采用NaBH4溶液还原金属离子的化学方法制备了纳米(<；100 nm)Cu5Sn6粉末。与微米级的Cu6Sn5合金相比，纳米Cu6Sn5合金的容量保持率有了显著的提高。纳米Cu6Sn5合金在100次循环下的体积容量几乎是石墨理论容量的两倍。
Nano-scale (<100nm) Cu5Sn6powders were prepared by a chemical method that used a NaBH4solution to reduce the metal ions. A significant improvement in capacity retention was obtained in the nano-scale Cu6Sn5alloy, compared to the alloy having micron-sized particles. The volumetric capacity of the nano-scale Cu6Sn5alloy at 100 cycles was almost twice the theoretical capacity of graphite.
