Lithium battery voltage
Lithium battery voltage is a measure of the battery
one of the most important indicators of performance, which represents the
lithium-ion battery positive and negative ends of the electric potential difference
in a certain state. Following small make up the following nouns explanation to
help you understand lithium battery voltage.
Nominal
voltage, also known as the rated voltage, voltage in the battery during normal
working process, lithium battery nominal voltage is 3.7V or 3.6V.
According
to the different cathode materials for lithium ion battery, nominal
voltage is different. Lithium cobalt oxide batteries nominal voltage of 3.7V,
lithium manganese batteries nominal voltage of 3.8V; Li-NI-co-MN ternary
materials of lithium-ion batteries nominal voltage only 5-3.6V. But with the
improvement of the formula and structure, the lithium battery nominal voltage
up to 3.7V; lithium iron phosphate battery nominal voltage minimum, only 3.2V,
But this is a great material for lithium-ion battery, do not explode cycle
performance is very good up to 2000 weeks.
Open
circuit voltage, refer to lithium-ion batteries in open circuit condition
(Non-working), Electrical potential difference between the anode and
cathode. Open circuit voltage of the lithium battery full status for4.2V and lithium battery manufacturer shipped voltage is set to 3.6~3.9V.
Operating
voltage, lithium battery connected load after when there is current flowing
through the circuit between the battery positive and negative electrical
potential difference, also known as voltage. Lithium-ion batteries after the
connected loads, because of the presence of ohm resistance and polarization
over potential, lithium battery voltage are lower than the open circuit
voltage.
Lithium
battery voltage when charging the rechargeable batteries, lithium-ion battery
charger output added to the ends of the battery voltage, that is 4.2V. We
select Li-battery charger when you need to pay attention to the output voltage
of the charger. Constant current charging mode is constant voltage.
The
advantages of lithium-ion batteries so that it is widely used or even replace
the nickel-metal hydroxide batteries. Single lithium battery voltage is 3.6V,
is the nickel-metal hydroxide batteries 3 times. Through the explanation of the
above terms, I believe that everyone has the lithium battery voltage with a
better understanding.
