Green battery refers to a class of high-performance, non-polluting batteries that have been put into use or are being developed and developed in recent years. Metal hydride nickel batteries, lithium ion batteries, and mercury-free zinc-manganese primary and rechargeable batteries that are currently in large use, as well as lithium or lithium-ion plastic batteries and fuel cells that are being developed and developed, belong to this category. a category.
Lithium plastic battery (LIP) is a new type of battery with lithium metal as the negative electrode and conductive polymer as the electrolyte. Its specific energy has reached 170Wh/kg and 350Wh/L. Lithium-ion plastic batteries store the organic electrolyte in the current lithium-ion battery in a polymer film, or use a conductive polymer as an electrolyte, so that there is no free electrolyte in the battery.
The battery can be hot-pressed with an aluminum-plastic composite film, which is light in weight, arbitrarily changeable in shape, and safer. A fuel cell (FC) is a device that uses a fuel (such as hydrogen or fuel) and an oxidant (such as pure oxygen or oxygen in the air) to directly and continuously generate electricity. This power generation is avoided by avoiding the limitation of the Kano loop. The device is not only efficient (electrochemical reaction conversion efficiency can be as high as 40% or more), but also emits non-polluting gas, so it is an efficient and clean power generation method in the future.
Many companies at home and abroad are working hard to develop PEM fuel cells suitable for mobile phones and notebook computers. Once put into use, their economic benefits are extremely high. Sealed lead-acid batteries are one type of lead-acid batteries.
The following new green battery technologies and related industries are developing particularly rapidly:
1. Hydrogen storage material and metal hydride nickel battery - Ni-MH Rechageable Battery
2. Lithium ion embedded material and liquid electrolyte lithium ion battery
3. Polymer electrolyte lithium battery or lithium ion battery
4. In addition to the above, in view of the rapid growth of China's communications industry, China's battery industry is promoting environmentally friendly mercury-free alkaline zinc-manganese pools and rechargeable batteries and sealed lead acid at a very high speed. Battery technology development and expansion of the application market.
