Fluorine ion battery has been developed, with energy storage 10 times higher than that of lithium battery?

　　Despite the rapid development of the global electric vehicle industry, the market has been mixed. Its biggest advantages are relatively mature technology and low vehicle costs, but its disadvantages are short cruising range and long charging time, which have become the biggest factors plaguing the development of electric vehicles. At present, power batteries such as lithium iron phosphate, lithium titanate, and lithium ion have basically reached their bottleneck, and it is difficult for them to have a cruising range of more than 600 kilometers, resulting in more than 80% of models having a cruising range of less than 500 kilometers.

　　Recently, Japanese car company Honda announced the development of a new fluoride-ion battery technology, which not only has 10 times more energy storage energy than current lithium-ion batteries, but is also more environmentally friendly and is expected to become the preferred battery for electric vehicles in the future.

　　Researchers from Honda Research Institute, California Institute of Technology, and NASA's Jet Propulsion Laboratory announced this important breakthrough on December 7.

　　Researchers say that this new fluoride-ion battery has an energy density ten times that of ordinary lithium-ion batteries, but it has very good stability. Moreover, its manufacturing materials can be extracted directly from the land, making it cheaper to manufacture and less harmful to the environment. The impact is also very small.

　　According to reports, this technology for manufacturing fluoride-ion batteries has appeared a long time ago, but the batteries produced by this technology must operate at a temperature of 300 degrees.

　　This time, a joint research and development team from four institutions found a way to allow this battery to operate at room temperature without overheating problems. Researchers say the new technology circumvents the temperature limitations of fluoride battery technology and opens up a path to high-energy-density batteries.
