The right metals for right recycling

The maximum number of charge-discharge cycles in the industry, two times less capacity to achieve the same electrical characteristics compared to lead-acid, fast charge with large currents and a stable discharge voltage, the ability to automatically control parameters are the advantages of lithium-ferric phosphate batteries . A wide range of these products, manufactured by EEMB, is used in power supply systems of base stations of cellular communication and automatic weather stations, solar power systems, emergency power supply systems, power supply of industrial electric drives and electric transport.

In recent years, the issue of improving mobile energy sources is more relevant than ever. 10-15 years ago, he was not so keen. But the best is the enemy of the good, and with the increased mobility of the urban dweller, i.e. With the transition from a desktop computer to a laptop, from a simple mobile phone to a smartphone, requests for mobile power sources have increased dramatically.

With the miniaturization of consumer electronics, its developers must withstand the general direction, reducing the size of power supplies while increasing their capacity. However, the question arises about changing not only the capacity of the batteries, but also the speed of their recharge and durability. After all, if the battery will recover the charge almost instantly, then it is not so critical how many hours the device can work without recharging.

The capacity of the battery, as well as its ability to recharge repeatedly, is also important for:

  • autonomous devices, focused on long-term maintenance-free – weather stations, gauging stations, soil stations;
  • alternative energy systems – solar and wind turbines;
  • electric vehicles – hybrid cars, loaders, electric cars.

In almost all these cases, batteries are operated in conditions far from ideal: at low temperatures, sub-optimal or incomplete charge cycles, high probability of deep discharge.

Among modern batteries, lithium occupies a special place. Lithium has a huge resource of energy storage, so the use of lithium-ion batteries in the role of energy storage for solar power plants and other sources of renewable energy is most beneficial compared to lead-acid batteries or other types of batteries. A special place among the batteries based on lithium ions occupy lithium-iron phosphate batteries.

For the first time, LiFePO4 as a cathode for a lithium-ion battery was used in 1996. This material interested the researcher in that, in comparison with traditional LiCoO2, it has a significantly lower cost, is less toxic and more heat-resistant. But the lack of it – a smaller capacity. And only in 2003, the company A123 System, under the leadership of Professor Jiang Ye-Ming, began to research lithium-iron phosphate batteries (LiFePO4).

The main properties of lithium-iron phosphate batteries

Lithium-iron phosphate batteries happen to be a subspecies of lithium-ion batteries that use iron phosphate as the cathode. Without exaggeration, they can be called the pinnacle of power battery technology. This type of battery in some parameters, in particular, the number of charge-discharge cycles, is superior to all others.
