18650 vs. polymer lithium battery: Who will dominate the future electric vehicle market?


Against the backdrop of the rapid development of the electric vehicle industry, the choice of battery technology route has become a key factor in determining the competitiveness of enterprises. The technical competition between 18650 cylindrical lithium batteries and polymer lithium batteries is reshaping the market structure of electric vehicle power batteries.


1. Technical performance comparison

The 18650 battery has mature technology, good consistency, and obvious cost advantages. The energy density reaches 250Wh/kg, which supports long-range requirements. Polymer lithium batteries are flexible in design, customizable in shape, and have high space utilization.


The energy density is slightly higher than that of 18650 batteries, but the cost is higher. Both technologies are continuously improving, and the performance gap is gradually narrowing. These characteristics affect their application in the electric vehicle market.


2. Market application status

18650 batteries are widely used in Tesla and other models, with significant economies of scale. Polymer lithium batteries are gradually promoted in high-end models to meet personalized design needs.


The two technologies have their own advantages in different market segments. 18650 batteries dominate the mid- and low-end markets, while polymer lithium batteries are favored in the high-end market. This pattern reflects the diversity of market demand.


3. Future development trends

18650 batteries maintain cost advantages through material innovation and process improvement. Polymer lithium batteries break through the bottleneck of mass production and the cost gradually decreases. The two technical routes will coexist for a long time to meet different market needs.


New battery technologies such as solid-state batteries may change the competitive landscape. These trends indicate that the electric vehicle battery market will be more diversified.


18650 batteries and polymer lithium batteries each have their own advantages and will continue to play an important role in the future electric vehicle market. Enterprises need to choose the appropriate technical route based on product positioning, while maintaining technical openness to cope with new technological changes that may occur in the future. The continuous advancement of battery technology will provide a strong impetus for the development of the electric vehicle industry.
