Today, 24M emerged from stealth mode to introduce the semisolid lithium-ion cell, a revolutionary technology that solves the grand challenge of energy storage by enabling a new, cost-effective class of the lithium-ion battery. 24M’s semisolid lithium-ion is the most significant advancement in lithium-ion technology in more than two decades and combines an overhaul in battery cell design with a series of manufacturing innovations that, when fully implemented, will slash today’s lithium-ion costs by 50% and improve the performance of lithium-ion batteries. The technology will accelerate the global adoption of affordable energy storage. Until now, the energy storage field has had two options to try to drive down costs – build massive and complex factories to produce lithium-ion batteries in high volumes or pursue entirely new chemistries that may never move from the lab to the commercial floor. With the invention of the semisolid lithium-ion battery, 24M presents a third option – work with the world’s preferred energy storage chemistry and unlock new opportunities for cost reductions through new cell design and manufacturing innovations. 24M’s platform is the most significant advancement in lithium-ion technology since its debut more than 20 years ago.
By Richard Martin for The MIT Technology Review: A group of Stanford researchers have come up with a nanoscale “designer carbon” material that can be adjusted to make energy storage devices, solar panels, and potentially carbon capture systems more powerful and efficient. The designer carbon that has reached the market in recent years shares the Swiss-cheese-like structure of activated carbon, enhancing its ability to catalyze certain chemical reactions and store electrical charges; but it’s “designed” in the sense that the chemical composition of the material, and the size of the pores, can be manipulated to fit specific uses. The designer carbon tested at Stanford is “both versatile and controllable,” according to Zhenan Bao, a professor of chemical engineering and the senior author of the study, which appeared in the latest issue of the journal ACS Central Science. “Producing high-surface-area carbons with controlled chemical composition and morphology is really challenging,” says Bao. Other methods currently available, she says, “are either quite expensive or they don’t offer control over the chemical structure and morphology.” Cont'd...
Mark Shwartz, Stanford Univ.: Stanford Univ. scientists have created a new carbon material that significantly boosts the performance of energy-storage technologies. Their results are featured in ACS Central Science. "We have developed a 'designer carbon' that is both versatile and controllable," said Zhenan Bao, the senior author of the study and a professor of chemical engineering at Stanford. "Our study shows that this material has exceptional energy-storage capacity, enabling unprecedented performance in lithium-sulfur batteries and supercapacitors." According to Bao, the new designer carbon represents a dramatic improvement over conventional activated carbon, an inexpensive material widely used in products ranging from water filters and air deodorizers to energy-storage devices. "A lot of cheap activated carbon is made from coconut shells," Bao said. "To activate the carbon, manufacturers burn the coconut at high temperatures and then chemically treat it." The activation process creates nanosized holes, or pores, that increase the surface area of the carbon, allowing it to catalyze more chemical reactions and store more electrical charges.
Jeremy Thomas for Inside Bay Area News: In a christening hailed as a key moment in the effort to harness the sun's energy to create fuel, Lawrence Berkeley Lab officials on Tuesday unveiled a $59 million Solar Energy Research Center. Named after former Energy Department Secretary and Lab Director Steven Chu, the 40,000-square-foot Chu Hall will be a place of world-changing research in producing cheaper, more efficient renewable energy to replace fossil fuels, said Chu, who was honored for inspiring the mission. "This is one of the most important problems that science, technology and innovation really need to solve," Chu said. "It's a very big deal. ... We simply need to save the world, and it's going to be science that's going to be at the heart of that solution." The facility will be home to the Berkeley hub of the Joint Center for Artificial Photosynthesis, a Department of Energy-funded collaboration led by the California Institute of Technology that is attempting to create solar fuel as plants do by using sunlight and other catalysts to split water into hydrogen and oxygen gas and convert carbon dioxide into liquid fuels such as methanol and ethanol. The byproduct of producing such a fuel would be oxygen.
Researchers at Finland’s Aalto University have achieved a record-breaking 22.1% efficiency for a nanostructured silicon, or black, solar cell. They accomplished this by overlaying a thin, passivating film on the nanostructures by a process known as atomic layer deposition, and by integrating all of the metal contacts on the cell’s back side. Perhaps the best part: Black solar cells work really well on cloudy days. “This is an advantage particularly in the north, where the sun shines from a low angle for a large part of the year,” said professor Hele Savin from Aalto University, who coordinated the study, in a statement. “We have demonstrated that in winter Helsinki, black cells generate considerably more electricity than traditional cells, even though both cells have identical efficiency values.” Using the aforementioned process, the team managed to beat their previous record by almost 4%, which is a stunning achievement. The new cells have a certified external quantum efficiency of 96% at 300nm wavelengths, which the team said shows that charged carrier surface recombination is no longer a problem — and that for the first time, the black silicon isn’t limiting energy conversion efficiency. And thanks to the inherent properties of black solar cells, they can capture solar radiation at low angles, generating more electricity over the full duration of a day as compared with traditional cells.

A road made of solar panel material is producing more energy than the creators expected. Engineers created a solar power bike path near Amsterdam that is over 200 feet long last year, and the road generated over 3,000kwh during the first six months, according to Al Jazeera, enough energy to power a house for a year. The company that created the road, SolaRoad, claims that means the road can produce 70kwh per square meter per year. The road is made of solar panels, glass, rubber and concrete. The road can either power street lamps or add power to the general grid. Over 150,000 cyclists have ridden on bike path without a problem since the project began. The path is made to be non-reflective and to prevent skidding. SolaRoad is still refining its materials to make them even more weather proof and efficient, and the company hopes to expand to larger areas in the future.
One of the fastest-growing areas of solar energy research is with materials called perovskites. These promising light harvesters could revolutionize the solar and electronics industries because they show potential to convert sunlight into electricity more efficiently and less expensively than today’s silicon-based semiconductors. These superefficient crystal structures have taken the scientific community by storm in the past few years because they can be processed very inexpensively and can be used in applications ranging from solar cells to light-emitting diodes (LEDs) found in phones and computer monitors. A new study published online April 30 in the journal Science by University of Washington and University of Oxford researchers demonstrates that perovskite materials, generally believed to be uniform in composition, actually contain flaws that can be engineered to improve solar devices even further.
