Lithium-ion. The nominal voltage of lithium-ion is 3.60V/cell. Some cell manufacturers mark their Li-ion as 3.70V/cell or higher. This offers a marketing advantage because the higher voltage boosts the watt-hours on paper (voltage multiplied by current equals watts). The 3.70V/cell rating also creates unfamiliar references of 11.1V and 14.8V when

Because lithium-ion batteries can have a variety of positive and negative electrode materials, the energy density and voltage vary accordingly. The open-circuit voltage is higher than in aqueous batteries (such as lead–acid, nickel–metal hydride and nickel–cadmium). Internal resistance increases with both cycling and age, although this depends strongly on the voltage and temperature the batteries are stored at. Rising internal resi
For example, in a lithium-ion battery, the nominal voltage is typically around 3.7V, representing the battery''s average operating voltage during discharge. This is the most important metric for determining compatibility with
Lithium battery capacity is typically measured in ampere-hours (Ah) or watt-hours (Wh), indicating the amount of charge it can hold. Common capacities vary based on application but range from small batteries at a few Ah to large storage batteries of several hundred Ah. What is the usable capacity of a lithium battery?
You need to know the current and the time to calculate the lithium-ion battery capacity. The current, usually measured in amperes (A) or milliamperes (mA), is the amount of electric charge that flows through the battery per unit of time. The time, usually measured in hours (h) or fractions of an hour, is the charge or discharge cycle duration.
Capacity can be referred as ‘ nominal capacity ’, which is measured under defined standard conditions (current rate, temperature, and end-of-discharge voltage) and is defined by the manufacturer and is typically printed on the name plate of the battery.
When the latter is expressed in hours, the typical unit for battery capacity is the Ampere-hour. The discharge capacity of a new battery (i.e., before the notable beginning of the battery degradation) is a function of the temperature and the discharge current profile.
where the term “maximum available capacity” refers to the amount of electric charge that a battery can store or provide under current operating conditions in its current aging state. Under this definition, the maximum available capacity is a physical quantity that varies with the state of the battery and the operating conditions.
Nominal Voltage It is the average voltage delivered by the cell during discharge. Lithium-ion cells don’t have a steady voltage profile. An LFP cell discharges from 3.60V – 3.65V (depends on the cell brand) to close to 3.2V and offers a flat voltage curve during discharge, and then goes all the way down to 2.5V.
