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.

Fuel Cell
A fuel cell is an electrochemical cell that converts the chemical energy from a fuel into electricity through an electrochemical reaction of hydrogen fuel with oxygen or another oxidising agent.
Fuel cells are different from batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy comes from chemicals already present in the battery.
Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied.
