In the pure electric automobile manufacturing industry in the world, there is a trend that the entire vehicle company sinks into channels, either starting to unite to study batteries to establish battery factories, or the entire vehicle company is starting to pair up with large lithium battery manufacturers. "The research and development of the power battery began.

Not too long ago, a news story shocked the industry: Volkswagen CEO Martin Winterkorn revealed that the company is developing a "super-battery" that can dramatically increase the mileage of electric vehicles. Breakthrough in battery technology.

Wen Deen said, “VW is developing a super battery in Silicon Valley, California. The new battery is cheaper, smaller, and more powerful. An electric version of the Volkswagen brand (after carrying a super battery) is expected to have a pure electric range. It will reach 300 kilometers (186 miles). This will be a qualitative leap in electric vehicles (performance)."

In contrast, the EPA of the US Environmental Protection Agency stipulates that the average mileage of e-golf pure electric vehicles should reach 83 miles (about 133 kilometers). This means that if the Volkswagen "Super Battery" performance is on schedule, the electric vehicle's cruising range will be 2.26 times that of the EPA's demand for golf electric vehicles. Although the 300km cruising range is still not comparable to the 265 mile of the Tesla Model S, Volkswagen will introduce a more affordable electric vehicle, such as the next-generation e-Golf. Therefore, it is more significant than Model S to promote the popularization of electric vehicles.

In the past 18 months, Volkswagen Group has launched three electric vehicles, including e-Up, e-Golf (golf) pure electric vehicles and Golf GTE. However, the public is still cautious about developing pure electric vehicles.

Since the battery is far from the internal combustion engine in terms of energy density, the cruising range has long been one of the biggest weaknesses of electric vehicles. In the new regulations promulgated by many countries, only the electric vehicle's single charge cruising range has reached a certain level in order to enjoy preferential subsidy policies.

In the second quarter of this year, Volkswagen has stated that it will announce its battery-only options for pure electric vehicles by July 2015. It is developing next-generation lithium-ion battery cell technology that can achieve energy densities up to five times that of current batteries. Prior to this, the world’s top automakers were all producing power batteries.

In 2007, Nissan and its then battery giant NEC formed a joint venture company AESC focusing on the automotive battery business. Mitsubishi Motors and the giant battery GS Yuasa formed LEJ. Daimler and German Evonik set up a joint venture for automotive battery modules company Deutsche ACCUmotive. And battery company Li-Tec. Although General Motors and Tesla did not set up a joint-venture vehicle battery company with battery companies, they also established close cooperation with battery giants LG Chemical and Panasonic.

When Toyota developed a hybrid vehicle, it established a joint-venture vehicle battery company PEVE with Matsushita, and it has a mature and rich experience in battery cell manufacturing. Even so, Toyota is still doing two things in terms of lithium-ion batteries for electric cars: First, it will continue to cooperate with Matsushita, and second, it will produce its own.
