Problems solved by technology

However, graphite or carbon materials are usually used as the negative electrode in soft-pack lithium-ion batteries. Since it is easy to contain impurities of natural components, the lithium ions in the carbon material negative electrode after charging will form complexes with impurities, resulting in lithium-ion batteries. The overall impedan

Embodiment Construction

[0015] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0016] The lithium-ion battery negative electrode material additive provided by the present invention is a mixture of various biochemical molecules, and the source of the additive is produced by one or more of lactic acid bacteria, yeast, photosynthetic bacteria and Gram-negative bacteria through metabolic pathways Metabolites, the metabolic pathways include aerobic respiration, anaerobic respiration, photosynthesis and glycolysis. The main metabolic pathways and metabolites of the above four microorganisms are shown in Table 1.

[0017] Table 1

[0018]

[0019]

[0020] Note: During the metabolic process, the metabolites ATP and ADP will exist at the same time, so ATP* represents the mixture of the two.

[0021] The main products after the above-mentioned metabolism are acetaldehyde, ethanol, lac...

Abstract

The invention relates to a lithium ion battery negative electrode material additive, a lithium ion battery and a negative electrode material thereof. The additive comes from a metabolic product generated by at least one of lactic acid bacteria, yeast, photosynthetic bacteria and gram negative bacteria through metabolism, and the generated metabolic product is a compound, the tail end or branched chain of which has a phosphate ion or an acetate ion. Adding of the additive provided in the invention in a lithium ion battery negative electrode material can effectively mitigate self discharge during lithium ion battery storage and high-temperature heat due to overcharge without affecting the original electrical performance of a lithium ion battery, and can maintain good battery cycle life.

Description

technical field [0001] The invention relates to a lithium ion battery, in particular to a lithium ion battery negative electrode material additive using a biochemical molecular formula, and a lithium ion battery and negative electrode material using the additive. Background technique [0002] Batteries can be mainly divided into Primary Battery and Secondary Battery. The primary battery converts chemical energy into electrical energy, and cannot convert electrical energy into chemical energy through charging. Therefore, once the chemical substances inside the battery Disappeared, that is, can not continue to supply power, such as mercury batteries, carbon-zinc batteries, alkaline batteries, etc.; secondary batteries can continue to repeat through charging, such as nickel-cadmium batteries, nickel-metal hydride batteries and lithium-ion batteries. [0003] In addition, in recent years, secondary batteries can be widely used in a variety of portable electronic products, such a...
