Tin foil energy storage

Can tin foil be used in lithium ion batteries?

ITA Report on ‘Tin in Lithium-ion Batteries’ – Jan 2019 Tech startup, Nanode, has developed a low-cost tin foil anode technology for lithium-ion and sodium-ion batteries to increase volumetric energy density up to 50% while saving up to 60% on raw material costs and processing costs. Tin has a greater volumetric energy...

Could tin foils improve battery energy density?

Soc.168 120544 Electrochemical Society Fellow. Tin foils have an impressive lithium-storage capacity more than triple that of graphite anodes, and their adoption could facilitate a drastic improvement in battery energy density.

How efficient is tin foil?

Across the full 200 cycles, the tin foil stored a cumulative capacity of 17.92 Ah g −1 while returning 17.89 Ah g −1, representing a lifetime coulombic efficiency of 99.8%. This cumulative efficiency includes all formation and cycling losses and suggests electrochemical alloying and dealloying was remarkably efficient within this regime.

How is tin foil made?

The tin foil was synthesized as follows. Approximately 50 g of tin (Metal Shipper Inc., > 99.95%) was melted in air at 300 °C in a high temperature graphite crucible. The melt was then cast into a graphite mold, and a manual Durston rolling mill was used to process the tin ingot into a foil with a thickness of 20 microns.

How stable are foil anodes for high-energy-density batteries?

Interestingly, aluminum, tin, and indium offer not only high capacities but also display remarkable formation efficiencies ranging from 90 to 98%. The stability of each material was also benchmarked across a range of utilizations, laying the groundwork for future efforts in designing stable foil anodes for high-energy-density batteries.

Is tin foil better than microparticle anode?

Although the theoretical areal capacity of the tin foil was approximately 10x greater than that of the microparticle anode, the initial active material utilization was comparable between both electrodes.
