New lithium-ion battery

Researchers at the University of Illinois at Urbana-Champaign have developed a new lithium-ion battery technology that is 2,000 times more powerful than comparable batteries. According to the researchers, this is not simply an evolutionary step in battery tech, “It’s a new enabling technology… it breaks the normal paradigms of energy sources. It’s allowing us to do different, new things.”

Currently, energy storage is all about trade-offs. You can have lots of power (watts), or lots of energy (watt-hours), but you can’t generally have both. Supercapacitors can release a massive amount of power, but only for a few seconds; fuel cells can store a vast amount of energy, but are limited in their peak power output. This a problem because most modern applications of bleeding-edge tech — smartphones, wearable computers, electric vehicles — require large amounts of power and energy. Lithium-ion batteries are currently the best solution for high-power-and-energy applications, but even the best li-ion battery designs demand that industrial designers and electronic engineers make serious trade-offs when creating a new device.
