2. Penny battery - Wikipedia

   en.wikipedia.org/wiki/Penny_battery

   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.

3. Lemon battery - Wikipedia

   en.wikipedia.org/wiki/Lemon_battery

   A lemon battery is a simple battery often made for the purpose of education. Typically, a piece of zinc metal (such as a galvanized nail) and a piece of copper (such as a penny) are inserted into a lemon and connected by wires.

4. Aluminium–air battery - Wikipedia

   en.wikipedia.org/wiki/Aluminium–air_battery

   Aluminium–air batteries (Al–air batteries) produce electricity from the reaction of oxygen in the air with aluminium. They have one of the highest energy densities of all batteries, but they are not widely used because of problems with high anode cost and byproduct removal when using traditional electrolytes. This has restricted their use ...

5. Aluminium-ion battery - Wikipedia

   en.wikipedia.org/wiki/Aluminium-ion_battery

   Rechargeable aluminium-based batteries offer the possibilities of low cost and low flammability, together with high capacity. [7] The inertness and ease of handling of aluminium in an ambient environment offer safety improvements compared with Li-ion batteries. Al-ion batteries can be smaller and may also have more charge-discharge cycles.

6. Zamboni pile - Wikipedia

   en.wikipedia.org/wiki/Zamboni_pile

   A Zamboni pile is an "electrostatic battery" and is constructed from discs of silver foil, zinc foil, and paper. Alternatively, discs of "silver paper" (paper with a thin layer of zinc on one side) gilded on one side or silver paper smeared with manganese dioxide [ 2 ] and honey might be used. [ 3 ]

7. Molten-salt battery - Wikipedia

   en.wikipedia.org/wiki/Molten-salt_battery

   Thermal batteries originated during World War II when German scientist Georg Otto Erb developed the first practical cells using a salt mixture as an electrolyte. Erb developed batteries for military applications, including the V-1 flying bomb and the V-2 rocket, and artillery fuzing systems. None of these batteries entered field use during the war.

9. Flexible battery - Wikipedia

   en.wikipedia.org/wiki/Flexible_battery

   In general, a battery is made of one or several galvanic cells, where each cell consists of cathode, anode, separator, and in many cases current collectors. In flexible batteries all these components need to be flexible. These batteries can be fabricated into different shapes and sizes and by different methods. [3]
