The positive side of a battery is only "positive" in relation to the "negative" terminal of the same battery. When you hook a wire from the positive terminal of the first battery to the negative terminal of the second, a very small amount of current will flow until the potential difference reaches zero.
Positive and negative current is just a difference in current flow. The reason I am asking is I am in a process of studying Inverter Field control for Hybrid vehicles. By switching the positive or negative post of the battery to the three MG (Motor Generator) connections a current starts flowing through the MG's coils.
Although these processes are reversed during cell charge in secondary batteries, the positive electrode in these systems is still commonly, if somewhat inaccurately, referred to as the cathode, and the negative as the anode.
As a result, the thickness of the negative electrode holds a greater sway over the ECD at the positive electrode than the initial SOC at the negative electrode. The ECD is susceptible to changes in the current collector area, which controls the flow of electrons between the electrode and the external circuit.
There's a tiny deficit of electrons on the battery's positive side, but once that equalizes (very quickly) there's now a tiny surplus of electrons on the battery's negative side. I'm sure there's atoms/molecules in the ground that could accept the extra electrons.
The factors are mentioned and affect the ECD at the positive electrode of a Li-ion (Li-ion) battery in different ways and to different extents. The order in which they affect the ECD depends on the specific battery design and operating conditions.

One half-cell includes electrolyte and the anode, or negative electrode; the other half-cell includes electrolyte and the cathode, or positive electrode. In the redox (reduction-oxidation) reaction that powers the battery, cations are reduced (electrons are added) at the cathode, while anions are oxidized (electrons are removed) at the anode. The electrodes do not touch each other but are ...
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). Between ...

A single inverter without a HUB connection is not a problem. Ground the positive terminal of the battery and move the DC breaker/disconnect from the positive conductor to the now ungrounded negative conductor. This would be like Inverter 1 in Figure 1 without the Inverter 2 and HUB connections. However, a destructive current path can be

When discharging a battery, the cathode is the positive electrode, at which electrochemical reduction takes place. As current flows, electrons from the circuit and cations from the electrolytic solution in the device move towards the cathode.

In a battery, the positive electrode (Positive) refers to the electrode with relatively higher voltage, and the negative electrode (Negative) has relatively lower voltage. For example, in an iPhone battery, the voltage of lithium cobalt oxide (LiCoO2) is always higher than that of graphite, thus LiCoO2 is the positive electrode material, while Graphite is the negative …
