Industry estimates suggest that by 2030, the sales of electric vehicles in Europe could reach 9.5 million, with an electric vehicle penetration rate of 60%. Many automakers are now considering LiFePO4 batteries for their electric vehicles due to various reasons. For example, in 2021, Tesla started widely using LiFePO4 technology batteries, especially in its Shanghai factory. Other automakers such as Ford, Rivian, Fisker, and General Motors in the US, as well as many European automakers like Renault, Stellantis, Volkswagen, and Hyundai have also indicated their intention to use LiFePO4 batteries.
- Cost Considerations in the Automotive Industry: The cost of batteries is a significant factor in the automotive industry. LiFePO4 batteries offer a cost-effective solution compared to NCM batteries. The price difference between LiFePO4 and NCM batteries can be substantial. For example, as of June 2024, the average price of vehicle-mounted LiFePO4 batteries in the domestic market was 380 yuan/kWh, while the average price of vehicle-mounted high-nickel NCM batteries was 550 yuan/kWh. This cost difference can translate into a significant price advantage for electric vehicles equipped with LiFePO4 batteries.
3.2 Energy Storage Sector
- Growth of the Energy Storage Market: The energy storage market in Europe is experiencing rapid growth. After the 2021 energy crisis, the European energy storage market has been developing at a high speed. The increase in renewable energy generation, such as wind and solar, has led to a greater need for energy storage to balance the grid. In 2023, the share of renewable electricity in the EU reached 44%, and the growth of wind and solar power generation accounted for a significant portion of this increase. As the proportion of fluctuating renewable energy generation increases, more energy storage is required to ensure grid stability.
- Advantages of LiFePO4 in Energy Storage: LiFePO4 batteries have several advantages for energy storage applications. Their high safety and long cycling life make them suitable for large-scale energy storage systems. For example, compared to NCM batteries, LiFePO4 batteries have a higher thermal runaway temperature and do not produce oxygen during thermal runaway, which reduces the risk of fire and explosion. In addition, LiFePO4 batteries have shown good performance in long-term cycling tests, which is crucial for energy storage applications that require frequent charging and discharging.
Another advantage is the relatively stable performance of LiFePO4 batteries under different environmental conditions. They can maintain a relatively consistent output voltage and capacity, which is beneficial for the efficient operation of energy storage systems. This stability also contributes to the reliability of the grid when using LiFePO4 batteries for energy storage.
Moreover, the cost-effectiveness of LiFePO4 batteries in the long term is an important factor. Although the initial investment may be comparable to some other battery technologies, the lower degradation rate and longer lifespan mean that the overall cost per unit of energy stored over the lifetime of the battery is often lower. This makes LiFePO4 batteries an attractive option for energy storage projects with a long-term perspective.
In terms of scalability, LiFePO4 battery systems can be easily scaled up or down depending on the specific requirements of the energy storage application. This flexibility allows for customized solutions for different grid sizes and energy storage needs, whether it is for small-scale residential energy storage or large-scale utility grid storage.
