中文摘要：
用微波法合成了锂离子电池正极材料Li3V2（PO4）3。XRD、充放电和循环伏安测试表明：在900℃下恒温11min。合成的样品结晶度好、无杂相，0．2C时，使用该材料的电池首次循环的充、放电容量分别为177．1mAh／g和145．7mAh／g，循环50次后，放电客量为98mAh／g。当充电到4．9V时，Li3V2（PO4）3存在4个充电平台，且有较高的放电平台。
英文摘要：
Li-ion battery cathode material Li3V2（PO4）3 was synthesized by microwave method. The test results of XRD, chargedischarge and cycling voltammetry showed the sample synthesized at 900 ℃ constant temperature for 11 min had good and pure crystal. The initial charge capacity of a cell with the material was 177.1 mAh/g at 0.2 C, discharge capacity was 145.7 mAh/g, the discharge capacity was 98 mAh/g after 50 cycles. Li3V2（PO4）3 had four charge plateaus and a high discharge plateau when charged to 4.9 V.
