Novel energy-gathering sheet lithium battery

Technical Field

The utility model belongs to the technical field of the lithium cell, especially, relate to a novel gather ability slice lithium cell.

Background

A "lithium battery" is a type of battery using a nonaqueous electrolyte solution with lithium metal or a lithium alloy as a positive/negative electrode material. Lithium metal batteries were first proposed and studied by gilbertn. lewis in 1912. In the 70 s of the 20 th century, m.s.whitetingham proposed and began to study lithium ion batteries. Because the chemical characteristics of lithium metal are very active, the requirements on the environment for processing, storing and using the lithium metal are very high. With the development of scientific technology, lithium batteries have become the mainstream. Lithium batteries were used in cardiac pacemakers in the earliest days. The lithium battery has the advantages of extremely low self-discharge rate, mild discharge voltage and the like, so that the pacemaker implanted into a human body can operate for a long time without recharging. Lithium batteries generally have a nominal voltage of greater than 3.0 volts and are more suitable as integrated circuit power supplies. Manganese dioxide batteries are widely used in calculators, digital cameras and watches. Lithium batteries can be broadly classified into two types: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain lithium in the metallic state and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996, and the safety, specific capacity, self-discharge rate and cost performance of rechargeable batteries were all superior to those of lithium ion batteries. In general, a lithium metal battery uses manganese dioxide as a positive electrode material, lithium metal or an alloy metal thereof as a negative electrode material, and a nonaqueous electrolyte solution. In general, a lithium ion battery uses a lithium alloy metal oxide as a positive electrode material, graphite as a negative electrode material, and a nonaqueous electrolyte.

However, the lithium ion batteries commonly used in the market at present have large mass, large volume and small energy density, and are deficient in use and carrying; meanwhile, liquid electrolyte is used inside lithium ion batteries commonly used in the market, so that explosion is easily caused by electrolyte leakage, and more safety problems are caused.
