New stable Fe3O4/C composite material for conversion electrode in solid-state Li-ion batteries

Green Car Congress

In addition, recently a new chemistry has surfaced, allowing to store more Li + by the so-called conversion mechanism. Fe 3 O 4 , also known as magnetite, is a low cost, environmentally benign metal oxide that can undertake a reversible conversion reaction with Li + ions … which results in a theoretical capacity of 924 mAhg ?1

DOE issues FOA for up to $4M for development of advanced H2 storage systems and materials

Green Car Congress

Most of the hydrogen that is used today is stored as a compressed gas (with pressures typically ranging from 150 to 700 bar) or a liquid (liquid storage requires cryogenic temperatures near 20 K). Three overarching performance targets for onboard hydrogen storage systems are: gravimetric capacity; volumetric capacity; and system cost.

DOE to award up to $184M for advanced vehicle research and development in 8 areas of interest

Green Car Congress

Such fuels should be currently available, or have the potential to become, commercially practical within the next 10 years. The objective of this AOI is to accelerate the realization of lighter weight vehicle materials made from magnesium and carbon fiber capable of attaining 50% weight reduction of passenger vehicles.
