A maintainable lithium ion battery and a maintenance method thereof

Abstract

A maintainable lithium ion battery is disclosed, which includes a housing, electrode post, negative plate, a positive electrode sheet, a separator and an electrolyte, wherein at least one of the electrode posts is provided with an exhaust hole conductive to the inside of the battery in the axial direction of the column thereof, the outer surface of the electrode post is provided with a screw thread, and the electrode post is connected with an outer nut which is matched and screwed with the electrode post, and the outer nut is used as a connection terminal of the lithium ion battery; A seal gasket is also arranged between the outer nut and the electrode post. The invention further discloses a maintenance method of a maintainable lithium ion battery. The lithium ion battery provided by the invention and the maintenance method thereof not only effectively prolong the service life of the lithium ion battery, but also greatly reduce the calendar life cost of the battery, so that the lithiumion battery industry realizes the benign development, and at the same time, the real cascade utilization in the technical field of the lithium ion battery is realized.

Description

technical field [0001] The invention relates to the technical field of lithium-ion batteries, and more specifically relates to a maintainable lithium-ion battery and a maintenance method thereof. Background technique [0002] As a new type of chemical energy storage device, lithium-ion batteries have good cycle life, energy saving, environmental protection, reusability and high safety. They can replace lead-acid batteries and are widely used in consumer goods, vehicles and energy storage markets, completely changing the current There are conditions of using gasoline, diesel, natural gas and other non-renewable energy sources, which have broad development prospects and social needs. Based on this, lithium-ion batteries are currently the fastest growing battery chemistry. Lithium-ion batteries are basically used in the consumer goods market, and the application range of lithium-ion batteries is also developing from miniaturization to large-capacity, such as power batteries fo...

Problems solved by technology

[0004] In addition, there are currently some maintainable batteries, but they are provided with a one-way valve on the battery casing. This structure can only exhaust, and cannot replenish or replace the electrolyte, and the structure of the one-way valve is limited due to limited The air pressure range is too narrow, it is difficult to achieve the ideal exhaust effect, and because the one-way valve is often opened, the exhausted gas contains strong acid, corrodes the electronic equipment around the battery, and even causes a short circuit
