Those who are interested can take a look at my other papers at http://www.haolin.biz/UserForum/blog/bloghome.html. Lithium hexafluorophosphate is widely used as an electrolyte in lithium-ion batteries due to its good electrical conductivity and electrochemical stability. It is primarily used in lithium-ion power batteries, lithium-ion energy storage batteries, and other consumer batteries, and it remains an irreplaceable electrolyte for lithium-ion batteries in the near to medium term. The surge in demand from the new energy electric vehicle industry has created a supply-demand gap for lithium hexafluorophosphate at the upstream level. Due to a demand that exceeds supply, the price of lithium hexafluorophosphate has been rising steadily since the second half of last year, increasing from 90,000 yuan per ton in mid-2015 to around 400,000 yuan per ton at present. Lithium hexafluorophosphate presents high technical barriers and a long expansion cycle, making it difficult for new manufacturers to enter the market; most of the additional production capacity comes from existing manufacturers, with only a few companies in China capable of producing it on a large scale. Currently, domestic companies with the capacity to produce lithium hexafluorophosphate have begun expanding their production capacities. However, due to the complexity and time-intensive nature of setting up such production facilities, it takes at least a year to complete these expansions, which means that the market supply situation will remain tight. As countries around the world make further progress in energy conservation, emission reduction, and environmental protection, this will surely drive rapid growth in the lithium-ion battery industry, leading to an even greater demand for lithium-ion battery electrolytes. Next, let’s talk about six types of lithium-ion batteries. Lithium iron phosphate (LFP): Also known as lithium phosphate batteries, these batteries use phosphates as their cathode. They possess the ability to reversibly insert and remove lithium ions. This is because, in the LiFePO4 structure with a complex anion (PO4)3-, the replacement of oxygen ions with phosphate ions alters the material’s three-dimensional structure. This not only creates more space for the movement of lithium ions but also helps to maintain stable potentials for their insertion and removal, resulting in excellent electrochemical properties. Lithium phosphate batteries feature low electrical resistance, and the P-O bonds in lithium iron phosphate crystals are stable and difficult to break down. Even under high temperatures or overcharging, they do not suffer structural collapse, generate heat, or produce highly oxidizing substances like lithium cobalt oxide; as a result, they possess excellent safety and thermal stability. Due to its stable structure, long cycle life, and good compatibility with most electrolyte systems, the lithium iron phosphate cathode material exhibits favorable volume effects when used in combination with carbon anode materials, as well as good storage performance ; Moreover, it is rich in resources, has low costs, low toxicity, and causes no pollution; it is one of the materials that are currently the focus of intense research and development in the battery industry. Therefore, such batteries are often used in electric motorcycles and other applications that require a long service life and high safety standards. Electric vehicles can also use this type of battery depending on the space available for the batteries. BYD, a vertically integrated company from China, prefers lithium iron phosphate batteries, claiming that they are a safer and cheaper option; although their energy density is slightly lower, it can be improved by raising the voltage. Lithium cobalt oxide (LCO): The lithium cobalt oxide batteries mentioned in lithium phosphate batteries are also known as lithium-ion cobalt batteries; such batteries are made from lithium carbonate and cobalt. Due to their high capacity, these batteries are used in mobile phones, laptops, and digital cameras. In addition to the disadvantages of this type of battery mentioned above, it also has issues such as a short lifespan and limited electrical conductivity. This means that devices using these batteries need to be charged relatively frequently, which has always been a problem for smartphone users. Furthermore, the safety of this battery is not as good as that of other types. What can be soft isn’t just girls; batteries can be too. Previous reports have indicated that this type of battery can change its traditional shape, being bendable and knottable, which will bring about new changes in electronic products. Lithium manganese oxide (LMO) Lithium manganese oxide batteries are commonly referred to as lithium manganate or lithium-ion manganese batteries; they also have a beautiful name – spinel. This type of battery technology was first discovered in the 1980s, with the first publication on the subject appearing in 1983 in the ‘Materials Research Bulletin’. In 1996, Moli Energy produced the first commercial lithium-ion battery that used lithium manganese oxide as the cathode material. Lithium manganese oxide batteries are renowned for their high thermal stability and safety compared to other types of lithium-ion batteries. Therefore, such batteries are commonly used in medical devices and electronic appliances, as well as in power tools, electric bicycles, and applications for electronic hobbies. Lithium manganese oxide batteries can also be used to power laptops and electric vehicles. Representative models in the commercial market for such batteries are the Nissan Leaf and the General Motors Volt. However, the problems of poor high-temperature cycling and storage performance have always been the key factors limiting its use in power lithium-ion batteries. Lithium nickel cobalt manganese oxide (NMC) is an upgraded version of lithium iron phosphate; lithium nickel cobalt manganese oxide batteries are also known as nickel cobalt manganese ternary materials (NMC). Lithium nickel cobalt manganese oxide batteries are made from several other common materials used in lithium-iron batteries. These include nickel, manganese, and cobalt cathode composite materials. NMC batteries can have high specific energy or high specific power, but they cannot possess both of these properties at the same time. This type of battery is most common in power tools and vehicle power systems. The typical cathode composition is one-third nickel, one-third manganese, and one-third cobalt, which means that the cost of raw materials is lower compared to other options, as cobalt is quite expensive. According to Battery University, such batteries are also usually the preferred choice for electric vehicles due to their low self-heating rate. However, since cobalt is a rare metal and the majority of its reserves are located in the politically unstable **Congo, cobalt prices may rise in the future. In the future, there may be a situation where even the most skilled cook cannot prepare meals without ingredients, which shows that lithium iron phosphate batteries still have the advantage of using inexpensive and readily available materials. Lithium nickel cobalt aluminum oxide (NCA) batteries, also known as NCA cells, are becoming increasingly important in electrical power systems and grid storage. NCA batteries are not common in the consumer industry, but they hold promise in the automotive sector. NCA batteries offer an option for high-energy, long-lasting batteries, even though they are not safe and can be very expensive. Boston Consulting Group states that safety measures must accompany the installation of NCA batteries in vehicles, with monitoring of these batteries’ performance and behavior to ensure driver safety. The Argonne **Laboratory has studied the potential of NCA batteries as well as any material-related issues that may be associated with them. Given the increase in the market share of electric vehicles, and since these vehicles typically use NCA batteries, demand for lithium in the United States is set to rise sharply. Of course, such batteries also face the issue of rare transition metals. Lithium titanate (LTO), also known as lithio-titanate, is a battery with a wider range of applications. Since lithium-titanate batteries utilize advanced nanotechnology to create the battery structure, their main advantage is the ability to charge quickly. However, the density of lithium titanate batteries remains higher than that of other non-lithium-ion batteries, which is an advantage. These batteries can be used in fields including ** and aerospace, as well as for storing wind and solar energy to create smart grids. Furthermore, the battery capacity indicates that these batteries can also be used as a critical backup for power systems. Currently, manufacturers use lithium titanate in battery electric vehicles and bicycles, and this type of battery may also be used in electric buses for public transportation. However, these batteries have a lower inherent voltage or a lower energy density compared to other lithium batteries, and the issue now is how to drive vehicles effectively.
