| 1. | In the meantime , electrochemical properties of the materials in the organic electrolyte and aqueous electrolyte were researched 并探讨了其在水电解液和有机电解液中的电化学性能。 |
| 2. | The galvanostatic discharge curve of - mno2 in 5mol / l lino3 aqeous solution is similar to that in organic electrolyte , and the discharge mechanism is the homogeneous intercalation of li + ions - mno2在5mol / llino3中的放电曲线与在有机电液中的恒电流放电曲线类似,均为锂离子的均相嵌入机理。 |
| 3. | The mass specific capacitance of anthracite - based hsaac is smaller in organic electrolyte than that in aqueous electrolyte , because the diameter of solvated ions in the former is bigger and its electrical conductance smaller 量比电容。这一现象的产生与有机电解质溶液中溶剂化离子的直径较大、电导率;较低有关。 |
| 4. | However , the insulating nature of sulfur and polysulfides and the loss of polysulfides in the liquid organic electrolyte make lithium - sulfur batteries have very low positive active material utilization and poor cyclability 但是单质硫及其放电产物导电性差,易溶于有机溶剂,使得锂-硫电池正极活性物质利用率低、循环性能差等。 |
| 5. | Lithium - ion secondary battery duo to high specific energy and good cycle performance has attracted considerable attention , but its disadvantages of high cost and low safety can not been ignored by using organic electrolyte 锂离子电池以比能量高、循环性能好的优点得到了广泛关注,但因采用有机电解液,电池成本高,存在安全性差等不足。 |
| 6. | Sem and tem analysis show that the sample co - doped by nickel and titanium has nano - pellets with morpha like snow and great surface , which the initial discharge capacities in organic electrolyte reached 155 . 8mah / g and which were more than theoretic one farad electron discharge capacities ( 148mah / g ) . during the charging and discharging cycle , the change rate of the crystal volume was only 0 . 233 % and the sample showed long cycle life 样品在有机电解液的初始电容量( 155 . 8mah / g )大于理论1f电子放电容量( 148mah / g ) ,通过充放电前后xrd衍射图显示,放电前后晶胞体积变化仅为0 . 233 ,样品循环性能好。 |
