Challenges and opportunities toward long-life lithium-ion
It shows that the mainstream commercial LFP batteries for ESS currently meet the standard of 5000 cycles of cycle life and a 10-year calendar life. Meanwhile, mainstream commercial NCM batteries with moderate to low nickel content for EV power batteries achieve a standard of 1000∼3000 cycles of cycle life and an 8-year calendar life.

Discovery may lead to longer-lasting, longer-range EV batteries
Rechargeable batteries lose stored energy when they''re not being used because an idle battery undergoes internal chemical reactions that slowly drain its energy. This "self-discharge" process can eventually consume active ingredients in the cathode, where the electron-spent lithium ions collect while the device is in use. This shortens a battery''s life
