Dangers of ultrafast charging of mobile devices

By their design, mobile devices, especially smartphones are always on, and with today‚Äôs need for high speed data communication via mobile base stations providing 4G data and voice services, energy consumption is significantly higher than feature phones of the previous mobile telecommunications era. Thus, battery capacity and energy consumption became primary points of consideration in … More Dangers of ultrafast charging of mobile devices

High surface area to volume ratio electrodes in lithium sulphur batteries

Lithium ion batteries has the highest energy density of commercially available portable rechargeable batteries. But, in practical use, numerous problems concerning safety, progressive loss of charge capacity with increase in charge cycles, and inadequate energy density for high power consuming smartphones, tablets and laptops, motivated the development of new generations of lithium ion batteries with … More High surface area to volume ratio electrodes in lithium sulphur batteries

Understanding the precision engineering aspects of lithium ion batteries

Since their commercial application by Sony in 1990, lithium ion batteries have progressively replaced other rechargeable batteries such as nickel metal hydride batteries, which in the 1990s was the main power pack for remote controlled cars etc. Compared to other types of rechargeable batteries based on different chemistries, the lithium ion battery has the highest … More Understanding the precision engineering aspects of lithium ion batteries
