About This Product

In the lithium battery business, by mixing metal fibers (AL fibers, CU fibers) in the positive lighter and negative pole layers, we are engaged in the development and commercialization of lithium -ion batteries (LIB) with a high level of internal resistance, increasing capacity, and high cycle. The development of a unique lithium -ion battery with metal fiber mixed into a active material layer started in the 2016 to 2016 strategic base technical advancement support project, and later improvements were added, and the electrodes of storage devices and the manufacturing method were used for lithium -ion batteries using long fibers, short fiber, and powdered methods. We have applied for four international patents regarding the manufacturing method of solid batteries, and has partially patented. Product introduction AL fiber mixture and characteristics of Lib Advantages of adding metal fiber to the active material layer ･ Improvement of impedance characteristics (especially high frequency side) ･ High capacity by thick coating of electrode layer ･ Improvement of cycle characteristics by reducing electrode -layer expansion shrinkage The capacity of the general LIB is about 3cm2 because it depends on the amount of active material application. Thick coating depends on the amount of binder, but it is due to the peeling and chipping of the active material layer. By adding AL fibers, the disadvantages can be greatly improved, and it is about 7 mAh/cm2 per cm2 (0.5c used as a usable current amount). As a result, it can be reduced in the collected foil and separator to be used, and the energy density can be improved. As an example, the general Lib 430mAh/10.1g = 42.6mAh/g, but the Lib1140mAh/16.9g = 67.4MAh/g is about 1.5 times that using a positive layer containing AI fiber. service We have received requests for samples, etc., and requests for explanations.
