KERI researchers develop high-capacity Li-metal battery with improved rate performance and stability

Green Car Congress

A research team at Korea Electrotechnology Research Institute (KERI) has developed a high-capacity Li-metal battery with improved rate performance and stability using a one-dimensional Li-confinable porous hollow carbon host. The paper is published as a cover paper in ACS Nano.

Researchers at Korea University develop high-performance textile-based electrodes for watersplitting

Green Car Congress

An electrochemical water-splitting reaction offers an effective pathway to generate hydrogen fuels and store electricity from various intermittent but renewable energy sources. To address these problems, a carbonization/interfacial assembly-driven electroplating approach was applied to highly porous silk textiles. —Mo et al.

Nearly 20% of intact tropical forest landscapes overlap with extractive industries

Green Car Congress

Only 20% of tropical forests can be considered “intact,” but those areas store some 40% of the above-ground carbon found in all tropical forests. Intact forests are declining rapidly, with more than 7 percent of their total area lost between 2000 and 2013.

Rolls-Royce Power Systems road map for climate-neutrality; 35% cut by 2030 from 2019; key role of mtu engines

Green Car Congress

By 2030, the Rolls-Royce business unit is to cut greenhouse gas emissions by 35% compared to its 2019 level through the use of new net zero and zero carbon technologies. Rolls-Royce Power Systems has outlined its road map for climate neutrality: Net Zero@Power Systems. This is not yet relevant for Rolls-Royce applications.

U Chicago, MIT study suggests ongoing use of fossil fuels absent new carbon taxes

Green Car Congress

A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. We need both a policy like a carbon tax and to put more R&D money into renewables.

Constant Ratio Of Airborne To Absorbed CO2 In Carbon Cycle May Indicate Resilient Carbon Sinks

Green Car Congress

The analysis indicates that natural carbon sinks are maintaining overall resilience despite recent signs that the carbon uptakes of specific sinks are in decline. Approximately 40-45% of carbon emissions emitted every year remain in the atmosphere, with the balance absorbed as part of the Earth’s carbon cycle. per decade.

New stable Fe3O4/C composite material for conversion electrode in solid-state Li-ion batteries

Green Car Congress

In addition, recently a new chemistry has surfaced, allowing to store more Li + by the so-called conversion mechanism. The Fe 3 O 4 /C electrodes are characterized by galvanostatic cycling experiments using currents as high as 2000 mA g ?1 1 showed strong performance for more than 1000 cycles. … —Maroni et al.
