The Relationship

Graphene nanosheets (GNS) with attached MnOx nanoparticles are studied in regard to their structure and morphology. The relationship between the lithium storage performances and GNS contents as well as manganese valency was investigated. Experimental results showed that the specimen with 44 wt% GNS and high content of MnO delivered high reversible capacity (over twice of that in graphitic carbon anode), good cycling stability (0.8% fading per cycle), and high rate capability (67% at the 800 mA/g), which are dramatically better than pure Mn3O4. The improvement is attributed to the presence of GNS which provides continuous networks for fast electronic conduction and mechanical flexibility for accommodating the large volume change. The MnOx/GNS hybrid material has the added advantages over pure GNS, benefiting from its lithium storage potential of around 0.5 V which not only ensures high rate capability but also reduces the risk of metallic lithium formation with its safety hazard.

Long Cycle Life

Nanocrystalline Li4Ti5O12 was synthesized by an in situ spray pyrolysis technique followed by heat treatment in N2 for short periods of time, resulting in self-contained carbon originating from the organic synthetic precursors. The excellent high rate capability and full battery tests indicate that this is a promising 4 anode candidate for high power lithium-ion batteries.
