Extended life cycle assessment reveals the spatially-explicit water scarcity footprint of a lithium-ion battery storage

Complementarities of water-focused life cycle assessment and water footprint assessment.

T recent past has shown two parallel developments: the water resources community discovered the relevance of supply chain thinking for water resources management and freshwater allocation, while the life cycle assessment (LCA) community recognized the importance of water use and included those related impacts in LCA studies. The water footprint concept was introduced by Arjen Hoekstra as an ind...

Cycle Life Modeling of Lithium-Ion Batteries

A first-principles-based charge-discharge model was developed to simulate the capacity fade of Li-ion batteries. The model is based on the loss of active lithium ions due to solvent reduction reaction and on the rise of the anode film resistance. The effect of parameters such as exchange current density, depth of discharge ~DOD!, end of charge voltage, film resistance, and the overvoltage of pa...

Numerical investigation of the parameters of a prismatic lithium ion battery under load for electrical vehicle

Electric vehicles and hybrid electric vehicles are a suitable alternative for vehicles with hydrocarbons fuels to reduce pollution and fossil resources. The batteries operate as the driving force for these vehicles. One of the most critical parameters of the battery is computing the state of charge (SOC). The best range for SOC of lithium-ion battery is between 20% and 90%, and charging and dis...

Modeling The Lithium-ion Battery

Porous doped silicon nanowires for lithium ion battery anode with long cycle life.

Porous silicon nanowires have been well studied for various applications; however, there are only very limited reports on porous silicon nanowires used for energy storage. Here, we report both experimental and theoretical studies of porous doped silicon nanowires synthesized by direct etching of boron-doped silicon wafers. When using alginate as a binder, porous silicon nanowires exhibited supe...
