What are the major design considerations of lithium-ion batteries?

The major design considerations of lithium-ion batteries involve electrochemistry, thermal management and mechanical performance. The electrochemistry has been widely studied since it directly determines the battery performance and its life cycle. Different active materials on electrodes give different types of lithium-ion batteries.

Can a lithium-ion battery pack be vibration tested?

However, previous research acknowledges that different vibration tests proposed in standards and regulations for lithium-ion battery packs vary substantially in the levels of energy and frequency range (Kjell and Lang, 2014) so there is still a big challenge to emulate a test that represents the real working condition of electric vehicles.

How does compression affect the mechanical behavior of lithium rods?

The mechanical behavior of Li rods was characterized in compression as a function of sample aspect ratio, strain rate, and temperature. Additional compression experiments were performed with lithium foils of varying geometries at constant temperatures and strain rates.

Are vibration measurements based on a standard for lithium-ion batteries?

In conclusion, the comparison between the standards proposed for lithium-ion batteries varies substantially with respect to vibration measurements. These standards are derived from traditional internal combustion power trains (Kjell and Lang, 2014).

Can computational models be used to simulate lithium-ion battery cells?

The current study is focused on developing the computational models for simulations of RVE specimens of lithium-ion battery cells under in-plane constrained compression tests based on the work of Lai et al. and then comparing the computational results with those of the tests.

How does road roughness affect lithium-ion batteries?

For example, vibrations from road roughness, acceleration, and sudden collision considerably affect the mechanical properties and electrical performance of lithium-ion batteries (Zhang et al., 2017) as well as induce fatigue damage and functional disturbances (Kjell and Lang, 2014).
