Low-power-consumption pulse Li-MnO2 battery

Abstract

The invention relates to a low-power-consumption pulse Li-MnO2 battery comprising an anode, a cathode and a non-aqueous electrolyte solution, wherein the anode comprises an active discharging substances including manganese dioxide, graphite powder and acetylene black as well as a binding agent used for binding, wherein the mass ratio of the manganese dioxide to the graphite powder to the acetylene black to the binding agent is (85-90):(1-2):(4-5):(5-6); and the non-aqueous electrolyte solution is a mixed solution of LiClO4, PC (Poly Carbonate), DME (Di Methyl Ether) and DOL with the mass ratio of (3-5):(60-70):(10-20):(20-30). Through adjusting the formula of the anode discharging substances of the battery and improving the formula of electrolyte of the battery, the power output of the battery can be automatically controlled, and better discharging performance and longer discharging time can be displayed on an electric apparatus without power consumption control.

Description

technical field [0001] The invention relates to a battery, in particular to a low power consumption pulse lithium manganese battery. Background technique [0002] In a typical lithium battery, metallic lithium or its alloys are used as the negative electrode active material, metal oxides such as manganese dioxide are used as the positive electrode active material, and an organic electrolyte is further included. Organic electrolytes generally contain non-aqueous solvents and solutes. Non-aqueous solvents such as propylene carbonate (PC), high dielectric constant solvents such as γ-butyrolactone (GBL), 1,2-dimethoxyethane (DME), 3-methyltetrahydrofuran (Me -THF) and other low-boiling and low-viscosity solvents. Supporting salts such as lithium perchlorate (LiClO 4 ), lithium tetrafluoroborate (LiBF 4 )Wait. [0003] The conventional button lithium manganese battery is suitable for small current continuous discharge occasions. Due to the development of low-power pulse dis...

Problems solved by technology

Due to the development of low-power pulse discharge appliances such as LED lamps, new requirements have been put forward for the discharge performance of batteries. The original batteries have relatively high initial discharge power in this type of electrical appliances, but the high power consumption leads to short discharge time. , the appliance stops working within a short period of time
