Investigation of the influential values about the use of the lead electrochemical system

Abstract

For the purpose of making a lead battery of the standard quality, characteristics of the exploitation depending on influential values, were tested: currents, temperatures and containing level of the antimony in electrode alloys lead-antimony, what is the essence and main goal of the processed problems in work. Researches were done by performing many experimental measuring on five brand new, dry filled, lead batteries of the same type, with the nominal voltage Un = 12 V and the nominal capacity qn = C20 = 44 Ah, with the standard values in processes of charging and discharging. Obtained results demonstrates that while discharging battery with the help of higher currents than nominal and lower temperatures then room temperature, but with the most optimal containing antimony level in electrode alloy, utilization is smaller than nominal.

Radi dobijanja olovnog akumulatora propisanog kvaliteta, ispitivane su karakteristike iskorišćenja u zavisnosti od uticajnih veličina: struje, temperature i sadržaja antimona u elektrodnim legurama olovo-antimon, što predstavlja suštinu i glavni cilj obrađene problematike u radu. Ispitivanja su vršena setom eksperimentalnih merenja na pet nova suvo napunjena olovna akumulatora istoga tipa, nominalnog napona Un = 12 V i nominalnog kapaciteta qn = C20 = 44 Ah, sa propisanim vrednostima veličina u procesima punjenja i pražnjenja. Dobijeni rezultati pokazuju da se pri pražnjenju akumulatora većim strujama od nominalne i pri nižim temperatura od sobne, ali sa najoptimalnijim sadržajem antimona u elektrodnim legurama, dobijaju manja iskorišćenja od nominalnih.
