Lithium battery

Abstract

The invention discloses a lithium battery. The lithium battery comprises a battery shell, the outer surface of the battery shell is fixedly sleeved with a storage bag, a lampshade is fixedly embeddedinto the front surface of the battery shell, a telescopic rod is movably embedded into the battery shell, and a positive binding post is fixedly installed on the upper surface of the battery shell; anegative binding post is fixedly installed at the position, symmetrical with the positive binding post, of the upper surface of the battery shell, a display screen is fixedly installed at the position, between the positive binding post and the negative binding post, of the upper surface of the battery shell, and a USB interface is formed in the position, in front of the display screen, of the upper surface of the battery shell. The lithium battery disclosed by the invention can be conveniently carried for a long distance by a user, and a storage bag can be stably placed on some uneven groundsin the field, so that the adaptability and the protection performance of the lithium battery are better, and the light gathering cover can be adjusted at a free angle to finish illumination, so that the lithium battery is more flexible in use.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to a lithium battery. Background technique [0002] Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batteries, the fifth generation of rechargeable batteries, were born in 1996. Safety, specific capacity, self-discharge rate and performance-price ratio are all superior to lithium-ion batteries. Due to its own high technical requirements, only a few companies in a few countries are producing this lithium metal battery. The earliest application of lithium batteries In cardiac pacemakers, lithium batteries have the advantages of extremely low self-discharge rate and gentle discharge voltage, which enable the pacemaker implanted in the human body to operate for a long time without recharging. Lithium batteries generally have a nominal...

Problems solved by technology

[0003] However, there are certain disadvantages in the use of lithium batteries at this stage. It is inconvenient to carry during some long-distance field work during use, and the ground in the field is uneven, so that the lithium battery cannot be placed vertically on the ground. If it is accidentally poured into the water flow In addition, when walking at night, the LED light tube inside the lampshade can only be used for rear lighting, and other lighting tools are required for viewing in front or other directions. The use of lighting is very troublesome, which is not conducive to the rapid completion of tasks by the user, and is not conducive to timely ascertaining the surrounding terrain and environment, etc.
