Yang N.-H.Wu Y.-S.Chou J.Wu H.-C.Wu N.-L.2019-05-172019-05-17201503787753https://scholars.lib.ntu.edu.tw/handle/123456789/409007Abstract A high-performance Si oxide-coated graphite flake (SGF) composite anode for Li-ion batteries (LIBs) is synthesized using a microwave-assisted coating method. In this synthesis, a solution comprising liquid polysiloxanes is used as the Si-containing precursor. Heating the graphite flakes (GFs) with microwave induces the deposition of a Si-containing conformal layer on the GF surfaces, which is subsequently calcined to produce SGFs. When tested as a LIB anode, the resulting SGF exhibits a reversible specific capacity of nearly 480 mAh g-1, 97% capacity retention at a current density of 2.5 A g-1 (approximately 5 C-rate), and 94% capacity retention after 500 cycles with an average Coulombic efficiency > 99.9%. The results suggest new strategies for both designing and synthesizing high-performance anode materials for LIB applications. ? 2015 Elsevier B.V.AnodeFast-chargingGraphiteLi-ion batteryMicrowave synthesisSilicon[SDGs]SDG7Anodes; Charging (batteries); Coatings; Electric batteries; Electrodes; Graphite; Ions; Lithium; Lithium alloys; Lithium compounds; Microwaves; Secondary batteries; Silicon; Silicon oxides; Silicones; Coulombic efficiency; Fast charging; High-performance anode materials; Li-ion batteries; Lithium-ion battery anodes; Microwave assisted; Microwave synthesis; Reversible specific capacity; Lithium-ion batteriesjournal article10.1016/j.jpowsour.2015.07.0662-s2.0-84938270125https://www.scopus.com/inward/record.uri?eid=2-s2.0-84938270125&doi=10.1016%2fj.jpowsour.2015.07.066&partnerID=40&md5=02f6ffbe9d3aba1b506030bb7720acdf
