When Nikola Tesla first proposed using aluminum air batteries to power American homes, the idea was ridiculed as another crazy idea for him.
In fact, the power company he helped create with the AC (AC) delivery system was the driving force behind the idea.
Tesla is hundreds of years away from his time.
The green movement has accepted the homemade version of the metal.
For more than 20 years, air batteries have been using equipment such as "energy burritos" to provide short-term power to the ecosystem
Users with ideas in case of emergency.
While these self-made devices are easy to produce for the secondary school science expo, a more advanced model has the potential to provide much-needed electricity to developing countries or areas with unreliable power infrastructure or lack of solar energy resources.
The basic chemistry behind the BatteryAll metal/oxygen battery uses the same basic chemistry to work.
In the case of an aluminum air battery, the exact chemical reaction is 4Al 3O2 6H2O → 4Al (OH) 3.
This reaction also produces about half a volt of current.
Regardless of the size of a single battery, each battery of the air aluminum battery produces a consistent half-volt voltage.
However, the size of the battery will determine the frequency of aluminum to be replaced and the residue to be cleaned.
The oxidation reaction that takes place in the battery produces a hydroxide gel (a common ingredient in acid reflux) that must be cleaned from the surface of aluminum to allow the chemical reaction to proceed.
Reasons for potential capacity metals
The potential capacity of a single unit is of scientific concern to the air battery.
Consider the capacity of a standard nickel battery with a specific energy of 50 wh/kg (per kg watt hour) and a lithium ion battery with a specific energy range between 85-150 wh/kg.
Estimated air capacity
Aluminum battery is 380-
455 wh/kg or more than three times the capacity of the lithium ion model.
The study of aluminum air batteries has the potential to help develop large-scale portable energy sources for remote areas of the planet.
Metal in the real world
The air battery is in use-Zinc-
An example is the air hearing auxiliary battery.
In fact, the study of metals
Air batteries were used 25 years ago.
The renewed interest in this chemical battery is due to advances that enable a large number of aluminum alloys to be produced at a very low cost.
Who is interested in this technology?
S. military, hybrid automakers, third-world countries and portable electronics makers topped the list.
Initial US military research focused on creating reliable, lightweight power supplies for military and space applications.
Because weight and battery life are the main concerns, aluminum is the best choice for metal "fuel" because of its light weight, very high energy density and recyclable.
Unfortunately, the first aluminum air battery was very expensive to produce, with limited application only in underwater vehicles and special forces long term warranty packs.
Today, the military re-invested the technology in the hope of developing a lightweight "personal power station" that can be carried by ground soldiers as a way to charge and run integrated computer and communication equipment on site.
Automakers have been looking for ways to reduce vehicle weight without compromising performance or safety.
Having a battery system that is light in weight and high in power may reduce the weight of the vehicle by 500.
Make power a viable power source for hybrid engines.
Many car companies are working on lithium air batteries, but Toyota has tried a nickel-aluminum air battery that has the potential to reduce the weight of Prius by more than 750.
Some personal aluminum
The energy density of the air fuel cell may be 75 times that of lithium
The ion fuel cell means that laptops, mobile phones, PDA, tablets and all other types of personal entertainment devices can use more footprints on components and less footprints on batteries, reduce weight and improve performance.
The most interesting place this technology can (and should) be used is in developing areas where there is no ready-made grid in the world.
Research on aluminum air batteries has led to the development of large battery libraries that can be used for sanitary and construction work in third world countries.
This can include simple water purification systems, medical diagnostic tools, and even electricity for the entire house or community until the infrastructure is in place.
How to make aluminum air battery make your own aluminum air battery, you need the following easy-to-get materials;
Aluminum foil, activated carbon, salt, water, bowl, paper towel, two clip leads and DC motor.
Once you get the materials, a place on the kitchen counter will start assembling the batteries.
Create saturated brine by filling the bowl with water, then pouring salt and stirring.
Once you can't dissolve more salt in the water, you're done.
Spread a piece of aluminum foil beside the bowl.
Fold the paper towel in one piece, soak it in a bowl, and then cover the aluminum foil with a towel.
Cover the towel with activated carbon.
Place one lead on the charcoal and clip the other onto the aluminum foil.
Fold over the aluminum foil to create a package (roll cake if you want) and connect the lead to the DC motor.
Nothing will happen yet.
Press on the aluminum foil and the motor should rotate.
The harder you push, the faster it will spin.
The motor stops when you release the pressure.
Due to the scalability of aluminum air batteries, they can also be used for small or large-
Scale applications.
Anyone who needs a faulty safe backup of an electrical system may be a potential customer.
Grocery stores can use it to keep freezers and coolers running, and telecom and Internet service providers can use it to eliminate the chance of service loss due to power outages, in fact, anyone who runs a business that relies on electricity to deliver products to customers can use aluminum
Air battery as backup power supply.
