Micro Reactor

Li3PO4 and Co3(PO[Formula: see text]8H2O precursors, precipitated within a micro reactor using ethyl alcohol as anti-solvent, are sintered to form nanosphere-like LiCoPO4. Even without carbon coating, the resulting sample with 2.1[Formula: see text]wt.% Li3PO4 existence presents surprisingly high initial discharge capacity (up to 164[Formula: see text]mAh/g and 787[Formula: see text]Wh/kg at 0.1C) and superior high rate performance (117[Formula: see text]mAh/g and 561[Formula: see text]Wh/kg at 5C).

High Rate Performance

Two kinds of carbon sources and their mixtures with different proportions were employed to prepare the LiFePO4/C composite material by high temperature solid state method. Precursor materials with different carbon sources were prepared by planetary ball-milling without dispersant. Results showed that the various precursors had different effect on the uniformity of the mixing and the crystallinity of the LiFePO4/C positive material. The mixed carbon sources had better effects on the performance of positive material. When the ratio of sucrose and citric acid was 1:3 (75% citric acid), the discharge capacity of LiFePO4/C composite material was 144.1 mAh/g at the discharge rate of 0.2C. Its high-rate performance was also better.

We develop a new aluminum graphite tri-ion (Li+/PF6−/BF4−) battery configuration (AGTIB) using an anion-hybridization strategy with fast diffusion kinetics. The AGTIB has a high rate performance with a 90.5 mA h g−1 capacity at 15C and good cycling stability for over 500 cycles at 5C.
