Challenges Associated with metal-air battery

SEI layer engineering and anode protection

Formation of SEI layer prevent the anode poisoning and dendrite formation

Electrolyte Compatibility and stability Cathode clogging and irreversible product formation Prevention of side Reactions with H2O and CO2

  • Increasing charging potential
  • Poisoning the anode
  • Irreversible reactions
  • Narrow Potential window
  • Insufficient ionic conductivity
  • Low solubility of some desired Li- salts
  • Difficulties in designing of an

efficient SEI layer

  • Limited cycle life

Metal Anode poisoning and corrosion Electrolyte instability and decomposition Advanced electro catalysts and Tailoring the Product phase and structure

  • Sluggish OER and ORR

at cathode

  • Low cell efficiency
  • Capacity loss

Side Reactions with H2O and CO2

Role of di-electric electrolyte and salt and electrolyte type Potential of formation of LiOH and Li2CO3 as the two major side-products in Li-Air batteries SEM images of various morphologies of lithium peroxide in discharged cathode.
