Ternary lithium battery, also known as ternary lithium polymer, refers to a lithium battery with nickel-cobalt manganate or nickel-cobalt aluminate as the positive electrode material. Ternary lithium batteries are widely used in new energy vehicles due to their smaller size, higher capacity density, and low temperature resistance.
The
service life of the ternary lithium battery is calculated according to
the ratio of the capacity decay degree after use to a certain extent,
and it will be terminated directly until the capacity life is zero. The
industry algorithm is generally that the ternary lithium battery is
fully charged and then discharged once, which is called the cycle life.
The
theoretical life of a lithium battery is 1200 times that of full charge
and discharge, that is, the full cycle life. According to the frequency
of use, charge and discharge once every three days, charge and
discharge 120 times a year, and the service life of the ternary lithium
battery reaches about 10 years. In actual use, the battery life will be
affected by various factors such as the manufacturer's manufacturing
technology, battery management technology, external environment, driving
habits of the owner, charging method, etc., and the actual use shall
prevail.
At present, the
three-electric warranty of general car companies is 8 years and 120,000
kilometers, and some car companies also provide three-electric lifetime
warranty. If it is not an ordinary household scene, but is used for
business purposes, it will be difficult to use it for eight years. With
the development of battery technology, especially driven by new battery
materials, battery management technology, and battery structure
innovation, the performance of power batteries has become more durable and safer.
In
daily use, the maintenance of the ternary lithium battery is also
extremely important. When the remaining 20%-30% of the power is left, it
should be charged in time to avoid the battery from being
over-discharged. The ternary lithium battery is not required for
long-distance use. It is not recommended to fully charge it. It is
better to charge it to 90% or below. When fully charged, it is easy to
consume active materials under high voltage and shorten the battery
life.
In addition, the
battery is composed of multiple battery cells. Due to the inconsistency
in the production and electrochemical reactions of the battery cells, a
full charge may easily cause a cell to be overcharged, thereby affecting
the battery life.
