Embodiment Construction

[0010] The present invention will be further elaborated below by taking a button lithium battery as an example according to the accompanying drawings.

[0011] like figure 1 and figure 2 As shown, in this embodiment, a storage lithium battery 100 is a cylindrical button battery, which includes a casing, an electrolyte (not shown) inside the casing, a valve 30 and a battery cell including battery active materials. The valve 30 is fixedly connected with the casing, and isolates the electrolyte and the cell in two spaces that are not connected to each other. The strength of the valve 30 requires that under a predetermined acceleration, the electrolyte can break through the valve, instantly infiltrate the cell and activate the battery.

[0012] The valve 30 can be made of metal material, hard plastic or tempered glass with certain strength and no chemical reaction with the electrolyte according to the battery type and activation conditions. The metal material can be metals or ...

Abstract

The invention relates to a reserve type lithium battery which comprises a shell, an electric core and electrolyte, wherein the electric core and the electrolyte are positioned in the shell; and the reserve type lithium battery also comprises a valve which is fixed in the shell and used for isolating the electric core from the electrolyte. The electrolyte breaks through the valve and soaks the electric core at preset acceleration. The reserve type lithium battery of the invention has simple and compact structure and simple and easy manufacture process. The valve is directly fixed on the shell and occupies less internal space of the battery, and battery capacity is basically free from influence; and the invention is convenient to improve battery design capacity and shorten battery integral volume and meets the miniaturized and light-weight development tendency of the traditional battery. The battery can be in a shape of column, square, coin, button, and the like, and the reserve type lithium battery can be used as a single fuse and various ammunition fuses.

Description

technical field [0001] The invention relates to a lithium battery, in particular to a reserve lithium battery. Background technique [0002] The reserve lithium battery is also called the activation battery. In the reserve state, the active material of the battery is not in direct contact with the electrolyte, so there is no electrical energy output and no energy loss occurs. When in use, the electrolyte is released by the power source to activate the battery. Therefore, it has the advantages of long storage time, maintenance-free, and high specific energy, and is widely used in important equipment such as fuzes. [0003] Existing reserve lithium batteries, such as the U.S. Patent Application "A Reserve Battery and Its Use" (Reserve Battery and Its Use, publication number US 2004 / 0197640, published on October 7, 2004), the disclosed reserve battery, Consists of a sealed glass bottle for storing electrolyte, a support structure for securing the glass bottle and activation ...
