-Higher Energy Density: The stacking process allows more active materials to be accommodated in a limited volume, enabling greater electrical energy storage per unit volume or weight, which directly enhances the endurance capability of devices.
- Better Charge-Discharge Performance: Its low internal resistance supports high-rate charging and discharging, achieving fast charging (e.g., 80% charge in 10-15 minutes) and instantaneous high-power output to meet the short-term high-power demands of devices.
- Enhanced Safety: The stacked structure reduces internal stress within the cells and ensures more uniform heat distribution. Combined with optimized separators and short-circuit prevention designs, it lowers safety risks such as thermal runaway and fire hazards.
- Flexible Adaptation to Diverse Form Factors: It can achieve ultra-thin and irregular designs by cutting electrode shapes, flexibly fitting special structural needs such as flat battery packs, foldable screen hinges, and curved spaces in wearable devices.
- Longer Cycle Life: The stacking process reduces the shedding of active materials and electrode deformation, maintaining high capacity even after thousands of charge-discharge cycles (typically retaining over 80% capacity after 2000 cycles), thus extending the service life of the battery.
- Compatibility with High-Capacity and High-Voltage Requirements: Through series/parallel combinations of multiple cells, it can easily achieve high-voltage output (e.g., 300-800V platforms for new energy vehicles) and large-capacity storage (e.g., over 100kWh for energy storage systems), meeting the needs of high-power devices.
FAQ
1. What is a stacked lithium-ion battery? How does it differ from traditional wound lithium-ion batteries?
A stacked lithium-ion battery is a type of battery cell formed by layering positive electrodes, separators, and negative electrodes one by one (similar to a "sandwich" structure). The core difference from traditional wound lithium-ion batteries lies in the electrode assembly process:
- Stacked type: Electrodes are layered through a lamination process, allowing more flexible electrode shapes (square, irregular, etc.) and higher internal space utilization.
- Wound type: Electrodes are rolled into cylindrical or prismatic cells. While the technology is mature, electrodes require continuous cutting, resulting in slightly lower space utilization.
Additionally, stacked batteries offer better charge-discharge uniformity, making them more suitable for high-rate, large-capacity scenarios such as electric vehicles and energy storage devices.
2. What is the typical lifespan of stacked lithium-ion batteries? What factors affect their lifespan?
The cycle life of stacked lithium-ion batteries is usually over 1,000-3,000 cycles (depending on materials, craftsmanship, and usage conditions). Key factors affecting lifespan include:
- Charge-discharge conditions: Overcharging (exceeding rated voltage), deep discharge (remaining capacity below 20%), or high-rate fast charging can accelerate electrode aging.
- Operating temperature: Long-term use in high-temperature environments (above 45°C) or low-temperature environments (below -20°C) can cause electrolyte decomposition or lithium dendrite growth.
- Production process: Insufficient lamination alignment accuracy may lead to local current concentration, accelerating internal cell loss.
3. Are stacked lithium-ion batteries safer? How to avoid safety hazards?
Relatively speaking, stacked lithium-ion batteries offer better safety due to: The laminated structure distributes stress more evenly, and separators are less likely to wrinkle or tear due to winding tension, reducing short-circuit risks; additionally, square casings are easier to integrate safety devices such as explosion-proof valves.
To avoid safety hazards:
- Choose products from reputable manufacturers to ensure electrode alignment accuracy and separator quality;
- Use matching chargers to prevent overcharging and over-discharging;
- Avoid severe collisions,extrusion or storage in high-temperature environments.
