Pure Lithium and E3 Lithium Report Results From Phase 1 of the Lithium Metal Battery Joint Development Agreement
Several variations of E3's lithium chloride concentrate were used to make lithium metal anodes at Pure Lithium's Boston facility. The lithium from the E3 concentrated lithium chloride was electrodeposited as pure lithium metal onto a copper substrate, creating a complete, battery ready anode. These anodes were then assembled by Pure Lithium into batteries, and their electrochemical performance was evaluated in full cells. Notable results include:
Lithium Metal Purity: The various E3 brine streams all achieved a very high purity level, > 99.9% pure lithium metal as tested by ICP-OES analysis.
Cell Performance (Life Cycle): This tests for the number of charge and discharge cycles the battery achieves while retaining 80% of its capacity. All cells achieved over 500 cycles to date.
Charge and Discharge Rates: This tests for the duration of a charge and discharge. These tests were conducted at a 1C:1D ratio, one hour charge time and one hour discharge time.
The results of this study concluded that an easily producible version of E3's lithium concentrate provided the most cost-effective feedstock for use in Pure Lithium's batteries. It also demonstrated the robustness of Pure Lithium's process, showing no performance differences between batteries made using lithium chloride from E3's Leduc Brines, and those made from Pure Lithium's standard sources. The two companies continue to collaborate on the development and planning of an integrated process that can deliver the highest purity lithium metal anodes at the lowest possible cost.
"I am delighted to reinvent the lithium supply chain with E3 Lithium. We not only produced pure lithium metal anodes from unconventional sources of lithium using a newly invented technology but also validated their performance by cycling them in over 100 batteries. Rigorous electrochemical testing of battery materials is imperative, and to get such great results consistently, using a technology that was specifically developed to be cost effective, is truly exciting," said Emilie Bodoin, Founder, Chairman & CEO of Pure Lithium.
"These results confirm that E3's lithium concentrate can produce battery-ready lithium metal anodes using Pure Lithium's technology," said Chris Doornbos, President and CEO of E3 Lithium. "The Pure Lithium team has worked very hard in making these batteries and confirming the performance of our lithium. We are very encouraged by the results, and I am excited by the prospect of developing a local lithium battery supply chain in collaboration with Pure Lithium."

Shenandoah investigates financial mismanagement
Shenandoah borough officials have made inroads in their ongoing investigation of alleged financial mismanagement. Over the past few months, Shenandoah has taken measures to investigate claims of mismanagement presented by Borough Manager Mike Cadau, who was hired in January and found what he says are financial improprieties and misappropriation in the way previous borough administrators did business. On Monday, Cadau announced that officials from the Pennsylvania Auditor General's office will visit borough hall in September to conduct a comprehensive audit of the borough's Liquid Fuels account. Cadau has previously shared that he believes Shenandoah misappropriated funds from that account for projects not typically associated with it. The Department of the Auditor General, Cadau said, 'has been following what's been happening (from media reports), and they want to come in and they want to take a look at our Liquid Fuel accounts.' Also, Cadau said that he will join council president Joseph R. Boris and the borough's forensic auditor, Joseph Yanushefsky, at a meeting with the Internal Revenue Service in Wilkes-Barre on Aug. 25. Cadau said they were summoned by the IRS to go over an ongoing forensic audit led by Yanushefsky, whom the borough appointed this spring. At the meeting, they are expected to examine issues such as 941 forms, 1099 forms and pensions that the borough has provided over the years, Cadau said. Shortly after he was hired in January, Cadau described the borough as being in a 'very difficult' situation due to funding mishaps over the past two years. In May, the borough council appointed attorney Maria Casey as special counsel to help investigate the alleged mismanagement. At the July meeting, Cadau told council members that the Pennsylvania Office of Attorney General also will lead a criminal investigation into the matter. Other business Council members discussed an ongoing effort to repave several streets in the borough. After the successful curb-to-curb paving job done on five streets last year, the borough plans to pave five more by the end of November, Boris said. Boris said the borough will first repave North Jardin and Market streets, which will cost nearly $100,000 combined. Community Development Block Grant funds of $70,000 will be used to pay for those projects, with the remainder coming from interest received through the sale of the Municipal Authority of the Borough of Shenandoah, Boris said Tuesday. M&J Excavation Inc. of Bloomsburg has been tapped as the contractor for the two streets. The contract will be tentatively awarded at the Aug. 27 county commissioners meeting, Boris said. Also on Monday, Boris announced that attorney Shane Hobbs has resigned as the borough's solicitor. He read Hobbs' resignation letter, in which Hobbs stated that recent challenges — notably, his accepting a part-time job as a Schuylkill County Public Defender — resulted in his decision to leave. 'It was a pleasure working with you all,' wrote Hobbs, who served as solicitor since January 2024. Following Hobbs' decision, Boris said, council members interviewed a candidate, James E. Crossen III, of the Pottsville law firm Williamson, Friedberg & Jones. Council members appointed him as the new solicitor Monday. Council members also approved the hire of a new full-time secretary, Nazareth Perez. Solve the daily Crossword

