Lithium batteries

Lithium batteries are used to store energy and use it for domestic or industrial purposes. These batteries have found their application in various areas of life: road and rail transport, gadgets (smartphones, tablets, laptops), mechanical engineering, special medical and computer equipment. They provide high-quality electricity supply for short-term or permanent use. The installations are constantly being improved, so you get a high-quality and safe-to-use device for powering both the simplest household and technical equipment.

Reliable and productive: the advantages of lithium batteries

The composition of the device includes anodes located on copper foil and cathodes located on aluminum foil. The cathodes and anodes are separated from each other by a separator with a porous structure. When turned on, lithium ions penetrate the crystal lattices. A chemical reaction occurs, during which chemical energy is converted into electrical energy. If you are unsure whether to buy lithium batteries, check out their benefits.

1. Fast charging. It takes a little time to recharge such a model.
2. High energy density. The batteries are extremely efficient. They are purchased as not only a backup, but also the main source of electricity.
3. Minimum self-discharge. If the battery is not used, it will self-discharge by a maximum of 20% per year.
4. Resistant to temperature changes. In the Etsenergy store you can buy models that can withstand -20°C in winter and +60 in summer.
5. The voltage is higher than nickel-cadmium alternatives.
6. Light weight. For example, the LifePO4 LogicPower AK-LP20961 battery weighs only 3.7 kg.
7. Tightness. The device can be used in any position.

You can buy lithium batteries in Kyiv or any city in Ukraine and use them immediately after purchase. There is no need to “train” the unit by completely discharging and then fully charging it.

Lithium batteries: the optimal solution for high loads

Depending on the chemical composition, lithium batteries are divided into several groups. The Etsenergy store offers the following models.

1. Lithium-ion. Used for charging mobile phones, tablets, laptops. They are worth buying to power electric vehicles ( electric scooters , electric bicycles), as well as equipment for medicine or industry. They are characterized by low cost and fast recharge time from the network. For long-term operation, you need to monitor the temperature regime, avoiding use at excessively low or high temperatures.
2. Lithium iron phosphate. Durable devices capable of operating in extremely low winter or extreme summer temperatures. For example, LifePO4 LogicPower AK-LP20899 remains operational in the temperature range from -15 to +60°C. It is worth buying such a model for domestic and industrial use if a large supply of electricity is required.

If you want to buy lithium batteries, pay attention to the technical characteristics of the product. So, when buying a unit, take into account its capacity, starting current, size, weight, operating temperature. Remember that for safe and long-term operation of the unit, it should not be allowed to overheat.

Etsenergy store offers lithium-ion and lithium iron phosphate models from trusted manufacturers. You can buy lithium batteries in Kyiv and any city in Ukraine in one click on the website or by phone. The best products from trusted manufacturers are promptly delivered by Nova Poshta anywhere in the country.

Technologies and types of lithium batteries

Lithium batteries are reliable energy storage devices that are used in various areas of life. The operating principle of such a device, like all rechargeable batteries, is based on plates with a positive and negative charge. The electrolyte is located between the plates.

The operating principle of such a device can be considered using the example of a lithium-ion battery. Graphite (negative charge) and lithium oxide (positive charge) are used as active substances, which are thinly layered onto the foil. The foil sheets are separated from each other by a separator, which is soaked in electrolyte. When a power source is connected to the battery, lithium atoms begin to leave the lithium oxide. When discharged, lithium ions tend to return to their positions.

In addition to lithium-ion batteries, you can buy lithium batteries of other types.

• Lithium polymer. The characteristics are similar to Li- ion . They come in a variety of forms so they can be purchased for many devices.
• Lithium-titanium. Lithium titanate is used at the anode . Suitable for those for whom fast charging is important. They are in demand in the automotive industry.
• Lithium iron phosphate. Many people want to buy this model because it remains functional in extreme temperature conditions. This model can easily withstand temperatures down to -30.

When choosing which lithium batteries to buy, carefully study their characteristics to choose the best option for your individual needs.

Safety of use and recommendations for maintenance of lithium batteries

Lithium batteries are known for their high energy density, but also have a number of safety features. In order for a lithium energy storage device, no matter what type it is, to last a long time, follow the rules of its operation.

When you decide to buy lithium batteries in Kyiv and other cities of Ukraine, carefully study the instructions. Various manufacturers provide recommendations for the optimal use of batteries. Such batteries, as well as all other acid storage devices, must be handled with care in order not only to maintain their productivity, but also to prevent situations that are potentially hazardous to your health, such as short circuits.

• Do not wait until the discharge reaches 0%. Such a device must be charged in time, before the unit is completely discharged. This way you will extend the life of the battery. If there is about 10% charge left, you need to recharge the battery. You should also avoid overcharging, which has a detrimental effect on the mechanism and causes it to overheat.
• Charge units at their optimal temperature. Not all models tolerate sub-zero temperatures well, so for effective charging, maintain the correct temperature conditions. Once you have decided to buy an energy storage device, determine its installation location: away from direct rays of the Sun and away from open sources of fire.
• Never use a battery if it is: swollen, cracked, overheated, dropped from a height or mechanically damaged. Using a broken unit is hazardous to health and the environment.

Having decided to buy lithium batteries in Kyiv and other cities, you should find out how to properly store the battery. If you do not plan to use the unit for a while, store it at 50% charge. Air temperature also matters. The higher it is, the faster the device loses charge, so a cool room with zero or moderate positive temperatures is suitable for storage.
