Pourquoi une bonne batterie solaire est essentielle pour le stockage de l'énergie

Nowadays, global climate change and energy crisis are quite a headache, so the utilization of renewable energy is particularly critical. Solar energy, clean, inexhaustible, everywhere, is slowly turning into a major contributor to the energy transition. Speaking of which, a good solar battery, that is an important tool to capture these solar energy, its performance, high efficiency, reliable or not, directly affects the solar power system is good, cost-effective or not. Next, let’s talk about good solar battery.

What is Solar Battery

A solar cell is a thin photovoltaic semiconductor that generates electricity directly from sunlight. It is also called a “solar chip” or “photovoltaic cell”. Simply put, as long as it is illuminated by light, under certain conditions of illumination, it can instantly output voltage, and if there is a circuit, it can also generate current.

The principle of power generation is actually the photovoltaic effect, which is the phenomenon of electric potential generated by the absorption of light energy by a substance. Solar cells are based on this principle, the light energy directly into electrical energy devices. It has a core component, is the PN junction, when the sunlight irradiation to the semiconductor surface, the semiconductor inside the electron and hole will be excited, and then in the PN junction under the action of the separation, the electron is pushed to the N area, the hole is pushed to the P area, so that in the PN junction on both sides of the potential difference, that is, the voltage. If a load is connected externally, a circuit can be formed and a current can be output.

The efficiency of a good solar battery has to be high, and it has to convert more light energy so as to guarantee the overall performance and economic benefits of the power generation system. Moreover, it must be stable and reliable, and withstand the test of various environments.

Types of Solar Batteries

There are really many types of solar cells, each with their own characteristics. Let’s talk about a few common ones today. For example, lithium iron phosphate batteries, which are commonly used in safe residential solar systems; there are also lead-acid batteries, which are also very common; and then there are lithium solar cells.

Li-iron phosphate batteries (LiFePO4 solar cells)

LiFePO4 battery, or lithium iron phosphate battery, is a lithium-ion battery that uses lithium iron phosphate as the cathode material and carbon as the anode material. It usually has a single unit rated voltage of 3.2V and a charge cut-off voltage between 3.6V and 3.65V. When considering the integration of renewable energy sources, a good solar battery paired with LiFePO4 technology can provide efficient storage solutions for solar power systems.

The operating principle of lithium iron phosphate batteries mainly involves the process of embedding and dislodging lithium ions between the positive and negative electrodes. During charging, lithium ions are dislodged from the lithium iron phosphate at the positive electrode and embedded in the graphite at the negative electrode through the electrolyte, while electrons are transferred from the positive electrode to the negative electrode through an external circuit to store electrical energy. During discharge, lithium ions are removed from the graphite at the negative electrode and return to the lithium iron phosphate at the positive electrode through the electrolyte, while electrons are transferred from the negative electrode back to the positive electrode through an external circuit, releasing electrical energy. A good solar battery designed with LiFePO4 can ensure reliable performance in such systems, providing long-term energy storage solutions.

Lithium iron phosphate batteries have high thermal stability, even at high temperatures or overcharging is not easy to thermal runaway, so the safety is high. Moreover, it has excellent cycle stability and can withstand a large number of charging and discharging cycles while maintaining a high capacity. Plus, it is suitable for working in high temperature environments with stable performance. A good solar battery based on this technology offers efficient storage capacity and reliability for solar energy systems, ensuring sustained energy usage over time. Finally, lithium iron phosphate battery does not contain heavy metals and other harmful substances, making it environmentally friendly.

Because of its many advantages, lithium iron phosphate battery is widely used in many fields. For example, electric vehicles, portable electronic devices, energy storage systems, and drones, as well as in renewable energy applications with good solar batteries, further boosting the clean energy transition.

Lead-acid battery is a kind of storage battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a kind of storage battery of sulfuric acid solution. This battery discharge state, the main component of the positive electrode is lead dioxide, the main component of the negative electrode is lead; charge state, the main component of the positive and negative electrodes are lead sulfate. Lead-acid batteries are mainly divided into two types: open lead-acid batteries and sealed maintenance-free lead-acid batteries.

