Current flow in batteries?
$begingroup$ Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics. Not noticable at most voltages, but see what happens when you touch a peice of metal to a 100,000kV line, even in a vaccumm with no earth, a sizeable current will flow to bring the metal to the same electrostatic charge.

Lithium-ion batteries explained
Instead, battery cells are connected in series and parallel, into a so-called battery pack, to achieve the desired voltage and energy capacity. An electric car for example requires 400-800 V while one single battery cell typically supplies 3-4 V. A battery pack is a complete enclosure that delivers power to a final product, such as an electric car.

19.2: Electric Current
Some cells use two half-cells with different electrolytes. A separator between half-cells allows ions to flow, but prevents mixing of the electrolytes. Each half-cell has an electromotive force (or emf), determined by its ability to drive electric current from the interior to the exterior of the cell.
What are the Different Types of Batteries?
The electrochemical reaction in a battery involves transfer of electrons from one material to another (called electrodes) through an electric current. Cell and Battery. Even though the term battery is often used, the basic electrochemical unit responsible for the actual storage of energy is called a Cell.
