求翻译：磷酸铁锂离子电池正是用磷酸铁锂代替上述的正极化合物而成为新型电池。其电化学性能：克容量>130mAh／g；电压2V-4.2V；循环100次容量衰减不大于5%；循环2000次容量保持率为80%以上 （2-3）是什么意思？

Iron phosphate lithium-ion battery is lithium iron phosphate instead of the cathode compound and a new battery. The electrochemical properties: g capacity 130mah g; voltage 2v-4.2v; 100 cycles the capacity fading of less than 5%; cycle 2,000 times the capacity retention rate of 80% (2-3)

iron phosphate lithium ion battery is a lithium iron phosphate instead of the positive compounds into a new battery. The electrochemical performance: > 130 G capacity mAh g; voltage 2 - 4.2 V V; cycle at 100 capacity decay to 5 per cent; cycle 2000 capacity at a rate of 80 per cent or more (2 - 3

Iron phosphate lithium-ion battery is replaced by lithium iron phosphate cathode compounds above and become a new type of battery. The electrochemical performance
