Do you know Laptop battery material types?

Laptop battery refers to the device that can convert other forms of chemical energy, light energy, atomic energy and so on into electric energy, and the converted electric energy can be applied to a laptop. It has a one-time battery (commonly known as dry cell batteries) and secondary batteries (that can be rechargeable batteries), as technology advances and development, the battery has experienced nickel-cadmium batteries to nickel metal hydride batteries, lithium batteries (including lithium metal batteries and lithium polymerization Batteries) and developing fuel cells. Every technological innovation not only makes the battery in the capacity, weight, ease of use have a major breakthrough, but also become more and more environmentally friendly.

Notebook battery types and characteristics:

Nickel-cadmium battery (Ni-Cd)

Nickel-cadmium batteries have been used in many products before, but because of its severe memory effect and the use of nickel (Ni) to pollute the environment, they were soon abandoned by notebooks and replaced by better NiMH batteries.

Ni-MH battery (Ni-MH)

It is basically the same as the principle of nickel-cadmium battery structure, only the cathode replaced by better performance, more environmentally friendly non-toxic nickel-metal hydride materials. Although only a small change, but it has brought great performance improvements. Another advantage of this is that the memory effect is not noticeable, so that we no longer have to worry about the nasty memory effect to make it easier to use. Although the performance of nickel-metal hydride batteries is very good. But as technology advances, it is replaced by lighter, more energy-dense lithium batteries.

lithium battery

Many people think that when it comes to lithium batteries we refer to our now commonly used lithium polymer batteries, in fact, lithium-ion batteries include lithium-ion batteries (Li-MO2) and lithium-polymer batteries (Li-ion) two. Because the Li-MO2 battery died in a fire bombing when it entered the market in 1989, it quickly disappeared from sight and replaced it with safer lithium-polymer batteries. It is light weight, in the case of the same capacity it weighs only about 1/2 of nickel-metal hydride batteries, so it is quickly used by most laptops, is now the main component of the laptop battery

Fuel Cell

Is a fuel and oxidant chemical energy through electrochemical reactions directly into electrical power generating device. Fuel cells can theoretically run at near 100% thermal efficiency with high economics. The current actual operation of various fuel cells, due to various technical constraints, and then consider the entire device system energy consumption, the total conversion efficiency of more than 45% to 60% range, such as the consideration of heat recovery up to 80%.
In addition, fuel cell devices contain little or no moving parts, work reliably, require less maintenance, and are quieter than conventional gensets. In addition the electrochemical reaction clean, complete, rarely produce harmful substances. All this makes the fuel cell is regarded as a very promising energy power plant.
Fuel cell is an electrochemical power generation device, isothermal electrochemical method directly to chemical energy into electricity without having to go through the heat engine process, without Carnot cycle limit, and thus energy conversion efficiency, and no noise, no pollution , Is becoming the ideal way to use energy. At the same time, with the continuous maturity of fuel cell technology, the commercial application of fuel cells has broad prospects for development.
