In 2009, IBM Research pioneered a sustainable mobility project to develop lithium-air battery technology capable of powering a family-sized electric car for approximately 500 miles (800 km) on a single charge.
As partners in the Battery 500 Project, Asahi Kasei and Central Glass bring decades of materials innovation for the automotive industry to the team. They will expand the project’s scope and, although the scientific and engineering challenges to its practical implementation are extremely high, exploring several chemistries simultaneously increases the chance of success.
- Central Glass, a leading global electrolyte manufacturer for lithium-ion batteries, will use its chemical expertise in this field to create a new class of electrolytes and high-performance additives specifically designed to improve lithium-air batteries.
Most electric vehicles can only travel about 100 miles before needing to recharge using today’s lithium-ion batteries. This is a significant barrier to electric car adoption unless a new battery technology can be developed that is affordable, lightweight, compact and has the capacity to power a typical family car several hundred miles or more on a single charge.
For a car running on today’s lithium-ion batteries to match the range provided by a tank of gasoline, car manufacturers would need a very large battery which would weigh down the car and take up too much space. Lithium-air batteries have higher energy density than lithium-ion batteries, due to their lighter cathodes and the fact that their primary "fuel" is the oxygen readily available in the atmosphere. To popularize electric cars, an energy density ten times greater than that of conventional lithium-ion batteries is needed, and these new partners to the project can help drive lithium-air technology towards that goal.
