Abstract

The invention discloses a lithium-chromium rechargeable battery and a manufacturing method thereof. The lithium-chromium rechargeable battery comprises a battery positive electrode made of lithium chromium oxide, a battery negative electrode made of boron oxide or an aluminum-nickel alloy, and fluorine is injected into an electrolytic solution. Thiamine organic solution, on the basis of traditional storage of electrons, also through the synergistic reaction of lithium chromium oxide and boron oxide or aluminum nickel alloy in the electrolyte, lithium chromium oxide performs reversible electrochemical reaction on the surface of boron oxide or aluminum nickel alloy The reaction further stores electrons, thereby greatly increasing the capacity of the battery, and improving the high-current characteristics of the battery, thereby improving the cycle life of the battery.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a lithium-chromium rechargeable battery with high energy density, low self-discharge rate and long cycle life and a manufacturing method thereof. Background technique [0002] At present, energy conservation and emission reduction have become an inevitable requirement for my country's economic and social development. At the same time, future social development still requires high-capacity and long-life rechargeable batteries to support it. For example, consumer electronics, electric vehicles, aerospace and other fields all require high-capacity batteries. [0003] The existing rechargeable nickel ion battery is a rechargeable battery using manganese oxide material as the positive electrode active material, nickel as the negative electrode active material, and an aqueous solution containing nickel ions as the electrolyte. Common rechargeable nickel-ion batteries use manganese dioxide as t...
