Although smartphones have developed rapidly in the past decade, with increasing performance and specifications, the battery life has not made much progress. Although cell phone manufacturers have improved energy consumption or charging efficiency to increase battery life, they still cannot improve the problem of battery life decreasing with the passage of time.
However, according to the foreign media “Sam Mobile” reported that researchers from Japan’s Hokuriku Advanced University (JAIST) discovered a new material that is claimed to be able to make the battery capacity drop only 5% in five years, significantly extending the battery life.
The current lithium-ion batteries used in cell phones use a material called “polyvinylidene fluoride (PVDF)” to bind the negative terminal inside, but the performance is not ideal, and only 500 cycles of charging will reduce the battery capacity by 35%, which is the main reason why users feel the battery life decreases after two years of use.
Researchers at Hokuriku Advanced University have discovered a new adhesive material to replace polyvinylidene fluoride, called “bisimino-ac-naphthoquinone-p-phenylene (BP)”, which can effectively extend battery life by maintaining 95% of its original capacity for five years and allowing up to 1,700 cycle charges.
This technology will be widely used in smartphones, tablets, laptops and even wearable devices, and can also be applied to electric vehicles or home appliances, and can increase the wattage of fast charging, so that battery life no longer becomes a headache for manufacturers.