Website helps families see school smartphone policies
Gov. Kathy Hochul announced Thursday, Aug. 14 the launch of a website — — that enables New York parents and students to look up their school's plan for implementing bell-to-bell smartphone restrictions this fall. According to a news release from Hochul's office, the website allows New Yorkers to search by district or school name among more than 1,050 public school districts, charter schools and BOCES that have already published their policy for the coming school year — representing about 96% of the about 1,090 total districts and schools covered by the statewide requirement. School administrators across the state are implementing the plans as part of a new law to require bell-to-bell smartphone restrictions in K-12 schools statewide. 'Our kids succeed when they're learning and growing, not clicking and scrolling — and that's why schools across New York will be ready to implement bell-to-bell smartphone restrictions this fall,' Hochul said. 'As we look ahead to the start of the school year, communication is key — and our new online resource is making it easier for parents and students to review their school's plan.' The remaining districts and schools yet to finalize their policies are expected to do so in the coming days at upcoming school board meetings scheduled for August. The state's online resource will continue to be updated when any additional policies are published and submitted, the release stated. The law enacted this year requires bell-to-bell smartphone restrictions in K-12 school districts statewide, starting this fall for the 2025-26 school year. New York's statewide standard includes: • Prohibiting unsanctioned use of smartphones and other internet-enabled personal devices on school grounds in K-12 schools for the entire school day, including classroom time and other settings such as lunch and study hall periods; • Allowing schools to develop their own plans for storing smartphones during the day — giving administrators and teachers the flexibility to do what works best for their buildings and students; • Securing $13.5 million in funding to be made available for schools that need assistance in purchasing storage solutions; • Requiring schools to give parents a way to contact their kids during the day when necessary; • Requiring teachers, parents and students to be consulted in developing the local policy; • Preventing inequitable discipline The policy allows authorized access to simple cellphones without internet capability, as well as internet-enabled devices officially provided by schools for classroom instruction, such as laptops or tablets used as part of lesson plans. Additionally, the policy includes several exemptions to smartphone restrictions, including for students who require access to an internet-enabled device to manage a medical condition, where required by a student's Individualized Education Program, for academic purposes or for other legitimate purposes, such as translation, family caregiving and emergencies, according to the release.

HelloFresh To Settle Consumer Protection Lawsuit With $7.5 Million Deal
HelloFresh To Settle Consumer Protection Lawsuit With $7.5 Million Deal originally appeared on L.A. Mag. HelloFresh, the world's largest meal kit delivery service, has been ordered to pay a $7.5 million settlement in a lawsuit co-led by the Los Angeles County District Attorney's Consumer Protection Division and the Santa Clara County District Attorney's Office. Allegedly, the company misled its customers, failing to adequately give notice to subscribers of continuing charges to their accounts. In a news release published by the Los Angeles County District Attorney's Office, the civil complaint detailed a list of alleged offenses, including negligence to 'Clearly and conspicuously disclose its subscription terms before collecting payment,' as well as failure to 'Offer an easy-to-use mechanism for cancellation.' Included in the release was a statement given by District Attorney Nathan J. Hochman, declaring, 'We will aggressively pursue enforcement when businesses take advantage of consumers by failing to clearly disclose subscription terms, obtain proper consent, or provide a fair way to cancel. Consumers have a right to know what they're signing up for, and they deserve better. Digital deception is still deception under the law.' The law in question refers to the California Automatic Renewal Law, which requires businesses to receive consumers' consent to automatic renewal and repeated service offers. District Attorney Hochman went on to thank the Consumer Protection Division and members of the California Automatic Renewal Task Force (CART), as well as applauding Deputy District Attorney Duke Chau: 'He and his team worked tirelessly with the Santa Clara County District Attorney's Office to secure a result that holds a major corporation accountable and delivers restitution to consumers. Their commitment to fairness and justice is what makes this outcome possible.'Filed in the Santa Clara County Superior Court, Judge Daniel T. Nishigaya ruled on Monday that HelloFresh was required to pay $6.38 million in civil penalties, $120,000 in investigative costs, and $1 million in restitution for impacted did not admit liability in the settlement, denying any wrongdoing and maintaining their commitment to customer transparency, underscoring their cooperation in the investigation and their compliance in settling amicably.
