Current status of lithium iron batteries

For a variety of advantages, lithium -iron batteries are often called the third -generation battery after carbon -based battery and alkaline battery, but in fact, there is no obvious trend of substituing alkaline batteries. The cost and price are restricted by development.

For the reasons for the high price of domestic lithium -iron batteries, manufacturers have made special analysis, which are roughly summarized into the following aspects:

1. High -priced raw materials and the special production environment and safety requirements brought by it: The first reason for the high -priced result of lithium iron batteries is to use metal lithium belts as negative poles, which is much higher than the zinc cream of alkaline batteries; metal lithium is an active element, which is an active element. Therefore, there are higher requirements for the temperature and humidity in the production environment. Not only must the dryer and air -conditioning equipment be installed, but also the staff in the post should be increased. The active negative metal lithium of the lithium -iron battery, plus the electrolytic liquid is volatile, and the positive and septum is combustible. These need to be added to control the corresponding equipment, and these devices are not in the production of carbon batteries and alkaline batteries.

2. Strong external dependence: The equipment must be imported. Due to the fewer equipment manufacturers, foreign equipment vendors can ask for price, and the equipment must be asked to help them. During the maintenance process, high -priced import equipment parts and high payment of maintenance are required. fee. At the same time, electrolytes actually rely on imports, and their composition and formula are the business secrets of manufacturers.

3. Losses in production, especially the high waste rate: Due to the high accuracy requirements of lithium iron batteries, it is stricter for raw materials selection and manual operation. The materials are charged and unqualified raw materials, or artificial misunderstanding can cause the waste rate to appear or improve.

It is the above -mentioned internal and external reasons that the price of lithium iron batteries is difficult to reduce. On the other hand, since 2006, the state stipulates environmental protection standards for carbon -based batteries and alkaline batteries, and existing alkaline batteries have achieved mercury -free, which has caused lithium iron batteries to replace alkaline batteries.
