Many systems and devices we use every day, including our cell phones and laptops, require batteries. Electric cars, solar and wind farms, and off-grid homes need much larger batteries. And we expect smart clothes and the internet to change how we live and how we gather and consume information in the near future. They will all need to be powered, but by much smaller, more flexible, and longer-lasting energy storage devices. The speakers presented on the discovery of the lithium battery and the long journey from the Sony camcorder battery to the modern lithium-ion battery. They also explained what is coming after lithium-ion batteries. In particular, “batteries on steroids,” or electrochemical capacitors, that now power buses in many Chinese cities, open the doors of an Airbus 380 in an emergency, and harvest braking energy from SEPTA trains, will be discussed. Finally, future flexible, transparent, microscale, wearable, and other energy storage devices that are expected to become ubiquitous within the next decade will be discussed.
