Palo Alto, California-based electric car company, Tesla, is pioneering some of the most innovative advances in electric car technology. Not only that, but Tesla vehicles are actually cool, sporty, and fast. The problem, however, that has plagued Tesla and other electric car manufacturers is battery life. Now, the company is teaming up with tech specialists at Panasonic Corp. to develop a longer lasting battery.

Currently, Tesla’s sporty Roadster model cars can travel up to 245 miles on a single charge. But next year, Tesla is planning on releasing its Model S—a four-door sedan—and wants the car to travel even further on a single charge. The company would like to see the Model S traveling at least 300 miles per charge.

Tesla already boasts the most powerful batteries among commercial electric car models, and even supplies its components to some competitors, such as Toyota Motor Corp. and Daimler AG. “Our battery pack has 56 kilowatt hours of energy. Other EVs on the market have about 20 or 24 kilowatt hours,” says Kurt Kelty, director of battery technology for Tesla.
