Abstract

The invention discloses a method for producing lithium titanate by a high-temperature melting method, which comprises the following steps of: uniformly mixing lithium hydroxide and anatase type titanium dioxide in a molar ratio of 4: 5, or uniformly mixing lithium carbonate and anatase type titanium dioxide in a molar ratio of 2: 5; pouring the materials into a high-temperature reaction container, vacuumizing a reaction cavity of the high-temperature reaction container to the air pressure of 5-10 Pa, starting heating, and maintaining liquid-phase reaction of the materials in the high-temperature reaction container at the temperature of 1650-1750 DEG C for 1-2 hours; pumping out the reaction gas generated in the heating process by a vacuum pump, and maintaining the air pressure in the reaction cavity at 5-10 Pa; and after the reaction is finished, pouring a lithium titanate melt generated by the reaction into a cooling mold through a tilting furnace, standing and cooling, taking out a lithium titanate solid, crushing the solid, and carrying out packaging; The method is short in liquid phase reaction time, few in process links, relatively low in cost, thorough in product synthesis reaction and relatively high in purity of the generated lithium titanate.

Description

technical field [0001] The invention relates to a method for producing lithium titanate, in particular to a method for producing lithium titanate by high-temperature melting. Background technique [0002] The lithium titanate negative electrode battery has a cycle life of up to 20,000 times. As an energy storage battery, the current energy storage cost of the lithium titanate battery is 5,000 yuan / kWh. With further cost reduction, energy storage costs can be reduced by 3,000 yuan / kWh. Based on the cycle life of 20,000 times, it can work for 60 years (charge and discharge once a day), and the average depreciation cost is 0.15 yuan / kWh. In addition, the current cost of photovoltaic power generation is 0.1 yuan / kWh, and the cost of photovoltaic power generation for full-day power supply is lower than 0.3 yuan / kWh. At present, the power generation cost of coal-fired thermal power generating units is about 0.4 yuan / kWh. Therefore, lithium titanate batteries have advantages as ...
