In what different ways can a EV lithium ion battery be used in second life?5 answersElectric vehicle lithium-ion batteries can be repurposed in various ways for a second life. One approach involves utilizing retired batteries for grid-scale energy storage, residential energy storage, EV charging stations, and telecommunications backup power. Another method is to reuse whole packs of retired batteries, which has been found to be more environmentally beneficial than using only cells or modules. Additionally, repurposing retired Li-ion batteries for energy arbitrage applications in power systems has shown promising financial returns, especially for lithium iron phosphate (LFP) batteries compared to lithium nickel manganese cobalt oxide (NMC) batteries. Furthermore, potential second-life applications include automated guided vehicles (AGVs) and industrial energy storage systems (ESSs) with renewable firming purposes, indicating a broad spectrum of opportunities for second-life battery use.
Why lithium metal is used in batteries?5 answersLithium metal is utilized in batteries due to its potential to significantly enhance energy density. Despite being challenging to commercialize, lithium metal batteries (LMBs) offer high specific capacities and energy densities, making them attractive for applications like electric vehicles and grid storage. Research focuses on overcoming obstacles such as dendritic growth and parasitic reactions to advance LMB technology towards large-scale commercialization. Understanding the fundamental science of lithium, including its structural, energetic, and electrochemical properties, is crucial for improving lithium anodes and addressing issues like lithium dendrite formation. Additionally, investigations into the solid electrolyte interphase (SEI) formation and ion diffusion mechanisms aim to enhance the performance and safety of lithium metal batteries.
How ester can be used in lithium batteries performance?4 answersEsters can be used in lithium batteries to improve their performance. The addition of esters as co-solvents to the electrolyte can enhance low-temperature performance and rate capability of the batteries. For example, the ester methyl acetate (MA) has been found to have a positive impact on the conductivity and viscosity of the electrolyte, leading to improved battery performance. Additionally, the use of ester-based electrolytes, such as linear carboxylic esters and fluorinated carboxylic acid esters, has been shown to enhance the ionic conductivity and compatibility of the electrolyte with the lithium metal anode, resulting in stable cycling performance at room temperature and even at ultra-low temperatures. Furthermore, the solvation behavior of the ester-based electrolyte can be regulated to improve the properties of the battery, such as the formation of a protective solid electrolyte interphase (SEI) film on the anode, which effectively protects the lithium metal and suppresses voltage decay and dissolution of transition metals.
