  Elements that affect the life of lithium batteries

  1. The effect of operating voltage windows on the growth of the negative SEI film is that because of the wide electrochemical window, the dissolution of the transition metal elements is enhanced, and the dissolved transition metal element is migrated to the negative electrode appearance, which has accelerated the growth of the negative electrode transition metal film. The results showed that the conditions for negative electrode dynamics accelerated the decline of lithium, so the negative polarization precipitated lithium in advance, resulting in non -linear attenuation earlier.

  2. The effect of charge and discharge multiplied rate

  Because the non -linear attenuation of lithium ion batteries is mainly caused by the precipitation of the negative exterior lithium metal, the charging and discharge current is closely related to the non -linear attenuation of the lithium ion battery. The 1C -charging battery shows the trend of non -linear attenuation from the beginning, but if we reduce the charging current to 0.5C, the time node of the battery is a great delay in non -linear decay. The impact of the discharge current on the non -linear attenuation of the battery can be ignored. This is mainly because of the addition of the charging current, the polarization of the negative electrode is also obviously added, which causes the risk of lithium to be released from the negative electrode obviously added. The precipitated porous metal metal promotes the decomposition of electrolytes and accelerates. The decline in negative dynamic functions leads to the early stage of non -linear decay.

  3. The effect of temperature

  Temperature has a very important impact on the dynamic characteristics of negative electrode, so temperature also has an important impact on the time of battery non -linear attenuation.

  A non -linear decline in batteries in a 35 ° C cycle. If we reduce the battery voltage window to 3.17-4.11V, the battery attenuation rate of the 35 ° C and 50 ° C cycle in the early stage is relatively common, but at the end of the life of the life, the battery starts at 35 ° C has a non-linear decrease. This is mainly because the dynamic conditions of the battery worsen at low temperature, which causes the negative poles to be simpler as a lithium, which accelerates the growth of the membrane, leading to further deterioration of negative polar dynamics, leading to a decrease in non -linearity of the early lithium ion battery.
