When it comes to accumulators everyone thinks of batteries lithium-ion or lead-acid, there are very few people who are projected to accumulators that work with saline solutions, yet there arebatterieswhere cathode and anode are immersed in harmless solutions for the environment, this is the case ofbicarbonate batteriesor very Italian salt batteries. Before offering you the operating model of abicarbonate battery we focus on the Italian applications of salt accumulators, which have become a cult in the electric mobility sector in some foreign countries.
The technology ofsalt batterieswas developed by FIAM,Italian Factory Accumulators Motocarri Montecchio. FIAMM produces about 70% of its turnover abroad, operating in 60 countries with 3300 employees worldwide and 1200 in Italy.
The research center was created in the Italian headquarters where innovations in the field of industrial accumulators are studied,salt batteriesand horns. In the historic center of Rome, the service of children electric busesjust use the salt batteriesand not only: thesalt batteriesof FIAMM are used in Sao Paulo, Brazil in Riyadh in Saudi Arabia and are very well established in other parts of the globe. Although the most common remain thebatterieslithium-ion, other solutions are emerging on the market, just like the one offered bysalt batteries, sodium nickel chloride batteries made in Italy for some years.
These batteries have a high resistance to thermal shock and are inexpensive because they do not use rare materials. Because we told you aboutsalt batteries? Simply because every occasion is good to talk to you about made in Italy!
Returning to the accumulators albicarbonate, it uses two lead plates and sees the use, as an electrolyte, of a solution based onsodium bicarbonate. The electrolyte is obtained by dissolving half a teaspoon of sodium bicarbonate in water. To charge the accumulator, the two lead plates must be connected one to the positive pole and one to the negative pole of a 4.5 Volt battery.
