The future development trend of new energy vehicle battery technology mainly includes the following aspects:

1. Performance improvement:

-Higher energy density: This is one of the key goals in the development of battery technology. Higher energy density enables electric vehicles to have a longer range with the same size and weight of the battery pack. For example, new battery technologies such as solid-state batteries and lithium-sulfur batteries theoretically have the potential for higher energy densities than current lithium-ion batteries. The energy density of solid-state batteries is expected to reach more than 500 watt-hours per kilogram in the future, and the theoretical energy density of lithium-sulfur batteries is as high as 2600 watt-hours/kg. With the deepening of the research on these new battery materials and the gradual maturity of the technology, the range of new energy vehicles will continue to improve, and even is expected to reach the level of traditional fuel vehicles.

-Faster charging speed: Fast charging technology is essential to improve user convenience. In the future, it is expected that the charging time of electric vehicles will be greatly shortened by improving battery materials, optimizing charging circuits and charging strategies. For example, the new fast charging technology may be able to charge the battery to 80% capacity in 10 - 15 minutes, or even a higher proportion of the charge in a shorter time.

-Longer battery life: Extending the cycle life of the battery can reduce the user's cost. The R & D team will continue to explore new electrode materials, improve battery structure design, and optimize battery management systems to improve battery cycle life. In the future, new energy vehicle batteries are expected to reach 5000 - 10000 cycles or even higher, meeting the needs of long-term use of vehicles.

-Better safety: The safety of batteries has always been an important concern in the development of new energy vehicles. Future battery technology will further improve battery safety by adopting safer battery materials, optimizing battery structure, and improving battery management systems. For example, due to the use of solid electrolytes, solid-state batteries have higher safety than traditional liquid lithium-ion batteries, and can effectively reduce the risk of battery thermal runaway.

2. Technological innovation:

-Commercialization of solid-state battery technology: Solid-state batteries are an important development direction of battery technology for new energy vehicles in the future. Solid-state batteries have the advantages of high energy density, good safety and long cycle life, and have made some progress in research. It is expected that in the next few years, solid-state battery technology will gradually realize commercial application, which will further improve the performance and competitiveness of new energy vehicles.

-Research and development of new battery materials: In addition to solid-state batteries and lithium-sulfur batteries, researchers are constantly exploring other new battery materials, such as lithium-air batteries and sodium-ion batteries. These new battery materials have their own advantages and potentials. For example, the raw materials of sodium ion batteries are abundant, the cost is low, and the theoretical energy density of lithium-air batteries is extremely high. In the future, as the research on these new battery materials continues to deepen, it may bring new breakthroughs in new energy vehicle battery technology.

-Intelligent battery management system: The intelligent battery management system can monitor the status of the battery in real time, including voltage, current, temperature, SOC(State of Charge, battery state of charge) and other parameters, and charge and discharge the battery according to these parameters Process for precise control and management. The future battery management system will be more intelligent, able to predict and evaluate the performance and health of the battery through big data analysis, artificial intelligence and other technologies, identify potential problems in advance and take corresponding measures to improve the reliability and safety of the battery.

3. Cost reduction:

-Large-scale production: With the continuous expansion of the new energy vehicle market, the production scale of batteries will also continue to increase. Large-scale production can reduce the production cost of batteries, improve production efficiency and product quality. At the same time, the synergy effect of the industrial chain will further reduce the raw material procurement cost and production equipment cost of the battery.

-Process improvement and technology upgrade: Continuously improve the production process and technology of the battery, improve the production efficiency and yield of the battery, reduce the loss and waste in the production process, thereby reducing the production cost of the battery. For example, the use of more advanced electrode preparation technology, battery assembly technology, etc., can improve the performance and quality of the battery, while reducing costs.

-Substitution and recycling of raw materials: On the one hand, look for low-cost and stable supply of raw materials to replace existing expensive raw materials, such as the development of cobalt-free or low-cobalt lithium-ion battery cathode materials; on the other hand, strengthen battery recycling and Reuse technology, extract useful materials from used batteries, reduce the demand for raw materials, thereby reducing battery production costs.

4. Environmentally sustainable:

-Improve the recycling rate of batteries: With the popularization of new energy vehicles, the number of used batteries will continue to increase. Improving the recycling rate of batteries can not only reduce environmental pollution, but also reduce the demand for raw materials and save resources. In the future, a more complete battery recycling system will be established to improve the efficiency and technical level of battery recycling and realize the full life cycle management of batteries.

-Use sustainable materials: In the production process of batteries, use renewable and degradable materials as much as possible to reduce the impact on the environment. For example, the use of bio-based materials to prepare the separator, shell and other components of the battery can not only reduce costs, but also improve the environmental performance of the battery.

5. Diversified applications:

-Expanding application areas: New energy vehicle battery technology will not only be applied to the field of electric vehicles, but will also be extended to other fields, such as energy storage systems, electric ships, and electric aircraft. The development of these areas will provide a broader market space and development opportunities for new energy vehicle battery technology.

-Integration with smart grid: future new energy vehicles will be deeply integrated with smart grid. Through vehicle to grid (V2G) technology, electric vehicles can feed back the electric energy in the battery to the grid when not in use, realizing the two-way flow of electric energy. This can not only improve the stability and reliability of the power grid, but also bring certain economic benefits to users.
