Customer ServiceThe partial short circuit of the separator and the relaxation effect contribute to the impact failure. MI-PNGV model is proposed to simulate the failures under different extreme mechanical conditions. The design guideline is proposed to avoid the mechanic impact failure of lithium-ion batteries.
The cathode electrode determines the potential of the lithium-ion battery. Damage to the cathode material leads to a slightly lower battery potential upon full recharge after impact and causes partial capacity loss of the lithium-ion battery. 3.3. Discussion on the redundancy design of a Li-ion battery under high-dynamic impacts
(a) Schematic diagram of the impact process of lithium-ion batteries and (b) the relaxation phenomenon proposed by Fuller . With the discharge process of lithium-ion batteries, lithium ions are separated from the negative electrode, transported through the electrolyte and embedded in the positive material.
Xu et al. discussed the failure phenomenon of cylindrical lithium-ion batteries under bending loads, which was based on ISC, revealing that the mechanical failure behavior of lithium-ion batteries is highly dependent on the state of charge (SOC).
In the process of constant current discharge of lithium-ion batteries, due to the mixing mechanism of impact and vibration, the lithium ions in the electrolyte redistribute, and the voltage increases slowly. This process is similar to the relaxation phenomenon proposed by Thomas F. Fuller (Fig. 4 b).
With the advantage of high energy density, lithium batteries are widely used in industrial and military applications. However, under the complex conditions of vehicle collision and high-speed flight ammunition, lithium-ion batteries have functional failure, which seriously affects the safety and stability of systems using batteries.
