Lithium-ion batteries (LIBs) have become a new research hotspot due to their high energy density and long service life. However, the temperature characteristics, especially the poor performance at low temperatures, have seriously limited their wider applications. In this report, the research progresses in the low temperature performance of LIBs are reviewed. The main existing limitations of LIBs at low temperatures were systematically analyzed, and followed by discussion on the recent improvements in low temperature performances by developing novel cathode, electrolyte, and anode materials. The developments for improving the low temperature performance of LIBs are prospected. The three most important factors …

Journal of Electrochemistry
Metal–organic framework(MOF) is a kind of novel electrode materials for lithium ion batteries. Here, a composite material Co3(HCOO)6@rGO was synthesized for the first time by in situ loading of Co3(HCOO)6 on rGO (reduced oxide graphene) through a solution chemistry method. As an anode material for lithium ion batteries, it exhibited an excellent cycle stability as well as a large reversible capacity of 926 mAh·g-1 at a current density of 500 mA·g-1 after 100 cycles within the voltage range of 0.02 ~ 3.0 V vs. Li/Li+ with a good rate capability. …
