Compared to other technological advancements, batteries have improved little over the past years. The average gain in capacity is about 6% per year. In contrast, since 1990 disk capacity has increased by 4,000 times, while energy density of rechargeable batteries has increased just threefold.
Today, battery capacity is a bottleneck in product innovation. When new products are developed, engineers work around the constraints of a power source. Battery cells that are light, powerful and long-lasting can eliminate the energy bottleneck and enhance product development in a variety of industries.
