Problems solved by technology

But in fact, lithium-ion batteries will also attenuate. In addition to process problems such as liquid leakage and gas leakage that lead to loss of raw materials, its deep material-level attenuation has always been a mystery.

Embodiment Construction

[0031] It should be noted that, in the case of no conflict, the implementation modes in the present application and the features in each implementation mode can be combined with each other.

[0032] Hereinafter, the present application will be described in detail with reference to the accompanying drawings and in combination with embodiments.

[0033] Traditional lead-acid batteries are repaired using pulses of several thousand hertz, but this frequency cannot meet the needs of lithium batteries. Lithium ions have reached atomic-scale particles, and must reach a megahertz-level resonant pulse frequency. At the same time, it must be combined with the sieve effect of charge-discharge synchronization to break the micro-scale SMI film. Therefore, for power lithium battery (referred to as lithium battery) repair, it is necessary to achieve battery repair under certain conditions. The core technology is to induce atomic-scale resonance and realize high-frequency pulse repair. Howe...

Abstract

The invention discloses a power lithium battery barrier breaking machine and a power lithium battery charging method. The power lithium battery barrier breaking machine comprises a direct-current power supply module and a power lithium battery high-frequency charging and discharging module. The working frequency of the power lithium battery high-frequency charging and discharging module is greater than or equal to 1 million Hz; and the power lithium battery high-frequency charging and discharging module repairs the power lithium battery through charging and discharging. The lithium battery attenuation problem caused by the lithium battery crystal dendrites can be successfully solved, and the service life of the lithium battery is prolonged.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to a power lithium battery barrier breaker and a power lithium battery charging method. Background technique [0002] Battery breaking is a battery repair method based on the resonance principle. This technical method is also used when repairing traditional lead-acid batteries, such as using pulse charging to repair lead-acid batteries. In view of the experience of the predecessors, after the large-scale application of lithium batteries, people also expected to use battery breaking technology to repair lithium batteries, but they did not succeed. Since the lithium battery adopts a fully enclosed design and cannot be refilled, the industry consensus believes that the life decay of lithium batteries is an irreversible phenomenon. [0003] Lithium-ion batteries are a great invention, once thought to have an infinite life in theory. But in fact, lithium-ion batteries will also decay. ...
