Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. Thus, further research is required to find better sodium host materials. The sodium salt makes up the cathode; the anode is made up of phosphorous.

European automotive and automotive battery industries call for extension of the exemption of lead-based batteries from the EU ELV Directive

Green Car Congress

The EU must continue to allow the use of lead-based batteries in vehicles as they are essential for the needs of future generations of European cars, according to the automotive and automotive battery industries in Europe. Following the consultation the Commission is expected to release its opinion in the first half of 2015.

Antimony nanocrystals as high-capacity anode materials for both Li-ion and Na-ion batteries

Green Car Congress

Initial studies revealed that antimony could be suitable for both rechargeable lithium- and sodium-ion batteries because it is able to store both kinds of ions. Sodium is regarded as a possible low-cost alternative to lithium as it is much more naturally abundant and its reserves are more evenly distributed on Earth.

Swiss researchers devise simple procedure to enhance performance of conventional Li-ion batteries without changing chemistries

Green Car Congress

Materials researchers at the Swiss Paul Scherrer Institute PSI in Villigen and the ETH Zurich have developed a very simple and cost-effective procedure for significantly enhancing the performance of conventional Li-ion rechargeable batteries by improving only the design of the electrodes without changing the underlying materials chemistry.
