Systems and methods include a cardiac device advisory management platform to receive and distribute data related to advisory notification(s) for an implanted cardiac device. Advisory notification data includes a device identifier and / or a lead identifier corresponding to the advisory notification. Upon receiving the advisory notification data, the clinic matches the device identifier and / or the lead identifier with patient data for patients enrolled with the clinic. One or more action indicators for various workflow procedures are generated and presented at a clinic user interface (UI) of the clinic device. Clinician inputs are received via the clinic UI to perform steps in response to the advisory notification, such as reviewing patient information, scheduling an in-office visit, and / or sending a notification to a patient device. A clinic behavior analysis is performed on the clinician inputs to generate information regarding the impact of the advisory notifications on the clinic workflow procedures.

The invention discloses an electrolyte, a battery and application thereof. The electrolyte comprises an aprotic organic solvent and lithium salts, wherein the lithium salts comprise high-stability organic lithium borate and high-ionic-conductivity (greater than or equal to 8mS / cm) lithium sulfimide. Wherein the high-conductivity salt is responsible for improving lithium ion transport kinetics and promoting rapid embedding of lithium ions into the positive electrode, and the organic lithium borate salt plays a dual protection role by virtue of excellent thermal stability and chemical stability, on one hand, a stable film is formed on a positive electrode interface, structural stress and damage are relieved, and vanadium dissolution is directly inhibited; on the other hand, the gas production risk of the electrolyte is reduced through the thermal stability, the internal pressure of the battery is controlled, and the vanadium dissolution driving force is indirectly reduced. The two components cooperate with each other, so that the structural integrity of the positive electrode material is protected, the improved electrolyte component reduces the increase of the internal resistance of the battery during the discharging period of the battery, and the safety and reliability of the battery in the implantable heart equipment are improved.
