AEROSIL® Fumed Silica for Batteries
AEROSIL ®气相法白炭黑的电池
AEROSIL® fumed silica is a highly dispersed silicon dioxide. Hydrolysis of chlorosilanes in an oxygen-hydrogen flame, produces a fine, amorphous white powder of very high purity. The extremely small primary particles result in a large specific surface area, ranging from 50 to 380 m2/g. Using the AEROSIL® process, other special oxides such as fumed aluminium oxide, AEROXIDE® Alu C, titanium dioxide, AEROXIDE® TiO2 P 25 or zirconium dioxide have been developed. The surface of AEROSIL® or AEROXIDE® particles can be chemically modified by reacting the silanol groups with various silanes and silazanes and this results in hydrophobic fumed silicas and hydrophobic metal oxides.
AEROSIL® fumed silica is mainly used for the manufacturing of battery gels and processing of lithium ion polymer batteries.

The use of AEROSIL® 200 and its compacted version, AEROSIL® 200 V, can improve the limitations of the widely used lead acid accumulators containing liquid electrolytes.
Conventional batteries, like the ones used in most automobiles, usually are not secure regarding acid containment and can only be used in upright positioning. Though this is currently acceptable for paved road conditions, it is not safe in other conditions. Highly corrosive battery acid can flow or leak out in off road conditions, at sea or in the air.
Adding AEROSIL® 200 / 200 V to the battery acid changes the acid to a gel like consistency, and prevents the leaking of the battery content. The accumulator continues to function, but the danger of leaking acid is reduced. Actually, the electrolyte thickened with AEROSIL® 200 / 200 V significantly increases the current capability and service life of the lead accumulators. These improved batteries are now being used in electric vehicles, forklifts, solar plants, radio s
使用AEROSIL ® 200和压缩版本， AEROSIL ® 200伏，可以改善的局限性，广泛使用的铅酸蓄电池含有液体电解质。
常规电池，像汽车中使用的大多数，通常不可靠就酸遏制和只能用于直立定位。虽然这是目前可以接受的条件，铺平道路，这不是安全的其他条件。高度腐蚀性电池酸可以流或泄漏在越野条件下，在海上或空中。
添加AEROSIL ® 200分之200五电池酸改变了酸凝胶样的一致性，并防止泄漏的电池内容。蓄电池继续发挥作用，但泄漏的危险酸降低。其实，电解质增厚与AEROSIL ® 200分之200 V大大增加了目前的能力和使用寿命蓄电池。这些改进的电池现在正在使用的电动车，叉车，太阳能厂，县广播电台

How to prepare Battery Gels?
如何准备电池凝胶？
There are two methods to incorporate AEROSIL® fumed silica into battery gels.
有两种方法将AEROSIL ®气相法白炭黑到电池凝胶。
§ ？ Direct incorporation
直接加入
Dispers AEROSIL® 200 / 200 V directly into the battery acid with 5-6 % concentration.
AEROSIL® 200 is the more effective rheology control additive, especially when low shear mixing equipment is available. The advantages of AEROSIL® 200 V are easier handling, less dust, reduced storage cost and easier processing due to decelerated gelling of the sulphuric acid. The use of AEROSIL® 200 V requires high shear mixing equipment.
Dispers AEROSIL ®200/200V直接到电池酸浓度5-6 ％。
AEROSIL ® 200是更为有效的流变控制添加剂，特别是在低剪切搅拌设备可用。的优势AEROSIL ® 200第五容易处理，减少灰尘，降低存储成本，更容易加工，由于减速凝胶的硫酸。使用AEROSIL ® 200 V需要高剪切搅拌设备。

2.锂离子电池
Lithium Ion Polymer Batteries
聚合物锂离子电池
Lithium polymer batteries are used for portable communication devices, also known as mobile communication products, including notebook computers, personal digital assistants (PDAs), handheld personal computers (HPCs) and cellular telephones.
This battery technology offers distinct advantages over other technologies. The batteries are thinner, lighter and generally achieve longer operating times than many other rechargeable batteries currently in the market. Unlike competing liquid lithium ion batteries that often require a metal casing to hold liquid electrolyte, lithium polymer batteries are manufactured with a foil casing, which makes them less bulky and less costly to produce.
AEROSIL® fumed silica is applied in lithium ion polymer batteries for the following effects:
？ absorption of plasticizer / electrolyte
？ reinforcing - good mechanical properties of the polymer
