6 FAQs about [Lithium battery positive and negative electrode material heater]

Why do lithium ions flow from a negative electrode to a positive electrode?

Since lithium is more weakly bonded in the negative than in the positive electrode, lithium ions flow from the negative to the positive electrode, via the electrolyte (most commonly LiPF6 in an organic, carbonate-based solvent20).

Why does lithium ion deficiency affect battery heat generation?

It is difficult for lithium-ions to diffuse to the particle surface and react with the electrolyte at subzero temperature. As a result, the SOC on the NE surface decreases rapidly, causing the deficiency of lithium-ions and increasing the resistance and thus the battery heat generation significantly.

What is the polarization heat of NE & PE battery?

It is noted that the polarization heat of the NE and PE is much higher than the ohmic heat throughout the temperature range. At the subzero temperature of −15 °C, the battery still functions at low to moderate discharge rates of 1– 1.5C by experiencing a voltage rebound without significant losing in capacity.
