Sodium battery is a kind of secondary battery (rechargeable battery), which mainly depends on the movement of sodium ions between the positive and negative electrodes, which is similar to the working principle of lithium battery.
Compared with other secondary batteries, sodium battery has obvious advantages in cost, safety, rate performance and charging time, and has stronger comprehensive cost performance: 1) the BOM cost of sodium battery is 30% - 40% lower than that of lithium iron phosphate battery; 2) The internal resistance of sodium battery is higher than that of lithium battery. In the case of short circuit, the instantaneous heating capacity is less, and the temperature of thermal runaway is higher than that of lithium battery, which has higher safety; 3) Sodium battery has good rate performance and can adapt to responsive energy storage and large-scale power supply; 4) In terms of fast charging capacity, the charging time of sodium battery only takes about 10 minutes, while that of lithium iron phosphate battery takes more than 45 minutes.
However, sodium battery products also have some disadvantages in terms of energy density and cycle life: 1) in terms of energy density, at present, the energy density of sodium battery cell is between 100-160wh / kg, which is weaker than lithium battery but stronger than lead-acid battery; 2) In terms of cycle life, sodium battery can realize cycle charge and discharge for about 3000 times, which can only reach about half of the cycle life of lithium iron phosphate battery.
According to the "sodium battery Market Research Report" released by CMRC Zhongyan Century Consulting, under the condition of the shortage of lithium resources and the gradual rise of lithium battery manufacturing cost, sodium battery, as one of the important technical routes of secondary battery, its production process and technical development have been relatively mature. At the same time, with its resource and cost advantages, sodium batteries are expected to take the lead in replacing lithium iron phosphate batteries and lead-acid batteries in areas such as energy storage and low-speed electric vehicles with low requirements for energy density and strong cost sensitivity in the future, and there is also sufficient downstream demand. According to the development experience of lithium iron phosphate battery industry, it is expected that by 2025, the market penetration rate of sodium battery in the field of energy storage and low-speed vehicles will reach about 15%, and the permeable market scale is expected to reach 12.24 billion yuan, with broad potential market prospects in the future.
With the research of sodium battery technology becoming more and more mature, and the layout of leading enterprises represented by zhongkehai sodium and Ningde era, it will promote the rapid establishment of sodium battery industry chain ecology and increasingly fierce market competition. It is expected that the large-scale industrialization of sodium battery will also be faster and faster(source: Zhongyan Century Market Research Co., Ltd. the opinions in this article are for reference only and are not used as investment suggestions!)
