Pressurex® Pressure Indicating Sensor Film Minimizes Defects and Improves Quality in Battery Lamination
Pressurex® film is an economical, accurate and easy-to-use tool that reveals the distribution and magnitude of surface contact pressure in battery lamination and calendaring presses. Difficult to detect pressure variations across the surface of battery laminators and calendar presses can be easily detected and corrected through use of the sensor film.
When placed between lamination platens or calendar rolls, Pressurex® instantaneously and permanently changes color directly proportional to the actual pressure applied. Precise pressure magnitude is then easily determined by comparing the resultant color intensity to a standardized color correlation chart (conceptually similar to using Litmus paper). No training or instrumentation is required.
Pressurex® helps to ensure uniform alignment of mating rollers and lamination platens. If the contacting rollers and platens are not parallel, uneven compression could result in delamination during battery discharge or poor contact between the electrodes and their current collectors. Electrodes could also have uneven thicknesses reducing contact area, which is a major problem for cylindrical Li-ion and Li/MnO2 cells and prismatic cells. In addition, uneven contact in heat seal presses could cause leakages in pouch cells.
All four battery types that require a lamination stage can be manufactured and monitored with Pressurex®, including:
- Polaroid P-80, Zinc-Manganese Dioxide ((Zn/MnO2) Cells - The contents of the battery are laminated within a “coffee-bag” material using a bag heat sealer.
- Lithium-Manganese Dioxide (Li/MnO2) Pouch cells – Similar to the P-80 battery, these cells are laminated into bags. In addition, the current collector for the lithium is laminated to the inside of the bag through using a small pneumatic or hydraulic press with heated platens.
- Lithium-ion (Li-ion) Polymer Cells -- The positive and negative electrodes for these cells are cast from slurries containing the active ingredients, binders, and conductive media. They are then laminated to their expanded-metal current collectors and a separator layer is also cast. Then, the positive and negative electrodes are laminated to the separator using either heated double-roll laminators or parallel-platen presses.
- Metal-Air Cells -- Metal-air cells utilize an air electrode consisting of a carbon layer, nickel mesh, a second carbon layer, and Teflon film. These four layers are laminated together in a continuous web process using a laminating press.
During calendaring operations, positive and negative electrodes for Li-ion cells and the MnO2 electrode in Li/MnO2 cells are densified using calendering equipment. The electrodes are passed through heavy calender rollers in a continuous process.
Pressurex® is virtually indispensable for manufacturing process control and machine/component inspection. “Snapshot” imaging results of the film can be used as a control to compare processes and tools, making it ideal for Six Sigma and other closely monitored high performance manufacturing operations. The spatial resolution of the film is very fine (dense) revealing minute surface defects and other imperfections. Additional pressure analysis of the exposed film is available, if desired, through Sensor Products Inc.
Pressurex® measures pressures from 2 - 43,200 PSI (0.14 - 3,000 kg/cm2). The pressure-indicating film is very thin (4 mil or 8 mil thick) and can be hand or laser-cut to any size or dimension. It is flexible and conforms to curved surfaces and invasive intolerant environments.
The film is coated on a Mylar sheet and is physically similar to a standard sheet of paper. Pressurex® is available in eight pressure ranges.

Saelig Debuts Dongle for Economical USB to I2C Connection with No Software Driver Requirements
Saelig Company, Inc. (Saelig) (www.saelig.com) has announced the availability of model IOW24-DG, a USB to I2C Dongle offering a simple, easy to use, economical solution for connecting with I2C devices via USB port.
Connecting sensors, service interfaces, test and evaluation circuits and other applications can be easily accommodated with the IOW24-DG I2C dongle. The I2C master interface operates at 100 kHz and allows a throughput of up to 750 bytes/s. Handshaking via clock stretching is supported, as well as a programmable time-out function, to prevent the dongle from hanging up due to malfunctioning slave devices. A special mode to talk to Sensirion™ humidity sensors is also available. The IOW24-DG dongle is shipped as a set, consisting of the assembled and tested printed circuit board (PCB), a four-wire cable and a two-part snap-fit dongle case. The cable can be soldered to the dongle PCB, allowing flexible pin-outs to fit customer applications. 5V and 3.3V outputs are also available to power small external circuits, such as ambient sensors. To allow compatibility with 3.3 V slaves, internal pull-up resistors can be switched off under software control. The dongle PCB has solder pads for pull-up resistors and protection diodes to 3.3 V.
The mechanical dimensions of the IOW24-DG dongle are within limits for use with a USB standard plug. This prevents the dongle from blocking adjacent ports and allows multiple dongles to be used on a single computer or USB hub without losing ports. Since the dongle is based on a standard IO-Warrior24 chip from CodeMercenaries, the software and development tools for IO-Warrior are also useable for the dongle. This means that support for Linux, MacOS, and Windows, as well as for many development systems, is available. No specific drivers are required, since the dongle works with its own standard built-in system drivers.
The IOW24-DG dongle is available now from Saelig, with units starting at $39.00 USD (qty: 1). For detailed specifications, free technical assistance, or additional information, please contact Saelig (toll-free in the US) 1-888-7SAELIG, via email: info@saelig.com, or visit www.saelig.com.
