AbstractWe design a way that the anode hosts provide lithium ion in lithium ion battery operation. If the limiting factors of the cathode materials are less, there will be more alternatives for it. It was proven to be successful by two kinds of test cells based on LixCn as anode material, and β-FeOOH or Cr8O21 as cathode materials. Their theoretical capacities are much higher than those present electrode materials. Unlike the lithium secondary batteries with lithium metal foil or lithium alloy as anode, this type of lithium ion batteries with LixCn as anode prohibit dendrite formation during charging-discharge process. The idea of lithium ion sources coming from the anode can come true successfully as a result that steady protecting solution be sought for LixCn.

Enhanced Electrochemical Performance

Novelty Cu2O multi-branched nanowires and nanoparticles with size ranging from [Formula: see text]15[Formula: see text]nm to [Formula: see text]60[Formula: see text]nm have been synthesized by one-step hydrothermal process. These Cu2O nanostructures when used as anode materials for lithium-ion batteries exhibit the excellent electrochemical cycling stability and reduced polarization during the repeated charge/discharge process. The specific capacity of the Cu2O nanoparticles, multi-branched nanowires and microscale are maintained at 201.2[Formula: see text]mAh/g, 259.6[Formula: see text]mAh/g and 127.4[Formula: see text]mAh/g, respectively, under the current density of 0.1[Formula: see text]A/g after 50 cycles. The enhanced electrochemical performance of the Cu2O nanostructures compared with microscale counterpart can be attributed to the larger contact area between active Cu2O nanostructures/electrolyte interface, shorter diffusion length of Li[Formula: see text] within nanostructures and the improved stress release upon lithiation/delithiation.

Lifepo4 Cathode

Olivine compounds LiFePO4 were prepared by the solid state reaction, and the electrochemical properties were studied with the composite cathode of LiFePO4/mesocarbon nanobead. High discharge rate performance can be achieved with the designed composite cathode of LiFePO4/mesocarbon nanobead. According to the experiment results, batteries with the composite cathode deliver discharge capacity of 1087mAh for 18650 type cell at 20C discharge rate at room temperature. The analysis shows that the uniformity of mesocarbon nanobead around LiFePO4 can supply enough change for electron transporting, which can enhance the rate capability for LiFePO4 cathode lithium ion batteries. It is confirmed that lithium ion batteries with LiFePO4 as cathode are suitable to electric vehicle application.
