Will the processing cost of lithium batteries fall in the future?

The processing of lithium battery packaging materials is divided into five parts: positive electrode material, positive electrode material, copper foil and aluminum foil, gap, electrolyte and so on. At present, the four parts of materials, gap, electrolyte, anode material, and anode material, account for 85% of the cost of battery power. The performance of the negative electrode material directly affects the performance of the lithium battery, and its cost directly determines the cost of the battery. Lithium battery pack is a new generation of excellent green energy storage battery, which has become one of the key points of high-tech opening. Lithium batteries have the advantages of large capacity, no recall effect, small size, wide temperature planning, many cycles, and long service life. Will the decline in the cost of lithium battery packs end? With the decline in state subsidies for electric vehicles, the decline in lithium battery capital has gradually become more important to new energy operations. Lithium battery packaging manufacturers strive to reduce costs and actively respond to market competition without subsidies. In the past few years, the cost of lithium batteries has almost fallen by half. As long as the cost of the battery drops to US$100/kWh, the cost of electric vehicles will be close to the cost basis of fuel vehicles; the cost of the battery has been reduced to US$150/kWh, and electric vehicles are more competitive than environmentally friendly concepts. In terms of energy storage, the cost of lithium iron phosphate batteries has dropped from the current US$470 per kilowatt-hour to US$230, even without subsidies. Several methods to reduce the cost of lithium battery packs: 1. Improve the standard lithium battery pack of lithium batteries by hundreds of single cells in series and parallel. At that time, it was important for battery companies to reduce battery manufacturing costs to improve the material system, formulate battery standards and Trek battery yield method. To make the standard for larger batteries, then, whether square, cylindrical or soft-pack batteries show the trend of opening and expansion of single-cell standards, its advantage is that it is conducive to the energy density trek of the lithium battery system and reduces the number of cells, and then reduces cost. 2. The lightweight structural part is an important part of the lithium battery pack and the battery module, battery case, top cover, steel/aluminum case, positive and negative electrode soft connection, battery soft connection row and other lithium battery precision structure parts, Although the cost of power lithium-ion batteries does not account for a large proportion, it has also become a price point for battery companies. In 2018, many lithium battery pack manufacturers reduced the weight of new products by more than 20% compared to old products by introducing new materials and optimizing structural design, thereby further reducing manufacturing costs and thereby reducing the overall cost of battery packs. In addition to the above structural parts, accessories such as boxes and wiring harnesses are also an important part of the direct cost of the battery company. 3. Compared with other materials, BMS battery treatment system has a greater price reduction. Many BMS companies stated that BMS capital only accounts for 5%-10% of the price of lithium battery packs, but under the pressure of subsidy withdrawal, BMS companies will also be under pressure to reduce prices. It is expected that prices will drop by more than 20% in 2018. 4. Trek automation ability to reduce unit processing costs through processing line automation and processing plans is also an effective way for power lithium-ion battery companies to reduce unit processing costs. By improving the process and processing technology, ending the intelligent and planned processing, the irregular material utilization rate and product qualification rate have significantly reduced the processing cost of battery materials and battery packs. 5. The cost of purchasing the entire line of downstream lithium battery packs. In recent years, with the rapid expansion of power lithium-ion battery processing capacity, lithium battery manufacturers have gradually tended to package various equipment for bidding in order to reduce costs. Orders and market share are gradually converging, and large lithium battery equipment companies have mastered the entire line of central equipment. Abstract: The continuous decline of lithium battery packaging and processing costs is the result of a series of factors that are used together, including policy guidance, technology, processing plans, equipment procurement costs, and the one-sided perseverance of operators. However, in the face of the general trend of collaboration and opening up, it is necessary for upstream and downstream companies in the industrial chain to jointly assume this responsibility and establish a complete industrial value in order to achieve the goal of cost redistribution.
