What Is The Difference Between A Lithium Battery And A Storage Battery?

- Sep 05, 2018 -


What is the difference between a lithium battery and a storage battery? When inquiring about lithium batteries, there are many articles related to lithium batteries. In these articles, Storage batteries appear quite frequently, and many people may think that the Storage battery in the article is a lithium battery. However, this idea is wrong. The energy storage battery mentioned in the article generally refers to a lead-acid battery, while the lithium battery generally refers to a lithium-ion battery. The raw materials of the two are very different and cannot be confused.

The lithium battery is different from Storage battery:

What is a lithium battery?

A "lithium battery" is a type of battery using a lithium metal or a lithium alloy as a negative electrode material and using a nonaqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M. S. Whittingham proposed and began researching lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very demanding on the environment. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream.


What is a storage battery?

A storage battery is a device that converts chemical energy directly into electrical energy. It is a rechargeable battery that is recharged by a reversible chemical reaction. It is usually a lead-acid battery, which is a kind of battery. , belongs to the secondary battery. Its working principle: the external electric energy is used to regenerate the internal active material during charging, and the electric energy is stored as chemical energy. When discharging, the chemical energy is converted into electric energy output again, such as the mobile phone battery commonly used in life.

The above introductions about lithium batteries and storage batteries are all from Baidu Encyclopedia. Although encyclopedia entries can be edited by everyone, lithium batteries and storage batteries are industrial words, and the authenticity is guaranteed. However, encyclopedic entries can only be used as a shallow reference. If you want to know more about lithium batteries or storage batteries, ask the relevant industry people to get more accurate information.

Since lithium batteries and storage batteries can often appear together, it means that the two have similarities, that is, the functions are roughly the same, both of which exist as power supply tools. However, in this article, we focus on the differences between the two, so we will not discuss this in common.

Let's talk about the difference between a lithium battery and a storage battery. The difference in performance between the two is the difference between the two. It is the difference in performance that allows lithium batteries to completely replace the status of lead-acid batteries in the current era.

Performance comparison between lithium battery and storage battery:

Temperature tolerance: common lithium battery operating temperature is -20-60 degrees Celsius, but generally lower than 0 °C lithium battery performance will be reduced, discharge capacity will be reduced accordingly, so lithium battery performance full operating temperature, is common 0~40°C. The lithium battery temperature required by some special environments varies, and some can even operate normally in the environment of hundreds of degrees Celsius.

The operating temperature of the storage battery is generally between 20 ° C and 25 ° C. When the temperature is lower than 15 ° C, the discharge capacity decreases. When the temperature is lowered by 1 ° C, the capacity decreases by 1%, and the temperature is too high (more than 30 ° C). It will be greatly shortened.

Cycle life: The number of cycles of a lithium battery is generally about 2000-3000 times, while the number of cycles of a Storage battery is about 300-500 times. The cycle life of a lithium battery is about five or six times that of a Storage battery.

Mass specific energy (WH/kg): The lithium battery is 100-150, and the storage battery is 30-50.

Volume specific mass (Wh/L): The lithium battery is 200-250, and the storage battery is 60-90.

Charge and discharge: Lithium battery has no memory effect; battery can be charged and discharged at any time, battery self-discharge is low, monthly self-discharge is less than 1%, battery can be stored for a long time; power is strong, fast charge and fast release, 20% can be filled 80% Above, you can put the electricity out in 15 minutes.

Storage battery has a memory effect, can not be charged at any time to discharge at any time; there is a serious self-discharge phenomenon, the battery is easy to scrap for a period of time; the discharge rate is small, can not discharge for a long time.

There is a big difference between lithium batteries and storage batteries. In terms of environmental protection, in this era of environmental protection, environmentally-friendly and efficient batteries can conform to the development trend of the times and can be widely used. In modern times, lithium battery applications are used in all aspects of our lives, such as mobile phone batteries, watch batteries, and power car batteries.

In these applications, lithium batteries come in a variety of shapes, sizes, and types. Among them, the lithium battery pack is a broad prospect in the development of lithium batteries. The energy storage lithium battery pack can be used in small computer rooms, weak room and other room division systems, communication base stations, indoor and outdoor airless stations, radio and television, troops, oil, etc. Site, etc. As can be seen from the application range of the lithium battery pack, the lithium battery pack has high adaptability to the environment, and is suitable for an unmanned site, saving manpower.

As mentioned earlier in the article, if you want to know more about lithium battery or battery related information, it is best to ask industry stakeholders to get more accurate and credible information.
