Lithium button battery is small in size,large in capacity and stable in performance,it is often used in our daily life,various remote controls,remote keys,watches and other devices can not do without it.
What are the important components in lithium button battery?
What is the use value of lithium button battery?
What is the internal structure of the lithium button battery?
1.Spacer
The spacer is a round aluminum piece with the same diameter as the size of the lithium piece. In the experiment, different sizes and thicknesses can be purchased as needed.
Note: Spacers, positive and negative shells and other components should be cleaned with alcohol repeatedly by ultrasonic before use, and then dried with a blast dryer.
2.Shrapnel (support piece)
Shrapnel is mainly used to support the battery. Without the shrapnel, the battery will be very flat in the pressure cell step and the internal components may be crushed. The shrapnel is added to the negative side only, but if the shrapnel is added to both the positive and negative side, the buckling cannot be closed in the pressure cell step, resulting in the electrolyte coming in contact with air and the experiment failing.
3.Electrolyte.
Different materials generally correspond to different electrolytes, do not try to save trouble in the experiment, small quantities of electrolytes can be requested from the company, and will generally be given. Individual special electrolytes, such as low-temperature electrolytes, may need to be purchased at a good price.
Lithium button batteries are used to power small portable electronic devices such as watches and pocket calculators. The more widespread variant is often called a button battery. Devices that use lithium button battery are typically designed around batteries with a long life, typically over a year of continuous use in a watch. Most coin cell batteries have a low self-discharge rate and will hold their charge for a long time if they are not used. Relatively high-powered devices such as hearing aids may use zinc-air batteries, which have a much higher capacity for a given size, but will dry out after even a few weeks of non-use.
We first need to understand the components inside the lithium button battery. Every lithium-ion battery has an anode, a cathode, an electrolyte, and a spacer. In most lithium-ion batteries, manufacturers use graphite for the anode. Commonly used anode materials include lithium iron phosphate, lithium cobaltate, and lithium manganate.
Between the anode and cathode is a liquid electrolyte, usually made from lithium salts. As the battery discharges (powers your devices), lithium ions flow from the anode to the cathode and through the separator, forcing electrons to power your electronic devices.
Guangzhou Dolphin Information Technology Co., Ltd. has been concentrating on lithium button batterys for several years.They will make every effort to meet the needs of users.
