Ni3Sn4金属间化合物电极制备成革命性的纳米结构。描述了通过在纳米结构的Cu基底上电沉积获得的纳米结构的Cu基底。这种结构控制伴随电化学过程的体积应力，产生用锂金属存储电极很少观察到的性能。新电极显示出令人印象深刻的电化学行为，在锂电池中循环超过200次（图中显示了循环后的电极），具有稳定的高容量。
Ni3Sn4 intermetallic electrodes prepared into a revolutionary nanostructure. obtained by electrodeposition on a nanoarchitectured Cu substrate, are described. This structure controls the volume stress that accompanies the electrochemical process yielding a performance rarely observed with lithium metal storage electrodes. The new electrode shows impressive electrochemical behavior and cycles in lithium cells for more than 200 cycles (figure shows electrode after cycling) with a stable high capacity.
