Why is the damage caused by low temperature to lithium batteries irreversible?

Charging or discharging at low temperatures has an irreversible effect on the battery, causing capacity to dive and serious safety risks. Long-term storage at -20℃ will also irreversibly damage the battery and reduce its capacity.

1: low temperature lithium-ion battery charging and discharging process:
lithium batteries are generally composed of ternary cells (NMC), lithium iron phosphate cells (LFP), or lithium titanate (LTO) cells composed of the positive electrode, the negative electrode is graphite (Gr). As external factors reduce the activity of lithium ions, slow down the reaction rate, and slow down the transport process, a large amount of lithium accumulates at the interface between the electrode and the electrolyte. When charging, lithium ions can not be squeezed into the graphite layer will be directly on the surface of the negative electrode to get electrons into lithium metal, accumulation of lithium dendrites. When discharging, lithium ions are squeezed on the surface of the positive lattice, which is easy to cause the rupture of the positive electrode.

2, low-temperature charging leads to lithium precipitation, resulting in serious safety hazards:
when charging, lithium ions enter the graphite to directly undergo an intercalation reaction. At that time, the low temperature lithium ions can not enter the graphite layer directly in the negative electrode to generate lithium metal to complete the reaction, can not deep reaction, trip crystallization buildup, then the generated material is not reversible, resulting in capacity loss. In addition, the continuous growth of lithium metal makes it easy to puncture the diaphragm connected to the positive pole, resulting in an internal short circuit, which is prone to serious safety accidents.

3、Low temperature discharge induces the rupture of anode particles:
when discharging at low temperatures, lithium ions are squeezed on the surface of the anode lattice, which in turn is easy to cause the rupture of the anode active particles. On the one hand, it leads to the loss of anode active material, resulting in capacity loss. In addition, the precipitation of the transition metal elements of the positive electrode will migrate to the surface of the negative electrode and turn into metal particles, inducing the occurrence of lithium deposition.

4, low-temperature placement reduces battery capacity:
The battery is only placed at a low temperature for 48h, after which it is continued to be placed at room temperature for static storage, followed by capacity testing. When the battery is placed at a low temperature for a long period, the capacity will be lost by 3.2% when charging and discharging at a small rate (slow charging), but the capacity will be lost by 6% when charging and discharging at a large rate (fast charging).
low-temperature placement reduces battery capacity
The reason for the capacity loss under low temperature placement is that
The reason for the capacity loss under low temperature placement is that
(1) the low temperature exacerbates the rupture of the positive electrode. (2) Low temperatures may cause rotation of the anode particles, which allows them to detach from the binder and lose electrochemical activity.

What is the difference between low temperature lithium battery and ordinary lithium battery?
  1. Different application areas
    Cryogenic lithium batteries are mainly used in military aerospace, vehicle-mounted equipment, scientific research and rescue, electric power communications, public safety, medical electronics, railroads, ships, robots, and other fields.
    Ordinary batteries are not only applicable to power batteries (forklift, marine), automobiles, bicycles, semiconductor radios, recorders, cameras, electronic clocks, toys, etc.
  2. Difference in use environment
    Low temperature lithium batteries -50 ℃ can still be used normally
    Ordinary batteries can’t be used at -20℃ for general civil batteries.
  3. Difference in discharge capacity
    Low temperature battery discharged at -40℃ with 0.5C, the discharge capacity is more than 70% of the initial capacity.
    Ordinary batteries can only reach about 25% of the discharge capacity under low temperature environment.
