“The main focus for tin is in the positive anode electrode of lithium ion batteries, usually made today
from graphite on a copper foil. Next generation products are already adding silicon into the graphite
to increase capacity. Some will probably use tin, either as an alternative or in addition to enhance
silicon performance. For example, China’s largest electric vehicle producer, BYD, recently patented
a tin-cobalt-carbon technology for anodes”
