For the applications of aqueous Li-ion hybrid capacitors and Na-ion hybrid capacitors, potassium ions are pre-inserted into MnO<sub>2</sub> tunnel structure, the as-prepared K<sub>1.04</sub>Mn<sub>8</sub>O<sub>16</sub> materials consist of <a>nanoparticles</a> and nanorods were prepared by facile high-temperature solid-state reaction. <a></a>The as-prepared materials were well studied andthey show outstanding electrochemical behavior. We assembled hybrid supercapacitors with commercial activated carbon (YEC-8A) as anode and K<sub>1.04</sub>Mn<sub>8</sub>O<sub>16 </sub>as cathode. It has high energy densities and power densities. Li-ion capacitors reach a high energy density of 127.61 Wh kg<sup>-1 </sup>at the power density of 99.86 W kg<sup>-1</sup> and Na-ion capacitor obtains 170.96 Wh kg<sup>-1 </sup>at 133.79 W kg<sup>-1</sup>. In addition, the <a>hybrid supercapacitor</a>s demonstrate excellent cycling performance which maintain 97 % capacitance retention for Li-ion capacitor and 85 % for Na-ion capacitor after 10,000 cycles.

The Way

Li-ion power battery which has a broad prospect of application in many industry fields is a new type of high power battery. The formation-testing and sorting-packing are necessary processes in battery manufacture. Currently the process of formation almost takes the way of monomer battery, then sorting and packing by measuring the parameters of its internal resistance, voltage and capacity. The operation is complicated and the amount of data is huge. On account of the problem, we propose a new process of battery modularization. It can greatly reduce the workload of the parameter testing when using the optimized process. And batteries can get a good consistency, which is favor of sorting-packing and production automation.
