Green NCAP LCA study shows detrimental climate and energy impact of increasing vehicle weight, including EVs

Green Car Congress

The results of the Life Cycle Assessment (LCA) of greenhouse gas emissions and primary energy demand of the cars tested by Green NCAP in 2022 show that the current and continuous trend towards larger and heavier cars, significantly increases the negative impact on climate and energy demand.

Roskill sees recovery in lithium industry, buoyed by demand from rechargeable battery applications

Green Car Congress

In its new Lithium Outlook to 2030 report, Roskill notes that the prolonged downward trend for lithium compound and mineral concentrate prices has caused a difficult environment for many lithium producers since 2018. In 2019, rechargeable batteries accounted for 54% of total lithium demand, almost entirely from Li-ion battery technologies.

More work reported on approaches to stabilizing lithium metal anodes for high energy rechargeable batteries

Green Car Congress

Metallic lithium, with a high theoretical capacity of ~3,860 mAh g -1 , is one of the most promising materials for anodes in next-generation high energy rechargeable battery systems for long-range electric vehicles. This is higher than the theoretical specific energy of of 609 Wh kg ?1 Earlier post.) 2014.08.011.

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

Green Car Congress

the key to addressing the low-temperature capacity loss lies in adjusting the surface electron configurations of the carbon anode to reinforce the coordinate interaction between the solvated Li + and adsorption sites for Li + desolvation and reduce the activation energy of the charge-transfer process.

Gravimetric Ragone plot comparing energy and power characteristics of CNF electrodes based on the pristine and discharged electrode weight with that of LiCoO 2. This translates to an energy enhancement ~4 times greater than the state-of-the-art lithium intercalation compounds such as LiCoO 2 (~600 W h kg electrode -1 , the researchers said.
