K value is in the lithium industry,K value refers to the battery voltage drop per unit time, usually expressed in mV\/d unit, is used to measure the self-discharge rate of lithium battery an indicator.
The constant current ratio of lithium batteries refers to the percentage of constant current charging in the total charging capacity, and the discharge platform generally refers to the percentage of the discharge capacity to 3.6V in the total discharge capacity. The charging process of the battery is generally the first constant current charging, in the constant current charging process, the voltage continues to rise, when the voltage reaches a certain set value, the charging is changed from constant current to constant voltage. This is also constant current constant voltage charging, constant current ratio is the ratio of constant current charging capacity to the total capacity of constant current and constant voltage charging
