Abstract
A rechargeable lithium-ion battery disclosed herein comprises a positive electrode with a positive electroactive material that in a charged state comprises lithium iron (II) orthosilicate (LiFeSiO) and in a discharged state comprises FeSiOor LiFeSiO. A negative electrode comprises phosphorene. A separator is disposed between the positive electrode and the negative electrode. An electrolyte has an organic solvent especially containing ether-based organic solvents and a lithium salt that provides a conductive medium for lithium ions to transfer between the positive electrode and the negative electrode. Such a rechargeable lithium-ion battery provides advantageous power delivery, long driving ranges, and fast charge to enhance widespread use of batteries, especially in vehicles. Furthermore, lithium plating can be minimized or avoided, even at low temperature charging. Methods of recharging a rechargeable lithium-ion battery at low temperatures are also disclosed.
