Intermetallic M-Sn5 (M=Fe, Cu, Co, Ni) Compounds

Among electrode materials for lithium ion batteries, tin offers a high theoretical capacity about 2.5 times that of graphite by weight. Unfortunately, when lithium alloys with tin the matrix undergoes a very large volume change. This change in volume results in a loss of capacity over a few charge-discharge cycles. By adding a transition metal to the tin, this volume change can be mitigated. The novel phase of FeSn5 or CoSn5 exhibits a capacity nearly twice that of FeSn2, the previous... read more

Although the polyolefin polymer material often used for lithium battery separators costs approximately $1.30/kg, the difficult process used to make it porous, to allow the flow of ions and electrons, raises its cost by two-orders of magnitude, to $120–$240/kg. A Berkeley Lab team led by Nitash Balsara has developed an inexpensive and easily controlled process yielding a nanoporous polymer separator that performs just as well as those made by conventional means.
