Battery cabinet load-bearing treatment

The integration of lithium-ion battery with composite laminate increased the energy absorption capacity by 57 %, attributed to its high deformability. The introduction of polymer foam significantly improved the energy absorption density while not affecting much the impact resistance.

The literature results lay a strong foundation for the safety design of lithium-ion batteries and related engineering systems. It was also suggested that among the three battery types, the thin-film Li-ion batteries have inferior mechanical properties and are prone to cracking at relatively low levels of deformation .

The integrated structure absorbs more energy at higher incident energies and undergoes greater deformation, leading to more severe soft circuit and electrical failures. The integration of lithium-ion battery with composite laminate increased the energy absorption capacity by 57 %, attributed to its high deformability.

Aluminum battery enclosures typically deliver a weight savings of 40% compared to an equivalent steel design. According to Asfeth, the alloys best suited for battery enclosures are the 6000-series Al-Si-Mg-Cu family — alloys that are also highly compatible with end-of-life recycling, he said.

The battery arrangement affects the load-deformation curves as the mechanical integrity in width and length direction is altered. Both Model W and Model L exhibit permanent plastic deformation at the end of impact events. Fig. 6.

The mechanical properties of lithium-ion batteries have been measured under various loading conditions, such as in-plane and out-of-plane compressions [6, 12, 18], punch indentation [19, 20], nail penetration [7, 21], bending [22, 23], tension, and impact events .
