Why is the battery soft? Revealing the technology and market hot spots of soft pack batteries
Recently, with the rapid development of new energy technology, soft-pack batteries have become a hot topic in the industry. Many users have discovered that some batteries are soft to the touch, which is completely different from the traditional impression of hard batteries. This article will analyze the principles, advantages and market dynamics of soft-pack batteries based on hot data from the entire network in the past 10 days.
1. Why are soft pack batteries soft?
The pouch cell uses aluminum-plastic composite film as the outer shell material, and the interior is a stacked electrode design. Compared with traditional steel shell/aluminum shell batteries, its core differences are as follows:
| Contrast Dimensions | Soft pack battery | Hard case battery |
|---|---|---|
| Shell material | Aluminum plastic composite film | Metal (steel/aluminum) |
| gravimetric energy density | High (lightweight) | lower |
| shape adaptability | Customizable special shapes | Fixed cylindrical/square |
2. Recent hot events on soft pack batteries (last 10 days)
| Date | event | heat index |
|---|---|---|
| 2023-11-05 | CATL releases a new generation of soft-pack batteries with a 15% increase in energy density | 924,000 |
| 2023-11-08 | Tesla Cybertruck is revealed to use soft pack battery pack | 876,000 |
| 2023-11-12 | LG New Energy announces mass production of soft pack batteries exceeds 100GWh | 792,000 |
3. Three major technical advantages of soft pack batteries
1.high energy density: The aluminum-plastic film shell is 30% lighter than the metal shell, which increases the overall energy density of the battery pack by 10-15%.
2.Good safety performance: Soft materials can release pressure through bulging when thermal runaway occurs, reducing the risk of explosion.
3.Flexible design: Can be made into ultra-thin (thinnest 0.45mm) or special-shaped batteries, suitable for special scenarios such as smart wearable devices.
4. The five major issues consumers are most concerned about
| question | Search volume (daily average) | Technical solutions |
|---|---|---|
| Will soft pack batteries leak? | 58,000 | The aluminum-plastic film sealing technology is mature and the leakage rate is <0.01%. |
| How long do soft batteries last? | 43,000 | Cycle life reaches 800-1200 times (equivalent to hard shell) |
| Why don’t mobile phones use soft batteries? | 36,000 | Most flagship phones have adopted it (such as Samsung Galaxy series) |
5. Forecast of future trends
According to industry data, the global soft pack battery market share has reached 38% in 2023, and is expected to exceed 45% in 2025. The main growth drivers come from:
1. Demand for lightweight batteries for electric vehicles
2. Explosive growth of flexible electronic devices
3. High standard requirements for safety of energy storage systems
Experts remind: Although soft pack batteries have obvious advantages, you still need to be careful when purchasing.UL/IEC certificationproducts and avoid buying low-quality batteries without protection circuits.
