Battery casings are essential components in all types of lithium and lithium-ion batteries (LIBs) and typically consist of nickel-coated steel hard casings for 18650 and 21700 cell formats. These steel casings comprise over one quarter of total battery cell mass and do not actively contribute to battery capacity.
These steel casings comprise over one quarter of total battery cell mass and do not actively contribute to battery capacity. It is therefore possible to achieve considerable battery performance improvements, in terms of device energy density, by reducing the mass of the battery casing.
Lightweight Al hard casings have presented a possible solution to help address weight sensitive applications of lithium-ion batteries that require high power (or high energy). The approaches herein are battery materials agnostic and can be applied to different cell geometries to help fast-track battery performance improvements. 1. Introduction
The aluminium casings could readily be incorporated into standard commercial LIB manufacturing process with minimal process changes and provided a > 25 % boost to energy density. Crucially, stress testing of the cells revealed no added safety challenges associated with the material change.
Stress & abuse testing of the cells revealed no compromise of cell safety. Battery casings are essential components in all types of lithium and lithium-ion batteries (LIBs) and typically consist of nickel-coated steel hard casings for 18650 and 21700 cell formats.
Funding has enabled Prof. Low to initiate a research group and establish programmes from electrode to cell testing and recycling of lithium-ion batteries, as both Assistant Professor (2013) and Associate Professor (2019) in WMG, University of Warwick, United Kingdom.
