The polyoxovanadate cluster Li7[V15O36(CO3)] is shown to be an active cathode material in Li-ion batteries, delivering a capacity of 250 mA h g(-1) at 50 mA g(-1) and 140 mA h g(-1) at 10 A g(-1). Li-ion diffusion is rapid in this material and gives rise to an impressive maximum power density output of 25.7 kW kg(-1) (55 kW L(-1)).
多酸簇合物 Li7[V15O36(CO3)] 被证明是锂离子电池中的一种活性阴极材料，在 50 mA g(-1) 和 10 A g(-1) 的电流密度下，其容量分别可达 250 mA h g(-1) 和 140 mA h g(-1)。在该材料中，锂离子扩散速度很快，产生了令人印象深刻的最大功率密度输出 25.7 kW kg(-1)（55 kW L(-1)）。
