为了提供锂离子电池的替代电池技术，具有高理论容量和易于制备的多价金属离子电池已逐渐受到学术界和工业界的关注。在这项工作中，我们报告了铋离子电池（BIB）作为有前途的三价金属离子电池，仅次于已知的铝离子电池。我们的BIB成功地证明了在0.5和0.2 V的放电平稳状态下的电池性能。在电流密度为0.2 A g -1的情况下，重力容量为300 mAh g -1，重均约为0.25 g / g 。库仑效率达到98％。此外，在0.3 A g -1下经过100次循环后，获得了稳定的循环寿命，这进一步表明了其作为潜在的三价金属离子电池的适用性。

Bismuth Ion Battery – A New Member in Trivalent Battery Technology
To provide alternative battery technologies to lithium ion battery, multivalent metal ion batteries with their high theoretical capacities and ease of preparation have gradually gained attention from both academia and industries. In this work, we report bismuth ion battery (BIB) as a promising trivalent metal ion battery, next to the only known aluminum ion battery. Our BIB successfully demonstrates battery behavior with discharge plateaus at 0.5 and 0.2 V. Gravimetric capacity of 300 mAh g-1 at current density of 0.2 A g-1 was obtained with ca. 98 % coulombic efficiency. In addition, stable cyclic life was achieved after 100 cycles at 0.3 A g-1 which further suggests its suitability as potential trivalent metal ion battery.
