Lithium batteries have the advantages of high energy density, long cycle life, low self-discharge rate, no memory effect and environmental protection, and have broad application prospects in the field of electric energy storage. Lithium battery technology currently has different types such as lithium cobaltate, lithium manganate, lithium iron phosphate, and lithium titanate. Coolnet has been committed to the research on improving the volume specific energy, weight specific energy, battery consistency and safety of batteries. Through years of research and development, we have successfully developed high-performance aluminum case 10Ah, 20Ah, plastic case 20Ah, 40Ah, 50Ah, 60Ah, 100Ah single lithium iron phosphate battery, and have been widely used in the market.
