Lithium-silica nanosalt as a low-temperature electrolyte additive for lithium-ion batteries
Louis Hamenu,Hae Soo Lee,Mohammed Latifatu,Kwang Man Kim,박종욱,Yong Gu Baek,Jang Myoun Ko,Richard B. Kaner 한국물리학회 2016 Current Applied Physics Vol.16 No.6
A lithium-modified silica nanosalt (LieSiO2, coded Li202) of hydrophobic fumed silica (R202) is synthesized to use as an electrolyte additive for lithium-ion batteries (LIBs) under low temperature conditions. The synthesis method consists of reacting the silica nanoparticles with LiH and consequently quickly reacting the conjugate silicate ions with 1,3-propanesultone as a surface stabilizer. The obtained Li202 nanosalt (2.5 wt%) is added into an electrolyte solution of 1.0 M LiPF6 dissolved in ethylene carbonate/ propylene carbonate/ethylmethyl carbonate/diethyl carbonate (20:5:55:20 vol%) þ 2 wt% vinylene carbonate. The electrolyte solution including the Li202 nanosalt shows higher ionic conductivity and superior electrochemical stability over 5 V, which is due to the stabilized surface group. The high-rate capability at 20 C of the LiCoO2/graphite cell is particularly enhanced by adding Li202 nanosalt. In addition, excellent cycle performance at 20 C endorses the use of Li202 nanosalt as a low-temperature electrolyte additive for LIBs.

The obtained Li202 nanosalt (2.5 wt%) is added into an electrolyte solution of 1.0 M LiPF6 dissolved in ethylene carbonate/propylene carbonate/ethylmethyl carbonate/diethyl carbonate (20:5:55:20 vol%) + 2 wt% vinylene carbonate. The electrolyte solution including the Li202 nanosalt shows higher ionic conductivity and superior electrochemical stability over 5 V, which is due to the stabilized surface group. The high-rate capability at -20 degrees C of the LiCoO2/graphite cell is particularly enhanced by adding Li202 nanosalt. In addition, excellent cycle performance at -20 degrees C endorses the use of Li202 nanosalt as a low-temperature electrolyte additive for LIBs. (C) 2016 Elsevier B.V. All rights reserved.</P>
