The "New Energy Vehicle Power Battery Materials and Industrial Chain Report 2020" is Officially Released
汽车工业正在发生变革，未来汽车工业朝着电动化、智能化、互联化方向发展。新能源汽车具有环保、节能的独特优势。为适应国际能源供应紧缺以及日益高涨的环境保护呼声，发展新能源汽车已经成为世界各国的共识，中国政府也把发展新能源汽车写进《中国制造2025》。
The automobile industry is undergoing transformation, and the future automobile industry will develop towards electrification, intelligentization and interconnection. The new energy automobile has the unique advantage of environmental protection and energy saving. To adapt to the international energy supply shortage and the rising environmental protection, developing new energy vehicles has become the world's consensus, and the Chinese government has also put the development of new energy vehicles in the "Made in China 2025" plan.
2019年国五国六换挡，双积分制落实，在整个车市消费环境呈现不景气的大背景下，上半年中国新能源汽车产销继续保持稳步增长态势，但受补贴退坡的直接影响，下半年新能源汽车销量呈现断崖式下跌。在2019年，电池能量密度、续航里程、单位能耗三方面依然是衡量企业能否获取到足额补贴的核心技术指标。
China's 2019 vehicle emission standards -"light vehicle pollutants and measurement methods" - Phase 5 standards and phase 6 standards shift gears, and the double-integral policy is implemented. In the overall car market consumption environment presents the big background, the first half of China's new energy vehicle production and sales continue to maintain a steady growth trend. However, the subsidies by the direct impact of the second half of the new energy vehicle sales cliff-like decline. In 2019, battery energy density, battery range, and unit energy consumption are still the core technical indicators to measure whether enterprises can obtain full subsidies.
2020年受新型冠状病毒肺炎疫情的影响，3月为有效防控疫情同时有力推动复工复产，中国新能源汽车购置补贴和免征购置税政策延长2年。那么在2年后完全断补意味着迎合补贴政策展开的造车理念亦或是电池设计理念都将结束。车企们设计一辆新能源汽车的思路将围绕安全、成本、消费者体验来展开。
Affected by the 2019-ncov epidemic in 2020, China's subsidies and tax exemptions for new energy vehicle purchases were extended for two years in March to effectively control the epidemic and promote the resumption of production. A full stop after two years would mean the end of either the car idea or the battery design idea, which was developed to cater to the subsidy policy. Car companies will design a new energy vehicle around safety, cost, consumer experience to launch.
电池技术是新能源汽车发展的核心技术之一，是新能源汽车技术的重中之重，制约新能源汽车的续航里程、行驶安全以及成本。断补后企业需要承担大幅度补贴退坡所带来的成本的上涨，加上多次新能源汽车自燃事故之后，"热失控"对新能源汽车产业的负面影响，未来动力电池材料技术将如何发展？目前，在乘用车领域，三元锂电池由于能量密度高、续航能力强仍是主流的发展方向。比亚迪在2020年3月发布了新一代磷酸铁锂电池"刀片电池"动力电池，预计市场将再掀起磷酸铁锂热潮。安全性和循环寿命更好、价格上更实惠的磷酸铁锂电池能否在断补后逆袭？
Battery Technology is one of the core technologies in the development of new energy vehicle, and it is the most important technology of new energy vehicle. After the break-up, the enterprises need to bear the rising costs brought about by the large-scale subsidy, plus the negative impact of the "heat out of control" on the new energy automobile industry after the multiple spontaneous combustion accidents of new energy vehicles, how will power cell material technology develop in the future? At present, in the field of passenger cars, ternary lithium batteries because of high energy density, endurance capacity is still the mainstream direction of development. Jády in March 2020 released a new generation of lithium iron phosphate battery "blade battery" power battery, the market is expected to set off a lithium iron phosphate battery craze. Can the lithium iron phosphate battery with better safety, cycle life and more affordable price recover after broken ？
基于此，中国汽车材料网对新能源汽车的核心技术动力电池及其产业链进行梳理，重磅发布2020版《新能源汽车动力电池材料及产业链》报告。报告主要内容涵盖新能源汽车及动力电池产业发展、新能源汽车动力电池技术发展、汽车动力电池产品供应链及汽车动力电池年度发展情况等四个方面（见下图目录），精彩内容抢先看！
based on this, China Automotive Materials Network collated the core technology of new energy vehicle power battery and its industrial chain, and released the"New Energy Vehicle Power Battery Materials and Industrial Chain Report 2020". The report covers the development of new energy vehicle and power battery industry, the development of new energy vehicle power battery technology, the supply chain of vehicle power battery products and the annual development of vehicle power battery (see the table of contents below) , let's see what happens first!
