A new variety of research at home and abroad - new lithium battery

In recent years, domestic and foreign research has begun on a variety of new varieties, of which the more prominent New lithium batteries have the following five.

1. Secondary batteries without metallic lithium

A secondary battery without metallic lithium uses a embedded lithium material as a negative electrode, also known as a lithium-ion negative electrode, and a positive electrode combined with an embedded lithium ion battery. In charge and discharge, lithium ions are reversibly embedded and degenerated between positive and negative poles. Because there is no metal lithium, the battery's cycling performance and safety performance have been improved.

2. Digitized lithium ion batteries

Digital lithium-ion batteries have high voltage, high specific energy, long cycle life, short charging time, rich raw materials, and safe use.

3. Polymer lithium batteries

Polymer Lithium (Li-polymer) batteries, using polymer materials as positive poles, lithium metals as negative poles, can be made into higher energy and higher density. In terms of structure, it is thin and thin, with a thickness of about 2 to 4 mm and a minimum thickness of 0.5 mm. It can be arbitrarily formed to make any shape and capacity. Its weight, energy, and density are higher than those of the current lithium electronic battery. 50 <UNK> or more, In terms of trust properties, because electrolytes also use polymer materials, there will be no safety concerns such as leaks and combustion explosions.
