Lithium-air battery cathode material reaction
In general lithium ions move between the anode and the cathode across the electrolyte. Under discharge, electrons follow the external circuit to do electric work and the lithium ions migrate to the cathode. During charge the lithium metal plates onto the anode, freeing O 2 at the cathode. Both non-aqueous (with Li2O2 or LiO2 as the discharge products) and aqueous (LiOH as the dis. Lithium ions disperse from the anode during discharge and go to the porous cathode, where they react with ambient oxygen to generate lithium peroxide (Li2O2). [pdf]
FAQS about Lithium-air battery cathode material reaction
How does a lithium battery react with oxygen gas?
Oxygen gas (O 2) introduced into the battery through the air cathode is essentially an unlimited cathode reactant source due to atmospheric air. Because of this the air cathode is the most important component of the system. The lithium metal reacts with oxygen gas to give electricity according to the following reactions: Discharge
What is a lithium air battery?
The lithium–air battery (Li–air) is a metal–air electrochemical cell or battery chemistry that uses oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow. [ 1 ] Pairing lithium and ambient oxygen can theoretically lead to electrochemical cells with the highest possible specific energy.
How does lithium react with oxygen?
Lithium in the anode undergoes a redox reaction, and lithium ions (Li +) are constantly transported through the electrolyte to the cathode and react with oxygen molecules. Lithium oxide (Li 2 O) and lithium peroxide (Li 2 O 2) are generated in the air cathode. The general reaction are presented as:
How does a lithium-air battery work?
The lithium-air battery works by combining lithium ion with oxygen from the air to form lithium oxide at the positive electrode during discharge. A recent novel flow cell concept involving lithium is proposed by Chiang et al. (2009). They proposed to use typical intercalation electrode materials as active anodes and cathode materials.
How Lithium oxides form during recharging cycle?
Lithium oxides form during discharging cycle as lithium ions are transferred to the cathode and react with incoming oxygen. The recharging process involves the reduction of lithium oxides (Li 2 O and Li 2 O 2). However, Li 2 O is not electrochemically active and subsequently not participating reversible reactions.
Which material is used in a Li-air battery?
In typical Li-air batteries, oxygen gas is used as a cathode material along with a catalyst and porous carbon as a Li 2 O 2 reservoir in a cathode. Li metal is used as an anode which plays the basic role of Li source in Li-air batteries.
