Researchers use carbon-based anodes with “bumpy” surfaces for Li-ion batteries that last longer in extreme cold

Green Car Congress

In comparison, lithium-ion batteries made with other carbon-based anodes, including graphite and carbon nanotubes, held almost no charge at freezing temperatures. 35 °C, the reversible capacity is still effectively retained at 160 mAh g –1 after 200 cycles. An open-access paper on the work is published in ACS Central Science.

The U.S.-China Chip Ban, Explained

Cars That Think

China has yet to respond—but Beijing has multiple options in their arsenal. Nvidia’s A100 , for comparison, is capable of over 600 teraflops and matches the 600 Gbps interconnect speed. Nvidia has already responded by introducing a China-specific chip, the A800, which appears to be a modified A100 cut down to meet the requirements.

New inventory of black carbon emissions from China finds 2007 levels higher than previously reported

Green Car Congress

BC emission map of China at 0.1° × 0.1° East and West China are separated by a dashed line from Qiqihar, Yinchuan, to Kunming. A new black carbon (BC) emissions inventory from China found BC emissions levels in 2007 of 1,957 Gg BC—higher than reported in earlier studies. for year 2007. Major emission areas are marked.

Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

In February 2012, the China State Council approved its first national ambient air quality standard for PM 2.5 , which will come into effect by the end of 2015. Since substantial coal use (equivalent to 50% of global coal consumption) is the primary reason for the poor air quality, China is considering setting a cap on its use.

Tsinghua study concludes existing regulations for diesel trucks and buses insufficient to reach NOx reduction target by 2015

Green Car Congress

According to report from a team at Tsinghua University, recently published by the the International Council on Clean Transportation (ICCT), real-world emission factors of CO, HC, and PM from diesel trucks and buses in China have been reduced significantly as emission standards have become more stringent from Euro 0 to Euro III.

Global Carbon Project: Global carbon emissions growth slows, but hits record high

Green Car Congress

Driven by rising natural gas and oil consumption, levels of CO 2 are expected to hit 37 billion metric tons this year, according to new estimates from the Global Carbon Project (GCP), an initiative led by Stanford University scientist Rob Jackson. and China account for more than half of all carbon dioxide emissions globally.
