Abstract:

To reach carbon neutrality before 2060, 80% of fossil fuels are to be replaced by renewable energy to decrease CO₂ emissions. In energy substitution, energy storage devices, such as Li-ion batteries, are widely used in the smart grid and electric cars. After 30 years of development, the energy density of Li-ion batteries reaches 300 mAh kg^-1. Solid-state Li-metal batteries are studied intensively to reach a high energy density of 500 mAh kg^-1 before 2030. In a solid-state battery, solid-state electrolyte plays an important role in improving electrochemical performance. In this report, an development on solid-state electrolytes will be introduced.

Keywords – solid-state electrolyte, Li-ion battery, smart grid, electric cars, CO₂ emission
