Researchers at the International Advanced Research Centre for Powder Metallurgy & New Materials (ARCI) have developed a non-expensive way to coat carbon on lithium metal oxide electrodes for lithium-ion batteries Lithium-ion batteries

• Lithium-ion batteries are the most commonly used power source for electric vehicles
• The active components of lithium-ion batteries are:
  • Cathode- Lithium metal oxides or lithium metal phosphates
  • Anode- Commercial graphite
  • Electrolyte- Lithium salt dissolved in organic solvents.
• Carbon is the best choice of coating material to improve the cyclic stability of the active materials.
• Carbon coating on the active materials can double the lifetime of the lithium-ion cells.
