3.6V Micro Lithium-ion Batteries

LiPol Battery Co., Ltd supplies rechargeable micro lithium-ion battery for worldwide companies, these micro lithium-ion batteries can be used for high-tech products, such as medical equipment, Bluetooth headsets, wireless earphones, fitness trackers, e-cigarette, baby monitoring, hearing aid, pet wearables, smart toys, watches. We have been working on researching more shapes and capacities of batteries. LPM series 3.6v micro lithium-ion batteries are specially designed for wearable devices. It can meet the capacity of 18mAh to 120mAh in a limited space, and the voltage of 3.6v can meet different needs.

Micro lithium-ion batteries are a specific type of lithium-ion battery that comes with a sturdy outer casing to safeguard the battery cells within. The hard case of a lithium-ion battery is typically made of materials such as plastic, metal, or composite materials that are designed to withstand impacts and protect the battery cells from damage. The internal cells of a hard case lithium-ion battery are the same as those used in other lithium-ion batteries, consisting of a positive electrode made of lithium cobalt oxide, a negative electrode made of graphite, and a lithium-ion electrolyte.

Rechargeable micro lithium-ion (Li-ion) batteries are widely used in electronic devices like smartphones, laptops, and electric vehicles due to their high energy density, long cycle life, and low self-discharge rates. These batteries work by storing and releasing energy through the movement of lithium ions between two electrodes, typically made of lithium cobalt oxide (positive electrode) and graphite (negative electrode). As the battery charges, lithium ions move from the positive electrode to the negative electrode for storage, and during discharge, they move back to the positive electrode, releasing energy in the process.

We focus on the market requirements of modern high-tech electronic devices, and provide rechargeable high-capacity Lithium-ion batteries, which have a round button shape.
