Lithium-ion batteries are widely used in home energy storage systems because of the advantages of lithium-ion batteries, such as long service life and taking up less space. In the future development of lithium-ion batteries, lithium-ion batteries will continue to bring more convenience to home energy storage. Let’s explore the mysteries of lithium-ion batteries for home energy storage.
1. How can lithium-ion batteries be used for home energy storage?
Lithium-ion batteries can be used independently or in a solar energy storage system. When a lithium-ion battery is used independently, it can take power from the grid and provide power support to the homeowner in the event of a power outage. Stand-alone lithium-ion batteries can also reduce the cost of electricity and avoid paying peak rates. When electricity is cheaper, lithium-ion batteries can be charged using the grid. When electricity is more expensive, you can use the electricity in the battery.
When lithium-ion batteries are used in off-grid solar systems, the electricity generated from the solar panels can be stored in the lithium-ion batteries, avoiding wasted solar energy. You can then use the electricity in the lithium-ion battery to power your home when there is peak power usage or no sunlight.
2. Types of lithium-ion batteries that can be used for home energy storage
Nowadays, the main types of lithium-ion batteries used for home energy storage are lithium iron phosphate batteries and nickel-cobalt batteries.
Lithium iron phosphate battery is a kind of battery that uses lithium iron phosphate as the positive material and carbon as the negative material, which has larger energy density, long service life and good safety performance. No memory effect and other advantages, but the cost of lithium iron phosphate battery may be higher. For home energy storage, lithium iron phosphate battery is still a very good choice.
Nickel-cobalt batteries compared to lithium iron phosphate battery cost will be lower, it has a better cycle life and safety performance, but its energy density is relatively low, small energy storage system will be better, for large energy storage system, it is not recommended that you use this battery.
3. What is the price of lithium-ion batteries for home use?
Lithium-ion batteries for home use are cheaper than large industrial lithium-ion batteries, usually priced at $130/kwh, for example, a 10kwh lithium-ion battery costs $1,300. In the specific sale, the price of lithium-ion batteries may vary, you choose the brand of lithium-ion batteries, type and quantity of lithium-ion batteries will affect the price of lithium-ion batteries.
4. Advantages and disadvantages of lithium-ion batteries
Pros: Lithium-ion batteries have a house discharge depth of 99%, which is almost 100% discharge, meaning the energy your family stores in lithium-ion batteries is not wasted. General lithium-ion batteries can reach 6000 cycles, the service life can be more than 10 years. And lithium-ion batteries are maintenance-free, which reduces the hassle of using them.
Disadvantages: Because of the excellent performance of lithium-ion batteries, lithium-ion batteries are more expensive. And lithium-ion batteries are affected by the temperature of the environment, only in the working temperature of lithium-ion batteries, it shows its advantages. In addition, it is also necessary to prevent lithium-ion batteries in the charging process may occur overheating problems.
5. What should I pay attention to for lithium-ion batteries for home energy storage?
Avoid short circuit of lithium-ion battery: the lithium-ion battery should not be in contact with metal objects, especially the positive and negative terminals of the lithium-ion battery, because the metal may cause the battery to form a no-load circuit, making the lithium-ion battery short circuit.
Avoid pressure: lithium-ion batteries should be stored with enough space to prevent the lithium-ion battery due to extrusion resulting in damage to the internal materials.
Avoid high temperature: lithium-ion batteries at high temperatures will accelerate the oxidation of the electrode material inside the battery, but also affect the performance of lithium-ion batteries.
Timely replenishment of lithium-ion batteries: lithium-ion batteries may not be used for a long time in less electricity, but you can not check again when you need to use, when not using lithium-ion batteries, to regularly replenish lithium-ion batteries to prevent lithium-ion batteries from over-discharge.
6. How to recycle lithium-ion batteries for home energy storage?
When you send lithium-ion batteries to the recycling center, generally the recycling center will refurbish the lithium-ion batteries in good condition and make used batteries for sale again. Some lithium-ion batteries that cannot be refurbished will be recycled by the recycler by liquefying them or dissolving them in an acid solution to separate the metal elements in the lithium-ion batteries for use in the manufacture of batteries.
Although lithium-ion batteries can be recycled, you can also reuse these lithium-ion batteries for energy storage in other less stringent battery requirements in order to extend the life of lithium-ion batteries.
7. The future of lithium-ion batteries
Lithium-ion batteries, as a kind of high-performance energy storage battery, occupy an important position in the energy storage neighbourhood. It is not only limited to home energy storage, but also has a huge market in communication energy storage, data center energy storage and so on. With the continuous development of lithium-ion battery technology in order to meet the future requirements of energy storage, lithium-ion batteries will be more useful in the critical period of new energy.
Conclusion:
In the application of lithium-ion batteries in home energy storage, for many families to provide the convenience of lithium-ion batteries in the selection of lithium-ion batteries, it is more recommended that you choose lithium iron phosphate batteries, in order to provide you with more peace of mind with electricity.
