| Work Detail |
The energy density of the newly developed lithium-sulfur prototype far exceeds that of common lithium-ion batteries.
Chinese company General New Energy (GNE) has just announced a major breakthrough in lithium-sulfur (Li-S) battery technology, presenting a prototype with an energy density of 700 Wh/kg.
According to GNE, this new battery not only far exceeds the energy density of current lithium-ion batteries, but also offers substantial improvements in both mileage and safety.
Lithium-sulfur batteries, which use sulfur as the cathode and lithium metal as the anode, represent a promising alternative to traditional lithium-ion batteries. In theory, lithium-sulfur batteries can achieve energy densities of up to 2,600 Wh/kg, which is more than five times that of their lithium-ion counterparts. In addition, sulfur is abundant, inexpensive, and environmentally friendly, giving lithium-sulfur batteries a cost and sustainability advantage. |
