There’s been a lot of interest in Tesla’s 4680 batteries since before they were even announced, but their development and ramp-up have been a bit below par in terms of most people’s expectations. I’ve seen various claims about these, and those claims have diverged quite a bit as time has gone on, so it was […]
Modern EV Batteries Rarely Fail: Study
Plug-in electric vehicle’s lithium-ion batteries have become less prone to failures in recent years. According to Recurrent’s study entitled New Study: How Long Do Electric Car Batteries Last?, recently highlighted by the DOE’s Vehicle Technologies Office, significant progress has been made after the first several years of series EV production. The data from about 15,000 […]
Solar manufacturers petition U.S. to impose tariffs on imports from four Southeast Asian nations
A coalition of U.S. solar manufacturers on Wednesday petitioned the federal government to impose tariffs on imports from four Southeast Asian nations, alleging that the countries are flooding the U.S. market with cheap products that threaten the domestic industry. First Solar and six other manufacturers allege that companies in Cambodia, Malaysia, Thailand and Vietnam are dumping […]
BHP approaches rival Anglo American about takeover
BHP Group Ltd. has approached Anglo American Plc about buying the 107-year-old company in a move that offers to spark the biggest shakeup of the global mining industry in over a decade. Anglo American said late Wednesday that it received an unsolicited all-share merger proposal from the world’s biggest miner, after Bloomberg reported that BHP […]
Researchers propose a new method for wind turbine blade recycling
While wind energy is becoming one of the fastest-growing energy sources in the world, wind turbine blade waste emerges as a critical issue. Addressing this urgent environmental concern, Lithuanian researchers have developed an innovative solution, claiming that the benefits of pyrolysis can help reduce pollution. Wind turbine blades play a crucial role in harnessing renewable […]
Ion thermoelectric conversion devices for near room temperature
The electrode sheet of a thermoelectric device consists of ionic hydrogel, which is sandwiched between the electrodes to form, and the Prussian blue on the electrode undergoes a redox reaction to improve the energy density and power density of the ionic thermoelectric generator. New research on this topic appears in Energy Material Advances. Prof. Zeng Wei of the […]
An ultralow-concentration electrolyte for lithium-ion batteries
Lithium salts make batteries powerful but expensive. An ultralow-concentration electrolyte based on the lithium salt LiDFOB may be a more economical and more sustainable alternative. Cells using these electrolytes and conventional electrodes have been demonstrated to have high performance, as reported by a research team in the journal Angewandte Chemie International Edition. In addition, the […]
LME takes aim at traders’ Russian metal games with new rules
The London Metal Exchange is imposing new rules surrounding the movement of metal in its warehousing network, taking aim at a lucrative and complex trading opportunity that emerged after the imposition of sanctions on Russian metal earlier this month. The measures announced on Tuesday are designed to undercut the economic rationale for withdrawing Russian metal that’s already on […]
Plasma treatment enhances electrode material for fuel cells in industry, homes and vehicles
Researchers from Skoltech and their colleagues have improved the properties of a carbon-based electrode material by exposing it to air plasma. Such treatment turned out to enhance electrode performance, which is the limiting factor for high-tech energy sources—particularly fuel cells. These are a promising technology for cleaner and more efficient electrical power generation. Published in the Journal of […]
NSW battery materials company plans U.S. manufacturing plant
Wollongong-based Sicona Battery Technologies, which is developing a silicon composite material that improves the performance of batteries used for electric vehicles (EVs) and energy grids, announced it is moving forward with the development of a production plant in the southeast of the United States to take advantage of the booming battery and EV market. It […]
