技术领域technical field
本实用新型涉及磷酸铁锂锂电池技术领域，具体为一种用于无线手持式吸尘器的锂电池组。The utility model relates to the technical field of lithium iron phosphate lithium battery, in particular to a lithium battery pack used for a wireless hand-held vacuum cleaner.
背景技术Background technique
锂电池是由爱迪生发明的一类由锂金属或锂合金为磷酸铁锂锂电池负极材料、使用非水电解质溶液的电池。在以前，因为锂金属的化学性质非常活泼，对加工、保存、使用，对环境要求非常高，所以磷酸铁锂锂电池长期没有得到应用。随着现代科学的发展磷酸铁锂锂电池现在已经成为了主流。旅客乘飞机托运禁止携带磷酸铁锂锂电池。磷酸铁锂锂电池(Lithium battery)是指电化学体系中含有锂(包括金属锂、锂合金和锂离子、锂聚合物)的电池。磷酸铁锂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，现在只有少数的几个国家的公司在生产这种锂金属电池。磷酸铁锂锂电池通常有两种外型：圆柱型和方型。电池内部采用螺旋绕制结构，用一种非常精细而渗透性很强的聚乙烯薄膜隔离材料在正、磷酸铁锂锂电池负极间间隔而成。磷酸铁锂锂电池正极包括由钴酸锂(或镍钴锰酸锂、锰酸锂、磷酸亚铁锂等)及铝箔组成的电流收集极。磷酸铁锂锂电池负极由石墨化碳材料和铜箔组成的电流收集极组成。电池内充有有机电解质溶液。另外还装有安全阀和PTC元件(部分圆柱式使用)，以便电池在不正常状态及输出短路时保护电池不受损坏。单节磷酸铁锂锂电池的电压为3.7V(磷酸亚铁锂磷酸铁锂锂电池正极的为3.2V)，电池容量也不可能无限大，因此，常常将单节磷酸铁锂锂电池进行串、并联处理，以满足不同场合的要求。Lithium battery is a kind of battery invented by Edison, which uses lithium metal or lithium alloy as the negative electrode material of lithium iron phosphate lithium battery and uses non-aqueous electrolyte solution. In the past, lithium iron phosphate batteries have not been used for a long time because the chemical properties of lithium metal are very active, and the requirements for processing, storage, and use are very high for the environment. With the development of modern science, lithium iron phosphate lithium battery has now become the mainstream. Passengers are prohibited from carrying lithium iron phosphate lithium batteries as checked baggage. Lithium iron phosphate battery (Lithium battery) refers to a battery containing lithium (including metal lithium, lithium alloy, lithium ion, lithium polymer) in the electrochemical system. Lithium iron phosphate 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 a few companies in a few countries are producing such lithium metal batteries. Lithium iron phosphate batteries usually have two shapes: cylindrical and square. The inside of the battery adopts a spiral wound structure, and a very fine and highly permeable polyethylene film separator material is used to space the positive and negative electrodes of the lithium iron phosphate battery. The positive electrode of lithium iron phosphate lithium battery includes a current collector composed of lithium cobalt oxide (or lithium nickel cobalt manganate, lithium manganate, lithium iron phosphate, etc.) and aluminum foil. The negative electrode of lithium iron phosphate lithium battery is composed of graphitized carbon material and current collector composed of copper foil. The battery is filled with an organic electrolyte solution. In addition, a safety valve and a PTC element (partial cylindrical use) are installed to protect the battery from damage when the battery is in an abnormal state and the output is short-circuited. The voltage of a single-cell lithium iron phosphate battery is 3.7V (the positive electrode of a lithium iron phosphate lithium battery is 3.2V), and the battery capacity cannot be infinite. Therefore, a single-cell lithium iron phosphate battery is often connected in series. , Parallel processing to meet the requirements of different occasions.
然而传统的锂电池组耐高温性差，长时间使用后温度急剧升高，电池寿命衰减严重。However, the traditional lithium battery pack has poor high temperature resistance, the temperature rises sharply after long-term use, and the battery life is seriously attenuated.
因此需要一种新型高效的锂电池组其特点是寿命长、充放电倍率大、安全性好、高温性好、元素无害、成本低。Therefore, there is a need for a new type of high-efficiency lithium battery pack, which is characterized by long life, high charge and discharge rate, good safety, good high temperature resistance, harmless elements, and low cost.
