Batteries.

An international team of researchers has developed a proof of concept technique for precisely tracking the movement of lithium ions moving through a polymer electrolyte within batteries.

The researchers used X-rays to determine the velocity and concentration of ions within a battery, then compared those results to theoretical models to determine the ion transport number, a fraction of electric current carried by ions in an electrolyte.

UK-based recycling development firm Ever Resource has been awarded £237,425 ($315,500) grant funding to produce lead oxides for enhanced lead-acid technologies from old batteries.

The cash from Innovate UK's 'Sustainable Innovation Fund (round 1)' framework will allow Ever Resource to begin testing its nanostructured lead oxides in commercial lead-acid batteries.

Russia state-operated nuclear energy firm Rosatom has incorporated Rosatom Energy Storage Solutions (RENERA) to develop and trade lithium-ion traction and stationary batteries.

RENERA, the new name of Cathode Materials, a 100% subsidiary of Russian nuclear fuel cycle firm TVEL (owned by Rosatom), will develop batteries for electric vehicles, and energy storage systems.

Battery materials firm Solvay and energy management firm Veolia are partnering on a circular-economy consortium to manage critical metals used in lithium-ion electric vehicle (EV) batteries.

Belgian firm Solvay and French company Veolia , through its subsidiary SARP Industries, are engaged in discussions about the battery value chain— from access and spent battery feedstock to dismantling, metal extraction and purification— with a car manufacturers and battery cell producers.

Exide Technologies in Europe has launched a free battery-testing app to make it easier for workshops to test and replace 12V lead-acid batteries.

The app works on any device with a web browser and is designed to work alongside the Exide EBT965P battery tester, which can test standard, GEL, AGM and EFB 12V batteries.

The next-generation device will allow mechanics to analyse battery test results and give customers battery replacement options within five minutes via SMS or email.

Workshops are alerted as soon as a customer authorises the replacement. Workshops can then present multiple battery options based on the fitment list coming from Exide. 

The system performs advanced analysis on the battery through Conductance Profiling™ technology covering cranking health, voltage, temperature, reserve health capacity and recommendations for further battery treatment such as recharge.

Each test produces a QR code, which the app can scan to import the test results. These test results can also be entered manually.

The app works in most European countries, is available in 13 languages and supports multiple currencies.

Workshops can register for free at ebtp.exide.com. 

This week Exide in Europe launched its grid-focused GNB Marathon FTX range of advanced AGM batteries for telecom and electric utility applications.

The battery uses a MICROCAT® Catalyst to reduce float current and minimise water loss by recombining the hydrogen and oxygen chemically back into water, further increasing the battery lifespan. The firm says this enables a service life of five years at 40°C to reduce the overall cost of ownership— a key consideration when pitting lead-acid against lithium-ion batteries in the above applications.
