[0002] Lithium battery (Lithium Cell) refers to the most basic electrochemical unit containing lithium (including metallic lithium, lithium alloys, lithium ions, and lithium polymers) in the electrochemical system. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. Lithium ion batteries generally use lithium alloy metal oxides as positive electrode materials, graphite as negative electrode materials, and use non-aqueous electrolytes.

[0003] However, lithium batteries are currently installed inside devices and are often replaced and disassembled, or are used improperly, or deformed due to long-term use. This makes them very inconvenient to remove and has high maintenance costs. In addition, most lithium batteries on the market do not have handles or use stickers as handles. However, stickers used as handles do not adhere properly and are easily broken. In addition, stickers are easily weathered when stored for too long, making them inconvenient to disassemble.