The working principle of lead-acid battery is mainly the mutual conversion of chemical energy and electric energy. During the discharge process, the lead at the negative electrode reacts with the sulfuric acid in the electrolyte to generate lead sulfate and release electrons, which flow to the positive electrode through the external circuit to form an electric current. At the same time, the lead dioxide at the positive electrode also reacts with the sulfuric acid in the electrolyte and the electrons flowing from the negative electrode to form lead sulfate. This process converts chemical energy into electrical energy. During charging, this process is reversed, and the lead sulfate decomposes to form lead, lead dioxide, and sulfuric acid under the action of the electric current, and the electrical energy is converted to chemical energy and stored. A good solar battery can benefit from lead-acid technology for solar energy storage, providing reliable power for renewable energy systems.

Lead-acid batteries are stable, inexpensive, and can be used repeatedly, and have a high safety capacity. It is used in automobile, electric power, communication, UPS power supply, and railroad, ship and these fields. Moreover, it is also suitable for storing renewable energy sources like solar and wind. Speaking of good solar batteries, if you use lead-acid technology, you can store solar energy and use it later, which is practical and saves money.

However, lead-acid batteries also have some disadvantages. For example, it has a relatively low energy density and large weight and volume, which makes it less suitable for some applications that require high energy density and lightweight. In addition, lead-acid batteries have certain environmental pollution problems because they contain hazardous substances such as heavy metals lead and sulfuric acid, which may pollute the environment if not handled properly. Therefore, when using and disposing of lead-acid batteries, it is necessary to strictly follow the relevant environmental regulations and operating procedures. Still, a good solar battery designed with proper safety and disposal guidelines can mitigate these concerns, offering a practical solution for solar energy storage.

Lithium-ion cells

Lithium-ion batteries (abbreviated as LIBs) are secondary batteries that use lithium metal or lithium alloy as the anode material and a non-aqueous electrolyte solution as the electrolyte. It mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During the charging and discharging process, lithium ions migrate back and forth between the positive and negative electrodes, thus realizing the storage and release of electrical energy. A good solar battery utilizing lithium-ion technology can efficiently store energy generated from solar systems for later use.

The working principle of lithium-ion batteries is based on the movement of lithium ions between the positive and negative electrodes. During the charging process, lithium ions are de-embedded from the positive electrode material and move through the electrolyte to be embedded in the negative electrode material. The discharge process is reversed, with lithium ions de-embedding from the negative electrode and returning to the positive electrode material through the electrolyte. This process is accompanied by the flow of electrons in an external circuit, which generates an electric current. In renewable energy systems, a good solar battery based on lithium-ion technology can store solar power efficiently and reliably.

A lithium-ion battery typically consists of a positive electrode, a negative electrode, and an electrolyte and diaphragm in between. The cathode material is usually a lithium compound, such as lithium manganate, lithium iron phosphate, and lithium nickelate. The negative electrode material is usually graphite or other carbon materials. The electrolyte is usually formed by dissolving lithium salts in an organic solvent, and the diaphragm is used to isolate the positive and negative electrodes to prevent short circuits. Using good solar battery solutions with lithium-ion technology enhances the efficiency of solar energy storage systems.

Because lithium-ion batteries have the advantages of high energy density, long life, good low-temperature performance, and environmental protection and non-pollution, they are widely used in various fields. For example, in portable electronic devices, lithium-ion batteries power devices such as laptops, tablet PCs, handheld games, and smartphones. In addition, in the field of electric vehicles, lithium-ion batteries, as one of the main types of power batteries, are widely used in micro-hybrids, hybrids, plug-in hybrid electric vehicles, pure electric vehicles, and so on. In industrial applications, lithium-ion batteries are also used in various forms of robotics as well as in special applications (e.g., marine and maritime applications, aerospace applications), and so on. In addition, lithium-ion batteries are used in battery energy storage systems (BESS), covering a wide range of application scenarios from stationary high-capacity energy storage systems, community energy storage systems, household energy storage systems, and emergency power UPS. A good solar battery can further enhance the effectiveness of these applications by providing stable and efficient solar energy storage.

Lithium-ion batteries have the advantages of high energy density, long cycle life, good low-temperature performance, and environmental protection without pollution. However, lithium-ion batteries also have shortcomings such as higher cost, safety issues, and capacity degradation.
