The rechargeable battery, or secondary cell, that can be recharged by reversing the chemical reaction has been invented in 1859 by french physicist Gaston Plante. The electrolyte is a diluted sulphuric acid solution, the negative electrode is made of lead and the positive electrode is made of lead dioxide. A lead-acid battery is discharged when the sulphuric acid is turned completely into water and the electrodes in lead sulphate.
Another common type of battery is the alkaline cell, or nickel-iron battery, developed by the american inventor Thomas Edison in the years 1900. A disadvantage of the Ni-Fe cell is that, when recharging, hydrogen is externally eliminated as gas. Another alkaline cell type, similar to the above, is the Ni-Cd battery, in which the negative electrode is made of cadmium.
A large number of developments have been made in the field of rechargeable batteries as electric vehicles have become more popular. The Sun generates a huge amount of energy which is dissipated in Space, only a small fraction of this energy reaching Earth in the form of light and other radiations.
A solar power generator is comprised of two main parts: a collector unit, which receives incident radiation and converts a fraction of it into other forms of energy, electricity or heat and a power storage unit in which captured energy is stored. These are essentially flat plate connectors onto which auxiliary optical systems help focusing and thus maximizing the amount of incident radiation.
Photons in the incident light hit the cell, but only photons with a certain level of energy can set free electrons from the atomic bonds in the cell’s material, thus generating electrical current.
An individual photovoltaic cell can generate a power of 1-2 W, very little for most applications. The material of choice in photovoltaic cells manufacture is silicon, although several other materials can be used. Dan Mihai is an Automation and Computer Science graduate, he has a passion for robotics and is especially enthusiastic about wheeled mobile robots, AGVs and things with wheels in general. When the switch is closed and the battery is supplying current, 2 electrons are pulled away from the Lead atom: they’re attracted to the positive side of the battery.
At the same time, the Lead ion (Pb+2) reacts with the Sulfate part of the Hydrogen Sulfate ion (HSO4-), leaving a Hydrogen ion behind. When the Lead and Sulfate combine they form Lead Sulfate which precipitates onto the electrode surface.  Meanwhile, the electrons pass through the light bulb, heat the filament, and provide illumination!
The Lead (Pb2+) reacts with the Hydrogen Sulfate ion (HSO4-), releasing a Hydrogen ion, and the aqueous Oxygen ions react with the Hydrogen ions in solution.
Notice that since the electrons have passed through the bulb, no further light is supplied.  In an actual reaction, there are many, many millions of electrons so the battery would supply light for much longer. The Oxygen ions and Hydrogen ions combine (what do they form?), and the Lead and Sulfate ions also combine.  See what they become in the next drawing! As the battery continues to operate, the acid in the electrolyte is slowly replaced by water.  When it’s all water the battery is dead! Fortunately this reaction is reversible.  If we pass a direct current through the cell in the opposite direction, the Lead Sulfate dissociates back into Lead and Sulfate ions and the Water dissociates back into Oxygen and Hydrogen.  Lead Oxide is restored on the positive electrode and pure Lead on the negative side…and we can use it all over again! Electrical power systems are cheap, practical, easy to implement and can be used in any environment – even indoors, as no pollution takes place locally. When the battery is recharged, the chemical reactions described earlier take place in a reversed order, until chemicals are returned to their original state.
The principle of operation is similar to the lead-acid battery, in this case the electrolyte is a potassium hydroxide solution, the negative electrode is made of iron and the positive is made of nickel oxide. Despite the improvements made, rechargeable batteries still haven’t overcome their disadvantages in terms of reduced power, high price, bulkiness or environment pollution problems. Solar energy is, in principle, pretty easy to use, it is captured directly from the Sun and stored.


It is not an absolute requirement for a solar power system to have a storage unit but power availability will greatly depend to the highly variable amount of energy reaching the collector. This type is not very common and has several shortcomings, unlike flat plate collectors they do not receive radiation reflected from the soil, which can be significant in certain cases, and can reach very high temperatures, affecting the efficiency of silicon elements or even damaging them. These collectors absorb radiation and convert it into heat in a natural fashion, without necessarily being conceived for such purpose. The cells convert radiation into electricity but operate with a theoretical efficiency of 32%, the real-life efficiency being only around 15%, not very efficient from an economics standpoint.
This level of energy, known as dislocation energy, is defined as the quantity of energy required to set free an electron in a covalent bond, sending it into an electrical circuit.
Crystalline cells are very common and are made out of slices cut from silicon crystal billets, while in the case of thin-film cells, photovoltaic material is deposited in thin layers, 0,001 to 0,2 mm thick, on substrate layers made of glass, stainless steel or plastic. With all the alternative sources of energy being explored and implemented; we are seeing a rising trend in demand of Lead acid batteries. However electricity is used up at some time, at this point shortcomings of these systems come into play, long recharging times or bulkiness for large capacity systems to name just a few. The lead-acid battery has three or six cells, with a voltage of 2V per cell, connected in series and it is used in a wide range of vehicles, from automobiles or bikes to airplanes. The electrons pass through the external electrical circuit while the positive ions combine with sulfate ions in the electrolyte and form lead sulfate.
