If we listen to Peter Rawlinson''s description of the Lucid Motors battery design he points out that the base cooling design gives a more consistent thermal connection to the cell. In the end though this probably comes down to the package dimensions and whether you can fit a slightly taller base cooled design or a wider/longer side cooled design.
The major source of positive lithium ions essential for battery operation is the dissolved lithium salts within the electrolyte. The movement of electrons between the negative and positive current collectors is facilitated by their migration to and from the anode and cathode via the electrolyte and separator (Whitehead and Schreiber, 2005).
