Battery management system monitors and mitigates the operation of battery cells and stacks and is important for battery safety and reliability. This paper presents a dual-objective optimal charging strategy for two types of Li-ion batteries, which considers the conflict objectives of charging time and charging loss. The battery models developed in a prior research are used in the charging optim...

myo-Inositol-1-phosphatase has been partially purified from bovine brain. The enzyme has a molecular weight of about 58,000. Both L-myo-inositol 1-phosphate and D-myo-inositol 1-phosphate are hydrolyzed by the enzyme as well as (-)-chiro-inositol 3-phosphate and 2'-AMP. Triphosphoinositide is not a substrate. The phosphatase is completely dependent on Mg2+, which has a Km of 1 mM. Calcium and m...

In this paper we report on a lithium ion battery (LIB) based on improved olivine lithium iron phosphate/carbon (LiFePO4/C) as cathode material and LiNa0.02K0.01FePO4/C  synthesized by sol-gel method and TiO2 nanotube arrays (TNAs) with an anatase phasesynthesized through anodization of Ti foil as an anode electrode. Crystallographic structure and surface morphology of the cathode and anode mate...

Current electrolytes for lithium batteries are usually composed of at least two chemical compounds, an organic solvent such as a cyclic carbonate and salt LiPF6. Here, the concept using single-component electrolyte is demonstrated in based on new borate ionic liquids room temperature. The design this class (LiILs) asymmetrically substituted central tetracoordinate boron atom with oligoethylene ...

Thermal runaway (TR) of lithium-ion batteries (LIBs) has always been the most important problem for battery development, and TR characteristics large LIBs need more research. In this paper, thermal propagation (TRP) behavior changes three lithium iron phosphate (LFP) (numbered 1 to 3) under different states charge (SOCs) were studied. The main parameters discussed include temperature, temperatu...

The need to recover critical elements from lithium-ion batteries is undisputed. further development of cathode materials and the move towards cheaper alternatives make it necessary adapt corresponding hydrometallurgical recycling processes. In best case, however, a process so flexibly structured designed that can be used for variety with different compositions. leaching nickel manganese cobalt ...
