6 FAQs about [Lithium battery shock absorption mechanism]

What is the overall reaction of a lithium ion battery?

The overall reaction is the sum of these two half-reactions, representing the flow of lithium ions from the negative electrode to the positive electrode and the concurrent flow of electrons through the external circuit, thus releasing the stored energy from the battery.

What is the discharge process of a lithium-ion battery?

The discharge process of a lithium-ion battery is depicted in Fig. 1 (b). During this process, lithium ions are deintercalated from the negative electrode material (graphite) and migrate into the electrolyte. They then traverse the separator and return to the positive electrode (LiCoO 2).

Are lithium-ion batteries resilient against shock?

A first test series to investigate the resilience of lithium-ion batteries against shock and the relevant failure mode was performed by TÜV SÜD Battery Testing GmbH on a shock test machine. 2.1.

How does a lithium ion battery react with an electrolyte?

It is worth noting that during the first charge and discharge of lithium-ion batteries, the electrode material reacts with the electrolyte to form a passivation layer covering the surface of the electrode, known as SEI film .

How does thinning of lithium deposition affect the thermal stability of anode-electrolyte?

While in the subsequent process, the thinning of the lithium deposition layer on the anode surface and the improvement of the thermal stability of side reaction products causes the thermal stability of the anode-electrolyte to rise again, which is reflected in the rise of T 1 again.

What happens if a lithium separator is overcharged?

However, the elevated temperature makes the plated lithium react rapidly to form bulk lithium in the later stage of overcharge. Under the effect of elevated temperature, the separator shrinks, and part of pores are blocked by deposited substances. Those make the porosity of the separator gradually decrease with overcharging.
