Na ion battery use the intercalation and extraction of ions in the positive and negative electrodes and the diffusion between the two electrodes as the basic principle of charge and discharge, and have the characteristics of high energy density, high rate and long cycle life.In terms of performance, it can meet the technical requirements of the energy storage system.

Ningde Times stated on the interactive platform that the company is committed to promoting the industrialization of sodium-ion batteries in 2023.

On July 29, 2021, Ningde Times released the first generation of sodium-ion batteries. The energy density of a single battery cell reached 160Wh/kg, which is currently the highest level in the world. Charge it for 15 minutes at room temperature, and the power can reach 80%. However, in a low-temperature environment of minus 20°C, there is still a discharge retention rate of more than 90%. Previously, Ningde Times stated that in terms of manufacturing process, sodium-ion batteries can be compatible with lithium-ion battery production equipment and processes, and the production line can be quickly switched to complete the rapid layout of production capacity.

According to relevant reports, in the first half of this year, CATL's global power battery installed capacity was 71GWh, ranking first for five consecutive years, and its market share reached 34.8%, a year-on-year increase of 6.2 percentage points. Ningde Times stated that its sales volume in the first half of the year exceeded 100GWh, and the second quarter increased compared with the first quarter.

Na ion battery have nearly flooded the rechargeable battery market. However, the lithium resources currently used in the preparation of lithium-ion batteries in my country mainly depend on imports, and the cost is relatively high. In contrast, sodium resources are widely distributed, the cost is low, and the high and low temperature performance of sodium-ion batteries is excellent, and the safety is more stable. Therefore, sodium-ion battery systems continue to receive attention

After 5 months, the average price of battery-grade lithium carbonate broke through 500,000 yuan/ton again. On September 13, relevant data showed that the price of battery-grade lithium carbonate rose by 2,600 yuan/ton in a single day, and the average price stood at 500,000 yuan/ton, an increase of nearly 8 times from the beginning of last year and nearly 80% from the beginning of this year.

Because of its low production cost and high safety performance, sodium-ion batteries have attracted widespread attention and strategic layout from academia and industry. Combined with the cost and energy density of Na-ion batteries, it has broad application prospects in low-speed vehicles, large-scale energy storage, and smart grids.

Driven by the global goal of net zero carbon emissions, the electrification transformation in the road transportation field is accelerating, and the global new energy vehicle industry is in a period of rapid growth, driving the rapid growth of demand for power batteries. By 2024, the installed capacity of the global power battery market is expected to increase from GWh Entering TWh, it will exceed 3TWh by 2030. Among them, the installed capacity of power batteries in China is expected to account for about 45% of the world.
