近几年,全球新能源汽车受到了各国政府的大力扶持与推广,车载动力电池作为新能源汽车的核心部件之一备受关注。对车载动力电池的具体需求、动力电池常见正负极材料技术特征等作了梳理与总结,并提出了未来车载动力电池材料发展趋势。希望能给车载动力电池产业相关企业提供一定的参考。
In recent years,battery which is one of core components of new energy vehicles (EVs) attracted much attention due to the strong supports of governments around the word.The specific requirements of battery and the technical characteristics of common cathode/anode battery materials were summarized.Furthermore,the development trend of EVs battery materials was presented.Hope to give EVs battery related enterprises some references.
