The lead-acid battery is still used today in automobiles and other applications where weight is not a big factor. The basic principle has not changed since 1859. In the early 1930s, a gel electrolyte (instead of a liquid) produced by adding silica to a charged cell was used in the LT battery of portable vacuum-tube radios.
Leclanché's "wet cell" (as it was popularly called) was the forerunner to the world's first widely used battery, the zinc–carbon battery. In 1876, Leclanché jellifies the electrolyte of his cell by adding starch to the ammonium chloride, making his cell more portable.
The penny battery experiment is common during electrochemistry units in an educational setting. Each cell in a penny battery can produce up to 0.8 volt, and many can be stacked together to produce higher voltages. Since the battery is a wet cell, the effectiveness will be reduced when the electrolyte evaporates.
A 1919 illustration of a Leclanché cell. The Leclanché cell is a battery invented and patented by the French scientist Georges Leclanché in 1866. [1] [2] [3] The battery contained a conducting solution (electrolyte) of ammonium chloride, a cathode (positive terminal) of carbon, a depolarizer of manganese dioxide (oxidizer), and an anode (negative terminal) of zinc (reductant).
A wet cell battery has a liquid electrolyte. Other names are flooded cell, since the liquid covers all internal parts or vented cell, since gases produced during operation can escape to the air. Wet cells were a precursor to dry cells and are commonly used as a learning tool for electrochemistry.

A typical flow battery consists of two tanks of liquids which are pumped past a membrane held between two electrodes. [1]A flow battery, or redox flow battery (after reduction–oxidation), is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane.
LAS VEGAS (AP) — Milwaukee coach Doc Rivers has heard and seen enough. He's convinced there will be an NBA team in Las Vegas. “Yeah, they're going to get it,” Rivers said.
