Study finds solid-state batteries could reduce the carbon footprint of an EV battery by up to 39%

Green Car Congress

Solid-state batteries could reduce the carbon footprint of electric vehicle batteries by up to 39%, according to a study commissioned by European environmental NGO Transport & Environment (T&E) from Minviro , a company specializing in raw material life-cycle analysis, which compared emerging solid-state technology to current battery chemistries.

Fraunhofer develops new dry-coating process for battery electrodes

Green Car Congress

This coating contains the active components that are responsible for storing energy. The active material, conductive carbon and binders are dispersed in a solvent to make a paste, which is initially applied to the metal foil to form a wet coating. It could equally be used on lithium-ion cells as on lithium-sulfur or sodium-ion cells.

Aqua Metals is building a more sustainable battery recycling ecosystem

Charged EVs

The two main processes for recycling lithium-ion batteries are pyrometallurgy and hydrometallurgy. Pyrometallurgy, which traditionally doesn’t recover carbon or lithium, seems likely to be phased out. There are currently two main processes for recycling lithium-ion batteries.

UT Dallas researchers use 2D MoS2 as protective layer for Li-metal anodes in Li-S batteries; extended cycle life

Green Car Congress

For a Li–S full-cell configuration, using the MoS 2 -coated Li as anode and a 3D carbon nanotube–sulfur cathode, they reported obtain a specific energy density of ~589?Wh?kg Jeongwoon Hwang, both of the Erik Jonsson School of Engineering and Computer Science, worked with other regional scientists to improve lithium-sulfur batteries.

Industry study finds lead-acid to remain most wide-spread automotive energy storage for foreseeable future; new chemistries continue to grow

Green Car Congress

Hybrid vehicles , including advanced micro-hybrid, mild-hybrid and full-hybrid vehicles rely on the battery to play a more active role, with the energy stored from braking used to boost the vehicle’s acceleration. In full-hybrid vehicles, the stored energy is also used for a certain range of electric driving.
