Abstract: The Coulombic efficiency of metal deposition/stripping can be improved while also preventing dendrite formation and growth by an improved electrolyte composition. The electrolyte composition also reduces the risk of flammability. The electrolyte composition includes a polymer and/or additives to form high quality SEI layers on the anode surface and to prevent further reactions between metal and electrolyte components. The electrolyte composition further includes additives to suppress dendrite growth during charge/discharge processes. The electrolyte composition can also be applied to lithium and other kinds of energy storage devices.

Abstract: A casing includes a base, a trigger switch, an alarm device, and a cover. The base includes a first side plate and a second side plate perpendicular to the first side plate. The trigger switch is mounted to an inner side of the first side plate. A resilient tab is formed on a top of the trigger switch. The alarm device is electrically connected to the trigger switch. The cover covers on a top of the base and deforms the resilient tab down. A recess is defined in a bottom surface of the cover and located between the second side plate and the resilient tab. When the cover is slid away from the second side plate, the recess aligns with the resilient tab. The resilient tab enters the recess and restores. The trigger switch triggers the alarm device to alarm.

Abstract: The Coulombic efficiency of lithium deposition/stripping can be improved while also substantially preventing lithium dendrite formation and growth using particular electrolyte compositions. Embodiments of the electrolytes include organic solvents and their mixtures to form high-quality SEI layers on the lithium anode surface and to prevent further reactions between lithium and electrolyte components. Embodiments of the disclosed electrolytes further include additives to suppress dendrite growth during charge/discharge processes. The solvent and additive can significantly improve both the Coulombic efficiency and smoothness of lithium deposition. By optimizing the electrolyte formulations, practical rechargeable lithium energy storage devices with significantly improved safety and long-term cycle life are achieved. The electrolyte can also be applied to other kinds of energy storage devices.
