What are the advantages and disadvantages of power batteries and energy storage batteries?-(1)

Energy storage mainly refers to the storage of electrical energy. Energy storage is a term in petroleum reservoirs and represents the ability of reservoirs to store oil and gas. Energy storage itself is not an emerging technology, but it has just emerged from an industrial perspective and is in its infancy.
So far, China has not reached the level that the United States and Japan regard stored energy storage as an independent industry and introduce specific support policies. Especially in the absence of a mechanism for energy storage, the commercialization model of the energy storage industry has not yet formed. .
Lead Acid Batteries are generally used for high-power storage of Maintenance Free Battery, mainly used for emergency power supply, battery vehicles, and storage of surplus energy in power plants. Rechargeable dry batteries can also be used in low-power applications: nickel-metal hydride batteries, Lithium Batteries, etc. This article follows the small series to understand the advantages and disadvantages of the nine battery storage.
Advantages and disadvantages of battery energy storage (analysis of nine energy storage batteries)

First, Lead acid battery
The main advantage:
1. The raw materials are easy to obtain and the price is relatively low;
2. High rate discharge performance is good;
3, good temperature performance, can work in the environment of -40 ~ +60 ° C;
4, suitable for floating charge use, long service life, no memory effect;
5. The used batteries are easy to recycle, which is conducive to environmental protection.
Main disadvantages:
1, the specific energy is low, generally 30 ~ 40Wh / kg;
2, the service life is not as good as Cd/Ni battery;
3, the manufacturing process is easy to pollute the environment, must be equipped with three waste treatment equipment.

Second, nickel-hydrogen battery
The main advantage:
1. Compared with lead-acid batteries, the energy density is greatly improved, the weight energy density is 65Wh/kg, and the volumetric energy density is increased by 200Wh/L;
2. High power density, high current charge and discharge;
3. Good low temperature discharge characteristics;
4, cycle life (up to 1000 times);
5. Environmental protection and no pollution;
6. Technical comparison Lithium-ion battery is mature.
Main disadvantages:
1. The normal working temperature range is -15~40°C, and the high temperature performance is poor;
2, the working voltage is low, the working voltage range is 1.0 ~ 1.4V;
3, the price is more expensive than lead-acid batteries, nickel-metal hydride batteries, but the performance is worse than lithium-ion batteries.

Third, lithium ion battery
The main advantage:
1. Higher specific energy;
2. The voltage platform is high;
3, good cycle performance;
4, no memory effect;

5, environmental protection, no pollution; currently is one of the best potential electric vehicle power battery.
