AI Technical Summary
The low discharge current and power density of lithium-air batteries result in insufficient actual discharge capacity. This is because the accumulation of solid lithium peroxide affects the mass-charge-electric coupling transport, leading to insufficient utilization of the electrochemical reaction interface and pore space.
The air electrode is split into an electrochemical reaction electrode and a solid product storage electrode. High-porosity porous media and high-conductivity catalytic active materials are used. The electrochemical reaction and solid product storage are separated by a buffer layer without lithium-ion electrolyte, thus achieving decoupling.
This improves the discharge voltage and discharge capacity of lithium-air batteries, achieving high power density and high capacity battery performance, while avoiding the influence of solid products on electrochemical reactions.
