Aluminum batteries

Aluminum batteriesNearly thirty years of searching for ways to improve the aluminum-ion battery is nearing its end. The first battery with an aluminum anode, capable of quickly charging, while being inexpensive and durable, was developed by scientists from Stanford University.

Researchers confidently state that their brainchild could well become a safe alternative to lithium-ion batteries, used everywhere today, as well as alkaline batteries, which are environmentally harmful. It will not be superfluous to recall that lithium-ion batteries sometimes ignite. Chemistry professor Hongji Dai is confident that his new battery will not light up, even if it is drilled through. Professor Day's colleagues described the new batteries as “ultra-fast rechargeable aluminum-ion batteries”. Due to its low cost, fire safety, and the ability to create significant electrical intensity, aluminum has long attracted attention ...

 

Ultra-thin multilayer solar cells based on nanostructured materials

Ultra-thin multilayer solar cells based on nanostructured materialsScientists all over the world are paying great attention to improving solar energy conversion systems. In an effort to increase their efficiency and reduce, as much as possible, the cost of producing solar cells, the scientists at the Massachusetts Institute of Technology decided to take the path of reducing the thickness of solar cells.

The new type of panels can surpass any such solutions, and in terms of electricity production per kilogram of material used, it will be inferior only to uranium. Such panels can be made of sheets of graphene or molybdenum disulfide folded into many layers, the thickness of which is only one molecule (stacks of monomolecular sheets). Scientists argue that this approach will ultimately become the best possible approach to the development of solar energy.

Solar windows - transparent solar concentrators

Solar windows: transparent solar concentratorsA team of researchers from the University of Michigan, led by Richard Lunt, has developed a unique solar concentrator that can convert only part of the solar spectrum into ultraviolet, which is not perceptible to the human eye. The material is transparent to visible light, which means that such transparent solar panels can be easily inserted instead of window glass, while the window will look completely familiar, like ordinary glass in it, but electricity will be generated along the way. The development was called "transparent luminescent solar concentrator."

Colored luminescent solar concentrators are already widely known, in which part of the spectrum of the radiation incident on the concentrator is absorbed in the colored upper layer, then reradiated with a longer wavelength. Then through the second, transparent layer ...

 

The largest lithium battery in the world

The largest lithium battery in the worldIn early November 2014, California-based energy company Southern California Edison announced its decision to enter into a 20-year contract with AES Energy Storage, a manufacturer of battery-powered electric energy storage systems. AES already manages the world's largest commercial battery network, each with 200 megawatt-hour capacity.

The company claims that the total capacity of currently developed batteries around the world is approximately 1 GWh. In this regard, the parent company AES Corporation received $ 16 billion in revenue last year. However, the now planned project will have to surpass all previous facilities ever built by the company.

A huge 400 megawatt-hour battery will be built south of Los Angeles, in Long Beach, at the Alamitos Power Center. It will have to provide peak loads ...

 

5 unusual designs of wind generators

5 unusual designs of wind generatorsWind energy is actively developing around the world, and it is no secret to anyone that this is one of the most promising areas of alternative energy at the moment. By mid-2014, the total capacity of all installed wind generators in the world was 336 gigawatts, and the largest and most powerful vertical three-bladed Vestas-164 wind generator was installed and launched in early 2014 in Denmark. Its power reaches 8 megawatts, and the span of the blades is 164 meters.

Despite the long-running technology of manufacturing vane turbines and windmills in general, many enthusiasts seek to improve the technology, increase its efficiency and reduce negative factors. As you know, the wind energy coefficient of use of traditional wind generators in the best case reaches 30%, they are quite noisy and violate natural heat balance of nearby territories...

 

Flexible rechargeable batteries

Flexible rechargeable batteriesIt’s no secret to anyone that batteries are firmly embedded in the everyday life of modern people. These are the power sources of our cell phones, digital cameras, camcorders, tablets and laptops - you can list endlessly. As for the accurate medical devices, portable devices, this is the most serious situation, because human life can be at stake.

Despite the achievements of the battery industry, such as lithium batteries of any shape and any desired size, progress in this area does not stand still, and here is the next innovation - a flexible battery.

This is an elastic polymer battery. If with a liquefied electrolyte there could be problems associated with safety due to the destruction of the release film during heating during operation, then in the case of a polymer, the stability of materials ...

 

Lithium ion batteries

Lithium ion batteriesThe principle of operation of any electric battery is the accumulation of electrical energy during the chemical reaction that occurs when the charging electric current flows through the battery, and the generation of electric energy when the discharge current flows during the reverse chemical reaction.

The reversibility of the chemical reaction in the battery allows you to repeatedly discharge and charge the battery. This is the advantage of batteries over disposable current sources, ordinary batteries, in which only discharge current is possible.

As the medium for charge transfer from one electrode of the battery to another, an electrolyte is used - a special solution, due to the chemical reaction of which with the material on the electrodes, both direct and reverse chemical reactions in the battery are possible ...

 

ROBITON PM - electricity meter in every outlet!

ROBITON PM - electricity meter in every outlet!

ROBITON RM-1, RM-2 - ethen outlet electricity meters or household wattmeters.Unique instruments allow you to measure with high accuracy the amount and cost of electricity consumed, the power of the connected load, and the PM-2 also measures the voltage and frequency of the mains, the current consumed by the load and power, and takes into account the two-tariff day-night payment system. At the same time, the price of devices is such that it makes them affordable for any home.

However, first things first! The meter of consumed electricity - wattmeter ROBITON PM-2 is designed to measure the consumption of electricity by household appliances. In PM-2, you can enter the price of kilowatt hours and find out the total cost of electricity consumed by the connected electrical appliance, for example, for a month.Since two pricing modes are implemented, this model is suitable for ...
