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.
