Economical production of various battery cell formats made of different materials in small to medium batch sizes is rarely possible using today's stacking processes. A new approach integrates previously discrete steps in manufacturing to form a continuous, fully automated and therefore flexible stacking process in terms of material and format.
Ex-situ analysis of the electrode stacks before and after cycling suggest that cycling does not induce significant changes to the electrode stack structure and is consistent with good cycling behavior, even at 55 °C. The results suggest that the use of layered stack electrodes is a promising alternative for the preparation of lithium ion batteries.
Anode and cathode half stacks are made using a new process and the electrodes have been investigated in coin cells. Each half stack consists of a current collector, electrode, and separator combined into a single component.
Preparation for SEM The electrode stacks were imaged using cross sectional SEM with fresh electrode stacks and electrode stacks cycled in graphite/NMC cells. The fresh samples were prepared by cutting a piece of a small part of the electrode with a razor blade with the separator side facing the blade.
The electrode stacks were cut to a diameter of 14.7 mm and assembled in a coin cell using 40 μL of electrolyte (1 M LiPF6in 1:1:1 ethylene carbonate/dimethyl carbonate/diethyl carbonate (EC/DMC/DEC) ) and a protective polyolefin separator ring with an inner diameter of 12 mm and an outer diameter of 19 mm.
Coin cells were prepared and cycled with novel stacked anodes and cathodes. Cells with novel stacked electrodes had similar cycling performance to traditionally prepared lithium ion cells. SEM images suggest that the novel stacked electrodes have good stability after cycling. Abstract
