12V Cylindrical Sodium ion Battery Cell for Solar Street Light Energy Storage System
During the day, the solar photovoltaic panels of street lamps absorb sunlight and convert it into electrical energy, which is stored in sodium ion batteries and used for lighting at night. The entire system is light controlled induction, automatically turning on and off around 6pm and 6am respectively, with a night lighting time of over 12 hours. This sodium ion battery street lamp has been installed for 4 months, during which there have been low temperatures, heavy snowfall, and strong winds and cold waves. However, the lighting duration, brightness, and safety of the sodium ion battery street lamp have not been affected at all.
At 3 pm, the location of the sodium ion battery solar street light was obstructed by surrounding buildings, which affected the sunlight. Even with scattered light, the duration of street lighting will not be shortened. Next, we will conduct in-depth testing of sodium ion battery solar street lights and actively promote their application in the market.
Energy storage system: Sodium ion batteries have potential advantages for large-scale energy storage systems. Due to its high safety and low raw material cost, sodium ion batteries have broad application prospects in the field of energy storage. Especially in the field of renewable energy such as wind power and solar power, sodium ion batteries are expected to become an ideal energy storage system solution.
Technical advantages of sodium ion batteries
Abundant resources: Sodium is one of the abundant elements in the Earth's crust, with much higher reserves and distribution than lithium, and is not affected by geopolitics or resource shortages, thus having significant cost advantages. The mining and extraction cost of sodium ions is low, the supply chain stability is high, and it is not easily affected by market fluctuations.
Cost advantage: The cost of sodium ion batteries is lower than that of lithium-ion batteries, especially in terms of positive and negative electrode materials. Sodium ion batteries usually use low-cost materials such as sodium manganese oxide or hard carbon, which are more economical than materials such as lithium cobalt oxide and nickel cobalt manganese oxide in lithium-ion batteries.
Higher safety: Sodium ion batteries have high thermal stability, high thermal runaway temperature, and more stable performance under high temperature and overcharge conditions. Therefore, sodium ion batteries have certain safety advantages in energy storage and large-scale battery pack applications, which are conducive to reducing the risk of explosions and fires.
Superior low-temperature performance: Compared to lithium-ion batteries, sodium ion batteries have less performance degradation in low-temperature environments and are suitable for application scenarios in cold regions. The improvement of low-temperature performance gives it unique advantages in applications such as energy storage systems and outdoor equipment in high latitude regions.
