What is the difference between a lithium-ion battery and a battery

- Aug 22, 2019-

1. Charge and discharge.


Lithium battery has no memory effect; battery can be charged and discharged at any time, battery self-discharge is low, monthly self-discharge is less than 1%, battery can be stored for a long time; power is strong, can be quickly charged and discharged quickly, 20 minutes can be filled more than 80%, 15 minutes You can put the electricity out.


The battery has a memory effect and cannot be charged at any time for charging. There is a serious self-discharge phenomenon, and the battery is easily discarded when it is left for a while; the discharge rate is small, and it cannot be discharged for a long time.


2. Temperature tolerance.


The common lithium battery operating temperature is -20-60 degrees Celsius, but after generally lower than 0 °C, the performance of the lithium battery will decrease, and the discharge capacity will be correspondingly reduced. Therefore, the full operating temperature of the lithium battery performance is 0 to 40 °C. The temperature of lithium batteries required by some special environments varies, and some can even operate normally in an environment of hundreds of degrees Celsius. The operating temperature of the battery is generally required to be between 20 ° C and 25 ° C. When the temperature is lower than 15 ° C, the discharge capacity is decreased. When the temperature is lowered by 1 ° C, the capacity is decreased by 1%, and the temperature is too high (more than 30 ° C). Will be greatly shortened.


3, shaping difference


Polymer batteries can be thinned, arbitrarily aread, and arbitrarily shaped because their electrolytes can be solid-state colloidal rather than liquid, lithium batteries use electrolytes, and require a strong outer casing to hold the electrolyte as a secondary package. . Therefore, this also increases the weight of the lithium battery.
