Ultrathin transition metal silicate nanosheet cathode material for Li-ion batteries supports reversible two-lithium-ion capacity

Green Car Congress

The electrochemical performances of the samples were evaluated using a beaker-type three-electrode cell with metallic Li as a counter and reference electrode. For the study published in Nano Letters, they synthesized Li 2 MSiO 4 nanosheets by a rapid one-pot supercritical fluid reaction using a mixed solvent of aqueous ethanol. MWCNT coating.

Audi introducing electric 1+1 urban concept at Frankfurt with support for wireless charging; more detail on electric A2 concept

Green Car Congress

The outer skin of the show car is made of carbon fiber-reinforced polymer (CFRP); the occupant cell is a mix of CFRP monocoque and an aluminum structure. Audi Wireless Charging (AWC) refers to contactless induction charging. This ultra-lightweight construction is the foundation for the technology study’s low curb weight of 480 kg.
