This technology could also be used to provide low-intensity indoor lighting, or to transform trees into self-powered streetlights, the researchers say.
Power conversion is intrinsically inefficient: A power converter will never output quite as much power as it takes in.
Now MIT researchers have developed an “air-breathing” battery that could store electricity for very long durations for about one-fifth the cost of current technologies
The collapse of electricity prices due to expansion of nonfossil energy is already happening and will continue to increase as renewable energy installations increase.
Most of today’s lithium-ion batteries, which power everything from cars to phones, use a liquid as the electrolyte between two electrodes.
These collaborations over the past 10 years have led to groundbreaking discoveries and innovations, such as a first-of-its-kind liquid metal battery for large-scale energy storage.
