Abstract: The invention discloses a zinc organic battery having a container. The container contains a positive electrode active material, a positive electrode current collector, an organic solvent, a zinc negative electrode, and an aqueous electrolyte. The organic solvent and the aqueous electrolyte are not miscible and are layered due to different densities. The positive electrode active material has a redox activity, and has the two forms of an oxidized state and a reduced state. If the positive electrode active material itself is a liquid and is difficult to be dissolved in the aqueous electrolyte, then the organic solvent may be omitted. The positive electrode active material itself doubles as the organic solvent and is layered with the aqueous electrolyte. The zinc negative electrode is immersed in the aqueous electrolyte and is not in contact with the organic solvent. The aqueous electrolyte is an aqueous solution containing a zinc salt.

Abstract: The present invention discloses a method and device for monitoring state of charge and state of health of a battery, and relates to the technical field of battery. The method comprises: firstly, passing ultrasonic waves through a lithium-ion battery in different SOCs at different charging and discharging currents to obtain acoustic parameters, and then establishing respective corresponding relationships between the acoustic parameters and the lithium-ion battery SOC and SOH; and secondly, monitoring the acoustic parameters of a lithium-ion battery, and then estimating SOC and SOH of the lithium-ion battery by combining the monitored acoustic parameters with the respective corresponding relationships between the acoustic parameters and the lithium-ion battery SOC and SOH. The invention further provides a device implementing the above method. The method and device can monitor the battery SOC and SOH in a brand new way different from the electricity parameter measurement. The method can effectively monitor SOC and SOH of lithium-ion batteries of various types and shapes and thus has a good application prospect.
