Letno poročilo 2005

prena{amo v slovensko industrijo. V letih 2004
- 2005 smo izku{nje, ki smo jih pridobili pri
raziskavah novih materialov za litijeve baterije,
uporabili pri optimizaciji delovanja baterij cinkzrak,
ki jih proizvaja podjetje Iskra TELA d.d.,
[entvid pri Sti~ni. Izkazalo se je namre~, da je
tudi pri tem tipu baterij potrebno pripraviti
pozitivno elektrodo z optimirano porozno
arhitekturo, ki zagotovlja simultani dostop
zraka, elektronov in ionov do ~im ve~jega dela
povr{ine elektrode. S tem maksimiramo
povr{insko gostoto katalitskih mest za elektrodne
reakcije, kar je klju~no za delovanje
baterije cink-zrak pri visokih tokovnih gostotah.
Izbolj{ano delovanje baterij cink-zrak je Iskra
TELI omogo~ilo sklenitev nove pogodbe, na
osnovi katere je to podjetje postalo eden od
vodilnih proizvajalcev specialnih baterij cink-zrak
v Evropi.

ners. In the period of 2004 - 2005 we used the
experience gained during the research of advanced
lithium batteries in optimization of a
zinc-air battery system produced by the national
battery producer Iskra TELA d.d., [entvid pri
Sti~ni, Slovenia. Like the electrodes in lithium
batteries, the zinc-air battery also requires a
carefully designed system of pores in order to
provide a simultaneous access of air, electrons
and ions to the electrocatalytic sites where the
electrochemical reactions take place. Optimization
of pore size and distribution, together
with other improvements, lead to a successful
maximization of current density and total capacity
delivered by the zinc air battery. Based
on these improvements, Iskra TELA has signed
new contracts which launched this company
among the most important European producers
of zinc-air batteries for special applications.
