Conventional current flow is opposite electron flow. Current flows in a loop from source to load and back to source. Interestingly, electron flow is very slow compared to the speed of electricity. It is usually less than 1mm/second while electricity flows at 50% to 90% of the speed of light. Electricity travels as an electromagnetic field.
batteries
When the battery is supplying power (discharging) to, e.g., the starter motor, the direction of the electric current is out of the positive terminal through the load and into the negative terminal.. Within the wire and frame, the electric current is due to electron current which is in the opposite direction of the electric current.. Within the (lead-acid) battery, the …
Examining Failures in Lithium-ion Batteries
The excessive current flow into the lithium-ion cell causes overheating and lithium plating, which leads to battery failure. When the current is in excess, the excessive joules will initiate more heat into the cell, causing overheating. The overheating leads to increased cell temperature hence failure.

The only path the current can take is from battery +ve to battery -ve. Current in the wire between the load and ''ground'' is flowing towards ''ground'', and current in the wire from ''ground'' to battery -ve is flowing away from ''ground'', but no current can flow into or out of the ''ground pin'' itself because there is nowhere for it to go.

In other words, why do we need to connect the battery positive to the negative to get electron flow? As far as I know, voltage difference is what drives current flow. From what I understand, there''s a surplus of negative charge (electrons) in the positive end of a battery (weird I know, but I guess they do it for mathematical reasons).
