Products that are marked "On Order" in the "Available Quantity" column are usually not in stock. Such products are available for purchase, however, due to their limited customer base, they usually have higher minimum quantities. DACPOL offers products that are not in stock for the following reasons: DACPOL currently has a large number of electronic components in stock and adds new products every day, however, tens of thousands of additional components and their various variants are available from our suppliers. Even though it is unreasonable to have all these products in stock due to the limited sales, we believe that it is in the best interest of our customers to make them available. Our goal is to inform customers about the maximum number of products available and enable them to make decisions based on specifications, prices, availability, required minimums and our technical advice. Please note that selecting the "In Stock" checkbox may limit the display to only products available for delivery straight from the shelf.

What parameters are the most important for storing energy?

In terms of energy storage, two parameters are the most crucial: energy density and power density. Energy density describes the quantity of energy that can be stored in a given density. Power density is a method of how the energy can be stored in the device. The higher the value the shorter changing and discharging time. A perfect device for storing energy should connect these two parameters so they have the same values. In practice, this compromise is hard to achieve. 

What is a supercapacitor?

Today, LS Mtron supercapacitors offer a solution for this issue. They’re a compromise between batteries and conventional capacitors. They enable using new energy storing solutions, even considering that the density is still smaller than in conventional batteries.

A disadvantage of this technology can also be low voltage of a single element. It hesitate from 2,5 to 3V depending on a used electrolyte. To gain higher voltage, supercapacitors are connected in series into modules (with voltage up to 750 V). In traction vehicles, these devices are used for reducing energy waste through restoring and storing it during breaking. Stored energy is then used while moving or rapid accelerating.

Supercapacitors are characterised by high durability. Suppliers describe it in years (about 10 - 20) or in number of charging-discharging cycles (1 milion). It is easy to notice it’s an at least satisfactory durability, which in comparison to traditional batteries, is impressive. Another important trait is a wide range of work temperatures from -40 to 65°C. These devices, as opposed to traditional batteries, do not have in their enclosures toxic for the environment elements. A disadvantage of this technology is the price, which is higher than conventional capacitors or batteries.

Applications of supercapacitors

  • electric vehicles (trams, hybrid cars, electric cars);
  • backup memory (UPS, electronic devices, telecommunication, military);
  • power conditioning systems (DVR);
  • compact devices (laptops, mobile phones);
  • renewable energy resources (wind turbines, photovoltaic cells, energy storages).
