ASU team develops new solution for mitigating Li dendrite growth by tackling plating-induced residual stress

Green Car Congress

Now, researchers at Arizona State University, with colleagues at Rice University, have used a 3-dimensional layer of Polydimethylsiloxane (PDMS), or silicone, as the substrate of lithium metal anode to mitigate dendrite formation. Envision sugar cubes that contain a lot of small internal pores. Finally, lithium fills the pores.

Systematic review of EV battery pack costs suggests economies of scale may push cost toward US$200/kWh without further cell chemistry improvements

Green Car Congress

The key difference in design and cost between BEVs and internal combustion vehicles is the power train—in particular, the battery. It is commonly understood that the cost of battery packs needs to fall to below US$150 per kWh in order for BEVs to become cost-competitive on par with internal combustion vehicles.
