However, the increase of battery pressure in the late stage is unfavorable to the battery cycle life. In this paper, the external pressure of the fixed-constrained battery in the later stage is about 2.7 times that of the initial pressure. After more than 3000 cycles, the battery capacity suddenly dropped.
Studies have shown that the introduction of external pressure can effectively reduce the “solid-solid” contact resistance and prolong the cycle life of the battery. At the same time, the application of external pressure on the electrode materials has dramatic multiple interdisciplinary consequences.
However, the constraint became rigid when the compression exceeded 0.2 mm. Compared to the k values of the batteries in groups (a) and (b), that of the batteries in group (c) was smaller, and the expansion and contraction of the springs during the charge-discharge process stabilized the mechanical pressure on the batteries.
The expansion and contraction of the anode and the irreversible growth of the SEI film during charge-discharge cycling result in pressure changes on fixed batteries. External pressure could improve the contact efficiency of the electrode material, and proper external pressure is beneficial for the cycle life of lithium-ion batteries.
External pressure could improve the contact efficiency of the electrode material, and proper external pressure is beneficial for the cycle life of lithium-ion batteries. The cycle life of lithium-ion battery in this paper could be extended by 400 charge-discharge cycles in the presence of an initial external pressure of 69 kPa.
Owing to the physical constraints of their external casings and the fact that they continuously undergo volume changes during charge-discharge cycling, batteries are subjected to changes in pressure. Setting the optimal initial pressure is important because it could affect the performance and cycle life of batteries [9-13].
