Where is the market for lithium titanate batteries?

Lithium titanate battery: high safety and low energy density. At present, ternary lithium and lithium iron phosphate batteries have accounted for more than 90% of my country's power lithium-ion battery industry. As an emerging power lithium-ion battery manufacturer, Guochuangcheng has withdrawn from the mainstream market and instead focuses on lithium titanate batteries. Of course, this is because your lithium titanate battery has comparative advantages. First of all, compared with ternary lithium batteries or lithium iron phosphate batteries that can only rely on external control systems to ensure safety, lithium titanate batteries are materially safe. When it comes to automobiles, due to the selected spinel lithium titanate structure, the structure of the material has almost no volume change during the process of lithium intercalation, and the lithium intercalation potential is relatively high. Therefore, even if it is used in low temperature and high charges in the later period And other harsh environments, lithium titanate will not touch the potential of metal lithium batteries and reduce the possibility of lithium dendrites short circuit. In addition, even if there is an internal short circuit, the lithium titanate battery can only reach a maximum temperature of 60°C, but cannot reach the temperature at which the battery burns. The main body of lithium titanate is titanium oxide, which does not burn by itself. According to Li Haibo's analysis, the combustion heat of the embedded lithium graphite cathode is about 10 times that of the lithium titanate cathode. Even if the lithium titanate battery burns, it burns slowly and will not explode. His compensation. Li Haibo pointed out that in addition to higher safety, lithium titanate batteries also have three other advantages: top, long service life, high charge and discharge rate, which can reach 10 times or 20 times higher than other types of batteries; second, temperature It has a wide range and can work normally under low or high temperature conditions; thirdly, it can charge and discharge with a high rate. Lithium titanate batteries can be charged in 10 minutes or even 5 minutes, which is much shorter than the 1-hour charging time of ternary lithium batteries. With so many advantages, why don't my country's mainstream automobile products choose lithium titanate batteries? Compared with similar batteries, the energy density of this battery is too low. The energy density of the lithium titanate batteries that can be processed in batches by Guochuang City is 100Wh/kg, which is about 70% to 80% of that of lithium iron phosphate batteries, and only 50% to 60% of ternary lithium batteries. For example, Tesla ModelS has a cruising range of more than 500 kilometers, but if a lithium titanate battery is used, the cruising range may be only 300 kilometers. In addition, the cost of lithium titanate batteries is also higher than that of ternary lithium batteries. Therefore, passenger car manufacturers that put energy density and battery life as their primary considerations have abandoned the battery category. Where is the market for lithium titanate batteries? Although Guochuangcheng was only registered in November 2016 and its batteries were not officially put into production until the end of 2018, Li said that the company’s team members are already engaged in the research and development of lithium titanate batteries. And processing for more than 10 years. They only focus on this battery because they see market opportunities. Customer feedback was very enthusiastic, he said. At present, Guochuang City has reached a large purchase agreement with some rail transit companies, and has obtained some orders in the field of new energy harvesters, and also obtained some orders in customer fields such as logistics. What these customers have in common is that safety is the core attraction and potential threshold, while also weighing economics and battery life. According to Li Haibo's analysis, lithium titanate batteries can reach a high charging rate of 50,000 times, far exceeding the service life of the car. In contrast, lithium iron phosphate batteries and ternary lithium batteries have a high charge and discharge life of only a few hundred times, and even low charge and discharge can only reach thousands of cycles. Due to the large size of vehicles used by Guochuang City customers, a large battery loading space, and relatively low energy density requirements.
