The first 100kWh sodium-ion battery energy storage equipment in Huabei Oilfield was officially put into operation, using Veken technology cells!

This energy storage equipment adopts the cloud platform system independently developed by Zhejiang Vast Sodium, which can realize centralized online management of tens of thousands or even hundreds of thousands of oilfield energy storage systems. At the same time, the cathode material of the sodium battery cell of this equipment uses a high-performance material independently developed by Vastel Sodium, which has the characteristics of high capacity, long life, low gas production, and low temperature resistance.

It is worth mentioning that this energy storage equipment is also equipped with sodium battery cells independently developed by Veken Technology, with an energy density of 140wh/ kg, cycle more than 6000 timesSodium electricity technology. Weike sodium batteries not only have the characteristics of high energy density, long life, high cycle, and high safety, but also perform well in the environment. Even in areas of minus 40°C, the capacity retention rate can still reach Nearly 85%.

From mid-November 2023 to the present, the 100kWh sodium-ion battery energy storage equipment has successfully passed the low temperature test of minus 18 degrees Celsius in Langfang area, and has supplied more than 7,000 kilowatt hours of power to oil wells. Among them, more than 5,000 kilowatt-hours of photovoltaic power generation and more than 2,000 kilowatt-hours of valley electricity are used, with the energy conversion efficiency exceeding 90%. During the test, the goals of "maximizing the consumption of new energy and green electricity" and "minimizing the cost of grid power" were achieved by switching between photovoltaic power generation and grid off-peak power.

According to Qidian Research Institute (SPIR), energy storage will be the application field with the highest proportion of sodium battery shipments in the future. By 2025, the overall shipments of sodium batteries will reach 23GWh. , shipments in the energy storage field will reach 13GWh, accounting for 56.5%. By 2030, the overall shipment volume of sodium batteries will reach 438GWh, and the shipment volume in the energy storage field will reach 280GWh, accounting for 63.9%.

Since sodium-ion batteries have the advantages of low cost, long life, and high safety, they can be highly adapted to the needs of energy storage application scenarios, and the potential market demand is huge. At the same time, the advantages of low temperature resistance and high current resistance allow energy storage systems equipped with sodium batteries to better adapt to extreme climates and can better adapt to remote areas and cold northern regions. environment.

In the future, sodium-ion batteries will become the best choice for the energy storage market! Weike Technology will give full play to the performance advantages of sodium electricity based on different application scenarios, explore and expand more new forms of sodium electricity, and help build a green and low-carbon economy.
