This type of batteries is commonly referred to as “structural batteries”. Two general methods have been explored to develop structural batteries: (1) integrating batteries with light and strong external reinforcements, and (2) introducing multifunctional materials as battery components to make energy storage devices themselves structurally robust.
Pack design will be critical for future solid-state batteries Solid-state batteries are touted as the endgame for battery technology, boasting high energy density and improved safety. However, pack design will still be crucial to making them viable.
For structural batteries, the solid nature indicates that they can enhance not only the tensile and compressive properties of a battery, but also load-transfer between different layers and thus improve flexural properties.
The electric vehicle (EV) battery pack is a crucial component that stores and supplies energy to the vehicle's electric motor. The combination and design of battery pack components may vary depending on the specific electric vehicle model and manufacturer.
The most common configuration in hybrid battery packs includes a combination of Li-Ion batteries and Nickel-Metal Hydride batteries. Battery packs comprise smaller sections called battery modules (or sub-packs). These modules have fewer cells, which makes them safe to handle.
