Despite the rise of new battery technologies, lithium iron phosphate (LFP) batteries remain the most widely used solution in power batteries and large-scale energy storage. This is mainly due to their high safety, long cycle life, and well-controlled costs. At this year’s exhibition, LFP technology showed strong innovation in three main areas: material improvement, cell structure design, and large-capacity energy storage products. These advances continue to push performance limits and strengthen market competitiveness.
More refined material processing
Many material suppliers showcased improvements such as carbon coating, particle structure redesign, and crystal structure optimization. These methods help increase material density and improve lithium-ion movement. Several new high-density LFP materials were introduced, allowing higher energy density without increasing cell size or reducing lifespan, while still keeping costs and operating stability under control. These products are well suited for mainstream passenger vehicles.
Ongoing innovation in cell and pack structure
Blade batteries, large cylindrical cells, and CTP (cell-to-pack) designs have gone through multiple upgrades. By reducing unnecessary internal structures and making better use of space, overall battery system range has improved significantly. This allows LFP batteries to move into mid- and high-end long-range vehicles, breaking their past limitation to low-end transportation markets.
Mass production of ultra-large energy storage cells
Many large-format energy storage cells with capacities of several hundred ampere-hours were displayed. These products commonly achieve over 10,000 charge cycles. Designed for long-duration energy storage stations, commercial and industrial storage, grid load balancing, and power supply in remote areas, they offer much higher reliability in real-world operation and are becoming a key foundation for large-scale energy storage growth.
Overall, LFP batteries cover a wide range of applications and have very mature mass-production capabilities. In the short to medium term, they will continue to be the industry’s backbone, holding strong positions in passenger vehicles, commercial vehicles, and large energy storage systems.
2.2 Sodium-Ion Batteries Accelerate Commercial Use Across Targeted Applications
This exhibition marked a major turning point for sodium-ion batteries. The technology has moved beyond concept displays and sample demonstrations and has officially entered the first year of large-scale mass production. Production-ready cells, vehicle solutions, and complete energy storage systems were all presented, showing commercialization progress far faster than expected.
The rapid growth of sodium-ion batteries is driven by several clear advantages:
Strong cost and supply chain benefits
Sodium is widely available worldwide and easy to obtain, with no supply risks like lithium or cobalt. As production scales up, sodium-ion battery costs are approaching those of LFP batteries, offering strong price competitiveness.
Excellent performance in extreme environments
Sodium-ion batteries can operate reliably from -40°C to 60°C. They perform well in very cold or very hot conditions, with much less range loss in cold regions. This also makes them suitable for outdoor energy storage equipment.
Clear and focused application positioning
These batteries are mainly used in short-range electric vehicles, hybrid systems, low-speed commercial vehicles, backup power for communication base stations, and small home energy storage systems. They effectively fill gaps where traditional lithium batteries are less suitable, creating strong differentiated advantages.
At present, leading battery manufacturers in China are bringing sodium-ion production lines online, and supporting supply chains for materials, separators, and electrolytes are becoming more complete. Within this year, multiple sodium-ion vehicles and energy storage projects are expected to be delivered in batches, making sodium-ion batteries one of the fastest-growing new tracks in the battery industry.
2.3 Solid-State and Semi-Solid Batteries Make Breakthroughs as Next-Generation Solutions Enter Validation Stage
Solid-state batteries are widely seen as the ultimate direction for lithium battery development. At this exhibition, solid–liquid hybrid technologies achieved important breakthroughs. Semi-solid batteries are moving into industrial production, while all-solid-state batteries are steadily progressing through pilot testing. Clear timelines are now in place, marking the beginning of the next battery upgrade cycle.
Semi-solid batteries enter mass production first
The biggest advantage of semi-solid batteries is strong compatibility with existing lithium battery production lines. With only minor equipment upgrades, manufacturers can begin production without heavy investment in new factories. These batteries offer noticeably higher energy density than traditional lithium batteries, along with improved thermal safety and overall reliability. They are well suited for high-end, long-range electric vehicles and serve as an ideal transition between liquid lithium batteries and fully solid-state batteries.
All-solid-state batteries steadily move forward
Leading companies displayed all-solid-state battery samples with strong real-world performance, including very high energy density, greatly reduced fire risk at a physical level, and ultra-fast charging—up to 80% in about 10 minutes. At the same time, solid electrolytes, new electrode materials, and advanced packaging components are becoming more mature, while production processes continue to improve.
Most industry leaders now agree that small-scale vehicle use of all-solid-state batteries could begin around 2027. In the long term, the market potential for this technology is very large.
