Embodiment Construction

[0022] see figure 1 , the present embodiment provides a battery 10 , the structure of the battery 10 is a combination of multiple battery cells 12 , and each battery cell 12 is accommodated in a battery case 14 . The cell 12 includes a positive electrode 20 , a negative electrode 22 and a separator 24 . The diaphragm 24 is a ceramic polyolefin composite diaphragm or a polyvinyl chloride diaphragm, and is arranged between the positive electrode 20 and the negative electrode 22 . In addition, a piece of the separator 24 is also disposed between two adjacent battery cells 12 . In this way, each battery cell 12 forms a laminated structure in which the separator 24 , the negative electrode 22 , the separator 24 and the positive electrode 20 are connected in sequence. Secondly, the battery case 14 may optionally be filled with a polymer gel electrolyte (not shown).

[0023] The positive electrode 20 is composed of a positive electrode active material 200 , a binder (not shown), a...

Abstract

The invention is a graphene metal power battery, comprising a combination of a positive pole, a negative pole, a plurality of composite diaphragms and a battery casing; wherein the positive pole comprises a positive pole active material and a positive pole current collector; the negative pole comprises a negative pole active material and the negative electrode collector. The positive electrode active material is selected from one of aluminum-coated nickel-cobalt lithium manganate or lithium-coated nickel-cobalt-aluminum mixed with lithium manganate or alkene silicon-coated lithium manganate, or graphite carbon material and metal oxide Composite material made; the positive current collector adopts aluminum foil coated with silicon three-dimensional graphene and benzene ring hydrocarbon chlorine; the negative electrode active material is selected from graphite carbon material or a composite material made of graphite carbon material and metal oxide; the The negative current collector is made of copper foil coated with silicon three-dimensional graphene and benzene ring hydrocarbons. This overcomes the shortcomings of traditional lithium batteries such as low voltage, low energy, low discharge efficiency, short service life, poor safety, and unstable battery structure, as well as the effect of improving the heat-resistant temperature of the positive and negative electrodes.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a graphene metal power battery. Background technique [0002] Currently, there are various types of batteries in the market, such as primary batteries and secondary rechargeable batteries. In terms of composition, there are lead-acid batteries, nickel-metal hydride batteries, nickel-cadmium batteries, and lithium batteries (lithium cobalt oxide, lithium manganese oxide, and lithium iron phosphate). Various types of batteries can be used in electric tools, electric bicycles, electric motorcycles, and electric vehicles. As far as energy storage is concerned, batteries have small capacity, low power, and low efficiency. Therefore, it is necessary to use multiple batteries in parallel and / or in series to increase power and capacity, thereby increasing the usable time of the product. [0003] Lithium-ion batteries are mainly composed of electrodes, separators, and electrolytes. A...
