18650 Lithium-ion Battery Supply at Sunpower New Energy

Our 18650 lithium-ion battery cells deliver safe, stable, and reliable performance to you, boasting a discharge rate that is 3-10 times higher than standard batteries. It’s designed to meet various applications, like home electronics, electric bicycles, power tools, gardening equipment, vacuum cleaners, snow scooters, drones, military and other fields.

What’s the feature of the 18650 Li-ion battery?

The 18650 battery is a type of rechargeable lithium-ion battery featuring high energy density, long cycle life, and reliability. The name “18650” comes from its dimensions: 18 mm in diameter and 65 mm in length.

1 Longer Cycle Life

The 18650 lithium-ion rechargeable battery can endure a large number of charge-discharge cycles (>600 cycles). With better battery design and electrode materials, the 18650 batteries can minimize electrolyte decomposition and electrode wear, thereby extending the battery lifespan. With a longer cycle life, our 18650 lithium-ion battery cells can exceed 3000 charge/discharge cycles at 0.3C. Even under high discharge rates of 5-10C, they maintain a robust cycle life of 500-1200 cycles, ideal for applications requiring frequent and rapid energy replenishment.

2 Safe & High Quality

Sunpower 18650 li-ion batteries are awarded UL/CB/SGS/BIS/PSE/KC/MSDS/UN38.3 certification to ensure high quality. In the calcination process, we add metal into node material, which can promote the crystal structure stability of lithium cobalt oxide at high temperatures, reduce the oxidation capacity of the material, and inhibit the reaction between the electrode material and the electrolyte

3 Adapt for More Application

Our 18650 li-ion battery can be used in a high-temperature environment, with a maximum operating temperature of 85℃. It not only adapts to more environments but is fit for various applications, including electric propelling applications, energy storage systems, light systems, backup systems, and UPS.
