Tin The Forgotten EV Metal

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”

New Generation Rechargeable Battery Made With Tin

Researchers at Cornell University working on the next generation of rechargeable Li-ion batteries have shown that the addition of tin to lithium and sodium anodes not only protects the anodes but increases their charge carrying capability. Life for batteries with a tin-coated anode was shown to be 500 hours at a charge density of 3 milliamperes per square centimeter compared with 55 hours if the anode was unprotected.

Reduced shipments from Myanmar in January

China tin trade subdued in January

Latest official customs statistics released by China last week showed that the country’s tin ore and concentrate imports from Myanmar fell by 57% year-on-year to 31,359 tonnes (gross weight) in January, predominantly due an earlier Chinese Spring Festival holiday period than in recent years. Refined tin imports also fell 34% over the same period to 643 tonnes.

Top 10 Refined Tin Producers – 2016

The top 10 global producers of refined tin showed a 2.4% reduction in aggregate production in 2016 to 218,165t according to the International Tin Research Institute (ITRI). Their share of the global market also declined marginally from 67% in 2015 to 65% in 2016. The top 4 Chinese producers account for just over 50% of top 10 production and managed a 1% increase in 2016 with the help of imports from Myanmar covering a decline in domestic raw material supply.

Heemskirk Tin Ore Sorting Update

Stellar Resources Limited (ASX: SRZ, “Stellar” or the “Company”) is pleased to advise that it has completed an initial X-ray sorting test program using drill core from the Severn and Lower Queen Hill tin deposits.

TOMRA advised in its test report that sorting using a full size TOMRA COM XRT machine was “able to identify and separate high density tin bearing particles from waste. Different machine settings were used for each of the feed materials and both sets of samples showed significant amenability to upgrading the tin concentration.”
