Energy storage and energy conversion devices are both used to fill the need for portable as well as renewable power. The evolving needs require the improvement in capability to provide pulse-power, long run-time and cycle life. New materials and advancements of engineering play a key role in meeting the market demand.
Li-ion batteries are today’s leading technology in this space. Cyclic voltammetry is used in the development of the material and identification of its potential window (charge cut-off voltage and discharge cut-off voltage), and is also the primary technique in identification of new electrolytes. The BNC connections of both the Solartron Analytical EnergyLab and Princeton Applied Research potentiostats provide an interface common for the glovebox feedthroughs often needed for this type of research.
As the goal of a rechargeable battery is to provide high cycle-life, high efficiency, and high energy density, prospective new materials are combined into a complete cell and tested in a charge – discharge experiment to determine the capacity vs cycle number, cycle-life and Coulombic efficiency. Battery holders for PARSTAT and VersaSTAT potentiostats allow for direct connection of common battery formats to the instrument. Direct connection through a battery holder avoids the added stray capacitance and inductance to impedance measurements, and creates a cleaner signal and a cleaner lab.
The use of auxiliary voltage measurements allows monitoring of both the anode and cathode of a battery. Standard potentiostat design concentrates on the signal and response at the Working Electrode, and the Counter Electrode reactions are not characterized. Other applications use an inert Counter Electrode, but in battery technology this is an active electrode. Being able to characterize this terminal allows users to identify failure mechanisms and properly focus research initiatives. This is available on the PARSTAT 3000A and EnergyLab products for single cell evaluation and PARSTAT MC for multichannel, simultaneous tests for improved throughput.
The typically flat-voltage profile, seen as a key advantage of Li-technology, drives the need for advanced techniques to determine State of Charge. Electrochemical Impedance Spectroscopy (EIS) is the emerging method for making these determinations in-situ. EIS is also used to determine how the battery is functioning with respect to its anticipated lifetime (State of Health). The full range of products from Princeton Applied Research and Solartron Analytical provide these measurement capabilities either as standard or as options. EIS also provides a mechanism via equivalent circuit analysis or simple visual reference to identify the Equivalent Series Resistance (ESR) of a battery. This is a key figure of merit as it represents a loss of the system. The EnergyLab EIS methods, including its innovative FRA-technology and oversampling, allows for characterization of devices of micro-ohm impedance.
For extreme applications that require greater than 5 V or 2 A of current, batteries can be configured in stacks. Since stacks are purposefully designed for operation at high voltages (up to 100 V) or high currents (up to 100 A), external boosters are required. External boosters are available in a wide range of measurement capacities, bandwidth and accuracy to meet a given testing profile. The PMC-2000A and PARSTAT3000A provide the voltage range to test a stack of batteries as well as the standard, additional electrometer to measure the characteristics (including impedance) of a single battery within the stack. The EnergyLab provides multiple electrometers to study even more cells within the stack.
Whatever your requirements in state-of-the-art energy storage and energy conversion applications, AMETEK’s Princeton Applied Research and Solartron Analytical advanced instrumentation provides the tools for market leading impedance analysis, with the widest voltage and current ranges available for anode/cathode and stack testing.

COVID-19 update –
The Team at Elliot Scientific are continuing to support our partners and customers through this challenging time. For the safety of staff we are still running remote working for many members of staff- but have a physical presence at the office to maintain those aspects of the business which require this presence. Deliveries and shipping continue as before and in most cases we can continue to provide continuity of supply at the same pre-CV19 level.
We will continue to monitor the situation and update any changes on our website.
Email and Phone enquiries are answered by our remote working team members and a range of remote services (web video/ support) to support our customers continue to be available as before.
If there is any way we can assist or support you during these challenging times please contact us and we will look at how best to assist you.
The Elliot Scientific Management Team
Just an update to let all of our customers and clients know that the team here at Elliot Scientific are all well and still supporting business. The office is running a skeleton staff to provide protection to our employees but enable shipments and deliveries to be processed. The majority of the team are working remotely. During this remote activity- communication is best achieved through email to :
- email@example.com or alternatively
- The main telephone line is being answered and on occasion will divert to our mobile App users to answer
- Direct dial extensions should automatically direct to the users company mobile.
- Direct emails to individual staff members are being picked up by them from their home offices.
We hope that the measures that we have put in place enable us to provide support and continuity to the supply chain for all of our customers.
the Elliot Scientific Management Team
The global spread and impact of the novel coronavirus outbreak is affecting all of us but the Elliot Scientific Team are continuing to support customers and researchers to maintain the business supply chain during this challenging time.
We have taken steps to mitigate the transmission of the virus within the team here in the UK and to protect our employees – thus many have adopted a more flexible and safer working practice (staff are working from home, reduced attendance or are out of the office during periods of self isolation/ distancing measures).
Our remote IT systems will enable us to accept orders, respond to customers enquiries and whilst we will endeavour to fulfill shipments as normal, some deliveries may occasionally be affected – in which case we will inform you of any impact on your particular order.
We will continue to monitor the situation and inform our customers or any changes or amendments.
The Elliot Scientific Management Team
Elliot Scientific Ltd will be monitoring the status of the current outbreak and will be restricting oversea’s visits and non-essential UK customer visits for the coming weeks. Employees will still be available via the phone , mobile or the office line, Email, or through video web calls to maintain business as usual whilst reducing the possible contact and potential spread of the COVID-19 virus. As with many companies, we will be implementing flexible approaches to working- such as some staff working from home- but be assured we will be able to support and respond to your requirements. – Best Regards- The Elliot Scientific management team.
