Wacker slashes profit forecast amid polysilicon price slump

German polysilicon producer Wacker Chemie AG has reduced its earnings expectations for 2019, citing low prices for polysilicon. The company blamed the polysilicon price slump on oversupply from competitors in China, which muted an expected price increase in the second half of 2019.

UK: Give more power to regulators, says report

A report published recently by the United Kingdom’s National Infrastructure Commission says that the UK’s regulatory system must “adapt to meet the demands of the future” by providing new powers for regulators to ensure utility investments in sustainable infrastructure. The report notes that without such powers, the country will be unlikely to meet its target of zero emissions by 2050.

A new battery mix to prevent dendrites

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.
