Polymer lithium battery

Polymer lithium battery
According to lithium-ion batteries used in different electrolyte Laptop Battery materials, lithium-ion batteries can be divided into liquid lithium-ion battery (lithium ion battery, referred to as LIB) and polymer lithium-ion battery (polymer lithium ion battery, referred to as LIP) two broad categories. Polymer lithium-ion batteries are being used in lithium-ion anode materials and liquid are the same, the battery works are basically the same. Their main difference lies in the different electrolytes, lithium-ion batteries using a liquid electrolyte, while the polymer lithium-ion battery Zeyi solid polymer electrolyte to replace, such polymers can be a "dry state" can also be a "rubber state ", and now most of the use of polymer gel electrolyte. Polymer lithium-ion battery can be divided into three categories:

(1) solid polymer electrolyte lithium-ion battery. Electrolyte for the polymer with a mixture of salt, this battery at room temperature ionic conductivity is low IBM 40Y6797 Battery, suitable for high temperature use.

(2) gel polymer electrolyte lithium-ion battery. Namely, solid polymer electrolyte by adding plasticizers and other additives to enhance ionic conductivity, so that the battery can be used at room temperature.

(3) polymer lithium-ion battery cathode material. Using conductive polymer as a cathode material, the specific energy of existing lithium-ion batteries 3 times, is the latest generation of lithium-ion batteries. As with the solid electrolyte instead of liquid electrolyte, as compared with the liquid lithium-ion batteries, polymer lithium-ion battery technology with available thin, arbitrary area of arbitrary shape, and so on with the advantages, it does not produce leakage and combustion safety explosion the problem, so you can use plastic composite thin-film manufacturing battery casing, which can increase the ratio of the entire battery capacity; polymer lithium-ion polymer batteries IBM ThinkPad T60 Battery can also be used as cathode material, its quality will be compared with the energy of the liquid than the current lithium-ion batteries increased by 50% or more. In addition, the polymer lithium-ion battery voltage, charge and discharge cycle life than lithium-ion batteries and so on increased. Based on these advantages, polymer lithium-ion battery known as the next generation of lithium-ion battery.

Polymer lithium-ion Development Trend

Polymer lithium-ion battery in the global commercialization of technology is mature and has more than two years, although sales in the fast-growth, but its market share is still below 10%, with the liquid lithium 90% of the market share can not be compared with much lower in people's expectations. For various reasons, the current market price of polymers generally higher than that of liquid lithium, but because of competition from mobile electric model is quietly changing, especially in polymer batteries for mobile appliances designed to bring the value of innovation (such as 4mm thickness of less than superior performance, large size batteries), polymer batteries are being more and more mobile phones, mobile DVD, etc. recognized by designers, manufacturers and therefore polymer or confidence, convinced that the IBM ThinkPad R60 Battery era of polymer will surely come. Can be read from the phone's polymer lithium-ion battery development trends. At present mobile phone has the following trends:

(1) the phone itself to miniaturization and thin in the direction of development in order to facilitate the consumers to carry;

(2) mobile phone designed for personalization, expressed in the original design concept is no longer a square-shaped shape, irregular shape, curve, arc design modeling into the mainstream mobile phone design aesthetics;

(3) The use of color, cell phone features continue to increase. In order to make mobile phones smaller, the battery decreases, thinning is the most effective way. 4mm below the thickness of the battery to become the main trend of slim mobile phone configuration, from the price, this is the IBM ThinkPad A21M Battery polymer's strong suit. Irregular shape, curve, arc design of the shape of the battery cell phone to the left of the effective space into irregular shapes. Rectangular liquid is not an effective use of space, capacity, low, stacked polymer that can be the most effective use of irregular space, so that the capacity to enlarge. TCL has recently introduced deposit can arc-type batteries, trapezoidal battery, battery pack enables the handset to use the appropriate size of the liquid than the battery capacity increase of 50% or more. More and more phone features, resulting in more and more power consumption. Require a corresponding increase in battery capacity. Without increasing the thickness of the battery case, the polymer battery is a clear advantage. Similarly, laptop computers, Bluetooth headsets, PHS mobile phone, mobile DVD and other appliances are in the mobile, portable and direction, are coupled with a liquid crystal display, and features are on the rise, LCD screens continue to grow. All these have polymer lithium-ion battery provides unlimited business IBM ThinkPad A20M Battery opportunities.
