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 discloses a graphene metal power battery. The graphene metal power battery comprises a combination of a positive electrode, a negative electrode, a plurality of composite diaphragms anda battery shell, wherein the positive electrode comprises a positive electrode active material and a positive electrode current collector; the negative electrode comprises a negative electrode activematerial and a negative electrode current collector; the positive electrode active material is selected from one of aluminum-coated lithium nickel cobalt manganate or lithium-coated nickel cobalt aluminum, or one of mixed lithium manganate or graphene silicon-coated lithium manganate, or a composite material prepared from a graphite carbon material and metal oxide; the positive electrode current collector adopts a silicon-coated three-dimensional graphene and benzene ring carbon hydrogen chlorine aluminum foil; the negative electrode material is selected from a graphite carbon material or a composite material prepared from the graphite carbon material and metal oxide; and the negative electrode current collector adopts a silicon-coated three-dimensional graphene and benzene ring carbon hydrogen chlorine copper foil. Therefore, the shortcomings of low voltage, low energy, low discharge efficiency, short service life, poor safety and instable battery structure of the conventional lithiumbattery are overcome, and the heat-resistant temperatures of the positive electrode and the negative electrode are improved.

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...
