韩国三星电子工业企业成功将锂离子电池的体积比能量提升至700~952瓦时/升,这一数值为现有锂离子电池的1.5~1.8倍,不过据该公司介绍,目前验证的充放电循环寿命仅为200次。新技术的突破关键在于开发出了新型负极材料。新材料的比容量为2500毫安时/立方厘米,而普通的石墨负极材料仅为550毫安时/立方厘米,新材料是其4倍以上,其原理是通过用数层石墨烯对硅微粒子施以涂层处理来实现的。硅的比容量高达约4000毫安时/克,其作为负极材料的巨大潜力早已为
South Korea’s Samsung Electronics Industrial Company succeeded in lithium-ion battery volume ratio of energy to 700 ~ 952 watt hours / liter, the value of 1.5 to 1.8 times the existing lithium-ion battery, but according to the company, the current verification of charge and discharge Cycle life is only 200 times. The breakthrough of new technology lies in the development of a new type of negative electrode material. The new material has a specific capacity of 2500 mAh / cm3 compared to 550 mAh / cm3 for a typical graphite negative electrode material and more than four times as much for a new material. The principle is that by using several layers of graphene, Apply coating treatment to achieve. The specific capacity of silicon is as high as about 4000 mAh / g, and its great potential as a negative electrode material has long been
