　　1. Self discharge capacity

　　The self discharge capacity of primary battery is much lower than that of secondary battery. At the same time, it can only be discharged once, while the secondary battery can be discharged repeatedly.

　　2. Environmental protection

　　Environmental protection is the most important topic in recent years. The secondary battery is much better than the primary battery in this respect. The primary battery must be discarded after use, while the secondary battery can be reused. The second-generation secondary battery that meets the national standard can usually be reused more than 1000 times, which means that the waste generated by the rechargeable battery is less than 1/1000 of the primary battery. Whether from the perspective of waste reduction or from the perspective of resource utilization and economy, the advantages of the secondary battery are very obvious.

　　3. Internal resistance

　　The internal resistance of primary battery is far greater than that of secondary battery, and its high current discharge performance is also inferior to that of secondary battery.
