Brief description of the global power battery technology and market trends Super battery is not a dream

Roland Berger predicts two major "weaknesses" that will hinder the development of electric vehicles in five years - the cost and performance of batteries - will make major breakthroughs. And once the technological breakthrough in the battery area means that the electrified powertrain system will be fully popularized.

The forecast from Roland Berger shows that the increasingly stringent environmental regulations in the world and the mandatory carbon dioxide emission reduction measures will make great progress in electric mobility in the coming years.

As the core cost of electric vehicles battery, the price will also experience a sharp downward trend. Due to the ever-increasing scale and breakthrough in core technologies, in 2015, the average cost of about 250 US dollars / kWh EV battery, by 2020, will drop to 130-150 US dollars / kWh, a decline of 40%.

With the substantial reduction in battery costs, pure electric vehicles and plug-in hybrid electric vehicles are expected to become truly competitively priced products on the market by 2025 and will therefore be mass-produced.

As long as the timely construction of infrastructure facilities, a strong market demand will promote the global consumer large-scale consumption of electric vehicles, short-range use of pure electric vehicles, plug-in hybrid electric vehicles a little longer distance.

For different global markets and regions, the proportion is slightly different. In Europe, pure electric and plug-in hybrids will account for 9% of all vehicles sold in 2020 and 31% in 2025; and in 2020, pure electric and plug-in hybrids in all markets sold 7% in volume, 32% in 2025 and 11%, 24%, 22% and 42% respectively in the United States and Japan.

By then, nearly a third of the world's cars will become electrically powered, and a battle for battery makers is starting for battery makers. The biggest obstacle to the promotion of electric vehicles is the consumer's mileage anxiety disorder and the battery price is too high. In response, the major companies are focused on the efforts, in addition to the well-known Tesla in the research and development and manufacture of battery action, the car manufacturers and auto parts manufacturers also began the layout in the field of batteries.

Volkswagen CEO Martin Winterkorn recently said Volkswagen is developing a "Super-battery" that will extend the current range of electric vehicles to 300 kilometers (186 miles). Developed in Silicon Valley, California, USA, the battery is smaller, more powerful and less expensive. Volkswagen battery research technology route is currently focused on the existing lithium-ion battery upgrade solutions and novel solid-state battery technology in two directions.

The company's approach to reducing battery costs is to use a single, unified cell. That is, all future electric vehicles, though of different models, may have a uniform number of cells in different package sizes and Volkswagen expects to reduce battery costs by about 66% due to simplified cell design. At the same time, the energy density can reach 5 times the current battery.
