In 1991, Chinese scientists pioneered a new type of battery made of aluminum air seawater as the material for use as a navigation marker light. The battery uses inexhaustible seawater as the electrolyte and generates electricity by continuously oxidizing aluminum with oxygen in the air. The electrode reaction formula is as follows:
Negative electrode: 4Al – 12e===4Al3+
Positive electrode: 3O2+6H2O+12e==12OH -
The total reaction formula is: 4Al+3O2+6H2O===4Al (OH) 3
The energy of this battery is 20-50 times higher than that of ordinary Dry cell!
New type of chemical battery
(1) Alkaline hydrogen oxygen fuel cell
This type of battery uses 30% -50% KOH as the electrolyte and operates below 100 ° C. The fuel is hydrogen, and the oxidant is oxygen. The battery diagram is (-) C | H2 | KOH | O2 | C (+)
The battery reaction is negative 2H2+4OH -4e=4H2O positive O2+2H2O+4e=4OH
Total reaction 2H2+O2=2H2O
Alkaline hydrogen oxygen fuel cells have been used in manned spacecraft in the United States since the 1960s, and have also been used in forklifts, tractors, etc. However, their prospects as civilian products are still uncertain. Negators believe that the electrolyte KOH used in batteries can easily react with CO2 from fuel gas or air, generating carbonate with poor conductivity. In addition, although the noble metal catalyst load required for fuel cells is low, their actual lifespan is limited. The affirmative believes that the material of the fuel cell is relatively cheap, and if natural gas is used as fuel, it is even cheaper than the only commercially available phosphate fuel cell.
