Examples of embodiments are an ad hoc separator and the method of making it.
2. Description of the Related Art
With the growing capacity of secondary batteries, their applications areas are also expanding to high-capacity devices like power sources for electric vehicles and electric power storage systems. These types of applications can cause safety issues because of the production and use of these batteries.
A polyethylene separator can be used as a separator to secondary batteries. The polyethylene separator typically has good electrochemical stability and mechanical strength, but it may not have enough electrolyte wettability or satisfactory thermal stability, both of which can hinder the installation of high-capacity, high-output secondary batteries. To combat these shortcomings, coating ceramic particles or binder polymers on a surface of the separator made of polyethylene can be utilized. However, this process could be a disadvantage due to the melting point being low of the polyethylene itself.Click here to view the patent on USPTO website.

How to Search for Patents
- Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
- Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
- European Patent Office (EPO) provides esp@cenet to access a network of Europe’s patent databases with access to machine translation of European patents.
- Japan Patent Office (JPO) – with access to machine translations of Japanese patents.
- World Intellectual Property Organization (WIPO) offers PATENTSCOPE with a full-text search of published international patent applications and machine translations for some documents, as well as a list of international patent databases.
- Korean Intellectual Property Rights Information Service (KIPRIS)
- State Intellectual Property Office (SIPO) with machine translation of Chinese patents.
- Other International Intellectual Property Offices with online patent databases include Australia, Canada, Denmark, Finland, France, Germany, Great Britain, India, Israel, Netherlands, Norway, Sweden, Switzerland, and Taiwan.
- Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.
To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
