REFERENCE ELECTRODE WITH THERMOMETER FUNCTION, LITHIUM-ION SECONDARY BATTERY INCLUDING REFERENCE ELECTRODE WITH THERMOMETER FUNCTION, LITHIUM-ION SECONDARY BATTERY SYSTEM INCLUDING REFERENCE ELECTRODE WITH THERMOMETER FUNCTION, AND LITHIUM-ION SECONDARY BATTERY CONTROL METHOD

摘要

The purpose of the present invention is to prevent a solution, such as an electrolyte, present inside a secondary battery from leaking when a sensor is introduced into the secondary battery. A reference electrode with a thermometer function has a temperature measurement unit and a reference electrode function unit. The temperature measurement unit measures the temperature of a lithium-ion secondary battery having a positive electrode and a negative electrode. The reference electrode function unit detects the voltage levels at the positive and negative electrodes and has any one or more of lithium manganese spinel, a lithium alloy, lithium titanate, phosphoric acid transition metal lithium, and metal lithium.
