Solinved

Sustainable energy use is becoming increasingly widespread with solar energy, electric vehicles, and energy storage systems. Lithium batteries are a key component of these systems. Lithium batteries are revolutionizing energy storage solutions with their high energy density, long lifespan, and low maintenance requirements. Solinved is pioneering domestic and reliable lithium battery production in Turkey with the launch of a demonstration production line at its new facility in the Polatlı Çekirdeksiz Organized Industrial Zone in Ankara.

What is a Lithium Battery?

Lithium batteries are rechargeable batteries known for their high energy density and lightweight construction. They are used to store energy in solar energy systems, electric vehicles, and industrial storage systems.

The main advantages of lithium batteries are:

• Long lifespan (typically 10–15 years)
• High charge/discharge cycles
• Low maintenance requirements
• Lightweight and compact structure
• High efficiency and energy storage capacity

How is Lithium Battery Production Done?

Lithium battery production is a process that requires advanced technology and high precision. The basic steps are as follows:

1. Material Preparation

Lithium battery production begins with the preparation of raw materials such as lithium, cobalt, nickel, and graphite. These materials form the battery's cathode and anode structures. Solinved maximizes battery performance by using high-quality raw materials.

2. Electrode Production

Cathode and Anode Coating: Materials containing lithium, nickel, or cobalt are coated onto the electrode surfaces.

Drying and Pressing: The coated electrodes are dried and pressed to increase their density. This process increases the battery's energy density and lifespan.

3. Cell Assembly

Electrode and Separator Assembly: The cathode and anode are assembled using special separators.

Cell Encapsulation: The cell is placed in a special coating and enclosure to prevent leakage and ensure safe operation.

4. Electrolyte Filling and Activation

Electrolyte Addition: Electrolyte is added to the cell to facilitate ion transfer.

Formation Process: Performance tests are performed by subjecting the battery to a charge/discharge cycle. This step determines the battery's capacity and efficiency.

5. Testing and Quality Control

Solinved lithium batteries undergo rigorous quality control tests after production:

• Capacity testing
• Internal resistance and energy efficiency testing
• Temperature and safety testing
• These stages ensure the batteries are long-lasting, safe, and high-performance.

Uses of Lithium Batteries

Lithium batteries are used in a wide variety of energy systems:

Solar Energy Systems:
By storing energy from solar panels, they enable energy use even at night or on cloudy days.

Electric Vehicles (EVs):
Lithium batteries enable electric vehicles to be lightweight and have long ranges. Solinved offers integrated solutions with EV charging systems.

Agricultural Irrigation Systems:
Lithium batteries can be used in irrigation pumps to provide energy independence, enabling uninterrupted irrigation.
