伴随着经济发展而带来的汽车销量和环境污染问题的双增长是当前汽车行业面临的重要问题。如何摆脱石油依赖,通过汽车动力电动化改善大气污染,以及让国内新能源汽车自主技术实现弯道超车,是国家“十二五”和“十三五”中重点引领方向之一。近几年我国新能源汽车行业发展迅猛,据中国汽车工业协会统计,2014年至2016年我国新能源汽车市场同比增长374%、279%和39%,截止到2016年我国新能源汽车共产销51.7万辆和50.7万辆,是全球新能源汽车的主力市场。作为新能源汽车核心储能元件,动力电池在市场效应和政策利好带动下也
With the economic development brought about by car sales and environmental pollution double growth is the current automotive industry is facing an important issue. How to get rid of the dependence on oil, improve the air pollution through the motorization of electric power, and make the domestic independent innovation of new energy vehicles realize the overtaking of corners are one of the key directions in the national “Twelfth Five-Year Plan” and “13th Five-Year Plan” . In recent years, China’s new energy automotive industry has developed rapidly. According to the statistics of China Association of Automobile Manufacturers, the market for new energy vehicles in China increased 374%, 279% and 39% from 2014 to 2016 respectively. As of 2016, the total sales volume of new energy vehicles in China was 51.7 Million and 507,000, is the main market for new energy vehicles in the world. As the core of new energy vehicles energy storage components, power batteries in the market and policy driven by the favorable
