Scientists Invent Self-healing Battery Electrode
Researchers have made the first battery electrode that heals itself, opening a new and potentially commercially viable path for making the next generation of lithium ion batteries for electric cars, cell phones and other devices. The secret is a stretchy polymer that coats the electrode, binds it together and spontaneously heals tiny cracks that develop during battery operation, said the team from Stanford University and the Department of Energy’s (DOE) SLAC National Accelerator Laboratory.
Designer Glue Improves Lithium-ion Battery Life
When it comes to improving the performance of lithium-ion batteries, no part should be overlooked – not even the glue that binds materials together in the cathode, researchers at SLAC and Stanford have found.
New Battery Design Could Help Solar and Wind Energy Power the Grid
Menlo Park, Calif. — Researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a low-cost, long-life battery that could enable solar and wind energy to become major suppliers to the electrical grid.
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.
SLAC Joins Partnership to Develop Energy Storage R&D Hub
SLAC and Stanford will join a team that will receive $120 million from the DOE to establish a new batteries and energy storage hub – the Joint Center for Energy Storage Research (JCESR).
