What is the working principle of methanol fuel-powered lithium-ion battery?

The working principle of methanol fuel-powered lithium-ion battery Direct methanol fuel-powered lithium-ion battery is a variant of proton exchange membrane fuel-powered lithium-ion battery, which directly uses methanol without pre-reforming. Methanol is converted into carbon dioxide at the anode, protons (hydrogen nuclei or hydrogen ions) and electrons, just like standard proton exchange membrane fuel-powered lithium-ion batteries. Protons migrate through the proton exchange membrane and react with oxygen at the cathode, while electrons pass through The load of the external circuit reaches the anode and performs work. Alkaline conditions in the negative electrode: 2CH3OH+16(OH-)-12(e)→2(CO32-)+12(H2O) in the positive electrode: 3O2+12(e)+6(H2O)→12(OH-) total Reaction formula: 2CH3OH+3O2+4(OH-)u003d2(CO32-)+6H2O Acidic conditions on the negative electrode: 2(CH3OH)-12(e)+2H2O→12H++2CO2 on the positive electrode: 3O2+12(e- )+12H+→6H2O total reaction formula: 2CH3OH+3O2u003d4H2O+2CO2 The expected operating temperature of this kind of battery is below 120 degrees Celsius, which is slightly higher than the operating temperature of a standard proton exchange membrane fuel-powered lithium ion battery, and its efficiency is about Around 40%. Direct methanol fuel-powered lithium-ion battery is a variant of proton-exchange membrane fuel-powered lithium-ion battery. It directly uses methanol without pre-reforming. Methanol is converted into carbon dioxide and hydrogen ions at the anode, just like a standard proton exchange membrane fuel-powered lithium-ion battery, and the hydrogen then reacts with oxygen.
