Energy storage batteries mainly refer to batteries used in solar power generation equipment and wind power equipment and renewable energy savings energy. The performance of the battery storage power storage directly affects the capacity, safety and durability of the energy storage system. So, what are the types of energy storage batteries? What are the advantages and disadvantages of commonly used Residential Energy Storage System batteries? Let's take a look at it together.

Energy storage can be divided into mechanical energy storage and chemical energy storage. Electrochemical energy storage refers to various secondary battery energy storage. It uses chemical elements to make energy storage media, and the charging and discharge process accompanied by chemical reactions or changes in the energy storage medium. It mainly includes lead -acid batteries, liquid flow batteries, sulfur sulfur batteries, lithium ion batteries, etc.

1. Lithium ion battery

Lithium batteries are a class of lithium metal or lithium alloy as negative electrode materials and use non -hydrolytic solutions. Because the chemical characteristics of lithium metal are very lively, the processing, preservation and use of lithium metal are very high. With the development of science and technology, now lithium 

The battery has become the mainstream.

The main advantages of lithium -ion batteries are: long service life, high storage energy density, light weight, and strong adaptability; the disadvantage is poor safety, explosion, high cost, and limited use conditions.

2. Tricss lithium battery

The ternary polymer lithium battery refers to the lithium battery that uses nickel cobalt lithium manganate (Li (NICOMN) O2) Totic electrode material. The ternary composite positive material is based on nickel salt, cobalt salt, manganese salt as the raw material, which contains inside The proportion of nickel cobalt manganese can be adjusted according to actual needs. The three -yuan material for a positive battery is high than the lithium cobaltate battery, but the voltage is too low. Feeling of insufficient capacity.

The main advantages of ternary lithium batteries are: high energy density, small volume of the same capacity. The disadvantage is: poor thermal stability, short -circuit internal short circuit, easy to produce bright fire, fast capacity attenuation, and short life.

3. Lead -threate battery

It is a type of electrode mainly made of lead and its oxides. The electrolyte is a battery of sulfate solution. In the discharge state of lead -acid batteries, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charging state, the main component of the positive and negative electrode is lead sulfate.

The advantages of lead -acid batteries are: safety sealing, discouraged system, simple maintenance, long service life, stable quality, and high reliability; the disadvantage is that the lead's pollution is large and the energy density is low (that is, too bulky).

4. Lithium iron phosphate battery

Lithium iron phosphate batteries refer to lithium ion batteries using lithium iron phosphate as a positive electrode material. Lithium ion batteries are mainly lithium cobaltate, lithium manganate, lithium nickel, and ternary materials, lithium iron phosphate, etc. Among them, lithium cobaltate is currently the positive electrode material used by most lithium -ion batteries.

The main advantages of lithium iron phosphate batteries are: excellent charging and discharge performance, no memory effect, long life, good high temperature resistance, good safety performance, and environmental protection; disadvantages are: low energy density, large volume of the same capacity, low temperature performance slightly reduced slightly reduced performance The cost of manufacturing is higher.
