Title:
SECONDARY BATTERY OF ZINC-LITHIUM-MANGANESE WATER SYSTEM AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/190584
Kind Code:
A1
Abstract:
Disclosed are a secondary battery of a zinc-lithium-manganese water system and a preparation method therefor, wherein same fall within the battery manufacturing field. The secondary battery of a zinc-lithium-manganese water system comprises a positive electrode, a negative electrode, an electrolyte and a separator between the positive electrode and the negative electrode. An active material of the positive electrode is a manganese lithium oxide material; an active material of the negative electrode is zinc or a zinc compound; and the electrolyte is a neutral aqueous solution containing a lithium salt and a zinc salt. The secondary battery is characterized in: the separator being an ionic polymer membrane composed of acrylate polymer colloidal particles with sulfonate groups on the surface. The secondary battery of a zinc-lithium-manganese water system has a stable performance and a long cycle life, can be industrially produced, and has a uniform electric field inside the battery. The secondary battery of a zinc-lithium-manganese water system solves the problem that the dendrite growth and the side reactions related thereto result in non-practicability of a battery, such that the zinc-lithium-manganese battery has the characteristics of a high energy density, long cycle life, high safety and low cost; and the scale industrialization of a secondary battery of a zinc-lithium-manganese water system can be realized, and the development of same in fields such as electric vehicles and power energy storage can be promoted.
