【 摘 要 】

An advanced lithium ion battery using nanostructured tin-carbon lithium alloying anode and high voltage LiNi0.5Mn0.5O4 spinel-type cathode is studied, with particular focus to the low temperature range. The stable behavior of the battery is assured by the use of an electrolyte media based on a LiPF6 salt dissolved in EC-DEC-DMC, i.e. a mixture particularly suitable for the low temperature application. Cycling tests, both in half cells and in full lithium ion battery using the Sn-C anode and the LiNi0.5Mn0.5O4 cathode, performed in a temperature range extending from room temperature to 30 degrees C, indicate that the electrode/electrolyte configuration here adopted may be suitable for effective application in the lithium ion battery field. The full cell, cycled at -5 degrees C, shows stable capacity of about 105 mAh g(-1) over more than 200 charge-discharge cycles that is a relevant performance considering the low temperature used for the study.
