锂离子电池,又称为锂二次电池,是始于20世纪90年代日本索尼推出的采用钴酸锂正极、有机电解液和碳材料负极的可充电化学电源。此后,由于锂离子电池材料与技术的不断发展,它们的各项性能都得到了极大的提升,从而使它们的应用被寄予了更高的期望。锂离子电池作为储能和电动汽车电源方式得到应用和发展相对较晚,但因其比能量/比功率高、循环寿命长等特点被视为最具竞争力的新能源汽车电驱动技术之一,而且其市场规模也越来越大。在强大的社会发展需求和巨大的潜在市场推动下,锂电池新体系不断涌现,动力及储能电池技术正向安全可 Lithium-ion batteries, also known as lithium secondary batteries, are rechargeable chemical power sources that originated in Japan in the 1990s using lithium cobalt oxide positive electrodes, organic electrolytes, and carbon materials. Since then, due to the continuous development of lithium-ion battery materials and technologies, their performance has been greatly improved, so that their applications are placed higher expectations. Lithium-ion battery has been applied and developed relatively lately as an energy storage and electric vehicle power supply, but it is regarded as one of the most competitive electric drive technologies for new energy vehicles because of its high specific energy / specific power and long cycle life , And its market size is also growing. Under the impetus of strong social development and huge potential market, the new lithium battery system is constantly emerging, and the power and battery technology are positively safe
