A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.
Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery.
The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell.

Solid State Electrolyte
Most of the Li ion batteries use liquid electrolyte.
But All-Solid-state battery(ASSB) uses solid state electrolyte.
Solid state electrolyte has low Li diffusion, because of the intearface resistance, result in lower ionic conductivity than liquid electrolyte.
Due to Li dendrite, the battery, using liquid electrolyte has good ionic conductivity than ASSB, but it has a danger of fire belongs to Li dendrites caused short ciruit. But ASSB has solid electrolyte that can eliminate a danger of fire from Li dendrites.
