Predictive models of Li-ion battery lifetime must consider a multiplicity of electrochemical, thermal, and mechanical degradation modes experienced by batteries in application environments. To complicate matters, Li-ion batteries can experience different degradation trajectories that depend on storage and cycling history of the application environment. Rates of degradation are controlled by fac...

Introduction Batteries with lithium-ion chemistry are the preferred candidate to power hybrid and electric vehicles (HEVs), due to their high power density (up to 150 Wh/kg), short charging time, minimal memory effects and selfdischarge (around 5% per month), and long cycling life [1]. Nonetheless, thermal management of large-scale lithium-ion (Li-ion) batteries during high current charge and d...

Nanoarchitectured electroactive materials can boost rates of Li insertion/extraction, showing genuine potential to increase power output of Li-ion batteries. However, electrodes assembled with low-dimensional nanostructured transition metal oxides by conventional approach suffer from dramatic reductions in energy capacities owing to sluggish ion and electron transport kinetics. Here we report t...

Li-Ion rechargeable battery is one of the most-used rechargeable batteries around the industry of the world. The battery is most used in most electronic devices, electrical cars. But the battery separator is one of the mainly problem that limits the service life. If we can find the way to improve the performance of the battery separator, we can highly increase the service life of the Li-Ion bat...

Here we report an approach to roll out Li-ion battery components from silicon chips by a continuous and repeatable etch-infiltrate-peel cycle. Vertically aligned silicon nanowires etched from recycled silicon wafers are captured in a polymer matrix that operates as Li(+) gel-electrolyte and electrode separator and peeled off to make multiple battery devices out of a single wafer. Porous, electr...

Electric batteries have gained attention with recent developments in the transport sector, especially electric vehicles (EVs) technology and rapid development energy storage sector application to electricity grid. Lithium-ion (LIBs) are particularly popular due their high-power density, high low self-discharge rate, performance. LIB systems also widely utilized extreme operating conditions hars...
