LR03 alkaline battery

　　Several key factors affect the cycle characteristics of LR03 alkaline battery

　　First, environmental humidity.

　　Excessive water will cause adverse reactions of positive and negative active materials, destroy their structures, and thus harm the circulation system. In addition, too much water is also bad for the formation of the SEI film. However, despite the trace elements of water It is difficult to remove, but trace elements of water can ensure the performance of lithium batteries to a certain extent.

　　Second, positive and negative levels of compaction.

　　If the density of the positive and negative stages is too high, although it can increase the specific energy of the lithium battery, it will also reduce the circulation properties of the material to a certain extent. Theoretical analysis believes that the higher the density, it means damage to the structure of the material. The larger the size, the more the material structure is the basis for ensuring the recyclable use of lithium batteries.

　　The third is the objective reasons test.

　　External factors such as: battery charging rate during testing, cut-off voltage, battery charging cut-off current, overcharge and power loss during testing, temperature of the testing room, sudden interruption during testing, contact internal resistance between test case and lithium battery cell, etc. , will affect the circulatory system function test results to some extent.

　　Fourth, there are too many negative levels.

　　The reason why there is too much negativity is not only the first (second) irreversible volume and the high density of the coating, but also the impact of the circulation characteristics. For lithium cobalt oxide batteries plus high-purity graphite systems, the negativity It is common for high-purity graphite to become the "weak point" in the circulation process. If the negative polarity is too high and insufficient, the lithium battery may not develop lithium before circulation, but after countless cycles, it will become normal. The optical structure has changed greatly, and the lithium iron phosphate provided by the positive stage cannot be fully absorbed, resulting in lithium precipitation, resulting in premature volume reduction.
