Low-cost self-assembled electrode coating as a separator for batteries

BackgroundA separator in a rechargeable battery serves as a physical barrier between the two electrodes, allowing ionic transport with a liquid electrolyte while blocking electrical transport, preventing a short circuit. The separator is the most expensive component by weight of a commercial lithium-ion battery. Additionally, it is the least researched...

High-capacity, surface-modified layered oxide cathodes with low irreversible capacity loss for lithium-ion batteries

BackgroundLithium-ion batteries have become the chemistry of choice for portable electronic devices such as laptops and cell phones because they offer much higher energy density compared to other rechargeable systems. However, lithium-ion batteries currently use layered lithium cobalt oxide as the cathode (positive electrode) material, only use 50%...
