Study on the effect of liquid nitrogen cold-quenching on electrochemical characteristic of TiO2 complex flakes with edged-curled derived from MAX as anode for lithium ion batteries

Progress on advancing technology of using liquid nitrogen for the non-polluting automobiles is reported. It is shown that the low exergy efficiency of the known engines fueled with liquid nitrogen has discredited the very idea of a cryomobile. The design of the open-cycle cryogenic Stirling engine is proposed. This engine allows extracting up to 57% of the exergy accumulated in liquid nitrogen. The method used to calculate of such open-cycle Stirling engine is described and the calculation results and discussion are presented. It is shown that 200 liters of liquid nitrogen is sufficient for 180 km range of cryomobile at speed of 55 km/h, while a full charge of the 300-kilogram battery of Nissan LEAF electric vehicle is sufficient for a range of 160 km. Use of liquid nitrogen or liquid air as an energy vector in a transport will not require scarce materials, and, in comparison with using of lithium-ion batteries or hydrogen, this will require less capital investment.

Based on the normal co-precipitation method to synthesize LiNi0.6Co0.2Mn0.2O2 cathode material, we propose a novel approach using a liquid nitrogen quenching method to synthesize Al2O3 coated LiNi0.6Co0.2Mn0.2O2 cathode material. In the whole process, liquid nitrogen was used four times to quench the materials from high temperatures (50 °C, 750 °C, 90 °C, 500 °C) to −196 °C rapidly in four stages. Various characterizations proved that this method could help to improve the electrochemical performance of lithium-ion batteries. Especially at 5 C rate current, after 100 cycles, the specific discharge capacities were 24.5 mAh/g (LNCM 622), 43.8 mAh/g (LNCM 622-LN), and 53.9 mAh/g (LNCM 622-LN@Al2O3). Liquid N2 quenching increased the charge/discharge capacities and the Al2O3 layer increased the cycle stability at high current, to finally obtain improved electrochemical properties.
