What is green batteries ?

Green means the battery has been put into use in recent years or are in the process to develop a class of high-performance, non-polluting batteries. Has been substantial use nickel metal hydride batteries, lithium-ion batteries and is promoting the use of mercury-free alkaline zinc manganese dioxide primary batteries and rechargeable batteries, as well as being developed, the development of plastic lithium or lithium-ion batteries and fuel cells all belong to this 1 areas. In addition, the current has been widely applied and the use of solar energy for photovoltaic conversion of solar cells (also known as photovoltaic power generation), could also be included in this category.

Nickel-metal hydride ibm laptop battery (Ni-MH) batteries and nickel cadmium (Ni-Cd) have the same operating voltage (1.2V), but because of the use of rare earth alloy TiNi alloy or hydrogen storage materials as negative electrode active material, replacing the carcinogenic substances cadmium, not only makes this new type of battery as a green battery, but also improve the battery's specific energy of nearly 40 percent, reaching 60-80Wh/kg and 210-240Wh / L. Such batteries are the early 90s and gradually realize the industrialization, and the first to use in mobile phone batteries. Although its dominant position on the mobile phone gradually being replaced by lithium-ion batteries, but in Europe and the United States mobile phone applications, its market share is still 50%.

Lithium-ion pavilion ze2000 battery (Li-ion) by the lithium ion can embed and off for the negative electrode carbon inlay, reversible lithium metal oxides for the cathode (LiCoO2, LiNiO2 or LiMn2O4) and organic electrolyte composition, its working voltage is 3.6V and, therefore, a lithium-ion battery is equivalent to three nickel-cadmium or nickel metal hydride batteries. Thus the specific energy of this battery is more than 100Wh/kg and 280Wh / L, also much higher than the nickel metal hydride battery energy. In light of the above advantages, since a short period of 1993-2000 years, its production and use of a very high pace.

Alkaline Zn-Mn dry presario m2000 battery (alkaline) than with the size of an ordinary dry-cell batteries have higher capacity, and have large current discharge capacity. In recent years, has applied for mercury-free zinc powder, so to make this battery as a green batteries, and become the mainstream of the original battery in the Product, the current alkaline zinc manganese dioxide batteries are still BP machine to use the most power. At the same time, countries around the world are also concerned about such a rechargeable battery, and the United States, Inc. has introduced a rechargeable alkaline manganese batteries, slow growth in product applications. This battery to maintain the original battery discharge characteristics, and can recharge using the scores to hundreds of times (deep charge-discharge cycle life of about 25 times).

Plastic lithium presario v2000 battery (LIP) are lithium for the anode, conductive polymer electrolyte for a new type of battery, its energy has reached 170Wh/kg and 350Wh / L. Type of plastic lithium-ion battery lithium-ion batteries currently in the organic electrolyte stored in a polymer film, or the use of conductive polymers for the electrolyte, the battery is no free electrolyte. This battery can be aluminum plastic composite membrane pressing implementation package has light weight, the shape can be changed, better security features. Fuel cell (FC) is a use of fuels (such as hydrogen or containing fuel) and oxidizer (such as pure oxygen or oxygen in the air) directly for power generation devices, because of the Carnot cycle to avoid the restrictions, this type of electricity generation device not only efficient (conversion efficiency of electrochemical reaction can be as high as 40% or more), and non-polluting gas emissions, so are the next generation of efficient and clean way.

Many domestic and foreign companies are committed to the development of suitable mobile phone, notebook computer PEM pavilion dv2000 battery , hp hstnn-lb31, once the input application, and its great economic benefits.

Sealed lead-acid hp f4486b ,hp cgr-b1870ae is a lead-acid batteries. The following new green pavilion zd7000 battery , pp2182d battery technology and the development of related industries was especially fast.

1. Hydrogen storage material and nickel metal hydride hp 338794-001 , hp pp2182l battery - nickel metal hydride battery (Ni-MH Rechargeable Battery)

2. Li-ion embedded materials and liquid electrolyte lithium-ion batteries

3. Polymer electrolyte lithium hp pavilion dv8000 battery , hp hstnn-db20 or lithium-ion batteries
4. Zinc-air batteries and PEM fuel cell In addition to the above, the communication industry in China's high-speed growth, China's pavilion dv9000 battery , hp ev087aa industry is a very high speed to promote environment-friendly mercury-free alkaline zinc manganese dioxide primary pool and rechargeable batteries and sealed lead-acid battery technology to develop and expand the application market.
