New class of coordination polymers for high-performance Li-, Na- and K-ion storage

Green Car Congress

Researchers at the Université catholique de Louvain in Belgium have designed and synthesized a new class of electrically conducting anionic coordination polymers for all practically relevant alkali-cation storage. V in lithium-, sodium-, or potassium-based cells. V for Li-, Na- and K-ion batteries. Wang et al.

PATHION develops new LiRAP-based solid-state electrolytes for Li-sulfur and sodium-ion batteries

Green Car Congress

Supported by an ARPA-E grant, LiRAP has proven to be a safe alternative compared to the liquid electrolytes used in most of today’s lithium ion batteries. The LiRAP solid electrolytes conduct Li + ions well at high voltage and high current, providing much enhanced energy density and power capacity as well as safety. Braga, J.A.

Researchers show that layered calcium transition metal oxides can be promising cathode materials for Ca-ion batteries

Green Car Congress

Out of several candidates that could replace Li in rechargeable batteries, calcium (Ca) stands out as a promising metal. Not only is Ca 10,000 times more abundant than Li, but it can also yield—in theory—similar battery performance.

UK’s Network Rail developing a prototype battery-powered train; trying Li-ion and sodium-nickel batteries

Green Car Congress

Working closely with Derby-based train manufacturer Bombardier and operator Greater Anglia, the project will use one of the operator’s Class 379s as a test-bed to determine future battery requirements and what kind of train might be needed. The batteries will undergo many lab tests before being fitted to the train.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C. The high energy storage has stimulated a worldwide study of Li-air batteries. V was developed.

ANL team develops new class of Li- and Na- rechargeable batteries based on selenium and selenium-sulfur; greater volumetric energy densities than sulfur-based batteries

Green Car Congress

Cycling performance of Li/SeS 2 ?C, Researchers at Argonne National Laboratory have developed selenium and selenium–sulfur (Se x S y )-based cathode materials for a new class of room-temperature lithium and sodium batteries. Unlike the widely studied Li/S system, both Se and Se x S y can be cycled to high voltages (up to 4.6
