Battery Chemistry Breakdown
Lithium-ion Batteries
- Lithium Iron Phosphate (LFP): LFP batteries continue to dominate the market due to their safety, low cost, and long cycle life. In the first half of 2024, LFP batteries accounted for 69.32% of total power battery installations, a share that has grown steadily over the past few years.
- Nickel-Manganese-Cobalt (NMC): NMC batteries, while still popular, have seen their market share decline slightly, accounting for 30.63% of installations. However, NMC batteries continue to be favored in performance-oriented EVs due to their higher energy density.
Emerging Technologies
- Sodium-Ion Batteries: In the first half of 2024, sodium-ion batteries made their debut in the Chinese market, with 1.5 megawatt-hours (MWh) of installations. Their low cost and abundance of sodium resources make them an attractive alternative to lithium-ion batteries.
- Semi-Solid-State Batteries: Semi-solid-state batteries also entered the market, with 2154.7 MWh installed in the first half of the year. These batteries offer improved safety and energy density, but their high cost remains a challenge for widespread adoption.
Market Shares and Competition
The power battery market in China is highly concentrated, with the top 10 battery manufacturers accounting for 96.1% of total installations in the first half of 2024. The following table summarizes the market shares of the leading players:
| Company | Installed Capacity (GWh) | Market Share (%) |
|---|---|---|
| CATL | 93.31 | 46.38 |
| BYD | 50.51 | 25.10 |
| Zhongchuang Xinhang | 13.83 | 6.87 |
| EVE Energy | – | – |
| Guoxuan Hi-Tech | – | – |
| Hive Energy | – | – |
| Sunwoda | – | – |
| Ruipu Energy | – | – |
| ZL Power | – | – |
| LG Chem | – | – |
Note: Installations by EVE Energy, Guoxuan Hi-Tech, Hive Energy, Sunwoda, Ruipu Energy, ZL Power, and LG Chem are included in the total for the top 10 but not individually listed due to space constraints.
CATL and BYD continue to dominate the market, with CATL maintaining its lead with a 46.38% market share. However, the market concentration has slightly decreased from previous years, indicating increased competition and market entry by new players.
Export Growth
Chinese battery manufacturers have also seen significant growth in exports. In the first half of 2024, China exported a total of 73.7 GWh of power batteries and energy storage batteries, an increase of 18.6% YoY. Power battery exports accounted for 60 GWh of this total, while energy storage battery exports surged 106.7% YoY to 13.6 GWh.
Energy Storage Battery Market Expansion
Market Dynamics
The energy storage battery market in China has witnessed explosive growth in recent years, fueled by the increasing penetration of renewable energy sources and the need for grid stability. According to CABII, energy storage batteries accounted for 21% of total battery sales in the first half of 2024, with a YoY growth rate of 137.3%.
Key Drivers
- Renewable Energy Integration: The integration of solar and wind power into the grid requires large-scale energy storage systems to balance supply and demand fluctuations.
- Grid Stability: Energy storage batteries play a crucial role in ensuring grid stability, especially during peak demand periods.
- Policy Support: The Chinese government has implemented various policies to support the development of the energy storage industry, including subsidies and investment incentives.
Market Shares and Competition
Leading battery manufacturers such as CATL, BYD, and EVE Energy have all expanded their energy storage business, viewing it as a significant growth opportunity. The following table summarizes the revenue contributions of energy storage batteries for select companies in 2023:
| Company | Energy Storage Revenue Contribution (%) |
|---|---|
| CATL | 14.7 |
| EVE Energy | 33.5 |
| Voltcoffer | 21.93 |
CATL, despite being the market leader in power batteries, has a relatively lower share in energy storage, indicating ample room for growth. EVE Energy and Voltcoffer, on the other hand, have dedicated significant resources to their energy storage businesses.
International Presence
Chinese battery manufacturers are increasingly looking beyond domestic markets, signing large-scale energy storage battery contracts in overseas markets. In recent months, companies like EVE Energy, CATL, and Guoxuan Hi-Tech have secured major contracts in Europe, North America, and Southeast Asia. This trend is expected to continue as the global energy transition accelerates and the demand for energy storage solutions grows.
