Cover News ｜ BMW adopted a new cylindrical battery in 2025. The two Chinese companies have won over 10 billion euros.

On September 9th, the cover news learned from the BMW Group that BMW will take the lead in using cylindrical cells in the "new generation" model since 2025. The perfect matching of the new battles technology with a new architecture is perfectly matched, which not only greatly improves energy density, battery life and charging speed, but also reduces carbon footprint and resource consumption in the battery manufacturing.

It is reported that BMW is the sixth -generation EDRIVE power -driven technology. It has developed a new cell form and chemical system. The new cylindrical cells designed for the electronic electronics architecture of the "new generation" model can increase the battery life up to 30%; and the fifth Compared with the square cell cell, the nickel content contained in the positive electrode of the sixth -generation cylindrical cells is higher, the cobalt content is reduced, and the silicon content contained in the negative electrode has increased. It will increase by more than 20%.

The new cylindrical cell has a standard diameter of 46 mm and two different heights. Depending on the models, the battery will be effectively integrated in the body structure. The space required by the original battery module will be greatly optimized.

The voltage platform of the "new generation" model's battery, power system and charging technology will also be increased to 800 volts, thereby optimizing the energy supply of DC fast charge charging stations. The current of up to 500 ampel can greatly increase the charging power. Thanks to this, high-voltage power battery power has decreased by as much as 30%from 10-80%.

In addition, the sixth -generation battery cell technology will also provide lithium iron phosphate (LFP) as the choice of cathode material for the first time, thereby further avoiding the use of raw materials cobalt and nickel in cathode materials. The company is also constantly promoting the development of solid -state batteries (ASSB), and the target setting the application of solid high -voltage batteries to mass production by 2030.

It is worth mentioning that in order to meet the needs of the "new generation" model for the battery cell, BMW has granted the two partners of Ningde and EVE ENERGY (CATL) and EVE ENERGY. Production demand contract. These two partners will establish two battery factories in each of China and Europe, and the annual capacity of each factory will reach 20 GWh.

With the rapid growth of product array and market demand, by the end of 2025, BMW plans to deliver more than 2 million pure electric vehicles worldwide. Prior to 2030, the BMW Group's pure electric models will account for 50%of its global sales. At that time, the other three major brands of the BMW Group will also be comprehensively electrified: the Rolls -Royce brand will complete all the products of the product; the BMW Motorrad urban travel series will all be electrified; the Mini brand will also start from the early 1930s. Electricity to comprehensive.
