　　According to British media reports on February 14, BMW plans to announce breakthrough innovative vehicle battery technology in 2026 to reduce weight and improve battery performance.

　　BMW said that the new lithium-ion battery will use solid electrolyte instead of liquid electrolyte, which can increase the electric capacity by 15-20%. The weight of the battery pack is also expected to be reduced, while the new cells can be protected by less casing due to a reduced risk of fire and upgraded safety. However, the new battery pack is still in the research and development stage and has to undergo long-term performance testing, and will not be mass-produced for nearly ten years.

　　The latest progress in BMW's battery technology will be announced when the 2018 Mini Cooper E and the new generation of pure electric X3 are released. In addition, BMW AG will continue to develop its internal combustion engine technology. BMW's conventional engines are 33% efficient, compared to 90% for the electric powertrain.
