摘要: Abstract Li 3 V (2 − 2 x /3) Mg (PO 4 ) /C ( = 0, 0.15, 0.30, 0.45) composites have been synthesized by the sol–gel assisted solid state method, using adipic acid C 6 H 10 O (hexanedioic acid) as carbon source. The particle size of is ∼1 μm. During pyrolysis process, network structure formed. effect 2+ doped on electrochemical properties 2 positive materials has studied. 1.8 0.30 cathode Li-ion batteries, retention rate discharge capacity 91.4% (1 C) after 100 cycles. Compared with /C, shown enhanced and capability. long-term cycles ex situ XRD tests disclose that exhibits higher structural stability than undoped system.
