技术领域technical field
本发明涉及锂电池技术领域，具体为一种带支架电动自行车用锂电池。The invention relates to the technical field of lithium batteries, in particular to a lithium battery for an electric bicycle with a bracket.
背景技术Background technique
“锂电池”，是一类由锂金属或锂合金为负极材料、使用非水电解质溶液的电池。1912年锂金属电池最早由Gilbert N.Lewis提出并研究。20世纪70年代时，M.S.Whittingham提出并开始研究锂离子电池。由于锂金属的化学特性非常活泼，使得锂金属的加工、保存、使用，对环境要求非常高。所以，锂电池长期没有得到应用。随着科学技术的发展，现在锂电池已经成为了主流。"Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M.S.Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream now.
锂电池大致可分为两类：锂金属电池和锂离子电池。锂离子电池不含有金属态的锂，并且是可以充电的。可充电电池的第五代产品锂金属电池在1996年诞生，其安全性、比容量、自放电率和性能价格比均优于锂离子电池。由于其自身的高技术要求限制，现在只有少数几个国家的公司在生产这种锂金属电池。Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batteries, the fifth generation of rechargeable batteries, were born in 1996, and their safety, specific capacity, self-discharge rate and performance-price ratio are superior to lithium-ion batteries. Due to its own high technical requirements, only companies in a few countries are currently producing such lithium metal batteries.
