Sustainable high-voltage lithium ion polymer batteries
No full textNew types of polymer lithium ion batteries, formed by combining a Li 4Ti 5O 12 anode with a LiMn 2O 4 and a LiNi 0.5Mn 1.5O 4 cathode, respectively, in a poly(vinylidene fluoride) PVdF-based gel electrolyte cell, are presented and discussed. The operating voltage is around 2.5 V for the battery based on LiMn 2O 4 and around 3.0 V for that based on LiNi 0.5Mn 1.5O 4. The electrochemical characterization demonstrates that these high-voltage batteries are capable of delivering appreciable capacity values at various rates, this being accompanied by a remarkable cycle life. In addition, since the two electrodes are based on common and not toxic materials and operate within the stability window of the electrolyte, the batteries are expected to be safe, inexpensive, and compatible with the environment. All these properties make the batteries of interest for application in the hybrid and electric vehicle field. © 2005 The Electrochemical Society. All rights reserved

No full textSolid-state, Ag/Me4NIn (n = 5 or 9) batteries have been tested in terms of changes of open circuit voltage, internal resistance and constant-load discharge curves after a storage time of 33 years at 23 degrees C. The results are in agreement the original shelf life projections, this confirming that these solid-state batteries should survive 50 years storage at 20-25 degrees C, and still deliver 50-60% of the initial available energy. To our knowledge, such an exceptional shelf life is an unique feature in the battery scenario which gives to these solid-state systems a renewed interest as reliable, long-life reference systems.
