Technion Researchers Develop Silicon-Air Battery Capable of Working
Non-Stop Thousands of Hours
The Technion has registered a patent on this development which was
published in the world=92s leading electrochemistry journal

Technion researchers have succeeded in developing a silicon-air
battery capable of working non-stop thousands of hours. The
development was published in the leading scientific journal
=93Electrochemistry Communications.=94

Prof. Yair Ein Eli of the Technion=92s Faculty of Materials Engineering
has been researching metal-air batteries for many years. The batteries
we are familiar with have a positive (+) electrode called a cathode
and a negative electrode (-) called an anode. The two are separated by
a divider in which there is a liquid containing ions (electrolyte).
=93In metal-air batteries there is a significant saving in weight and
costs because they actually do not have a built-in cathode,=94 he
explains. =93In this battery, the cathode is the oxygen that comes from
the atmosphere through the membrane (this is the battery used for
example for hearing aids because it is light and long-lasting). There
were attempts in the past to upgrade this battery both for electric
cars and for portable electronic devices. Lately, this received
renewed impetus when Toyota and Panasonic began joint efforts to adapt
the zinc-air battery for future electronic cars.=94
