Abstract:
Lithium ion batteries containing fine, non-aggregated silicon particles have high initial voltage and exhibit good charge retention over large numbers of charge/discharge cycles when used with an electrolyte containing one or more amines, under conditions that silicon contained in the anode is only partially lithiated such that the ratio of Li:Si is less than or equal to 2.2:1.

Claim (Index 19):
The lithium ion battery of  claim 15 , wherein the electrolyte comprises one or more monoamines and/or one or more polyamines, where the monoamines are of the formula (I)\n NR 1 R 2 R 3 \u2003\u2003(I) in which\n R 1 , R 2 , R 3  are H or monovalent hydrocarbyl radicals which have 1 to 30 carbon atoms and may be substituted by one or more substituents selected from the group consisting of F\u2014, Cl\u2014 and \u2014OR 4 , and in which nonadjacent \u2014CH 2 \u2014 units are optionally replaced by units \u2014C(\u2550O)\u2014 and \u2014O\u2014, and \n R 4  is an alkyl radical having 1 to 10 carbon atoms; and\n polyamines are of the formula (II)\n R 5 2 N\u2014(CR 6 2 ) a \u2014(NR 7 \u2014(CR 6 2 ) b)c \u2014NR 5 2 \u2003\u2003(III) \n \n \n in which\n R 5 , R 6 , R 7  are H or hydrocarbyl radicals which have 1 to 18 carbon atoms and are optionally substituted by one or more substituents selected from the group consisting of F\u2014, Cl\u2014 and \u2014OH, and in which nonadjacent units are optionally replaced by units \u2014C(\u2550O)\u2014 and \u2014O\u2014, \n a, b are integers from 1 to 6, and \n c has the value of 0 or is an integer from 1 to 40.
