The K value (also known as self-discharge rate or voltage decay rate) is a key parameter that measures the speed at which the voltage of a lithium battery drops when it is stationary. The lower the discharge current, i. The “K or C” index. . K value refers to the voltage drop of the battery in unit time, usually expressed in mV/d, and is an indicator to measure the self discharge rate of lithium battery. Low K-value cells are considered A-grade cells. An excellent way to determine the cell quality is by measuring its. . Batteries are the final commercial product that are delivered to customers and that require some data provided from the manufacturers to allow customers to evaluate the performance of different battery types in terms of capacity rating, allowable DOD, and temperature operating ranges.

What is k value of a lithium battery?
K value refers to the voltage drop of the battery in unit time, usually expressed in mV/d, and is an indicator to measure the self discharge rate of lithium battery. OCV1 is measured at time t1. Measure OCV2 at time t2. K=(OCV1-OCV2)/(t2-t1)。 The K value of the battery with good performance is generally less than 2mV/d or 0.08mV/h.
What does K or C mean in a battery?
The capacity (K or C value) of a battery depends on the current with which it's discharged. The lower the discharge current, i.e. the longer the discharge time, the greater the usable capacity. And vice versa, the greater the discharge current, the less the available capacity. The “K or C” index always indicates the discharge time in hours.
Why does a lithium ion battery have a k-value?
It is primarily attributed to irreversible chemical reactions occurring within the battery. The “ K-value” is a crucial parameter used to quantify the self-discharge rate of a lithium-ion battery. It represents the voltage drop per unit of time under specific conditions (e.g., high temperature or room temperature).
What are the parameters of a battery?
The first important parameters are the voltage and capacity ratings of the battery. Every battery comes with a certain voltage and capacity rating. As briefly discussed earlier, there are cells inside each battery that form the voltage level, and that battery rated voltage is the nominal voltage at which the battery is supposed to operate.
