Silica-based cathode enables long-life Li-S batteries

Green Car Congress

Scientists from the Daegu Gyeongbuk Institute of Science and Technology, Korea, have developed a novel silica-based cathode for lithiumsulfur batteries, thereby enabling the realization of batteries that can last for more than 2,000 charge/discharge cycles. Silica, a low-cost metal oxide, is actually non-conducting.

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

Green Car Congress

This will be followed by an assessment of the perceived technological barriers and the potential energy density gains for so-called post-LiBs, namely lithium-oxygen and lithium-sulfur batteries. For a 100 mile-range BEV requiring ≈21 kWh net , complete recharge could be accomplished within ≈60 min. Source: Gröger et al.
