能源危机和日益严重的环境污染使汽车技术经历着燃料多元化、动力电气化等重大技术变革.发展高效节能、低排放或零排放的电动汽车已成为全世界的共识和共同努力的目标.然而,电动汽车用关键核心部件——动力电池,目前存在能量密度低、一次充放电运行距离短等缺点,严重制约了电动汽车的普及应用.世界各国政府、各大公司和各种组织机构,在规划、资金、技术等方面相互联合,加快动力电源的发展,以实现从燃油汽车向电动汽车的转变.为了加速发展“更加不依赖资源,更加环保,更加可持续”的新能源汽车技术,我国已公布了《节能与新能
The energy crisis and the increasingly serious environmental pollution have caused the automotive technology to undergo major technological changes such as fuel diversification and power electrification and the development of energy-efficient, low-emission or zero-emission electric vehicles has become the consensus of the world and the goal of joint efforts.However, Power battery, the key core component of electric vehicle, has the shortcomings of low energy density and short running distance of one charge and discharge, which seriously hampered the popularization and application of electric vehicles.Government, major corporations and various organizations all over the world, , Capital and technology to speed up the development of power supply in order to realize the transformation from fuel-powered vehicles to electric vehicles.In order to accelerate the development of new-energy vehicle technologies that are “less resource-dependent, more environmentally-friendly and more sustainable” China has announced "energy saving and new energy
