After more than 300 years of battery technology, from the initial lead -acid battery to the current lithium ion battery technology, to solid battery technology, nuclear battery technology, colloid battery technology, fuel power battery technology, and so on. However, now relatively speaking, the three battery technology of lithium -ion battery, lead -acid battery, and colloid battery are relatively mature.

　　1. Battery technology: The battery technology is the first to be invented. There are two main types now, one is a lead -acid battery, and the other is a glue battery. These two batteries are large. Most of the electric vehicles on the market are mainly lead -acid batteries.

　　2. Global battery storage technology: It is a kind of non -toxic and pollution -free non -pollution -free inorganic nano powder with halogen silane as raw materials and a high -toxic and pollution -free white non -polluting polymerization reaction in hydroxide flames. Higher surface area, high surface activity, and high purity.

　　3. Fuel-power battery, it is a technology that converts chemical energy in fuel through oxidation-reaction of oxidant and other oxidants and converts into electrical energy. At present, the research on fuel power batteries at home and abroad is mainly concentrated in three parts: anode, electrolyte and cathode.

　　2. Improvement of electrolytes

　　Electrolytic solution is a key factor that determines whether the lithium iron phosphate battery can work normally in low temperature environments. Their performance directly affects the safety and energy density of lithium iron phosphate batteries. At present, the performance of lithium iron phosphate batteries in low temperature environments is mainly based on two aspects of optimizing electrolyte composition and adding active substances. Studies have found that using electrolytic liquid additives such as lithium fluoride, carbonate, and carbonate diacerne can significantly improve the low temperature performance of lithium iron phosphate batteries, and due to the high density of lithium fluoride, it can increase lithium salt and lithium salt and LiOH's quality score, so the additive can make lithium iron phosphate batteries more stable at low temperature; in addition, adding a certain amount of active substances can effectively suppress the side reactions between excessive active substances and electrolytes on the positive pole surface, improve battery electrical performance Essence

　　3. Improvement of production technology

　　Because there are some problems with the production process of lithium iron phosphate batteries, the production process needs to be improved. Taking the high nickel ternary material as an example, the production process is: mixing an appropriate amount of cobalt or nickel in the positive electrode material of lithium ion battery, which can not only improve the cycle performance of lithium iron phosphate batteries, but also reduce battery internal resistance, improve battery battery Compared with energy and reduce the occurrence of side effects. Among them, nickel has a certain protective effect on lithium iron phosphate in low temperature environments. By improving the production process, it can not only improve the performance of lithium iron phosphate batteries, but also reduce the cost of lithium iron phosphate batteries and increase its market competitiveness.
