Lithium-ion battery discharge
Process equipment using lithium-ion batteries is lithium ion battery the discharge process. How to
discharge lithium batteries? All cases the working mechanism of lithium-ion
batteries are the same, that is, if there is an important difference in the
work environment, then, under the condition of non-conventional lithium-ion
batteries how to charge?
Lithium battery the discharge process is balanced at work, in
theory, lithium battery depth of discharge to note that discharge rates and
discharge.
Depth of discharge is discharge and the ratio of the nominal
capacity, the best practical reference is a voltage, lithium battery depth of
discharge to the discharge is more scientific? General criteria are: a the
battery to2.75Vand 3Vwill be able to charge the battery between, because less
than2.75Vtaboo is prone to charging batteries "discharge", when, from
the internal structure, may result in excessive volatile electrolytes, second,
the excessive reaction of lithium battery cathode membrane changes resulting in
decreased ability to block removal of their media to form a permanent loss of
capacity.
Another can effectively explain how lithium-ion batteries
discharge parameter is the discharge rate, discharge rate can be converted to
the current, for example, a 1800mAh Of batteries
0.1C rate of discharge, and the discharge current is 180mAh and discharge current are
typically small as well. So, in the battery, judging from the depth of
discharge, pay attention to nutritional supplements from the discharge current,
pay attention to long. Because no other secondary batteries of lithium battery memory effect, so don't care about
problems with activated battery lithium-ion battery to discharge.
When the lithium battery is idle, the actual discharge phenomena,
called self-discharge, then in the process of self-discharge, lithium-ion
battery to discharge it? Form there are two: one is negative that makes
lithium-ion embedded in the cathode, the dissolution of the second electrode,
on the lithium ions on the cathode reduction. These two forms have the
discharge process is reversible, self-discharge losses in most of the
lithium-ion battery capacity can be added by charging. Looked from the
discharge values change, how the li ion battery discharge? This lithium-ion batteries
the ambient temperature-related. In General, high temperatures (55℃)
monthly self discharge rate of 10%,
and lost only a month at room temperature 2~3% 。
In theory, lithium battery discharge point is to understand
effects of lithium battery discharge, but in practice, lithium-ion battery how
to discharge into the discharge time, discharge notes, specific action.
Strengthen the "lithium-ion battery discharge" both knowledge of and
longer battery use.
