Technology and R&D

Scientists at the United States Pacific Northwest National Laboratory have discovered a root cause of dendrite formation, which can cause battery failure and even fires in lithium-ion technology. With this new knowledge, the group is now working on electrolyte recipes that eliminate dendrite growth entirely.

Scientists at Singapore’s Agency for Science, Technology and Research have developed a new method to produce lithium-sulfur based cathodes which exhibit stable performance and high storage capacity over 200 cycles. According to the agency, this represents “a promising step towards the commercialization of lithium-sulfur batteries.”

The Chinese company has announced it has acquired intellectual property rights pertaining to various applications of gallium-doped silicon wafers in solar cell applications from Japanese company Shin-Etsu Chemical.

Scientists at Germany’s Karlsruhe Institute of Technology have developed a new class of electrolytes they say could bring calcium batteries – currently only a lab technology – a step closer to being a practical reality for energy storage.

The company launched a solid-state battery in August it claimed could recharge itself to some degree from electrons in the air. Now ConFlow is preparing to test its devices with the help of artificial intelligence-powered monitoring devices in the new year.

American John B. Goodenough, Brit Stanley Whittingham and Akira Yoshino, from Japan, will receive the Nobel Prize for Chemistry for developing the lithium-ion battery. A statement from the Royal Academy of Sciences of Sweden said the invention “laid the foundations of a society without wires and fossil fuels, and [they] are of great benefit to humanity”.

A group of scientists at Netherlands based research institute AMOLF have discovered a method for electrochemical printing at the nanoscale. With further optimizations, the group theorizes, the technique could allow for the development of new, three dimensional solar cells.

Scientists at the University of Texas at Dallas have made a discovery they say has “altered the understanding of the fundamental properties of perovskite crystals”. Their findings could improve understanding of defect formation in perovskites, leading to devices with enhanced performance and stability.

Researchers from Canada have unveiled a new germanium deposition process which is said to eliminate threading dislocations and be significantly cheaper than previous approaches. The scientists say their technique creates nanovoids on the surface of the germanium layer which can attract and annihilate undesirable dislocations.

A new study shows solar may help reduce water pumping costs in a desert oasis of Mauritania significantly while reducing water losses. Researchers claim PV water pumping may also help prevent desertification.
