CR2450 battery

Development direction of CR2450 battery energy storage technology

It is understood that the main advantages of vanadium batteries are deep high current density discharge, long cycle life, fast charging, and low price compared to other energy storage devices. Vanadium batteries are very suitable for large-scale static energy storage. However, vanadium batteries also have disadvantages, such as low energy density, large volume, and slightly higher cost of large-scale energy storage applications. Although each energy storage technology has its advantages and disadvantages, in the foreseeable future, there will inevitably be a situation where sodium sulfur batteries, vanadium batteries, lithium batteries and other technologies coexist in the energy storage field, competing with each other, and there is no situation where one technology monopolizes the entire market.

At present, there is a consensus on vanadium batteries at the government level, the industry and the academic community that vanadium batteries are most suitable for China's development. First of all, China is rich in vanadium ore resources and has core technologies. Through cross-border integration, Chinese companies have mastered the world's key vanadium CR2450 battery technologies. The characteristics of vanadium batteries are also suitable for the needs of China's power grid, with long life, repeated discharge and high reliability, which can fully meet China's needs for building smart grids.

The comprehensive development and application of peak-shaving energy storage batteries will greatly improve the operating efficiency of the power system. Thermal power has poor peak-shaving capacity in power generation. Although my country has implemented time-of-use electricity prices, the difference in peak and valley power generation is still large. Solving the problem of power peak-shaving is a global issue. Vanadium batteries are a major revolution in energy storage technology and are expected to break through the bottleneck of the development of the new energy industry.

"Recently, my country has continuously increased its attention to and policy support for the field of environmental protection and low carbon. In the foreseeable future, there will be more and more pure electric vehicles. Even with the current market size, the power CR2450 battery of vehicles is already a huge market. However, it is well known that the country pays attention to the environmental protection of lead-acid batteries. The Yangtze River Delta region has successively closed more than 500 large and small lead-acid CR2450 battery manufacturers. According to the planning of relevant departments, 3,000 lead-acid CR2450 battery companies across the country will be closed and integrated into 300 large lead-acid CR2450 battery companies, and other small ones that do not meet environmental protection standards will be reorganized and merged. These are development bottlenecks directly facing the CR2450 battery industry and the electric vehicle industry. How to solve the demand for these batteries and how to transfer production capacity are all issues worthy of consideration by industry peers." In the face of the development of my country's CR2450 battery enterprises, Huang Youquan believes that "on the one hand, it may be replaced by lithium batteries, but according to the forecast of government agencies, lithium batteries can only replace 5-10% of the market share of lead-acid batteries. Even if capacitors are included, most of the rest is still unsettled. Moreover, lithium batteries also have stability and safety issues, while the biggest problem of lead-acid batteries is environmental protection."

It is understood that the current solid electrolyte vanadium power CR2450 battery has already approached the level of lithium batteries in terms of power, charge and discharge, specific energy, etc., and has relative advantages over lithium batteries and lead-acid batteries in terms of safety, service life and cost. At present, China produces 130 million KVAH of lead-acid batteries annually, and a total of 68 million KVAH was produced from January to June 2011. If calculated based on 12V/120AH automotive batteries, the annual output is about 90 million. China's production accounts for 50% of the world. In 2010, the global sales of lead-acid batteries were about 66 billion US dollars.

According to the CR2450 battery industry data in recent years, the market for lead-acid batteries, electric vehicle batteries, and electric vehicle batteries is about 300 billion yuan. The market size of wind power energy storage equipment and urban peak-shaving energy storage equipment used in large vanadium CR2450 battery stacks will be around 1.1 trillion yuan. This is the historical opportunity that the general trend of national economic development has brought to the vanadium CR2450 battery industry.
