New ceramics for domestic and cryogenic magnetic refrigeration

A continuously growing energy demand worldwide intensifies the need for development of new, high-performance energy conversion and storage technologies. A large part of energy consumption is due to cooling in the industrial sectors such as food conservation as well as air-conditioning for housing, buildings and vehicles. Hence, refrigeration appears as a major concern for the future involving both energy consumption and impact on the environment. To date, the energy for refrigeration comes primarily from fossil fuels which produce CO2, and it uses HFCs (hydrofluorocarbon type) gases for the classical gas-compression cycle. Both these gases pollute the environment. From this point of view, cooling based on using magnetocaloric ceramic oxides as the refrigerant material appears as a promising alternative. Full text.

Lithium-ion diffusion pathways within new battery-cathode materials

Li-ion batteries form a basic component on which our world of mobile electronics and communication is built. And they are increasingly used in high power applications such as electric vehicles and the storage of electricity from solar and other renewable power sources. In these batteries, the cathode is a lithium-containing compound. During a battery’s charging and discharging, Li+ ions are alternately extracted from and reinserted in the cathode as they move through the electrolyte to the anode and back. The cathode material must sustain wide variations of its Li+ ion content over many cycles. Full text.
