Ready for the next great invention in the battery market? This time, scientists from JAIST, the Japanese Institute of Science and Technology, have developed an example of a durable lithium-ion battery that is able to withstand up to 5 years of use without significant energy loss.
Japanese scientists found that the new material (with English. bis-imino-acenaphthenequinone-paraphenylene) can significantly enrich the positive electrode as a binding material. It is a substance that is used to coat the electrode and helps to prevent the electrode material from breaking down and degrading through continuous charging and discharging cycles.

Typically, lithium-ion cells that build battery packs use graphite anodes coated with polyvinylidene fluoride (PVDF) with a life of approximately 500 charge cycles at full (rated) capacity. These after half a thousand cycles limited the capacity to 65%.
According to JAIST’s research, the new anode coating material is able to withstand 1,700 charging cycles, keeping the battery capacity at 95%. Translating this into practical use, in the case of a smartphone charged at least once a day, it means almost 5 years of full battery efficiency.
