Tesla and Panasonic’s recent announcement of the new 2170 format cell has sparked renewed interest for an easy-to-use cell holder intended for high energy density and high capacity cells.  Most industry available battery solutions cannot handle the high current delivered from the cylindrical format cells.  Arbin’s recently redesigned High Current Cylindrical Battery Holder provides a perfect solution for currents ranging from 5A up to 200A.  The battery holders are designed to provide an economic solution, allowing for quick setup and connection to Arbin’s battery test equipment or other testing assemblies.  We are now accepting pre-orders for the first round of deliveries by September 2017.

The new 2170 format battery cells are capable of holding more raw materials and providing consumers with longer battery life.  In addition to Tesla and Panasonic, Samsung and several other battery manufacturers are already beginning to move towards the new format and will soon begin production.  Arbin’s High Current Cylindrical Battery holder is perfectly designed to work with the 2170, or 21700, cell with the dimensions of 21 millimeters in diameter and 70 millimeters long.

Arbin’s High Current Battery Holder allows the user to quickly connect and disconnect the device under test, eliminating the down time associated with previous commonly used connection methods. This specialized holder accommodates testing applications with a maximum current ranging from 5A up to 200A, lengths ranging from 10 mm to 120 mm, and a diameter of 10mm to 35 mm.  The reengineered battery holder has adjustable contact probes, along with a single, spring lever mechanism to provide secure contact to the battery resulting in very low contact resistance and no damage to the device being tested. By having low contact resistance, the end user does not have to worry about the destructive high temperatures that usually develop in conjunction with high resistance to the current flow.

Please contact Arbin if you are interested in trying the new High Current Cylindrical Battery Holder.  We are now accepting pre-orders for the first round of deliveries by September 2017. Click here for more details on ordering. 

Arbin offers a complete collection of individual battery holders, trays, and racks for all types of cell:  [LEARN MORE]

Arbin's new Precision High Power Battery Tester, developed in conjunction with Ford Motor Company and Sandia National Labs, has received the Special Recognition: Green Tech, Merit Award from the R&D 100 Organization.   For more than 50 years, the R&D 100 Awards have served to recognize industry breakthroughs for new ideas and product developments.

By detecting minute signatures of battery degradation trends earlier, the Precision High Power Battery Tester provides valuable insights into the long-term future of a battery, allowing engineers to sort promising technology ready for new products from concepts that need additional refinement in the lab. Thus, this tester has the potential to dramatically accelerate the rate of battery technology development to help meet the growing worldwide demand for long-life automotive and stationary batteries – and, ultimately, usher in a new era of green technology.

One significant benefit of improved current and voltage testing precision is the ability to derive coulombic efficiency (CE) measurements on a large scale. CE testing is commonly performed in academia, but at a scale relevant for industrial battery performance the lower precision of existing testing equipment has precluded its use. CE is an aggregate metric, essentially how many electrons go into a battery versus how many are discharged. A high CE value denotes a battery with low loss, with a 1 (or 100%) denoting perfect utilization or efficiency. Low CE indicates losses due to side chemical reactions, heating of battery elements, changes in entropy, and other factors. The expected behavior of a battery’s CE over time is a power law decay towards 100%, as the initial CE losses of a lithium ion battery are greatest at the beginning of cycling (Figure 1). This expected behavior is seen in high precision testing but is obscured by imprecision in the case of a conventional tester. The Precision 25 was designed to measure current and voltage precisely enough to enable the CE equations to have meaning for industrially relevant life.

The Arbin High Power Precision 25 is the highest power high precision tester on the market at
200 Amps, an amperage relevant for electrified vehicle and grid storage applications. Arbin also
offers 50 Amp, 5 Amp, and 1 Amp models with better precision and better accuracy than known
competing technologies at these current levels. The High Power Precision 25’s analytical and research
applications include battery, capacitor, and half-cell testing; materials testing; quality control for
materials; and sampling of battery products for reliability.
