Lithium Coatings 1µm-25µm
Improving your battery design starts with Sheldahl's ThinFoil. ThinFoil provides pure lithium layers down to 1 µm thin. It can be coated onto metal foil or onto vacuum deposited metallic layers which have been coated onto thin plastic webs. This gives primary and secondary battery developers thinner layers of Lithium metal per unit area.
Sheldahl's ThinFoil product offering includes:
- Lithium X Copper X PET
Lithium X Copper Foil
Lithium X Separator Material
Copper X PET X Aluminum
The thin film coating process allows the composition of layers to vary in thickness. One material can be covered by another and the interface can be a graded composition of the two materials. A material can be turned into an alloy at its surface. Additionally, with narrow webs, the composition of materials can be varied across the web. This has proven useful in building webs with varying electrical conductivity in the cross-web direction.
Applications include: primary and secondary batteries.
