New energy vehicles (NEVs) are powered by unconventional fuels or advanced power systems that integrate vehicle control and drive technologies. These vehicles represent a significant technological advancement, combining new materials, structures, and energy solutions. At the heart of these vehicles lies the new energy battery, which serves as the primary power source.
**1. Lead-Acid Battery**
Lead-acid batteries are one of the most established technologies in the automotive industry. They are widely used in electric vehicles due to their low cost and high discharge rate. For example, during the Beijing Olympics, 20 electric vehicles equipped with lead-acid batteries provided transportation services. However, these batteries have limitations in terms of specific energy, power, and energy density, which restrict the speed and range of electric vehicles.
**2. Nickel-Cadmium and Nickel-Metal Hydride Batteries**
Nickel-cadmium (Ni-Cd) and nickel-metal hydride (Ni-MH) batteries offer better performance than lead-acid batteries but come with environmental concerns due to the presence of heavy metals. Ni-MH batteries are particularly popular in hybrid vehicles, with Toyota’s Prius being a prime example. Currently, 99% of hybrid vehicles use Ni-MH batteries, with companies like PEVE and Sanyo leading the market. In China, several automakers such as Chery and Geely also use these batteries, though many still rely on imported components.
**3. Lithium-Ion Batteries**
Lithium-ion batteries are increasingly favored by automakers for their high energy density, long cycle life, and lightweight design. They offer advantages such as high voltage, large specific energy, and no memory effect. Major automakers like Ford, Toyota, and BYD have adopted lithium-ion technology in their hybrid and electric vehicles. However, challenges remain in ensuring safety and balancing charge-discharge cycles across multiple cells.
**4. Lithium Iron Phosphate (LiFePOâ‚„) Battery**
A type of lithium battery, LiFePO₄ offers enhanced safety, stability, and a longer cycle life compared to other lithium variants. It is more affordable and is gaining popularity in the automotive sector. BYD’s “iron battery†is believed to be based on this technology.
**5. Fuel Cell**
Fuel cells generate electricity through chemical reactions between hydrogen and oxygen, offering a clean and efficient power source. Proton exchange membrane (PEM) fuel cells are considered the most promising for automotive applications. Unlike traditional batteries, fuel cells function more like a power plant, continuously producing electricity as long as fuel is supplied.
**Market Trends and Production Data**
In August 2017, domestic new energy vehicle production reached 72,000 units, while sales hit 68,000. From January to August, total production was 346,000 units, and sales totaled 302,000. Power batteries, a critical component, saw significant growth, with lithium battery installations reaching 2,924.8 MWh in August alone.
CATL, a leading Chinese manufacturer, held the top position in battery installation capacity, with 1,262.41 MWh installed in August. Cumulatively, CATL accounted for 28.2% of the market share, highlighting its dominance in the sector.
**Future Outlook**
Nickel-hydrogen batteries are currently the most mature technology and will likely remain dominant for the next few years. Over time, they may be gradually replaced by lithium-ion and fuel cell technologies, which offer higher efficiency and sustainability. As the demand for cleaner and more efficient transportation grows, the evolution of battery technology will play a crucial role in shaping the future of the automotive industry.
