New aqueous rechargeable lithium battery shows good safety, high reliability, high energy density and low cost; another post Li-ion alternative

Green Car Congress

Although several attempts have been made on the anode materials, the main disadvantages is that their energy density is still much lower than that of conventional lithium ion batteries due to the narrow electrochemical window of water. Here we introduce a coating layer on lithium metal. —Wang et al. —Wang et al.

Technical review outlines challenges for both batteries and fuel cells as basis for electric vehicles

Green Car Congress

Hydrogen produced via electrolysis using the EU mix or by natural gas reforming would exceed the target.). One open issue with silicon anodes in lithium-sulfur batteries is the incorporation of lithium by either industrially feasible pre-lithiation procedures or by the use of LiS- rather than S-cathodes.
