Lithium iron phosphate battery is analysed and the difference between the ternary lithium batteries

Takeaway: lithium-ion battery is one of the most commonly used type of battery electric vehicle, although the time is not long since 1970, with the characteristics of high energy density, long service life of cycle quickly occupied the most part of the electric car battery market. Now, in the sale of electric vehicles equipped with lithium batteries are mainly the lithium iron phosphate batteries and two kinds of ternary lithium batteries. So the lithium iron phosphate batteries and ternary battery and what the difference? Power battery is the core of the electric car, it is the only source of pure electric vehicle drive energy, is directly related to the dynamic properties of electric vehicles, battery life, and is directly related to the safety of the electric car. Cost of new energy vehicles, battery power system takes up a 30 - cost of new energy vehicles 50%. And since the electric car was born, power battery technology has the practical process of electric vehicles. Improve the power density, energy density, service life and reduce the cost has been the core of electric vehicle power battery technology research and development. Lithium battery is one of the most commonly used type of battery electric vehicle, although the time is not long since was born in 1970, but with high energy density, long service life of cycle quickly occupied the most part of the electric car battery market. Now, in the sale of electric vehicles equipped with lithium batteries are mainly the lithium iron phosphate batteries and two kinds of ternary lithium batteries. So the lithium iron phosphate batteries and ternary battery and what the difference? 【 Shape packing 】 Square batteries, lithium-ion batteries can be divided into soft package and cylindrical cell battery. 【 Material system. The current mainstream with lithium iron phosphate batteries, batteries ternary material respectively is refers to the lithium iron phosphate and ternary material as the anode material of lithium ion batteries. Ternary material refers to the Ni, Co, Mn, Ni, Co or Al three kinds of metal elements as the core element of the anode materials. 【 Comprehensive evaluation of 】 Lithium iron phosphate battery monomer, the energy density of 120 wh/kg, after the group of 80 wh/kg; The ternary lithium battery monomer, the energy density of 180 wh/kg, after the group energy density of 110 wh/kg. From the point of view, in terms of energy density, the ternary lithium battery is better than that of lithium iron phosphate batteries; In terms of cycle life, quite, both single cell cycle life are more than 3000 times, after the battery group, and because of the bad working condition becomes complicated, life will reduce to a certain extent, the battery (6 150000 kilometers. EV200 use batteries for ternary lithium battery. The current lithium iron phosphate battery energy density has been basically achieved the perfection of theory, and three yuan energy density of battery has much room to improve. Comprehensive ability density, power density, cycle life, low temperature performance, etc. , three yuan comprehensive performance is better than that of lithium iron phosphate batteries of the battery. Concentrate on electric lithium battery and lithium battery, using the international most advanced ternary lithium battery, let your electric cars use time longer, more powerful.
