UK EV battery research centre moves to latest cell size

UK electric vehicle battery research production line Amplifii has upgraded to accommodate 21700 Li-ion cells. These cells, 21mm diameter and 70mm long, are considered a better compromise between active electrode mass, passive structure mass and thermal performance than the common 18650 (18mm 65mm) size – Tesla is switching from 18650 to 21700. Amplifii (‘Automated module-to-pack ...

Carbon nitride grown as 2D semiconductor

Berlin researchers have have created a 2D semiconductor with an unusual property – it conducts better (65x better) perpendicular to is planes than along its planes – the opposite to graphene. It is called Triazine-based graphitic carbon nitride (TGCN), was created by Humboldt-Universität and the Helmholtz-Zentrum Berlin, and “should be highly suitable for applications in ...
