Researchers are relentlessly improving the power, life and safety of lithium-sulfur batteries, which are increasingly used as power sources for gadgets such as smart phones and notebook computers. Problems arise when unwanted reactions decompose the organic liquid electrolyte and foul the metallic lithium electrodes.

Scientists from the University of Rome have designed a novel way to construct a tin-sulfur-lithium-ion battery that has an energy density value of the order of 1000 kW h kg-1, which is five times higher than those of conventional batteries.

How does this electrochemical process work?

The new lithium-metal-free cell uses a cathode made from a carbon/lithium sulfide composite. At the cathode, lithium sulfide is split into elemental sulfur and lithium ions. The design novelty is to replace the organic electrolyte solution with a lithium-ion-containing liquid enclosed in a polyethylene oxide/lithium trifluoromethane sulfonate gel membrane. The polymer membrane prevents the liquid from decomposing.  The lithium ions migrate through the electrolyte membrane to a tin/carbon nanocomposite anode, where they take up electrons to become uncharged lithium atoms. These are then bound into an alloy by the tin nanoparticles, minimizing the dissolution of the electrode components.  This new battery provides sufficient energy density to be considered as a possible power source for electric vehicles.
