Description

一种可充电锂离子电池
技术领域
本发明属于充电电池技术领域，尤其涉及一种可充电锂离子电池。
背景技术
锂离子电池是一种二次电池（充电电池），它主要依靠锂离子在正极和负极之间移动来工作。在充放电过程中，Li+ 在两个电极之间往返嵌入和脱嵌：充电时，Li+从正极脱嵌，经过电解质嵌入负极，负极处于富锂状态；放电时则相反。
由于便携式电子产品的发展，充电锂离子电池以其具备高电压、高容量、可重复充放电使用、安全性好、自放电小、无记忆效应、可快速充电等特性，得到了广泛的应用。然而，由于锂离子电池能量密度高，在过充、过放、过流、短路及超高温充放电、过低温使用时，容易损坏。为此，现有的锂离子电池都加装电池保护板，以保护锂离子电池的电芯保护界面。常用的锂离子电池加装保护板的设计方式，是在电芯的头尾或侧面加装保护板，且电池本身不带充电状态指示功能。
目前的圆柱电池，需要外加保护板进行充放电的保护，需要将正极通过镍带跨过电芯侧边连接负极端的保护板，或者需要将保护板放在正极，从电芯底部点焊引出镍片，连接到正极端的保护板，并将保护板的另一端引出镍片，连接到电芯底部负极端并做一个五金触片输出，这种结构需要正极镍带跨过电芯表面，存在镍带毛刺刺破电芯外部绝缘套管导致短路的隐患，且不能直接用充电线对电池进行充电，需要配备专用的充电器才能进行充电，电池本身也不带充电状态指示功能。因此有必要进行改进。
发明内容
本发明的目的在于提供一种可充电锂离子电池，用于提供一种充电线直接充电、充电状态进行指示的可充电电池。
为实现上述目的，本发明提供如下技术方案：
一种可充电锂离子电池，该可充电锂离子电池包括PET套管、PET垫片、电芯、钢套、保护板、上支架、下支架和底片；所述下支架和底片分别固定在电芯的两端，所述下支架的上端固定安装有保护板，所述保护板包括表面中部固定安装有的正极接触片，靠近正极接触片固定安装有的LED指示灯以及保护板槽口处固定安装有的Micro USB母座，所述保护板的上端固定安装有上支架，所述下支架与上支架卡合连接，所述上支架和下支架外部设置钢套，所述钢套的下端与电芯头部一端的负极外壳紧密铆接固定，所述钢套的上端固定设置有PET垫片，所述PET垫片为半透明材质，LED指示灯的灯光可透过PET垫片，对充电状态进行指示，所述正极接触片从钢套中部和PET垫片中部穿出，所述钢套的侧边开有一通孔缺口，通孔缺口与所述Micro USB母座接口对应连接，所述PET套管套设在整个电池外部。
本发明的有益效果是：本发明提供的可充电锂离子电池，通过采用Micro USB母座接口作为通用型的接口，使用充电线通过Micro USB母座接口就可直接对电池进行充电，充电简单方便，具有良好快速的电力传输能力，充电时间短，且通过设有的LED指示灯对充电状态进行指示，提高了可充电电池的便利性，实用性强。通过设有的上支架、下支架和钢套，钢套使电池各部件成一整体及负极导电，上支架和下支架起到良好的支撑定位保护板的作用，同时也起到了绝缘效果。电芯下端设置有底片，有效保护电池底部磨损变形，钢套的顶端固定设有PET垫片，起到绝缘作用，PET垫片为半透明材质，LED指示灯的灯光可透过PET垫片，对充电状态进行指示。
