Why does the capacity of lithium-ion batteries decrease?
From large-scale electric vehicles to small electronic products like computers and mobile phones, battery life has always been a major concern for consumers. Even the recent Samsung Note 7 explosion incident has been attributed by some experts to the developer's excessive pursuit of battery life while neglecting battery safety hazards. Samsung is not the only company troubled by battery issues; recently, the Microsoft Surface Pro 3 has also experienced battery problems. Some users have reported that the battery life of the Surface Pro 3, which uses an LGC battery, has been significantly reduced after the upgrade.
Lithium-ion batteries are the fastest-growing type of rechargeable battery after nickel-cadmium and nickel-metal hydride batteries. The application of lithium-ion batteries largely depends on the stability of their charge-discharge cycles. Like other rechargeable batteries, capacity decay is inevitable during cycling.
