ProLogium showcased the world’s first flexible FPC lithium-ceramic battery (FLCB) during Computex 2014. This breakthrough product is almost as flexible as a sheet of paper, breaking through all the limitations of lithium batteries such as thickness, weight, and flexibility. ProLogium states that its flexible FLCB is superior in quality and performance than similar technology from LG and Apple.
FLCB uses flexible printed circuits (FPC) as battery substrate and packaging material, breaking through the limits of the traditional manufacturing process by using printing and coating methods to manufacture the bendable battery. This product is the true form of a bendable or flexible battery. Previously, LG’s bendable smartphone also uses a form of bendable battery. However, the curvature of the battery is molded and unable to be physically bent or twisted. ProLogium’s FLCB is able to be freely manipulated. Due to its powdered ceramic structure material, the batteries will not leak like traditional lithium batteries, and are not subjected to the dangers of explosions and catching fire. Compared to liquid lithium batteries of the same size and capacity, FLCB batteries are only 0.2-0.45mm in thickness. These batteries can reach 1mx 1m in size, but weigh as much as a sheet of paper and can be rolled up to save space.
The capacity of ProLogium’s FLCB has already reached up to 90 percent of regular lithium batteries. The company has hopes that its upgraded FLCB can reach up to 1.5 times the capacity of regular lithium batteries by the second half of 2014, and enter production stage as early as first quarter of 2015. ProLogium explains that the patented bendable battery technology of Apple uses micro particles of lithium battery to achieve bendability, but it cannot be considered a breakthrough. What can be sure is FLCB has a bright future in many applications such as wearable technology, smartphones, and automobiles.
Visitors who have seen the FLCB in action are surprised by its performance and believe it is a product worth noting. However, it has not yet been used for any large-scale commercial purposes after hitting mass production. Currently, only a cell phone charging case company for the HTC One is using the FLCB in its product. However, the case uses five layers of the battery but does not utilize the flexible properties of the FLCB. Employees at ProLogium state that since the FLCB is a first in the industry, it is very expensive, and therefore unlikely for it to enter the consumer market in the short term, though it is likely to lower the price of traditional lithium batteries by two to three times.
