View more6 FAQs about [Single layer performance battery]
What is a single-layer pouch cell?
Instead, single-layer pouch cells provide a more similar format to those used in industry while not requiring large amounts of active material. Moreover, their assembly process allows for better positive/negative electrode alignment, allowing for assembly of single-layer pouch cells without negative electrode overhang.
Why is a single-layer pouch format cell better than a coin format cell?
For example, in some study, single-layer pouch format cell with very small electrode area may not show better data consistency than a group of coin format cell with error analysis, due to its more complicated fabrication process, as well as difficult pressure control.
Does external compression affect performance and ageing of NMC/graphite single-layer Li-ion pouch cells?
The effects of external compression on the performance and ageing of NMC (1/3)/Graphite single-layer Li-ion pouch cells are investigated using a spring-loaded fixture. The influence of pressure (0.66, 0.99, 1.32, and 1.98 MPa) on impedance is characterized in fresh cells that are subsequently cycled at the given pressure levels.
What is the size of a battery cell?
We are currently testing battery cells with commercial dimensions of 70 x 85mm but only as a single layer, i.e., one cathode, one solid-state separator, and one in-situ formed lithium-metal anode. As noted in our SEC filings, there is much work ahead of us.
What is a typical battery cycle life test?
For typical battery cycle life testing, many batteries are run at C/3 rates, which means the cells are charged in three hours and discharged in three hours. For our cycle life demonstration, we used more aggressive testing conditions of 1C: full charge and discharge of the cell in one hour each.
What is QuantumScape's battery technology?
Let’s start by reminding readers that QuantumScape’s battery technology is still in the development stage. We are currently testing battery cells with commercial dimensions of 70 x 85mm but only as a single layer, i.e., one cathode, one solid-state separator, and one in-situ formed lithium-metal anode.
