Any liquid or a moist object that has enough ions electric conductive can function as an electrolyte for a cell. Basically, you only need to insert two electrodes made of different metals into damp objects and chemical reactions occur when two metals react through moist cells.
Of course, this type of battery cannot be used practically except maybe turning on a small clock for a very short time. If you are looking for lithium-ion batteries then you can buy lithium ion vape batteries through https://vapebatteries.net/.
Basically, the amount of energy you get (volts) is determined by how much chemical reaction you do get between two metals. For this reason, lithium batteries are the latest and the biggest since milk powder.
Lithium is a very reactive alkali metal. Lithium will react if left open in the humid air. Combining with hydrogen in water molecules in the air will change from a whitish metal becomes black before your eyes. Lithium is also very high flammable, so if it's burned, throwing away water will only make it burn more.
Lithium metal needs to be watered with special chemicals to extinguish the fire. Lithium is also the lightest heavy metals (number 3 on the periodic table of elements). They both features, light and lots of potential energy, make lithium metal great for use in a battery.
The highly reactive lithium feature is also a weakness in the battery manufacturing industry. Lithium batteries give off a lot of heat and are known to burn on their own. For most people who use batteries, battery life is the most important aspect.
