People with electric vehicle mileage anxiety may be relieved. At present, the lithium battery for electric vehicle power is experiencing breakthrough progress. More and more vehicle enterprises are competing to release the forecast, and the driving range of their next generation electric vehicles will be greatly improved. Recently, the Renault Nissan Alliance announced that it plans to increase the driving range of its pure electric vehicles to more than 400 kilometers by 2020 at the latest, which is twice the current range. By improving the material and design of the battery, Nissan LEAF can store twice as much power as before, and its cost is almost the same as the current one.

Due to the high cost and short driving range, the sales of pure electric vehicles have not been satisfactory. With the breakthrough of battery technology and the substantial increase of driving range under the condition of keeping the cost unchanged, pure electric vehicles are expected to be vigorously popularized in the future. In this process, battery suppliers of electric vehicles will play a key role. LG Chem, a Korean supplier of lithium batteries, has been in the limelight for a while. The company said that it has made breakthroughs in battery materials, design and chemical composition. The new battery will have higher energy density and will provide longer driving range. At present, LG Chem has almost contracted the battery supply of most mainstream automobile brands in the world.

Volkswagen will adopt unified battery unit in the future

Recently, Volkswagen Group announced that it will announce the battery selection method of its pure electric vehicles before July this year. In the future, electric vehicles under large groups are expected to use a single lithium battery cell. It is reported that Volkswagen is developing the next generation lithium battery cell technology, and the energy density can reach as much as 5 times of the current battery. This will make the battery pack of the Volkswagen electric vehicle smaller and have a larger driving range.

Noza, the head of research and development of Volkswagen, said recently that all the electrified vehicles of Volkswagen Group may turn to a single lithium battery unit in the future. Now, we have clearly realized that we should use universal battery cells, which means that each model and brand under Volkswagen will use a unified battery cell, and only in this way can we achieve synergy. He said. Volkswagen plans to reduce the cost of batteries by 66% through the use of unified battery cells.

At present, various types and brands of lithium battery cells are used in Volkswagen's electric vehicles. For example, e-Golf, Golf GTE plug-in hybrid vehicles and Audi A3 use Panasonic batteries, while the forthcoming Passat GTE and other Audi electric vehicles are supplied by Samsung.

In addition to the substantial reduction of battery costs, the energy density of the next generation of lithium battery units that Volkswagen is developing will also be significantly increased, which can be more than five times the current level, so that the driving range of the electric vehicles under Volkswagen Group will usher in a major breakthrough. However, Volkswagen did not disclose how to achieve this breakthrough. Foreign media speculated that Volkswagen might turn to solid-state batteries in the future.

Heroes challenge TSLA driving range

In addition to Renault Nissan and Volkswagen, there are now at least two automobile manufacturers planning to challenge TSLA and launch the first pure electric vehicle with a driving range of more than 200 miles (322 kilometers) at affordable prices. These two automobile enterprises are General Motors and Ford. The new generation electric vehicles of these automobile manufacturers are expected to enter the market in the next two to three years.

At present, Nissan Leaf sells for 29010 dollars, with a driving range of 228 kilometers; The TSLA Model S with 265 miles (427 km) of driving range will sell for $81000. However, at this stage, the driving range of most affordable electric vehicles is only 75~85 miles (121~137 kilometers), and the driving range will shrink under low temperature or air conditioning conditions.

TSLA CEO Jack Musk once said: 200 miles is the minimum standard for consumers on the driving range of electric vehicles, and their real ideal mileage is 250~350 miles. Recently, Musk announced at the investor meeting that the new mid-range car Model3 is expected to be launched in March 2016. Although the driving range is not comparable to the ModelS, the driving range will also reach 320 kilometers, and the price will be much more user-friendly, starting at about 35000 dollars.

With the increasingly stringent greenhouse gas emission regulations in the United States, automobile manufacturers may have to make more efforts on pure electric vehicles. At present, California's zero emission vehicle camp also includes plug-in hybrid vehicles, but California and several other major states plan to exclude them from the zero emission vehicle camp by 2018, focusing on real zero emission vehicles.

LG Chemical takes the lead in the supply chain

American carmakers General Motors and Ford are also adding to the range of electric vehicles. At this year's North American International Auto Show, GM announced its new electric car, the Chevrolet Bolt, and the driving range of the new car will be increased to 320 kilometers after a single charge. Ford plans to launch a new all electric vehicle with a driving range of more than 200 miles (about 322 kilometers), and its competitors are directly targeting the Chevrolet Bolt and TSLA Model 3.

Battery suppliers play a crucial role in the mileage battle. In this regard, LG Chem of South Korea can be said to be proud of all the others. The above mentioned car companies are more or less related to LG Chem. Compared with Panasonic and AESC, the other two giants of global electric vehicle battery manufacturers, LG Chem has a stronger development momentum. Among the top 20 auto brands in the world, LG Chem has cooperated with 13 of them.

It is reported that LG Chem will supply lithium battery packs for Chevrolet Bolt, and it will also supply standard lithium batteries for Ford Focus electric vehicles. It is expected to continue to supply batteries for the next generation of compact electric vehicles built by Ford in the future. In the first quarter of this year, Nissan LEAF was far ahead in global sales. The battery used by LEAF 2015 is from AESC, a joint venture between Nissan and NEC, a supplier. In addition, Nissan and Volkswagen also have battery supply agreements with LG Chem, but it is unclear whether Nissan's battery supply for future models will turn to LG Chem.

Recently, LG Chem of South Korea announced that it will supply batteries for plug-in hybrid vehicles (PHEVs) produced by Great Wall Motors in batch from 2017, taking the lead in China's market.
