One-step thermolysis synthesis of two-dimensional ultrafine Fe 3 O 4 particles/carbon nanonetworks for high-performance lithium-ion batteries

To tackle the issue of inferior cycle stability and rate capability for Fe 3 O 4 anode materials in lithium ion batteries, ultrafine Fe 3 O 4 nanocrystals uniformly encapsulated in two-dimensional (2D) carbon nanonetworks have been fabricated through thermolysis of a simple, low-cost iron( iii ) ace...

description: To tackle the issue of inferior cycle stability and rate capability for Fe 3 O 4 anode materials in lithium ion batteries, ultrafine Fe 3 O 4 nanocrystals uniformly encapsulated in two-dimensional (2D) carbon nanonetworks have been fabricated through thermolysis of a simple, low-cost iron( iii ) acetylacetonate without any extra processes. Moreover, compared to the reported Fe 3 O 4 /carbon composites, the particle size of Fe 3 O 4 is controllable and held down to 3 nm. Benefitting from the synergistic effects of the excellent electroconductive carbon nanonetworks and uniform distribution of ultrafine Fe 3 O 4 particles, the prepared 2D Fe 3 O 4 /carbon nanonetwork anode exhibits high reversible capacity, excellent rate capability and superior cyclability. A high capacity of 1534 mA h g 1 is achieved at a 1 C rate and is maintained without decay up to 500 cycles (1 C = 1 A g 1 ). Even at the high current density of 5 C and 10 C, the 2D Fe 3 O 4 /carbon nanonetworks maintain a reversible capacity of 845 and 647 mA h g 1 after 500 discharge/charge cycles, respectively. In comparison with other reported Fe 3 O 4 -based anodes, the 2D Fe 3 O 4 /carbon nanonetwork electrode is one of the most attractive of those in energy storage applications.
