What Affects Lithium-Ion Battery First Efficiency（C）? Jul 14, 2022

What is pre-lithiation? For a full battery, the SEI film formed at the negative electrode interface will consume the lithium ions deintercalated from the positive electrode and reduce the capacity of the battery. If we can find another lithium source outside the positive electrode material, so that the formation of the SEI film consumes the lithium ions of the external lithium source, so that the ...
