze-lead-asidi zi iibhetri yesibini ezisebenza kwi-a umgaqo othe ngqo we-electrochemical. Baxhomekeke ekuphenduleni phakathi kwe-lead dioxide (PbO2) kunye ne-sponge lead (Pb) kwi-sulfuric acid (H2SO4) electrolyte. Ibhetri iqulethe i-lead dioxide njengepleyiti ekhangayo, isiponji ilothe njengepleyiti engalunganga, kunye nesisombululo sesulfate yelothe ehlanjululwe njenge-electrolyte.
Ukusabela kwemichiza okwenzeka ngaphakathi ebhetri kuko okubangela ukuba ivelise umbane. Emva koko, inkqubo inokubuyiselwa umva ukutshaja ibhetri kwakhona, ukwenza iibhetri ze-lead-asidi ziphinde zitshajwe.
Izinto ezintsha ezityhalela ukubuya kwe-lead-asidi
Imakethi yebhetri ibone ezimbini ezibalulekileyo Ezintsha xa kuziwa kwiibhetri ze-lead-asidi. Ezi ziibhetri ze-lead-crystal kunye ne-carbon foam.
Iibhetri zeLead-crystal uphawu lwenguquko kubuchwepheshe bebhetri ye-lead-asidi ngokuzisa ukwamkelwa kwentlawulo engcono, ukutshaja ngokukhawuleza, kunye nobomi obude. Benza oko ngokubandakanya izongezo zekhabhoni, eziphucula ukusebenza kweebhetri zelead-asidi zemveli, ukujongana nemiba efana ne-sulfation kunye nomjikelo wobomi obunyiniweyo.
Ezi zibonelelo zenza ukuba iibhetri zekristale zilungele usetyenziso olufuna ukutshaja rhoqo kunye nokukhupha imijikelo. Oku kuquka iiprojekthi zamandla ahlaziyekayo, iziseko zonxibelelwano ngomnxeba, kunye neenkqubo zobonelelo lombane olungaphazamisekiyo (UPS).
Ngelo xesha, iibhetri ze-carbon foam ukuhambisa amaxabiso aphezulu, okwenza ukuba alungele izicelo ezifuna ukugqabhuka kwamandla okukhawulezayo. Bazisa i-dimensional-dimensional emithathu, isakhiwo se-porous carbon njenge-anode kunye ne-cathode.
