Egg-cellent World-record Battery Performance

SLAC and Stanford scientists have set a world record for energy storage, using a clever “yolk-shell” design to store five times more energy in the sulfur cathode of a rechargeable lithium-ion battery than is possible with today’s commercial technology. The cathode also maintained a high level of performance after 1,000 charge/discharge cycles, paving the way for new generations of lighter, longer-lasting batteries for use in portable electronics and electric vehicles.

Building a Better Battery for Renewable Energy Storage

Solar, wind and other renewable energy sources reduce consumption of fossil fuels but also pose challenges to the electrical grid because their power generation fluctuates, heightening the need for better battery technology to store their energy until it's needed to feed the grid.

Stanford-SLAC Team Uses X-ray Imaging to Observe Running Batteries in Real Time

Most electric cars, from the Tesla Model S to the Nissan Leaf, run on rechargeable lithium-ion batteries – a pricey technology that accounts for more than half of the vehicle's total cost. One promising alternative is the lithium-sulfur battery, which can theoretically store five times more energy at a much lower cost.

Postdoc Eric Verploegen Energized by Experiences, Mentoring at SLAC

If the excitement and enthusiasm of young scientists like Eric Verploegen could be pumped directly into the power grid, the world's energy problems could be solved tomorrow.

It can't, though. So Verploegen has made it his goal to channel his energy into looking for solutions the old-fashioned way – hard work, and lots of it.
