This report takes a look into the patenting activity around thin film batteries uncovering the inventors, the companies and key technologies. Thin film batteries consist of a substrate, electrolyte, current collector, anode, cathode, and a charge separator.
The basic difference between thick film and thin film is the method of deposition of the metallization. In thick film, specially formulated pastes are applied and fired onto a substrate. The pastes are usually applied with a silk screen method and the substrate is of 96% alumina ceramic. Thin film technology is used wherever precision resistors are needed.
They can be used in various applications such as semiconductor industry, electronic industry, medical devices, aviation, and energy harvesting. This report focuses on how Patent data can help uncover the trends, gaps and opportunities that exist around this area. You will find the information on the research activity, existing & emerging trends in the different technological advancements in thin film batteries.

Thin Film Batteries
Introduction
Thin film batteries are similar to lithium-ion batteries, but they are composed of thin materials, some only nanometers or micrometers thick, which allow the finished battery to be just millimeters thick. These have been developed and advanced for the most part of the last ten years. These can be easily fabricated. They are flexible and non-breakable. Cells or batteries made from thin films can double up as building materials. This report takes a look into the patenting activity around thin film batteries uncovering the key companies, inventors, and different sub categories.

Introduction These batteries consist of a substrate, electrolyte, current collector, anode, cathode, and a charge separator. There has been much research into the determination of the most effective components for this type of battery. It has been shown recently that even ordinary printer paper can be used as a charge separator and a substrate. These thin film batteries are an improvement on the common secondary, or rechargeable, lithium ion batteries in many ways. These batteries exhibit the same voltage and current as their bulky counterparts, but their thinner dimensions allow for greater applications such as making thinner electronic devices, like cell phones and laptops and even implantable medical devices and reducing the weight of common devices that are run on battery power because of the batteries’ high energy density. These batteries can be formed into any shape and they can be stacked, to be used in parallel, thus even further reducing the space needed for a battery. The term “thin film” is derived from the fact that the deposited films are of the order of a few micrometers in thickness compared with the 10 to 50 micrometers for thick film. Often, thin film conductors are plated to improve conductivity. Thin film has the advantages of tighter absolute and ratio tolerances and more environmentally stable components with lower noise and tighter TCR than thick film. Thin-film printing technology is being used to apply solid-state lithium polymers to a variety of substrates to create unique batteries for specialized applications. Thin-film batteries can be deposited directly onto chips or chip packages in any shape or size
The basic distinction between thick film and thin film is the method of deposition of the metallization. In thick film, specially formulated pastes are applied and fired onto a substrate. The pastes are usually applied with a silk screen method and the substrate is of 96% alumina ceramic. Thin film technology is used wherever precision resistors are needed.

Once the patents were populated in Patent iNSIGHT Pro, the assignee clean- up tools were used to normalize the names. Different cleanup tools were leveraged: • To locate assignees for unassigned records • To clean up records having multiple assignees • To locate the correct assignee names for US records using the US assignments database • To merge assignees that resulted from a merger or acquisition or name change.
The dashboard tool within Patent iNSIGHT Pro was used to find the top 20 assignees within the given patent set.

Summary
Thin film batteries reduce the amount of light absorbing material required in creating solar cells.
This can lead to reduced costs in case of silicon thin films and also tend to reduce energy
conversion efficiency. The lifetime of thin-film batteries is potentially very long. Thin-film
batteries combined with energy harvesting can last decades. Longer lasting batteries mean
fewer surgeries, less risk of complications, and better patient outcomes.
These can replace heavy batteries currently being used in cells. And also create biodegradable natural cells or batteries This report talks about the existing & emerging trends in the different technological advancements in thin film battery domain.
