Why are Grignard batteries so expensive?
In recent years, Grepow batteries have become the focus of the market due to their high performance and unique technology, but their high prices have also discouraged many consumers. This article will analyze the reasons for the high price of Grignard batteries from multiple dimensions such as technology, materials, and market, and attach relevant data comparisons.
1. High cost of core technology
The core advantage of Grignard cells lies in its patented technology and manufacturing process. The following is a comparison of its key technologies with ordinary lithium batteries:
| Technical indicators | Grignard cell | Ordinary lithium battery |
|---|---|---|
| energy density | ≥300Wh/kg | 150-200Wh/kg |
| cycle life | 2000 times (capacity maintained at 80%) | 500-800 times |
| Low temperature performance | Normal discharge at -40℃ | Performance decreases by 50% at -20℃ |
2. High proportion of rare materials
The cathode material of the Grignard battery adopts a high-nickel ternary system (NCM811/NCA), and the content of precious metals such as cobalt and nickel is significantly higher than that of ordinary batteries:
| Material composition | Grignard cell | Ordinary ternary battery |
|---|---|---|
| Nickel content | 80% | 50-60% |
| Cobalt content | 5% | 10-20% |
| Material cost per kWh | About ￥800 | About ￥500 |
3. Market positioning and supply and demand relationship
Grignard batteries are mainly aimed at the high-end market, and their customer distribution and price range are as follows:
| Application areas | market share | Unit price (yuan/kWh) |
|---|---|---|
| Aerospace | 35% | 2500-3000 |
| medical equipment | 25% | 2000-2500 |
| High-end drone | 40% | 1800-2200 |
4. Investment in R&D and certification
The annual R&D investment of Grignard batteries accounts for more than 15% of revenue, which is much higher than the industry average. Some of its certification costs are as follows:
| Certification type | Single certification cost (10,000 yuan) | Validity period |
|---|---|---|
| UN38.3 (Air transport) | 50-80 | 3 years |
| CE certification | 30-50 | 5 years |
| military standard | 200+ | 5 years |
5. Summary
The high price of Grignard batteries stems fromtechnical barriers,Material scarcityandHigh-end market positioningThree core factors. Although the price is 2-3 times that of ordinary batteries, its advantages in extreme environmental stability, energy density and lifespan still make it irreplaceable in specific fields. With large-scale production and technology iteration, there may be room for price decline in the future.
