BMW plans to start using solid-state batteries in 2030

According to the view of foreign media, many enterprises have been talking about "battery breakthrough" for many years. However, the battery technology itself has not ushered in any real breakthrough in recent years. Although the battery has made progress in terms of safety, capacity and energy density, the mileage of electric vehicles has also been improved, and the price of the battery is also going down. in fact, however, battery technology has not achieved significant, groundbreaking progress that can change the industry. More specifically, solid-state batteries are not yet widely used in the automotive industry.

Current electric vehicles use lithium batteries, in which there is a liquid electrolyte between the anode and the cathode. The solid-state battery changes the liquid electrolyte into solid, so as to improve the performance and safety of the battery.

There are reports that solid-state batteries are about to become popular, but this may not happen soon. There are many companies around the world dedicated to the development of solid-state batteries, some of which have found a new direction for themselves, while others are still not ready to announce new breakthroughs in the short term.

BMW is one of them, and although it has recently been reported that the company is "committed to starting using solid-state batteries by 2025," the exciting headlines do not mention whether these batteries will actually be used in cars. Solid-state battery technology exists today, and its effectiveness has been proved. But it is not ready to be widely used in cars.

If you read carefully about BMW's solid-state battery program, you will see that the company's plan is to apply solid-state battery technology to passenger cars in 2030, that is, in about 10 years, rather than four to five years later. But BMW did say it plans to launch a "demonstration car" with solid-state batteries in 2025.

The company said its researchers were working hard on solid-state batteries and said cell development was at the heart of the company's transformation of electric vehicles. The project will put BMW in competition with carmakers such as Volkswagen and Toyota, which hope to use solid-state batteries in their electric vehicles in the coming years. Frank Weber, head of BMW's development, said: "by 2030, we will have car-grade solid-state batteries and apply them to our vehicles."

BMW has been telling people about its future battery technology, but this is the first time the company has provided a timetable for the application of the technology. "the greenest vehicle in the world will be BMW," Weber said. We are developing the cell of the future, which will have strong performance and will be safe, cost-effective and recyclable. All of this will be created in the European value chain. "

If all goes well, solid-state batteries will greatly increase the range of electric vehicles. BMW claims that its technology can increase the energy density of the battery by about 50%. In addition, BMW hopes to use its new technology to reduce the price of electric vehicles to the same level as gasoline models in the future. Finally, the company will also devote itself to the recycling of batteries.
