Shallow of ternary lithium battery and lithium iron phosphate battery usage and performance characteristics

Source: 2020 - 04 - 20 so he hits: manganese acid lithium battery can reduce cobalt and rare element, and cobalt element must be used in the ternary lithium batteries. At the same time, along with the lithium battery system in less attention on the market, manganese acid lithium battery system began eating into the market. With the cost advantage and performance improvement, to give priority to with lithium iron, new energy bus market impact. 1. The first three batch of power battery directory support amount of manganese acid lithium is the third big battery system of the first three batch of new energy vehicles catalogue published 1328 product. In auxiliary power battery, lithium iron phosphate is still the mainstream of form a complete set of battery system, application model reached 55%. Ternary lithium battery application model accounted for 25%, because of its high energy density, in line with the policy planning, cost control is considered a mainstream power battery application system in the future. After market for manganese acid lithium battery system less attention, in the first three batch of form a complete set of model accounted for 16%, has become a force to be reckoned with. The ternary lithium battery and lithium iron phosphate 2. Manganese acid lithium has become another major application of mainstream electric model system in the first three batch of new energy promotion model directory, the application of lithium manganate system is still a plug-in hybrid vehicles as the main application field, can't ignore the lithium manganese acid salt as the main application of pure electric vehicle model has 36, accounting for 17% of lithium manganate support model. Lithium manganese acid in the application of pure electric bus model is one of the most baic new energy, followed by xiamen jinlong and CSR. In addition, zhongtong, yutong, the Yangtze river, nk, dragon, and xing are already used in pure electric bus model lithium manganese acid. Lithium manganese acid has become the mainstream of pure electric vehicles and the application system 3. Lithium manganese acid has a strong price advantage in the new energy automobile lower subsidies and market promotion, under the dual role of the three power lithium battery in the system, the price advantage of manganese acid lithium will particularly. After the price surge, the ternary material price remains at 180 - A high of 190000 yuan/ton. Due to the high expectations and ternary material limited release of production capacity, the price will be adjusted, but will remain high. Mainstream lithium iron phosphate market prices remain at 8. About 50000 yuan/ton, fell 20000 yuan/ton, 20% decline. Lithium manganese acid, as a result of the front-end enough supply of materials, the material price is only 50000 yuan/ton, the biggest impact on its lithium carbonate, lithium mineral energy release in qinghai province, and can be expected future price fluctuation in the lithium manganese acid salt. 4. Manganese acid lithium performance is excellent, with a high degree of policy combining released the first three batch of new energy promotion model directory, pure electric vehicles of manganese acid lithium battery energy density is to support more than 115 wh/kg, change the previous market manganese acid lithium energy density is low, the starting point of research, SPIR) Constant peng clark, star, a few manganese acid lithium battery, such as enterprise research, found that manganese acid lithium battery SOC cycle can reach 2000 degrees Celsius, and the ternary. In the double requirements of energy density and fast charging performance, the power performance of manganese acid lithium battery, can discharge permeance, low temperature performance and high voltage frequency characteristic can meet the demand of the market. In the early days, the battery pack is mainly refers to the processing, assembly and packing lithium-ion battery pack. Lithium batteries battery assembly into a set of process known as battery, the battery pack can be a single cell, can also be a series-parallel lithium-ion battery pack. Package including battery, bus bar, soft connection, protection board, the outer packing, the output ( Including the connector) , highland barley, auxiliary materials such as paper, plastic stents. Lithium battery system adopts the mechanical structure of the series and parallel multiple single cells, and considering the mechanical strength, thermal management and system matching BMS. Its main technology embodies in the whole structure design, welding and machining process control, protection grade, active thermal management system, etc.
