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 21):
The lithium ion battery of  claim 17 , 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(II) \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 \u2014CH 2 \u2014 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.
