[资源] 【资源】Adv. Mater. PROGRESS REPORT: Beyond Intercalation-Based Li-Ion Batteries

ASSP
Despite the imminent commercial introduction of Li-ion batteries in electric
drive vehicles and their proposed use as enablers of smart grids based on
renewable energy technologies, an intensive quest for new electrode materials
that bring about improvements in energy density, cycle life, cost, and
safety is still underway. This Progress Report highlights the recent developments
and the future prospects of the use of phases that react through conversion
reactions as both positive and negative electrode materials in Li-ion
batteries. By moving beyond classical intercalation reactions, a variety of low
cost compounds with gravimetric specifi c capacities that are two-to-fi ve times
larger than those attained with currently used materials, such as graphite
and LiCoO 2 , can be achieved. Nonetheless, several factors currently handicap
the applicability of electrode materials entailing conversion reactions. These
factors, together with the scientifi c breakthroughs that are necessary to fully
assess the practicality of this concept, are reviewed in this report.