Sealed rechargable lead-acid batteries are a viable solution in alternate power supply systems. Almost any dimension is possible and the amount of generated energy directly depends on size, orientation and degree of cleanliness as these factors dirrectly affect the amount of incident radiation received.
All objects have the capacity to do this, to some extent, but only certain elements can be efficient in the process. During recent developments an efficiency of around 28% has been reached in lab conditions, but real-life performance has yet to be proved.
Photon energy must be at least equal to the dislocation energy in order for a photon to set free an electron. The working principle of the latter is similar to a diode, semiconductor layers in the thin-film cells being doped with electrons in order to form p and n junctions. However, these batteries have a high cost and you will need to spend quite some money to replace them (average life of commercially available deep cycle batteries is 1.5-2 years) when they die out on you. A way to constantly regenerate power, or at least to slow down depletion of energy resources is needed. Its great advantage is that it can provide strong current to start an engine even though its capacity is limited. When electrons reenter the cell at the positive electrode another chemical reaction takes place, the lead dioxide combines with hydrogen ions in the electrolyte to form water, releasing lead ions into the electrolyte to form again lead sulfate.
In the light of recent developments, batteries for certain applications have been made with a lifespan of 50 to 70 years. Their lifespan ranges between 4 and 6,5 years and they offer reasonable performance in small, medium and some large mobile robot applications, with capacities ranging up to 42-65 Ah per unit. In many cases these collectors also have automatic sunlight orientation systems to maximize efficiency. In many cases the natural capacity of an element to convert radiation into heat can be augmented, e.g. If high-energy photons hit the photovoltaic cell, energy that is not used by the the electron dislocation process is converted into heat, an efficient cell being the one that can convert as much photon energy as possible into electrical energy, not lose it to heat.
This is where we come in with our guide on how to rebuild a battery from your dead battery.
Here’s How You Can Still Start Your Car Advertisement By Admin - May, 8th 2014Car batteries need to be replaced every few years depending on the weather conditions, usage and type of battery installed in the car.


In the following we will take a look at elements which could be used to build electrical power sources for robots.
Dislocation energy levels vary between 1 to 1,6 eV (electron-volts) in efficient photovoltaic semiconductors. Some of us linger on with an old battery and end up getting stuck with a dead car battery on a cold morning. Alright, so how do you build a battery from an existing dead battery and more importantly why does the battery die? In such a case, the options are limited and most of us wish if the car could start one more time so that we could take it to the nearest workshop for battery replacement.If you are using a wet car battery that can be opened from the top, The good news is that there is a way you can still start your car without the need of another car for jump starting. Divide the two aspirin tablets in equal parts and drop each piece in the cell filler holes. This results in a decrease in battery’s capacity and consequently failure.You can recover the oxides (covered later in the article) from the positive plates that have fallen victim to the anodic corrosion and use it to make paste for the new plates.
So; we will be using the negative plates to make a new cell with the paste that comes from oxides. This means that you’ll be building a 3 cell battery from 6 cell battery.Advertisement Now to get to the job’ remove the positive plates and have them placed in a metal container, which can take some beating.
The battery will have enough juice to start the car for one more time.Now you can head to the nearest workshop and get your battery changed. Use a hammer or anything that is hard that can transfer impact to turn these plates into powder. Once you have crushed the plates, remove small pieces of lead and grid from the mixture by sieving the contents. Mix this powder with sulfuric acid and water to form a paste which will be placed into the plate’s grid structure and cured. Material fully grasp a great deal concerning this, just like you submitted the particular guide from it or something like that.. Mix the fiberglass and glass fibers that have been recovered from the separators to strengthen the paste. Once the paste has been applied you will need to cure the plates, which is usually done at 30 degree Celsius in high humidity for about 48 hours.
At home, just put them in a pot that is filled with water into the oven and keep an eye on the water level.
First off, cut the top off the battery and leave about 5 mm of plastic around the terminals. Now you need to cut the interconnection between the cells and remove the cells from the case.Now you need to perform the process of forming in which, active materials are formed on the new plates. The idea is to pass electric current and then reverse the direction and continue the same procedure for about say 30 times. If you continue indefinitely you’ll destroy the plate.Let’s make some electrolyte, shall we? Alternatively, you can buy a sulphuric acid solution with 1250 sp gravity from a battery shop to use as a battery electrolyte. Now all that is left is placing the plates back into the case, sealing the top and filling it with electrolyte. If you still decide to do it, make sure to work very safe as the lead-acid is very dangerous.
