The power lithium-ion battery of new energy vehicles can be divided
into secondary batteries (including lead-acid batteries,
nickel-cadmium batteries, nickel-metal hydride batteries,
lithium-ion batteries) and fuel-powered lithium batteries.
We refine it, starting from the classification of lithium-ion
batteries, and introduce the mainstream technical routes of power
lithium-ion batteries in the current market.
How it works
First of all, to correct a concept, lithium-ion batteries are
usually divided into two categories according to the different
materials used in the positive and negative electrodes:
Lithium metal batteries, that is, batteries that use manganese
dioxide as the cathode material and lithium metal or its alloy
metal as the anode material; Lithium-ion batteries, using lithium
alloy metal oxide as the cathode material and graphite as the anode
material battery.
The lithium-ion battery is composed of four parts: the positive
electrode (containing lithium compound), the negative electrode
(carbon material), the electrolyte, and the separator.
When the battery is charged, the lithium atoms on the positive
electrode are ionized into lithium ions and electrons
(deintercalation), and the lithium ions move to the negative
electrode through the electrolyte to obtain electrons, which are
reduced to lithium atoms and embedded in the micropores of the
carbon layer (inserted);
When the battery is discharged, the lithium atoms embedded in the
carbon layer of the negative electrode lose their electrons
(de-inserted) and become lithium ions, which move back to the
positive electrode (embedding) through the electrolyte.
The charging and discharging process of lithium-ion batteries, that
is, the process of continuous intercalation and de-intercalation of
lithium ions between the positive and negative electrodes, is
accompanied by the intercalation and de-intercalation of equal
equivalent electrons. The higher the number of lithium ions, the
higher the charge-discharge capacity.
