Li-ion batteries have multiple chemistries such as Nickel Manganese Cobalt (NCM), Lithium Cobalt Oxide (LiCoO2), and Lithium Ion Manganese Oxide (LiMnO2). Mostly these batteries are available in standard size which is 18650. These batteries are commonly used in laptops, power tools, robots and specially in electric vehicles. With the use of different advanced technologies these batteries are becoming safer. The nominal Voltage of these battery cells are 3.6, 3.7, and sometimes 3.65 volts.
Melasta uses different chemistries according to the customer demand for Lithium Ion Cells production. We always strive for the best quality by using the international quality standards.
This chemistry is popular choice for laptops, mobile phones, and digital camera and e-bikes due its high specific energy property. This battery made of graphite carbon as anode and cobalt oxide as cathode. Cobalt is the active material which gives properties to the battery.
LiMnO2 battery is known for the characteristics such as fast charging and high current discharging with moderate heat buildup. These batteries can be discharge at 20-30A with very normal thermal buildup. it may discharge at 50A pulse load but it depends on the other specifications as well. These batteries are the best choice for power tools, medical equipment’s, RC toys, Hybrid cars, and electric vehicles.
This Chemistry is the combination of nickel-manganese-cobalt. These batteries can be customized either as power cells or as energy cells. NMC is the popular choice for power tools, e-bikes, and other electric power trains. Because of the combination of blended li-ion and NMC can reduce the cost and make the battery cost effective with very good performance.
Research and Development department has enabled Melasta to produce high quality. Light weight and more power cells in cylindrical shape. We have developed different sizes in cylindrical shape according to the customer demand.
