Scientists from Russia’s Skolkovo Institute of Science and Technology (Skoltech) and Moscow State University have developed the charge storage mechanisms of NiBTA, a recently discovered material that can enable advanced batteries to fast charging. Today, the development of fast-charging metal-ion batteries is crucial to solving the problem of range anxiety that has held back the mass adoption of electric vehicles. Since conventional graphite anodes are not suitable for rapid charging due to the dangerous formation of low-potential dendrites, Russian scientists explored the working principles of the recently proposed NiBTA, a one-dimensional coordination polymer based on Ni derivative of benzenetetramine (BTA), in batteries based on lithium, sodium and potassium. Among other techniques, both experimental and theoretical, scientists have used operand and ex-situ X-ray diffraction, operand Raman spectroscopy and ex-situ Near-Edge X-ray Absorption Spectroscopy (XANES), which allowed them to track structural changes inside batteries in detail. “We were the first to apply such a rigorous approach for this class of compounds. This study sheds light on the redox chemistry of coordination polymers, which can be useful for many applications,” says the study’s first author, Skoltech Professor Roman Kapaev. In partially sodium or potassium states, the material undergoes rapid bulk faradaic reactions, which should be beneficial for high-throughput capabilities. The different behavior in Li, Na and K based systems is explained by the distinct rearrangements of the crystal structure. At the molecular level, the charge-discharge mechanism is similar for all types of batteries. Their findings were published in chemical sciences.

Mercedes-Benz is investing billions of euros in its European assembly plants to prepare them for the production of all-electric vehicles by the end of the decade. The luxury automaker said its German factories in Sindelfingen, Bremen, Rastatt and the plant in Kecskemét, Hungary, will start producing the new electric models in the Top End Luxury, Core Luxury and Entry Luxury categories from the middle. of the decade. The Sindelfingen site is Top End Luxury’s lead plant and will produce models of the AMG.EA electric platform from 2025. The Bremen and Kecskemét plants will produce models of the MB.EA electronic platform – i.e. the Core Luxury models – and the Rastatt and Kecskemét plants will build the MMA repositioned model platform from 2024. As part of the implementation of the 2022 business plan -2026 of the company, Mercedes-Benz announces to invest more than 2 billion euros in its European production sites. “This milestone marks a new phase of introducing next-generation electric platforms into production, securing future jobs at European sites,” the company said. The production portfolio already includes six fully electric Mercedes-EQ models, rolling off the production line at six sites on three continents. Mercedes currently sources batteries for electric vehicles from a global network of partners with factories on three continents, but sees local battery production as “a key success factor”. In order to further deepen the vertical integration in manufacturing and development, the manufacture and assembly of parts for the electric drive systems of future models of the Mercedes-EQ brand will start at the end of 2024 at the Untertürkheim plant. Meanwhile, its Berlin plant will in future expand its production portfolio to include the manufacture and assembly of high-performance electric motors from acquired British specialist Yasa. In terms of sustainable development, the company aims to increase the production of renewable energy on its sites. Solar power plants with a capacity of more than 11 MWp are due to come on stream by the end of next year. By 2025, Mercedes-Benz plans to invest a triple-digit sum in the installation of photovoltaic systems, in addition to new power purchase agreements for wind turbines worth 1 billion euros. mid-decade here. By 2030, it is expected to meet more than 70% of the energy demand in production from renewable energy sources – 15% to be generated by on-site renewables.

LG announced its entry into the electric vehicle charging station business with the acquisition of South Korean charger maker AppleMango. Together with GS Energy and GS Neotek, an energy service company and related IT service provider, LG purchased the company to create “complete charging stations” and integrate the existing in-house developed charging management system. Founded in 2019, AppleMango has developed proprietary technologies and systems, including a slim and aesthetic fast charger. According to LG, the acquisition secures access to the necessary operational infrastructure by working closely with GS Energy and GS Neotek, both of which have considerable experience in operating electric vehicle charging stations and businesses. related. LG also plans to add digital signage technologies to create charging stations with a user-friendly interface and real-time control/management. The company explicitly mentioned its IP-rated outdoor digital display with a rugged, dustproof and waterproof casing. This year, LG will establish an electric vehicle charger production line at LG Digital Park in South Korea and aims to provide a customized charging solution for various environments, such as private residences, shopping malls, hotels and institutions. public in the near future. Additionally, LG expects the acquisition to create synergy with the company’s “continuing efforts in vehicle components, including the development and supply of EV batteries and adjacent products, such as energy storage system (ESS) and energy management solutions”. LG expanded the e-mobility portfolio with the recently launched electric vehicle charging solutions business, joining LG Vehicle Component Solutions (VS), ZKW Group and LG Magna e-Powertrain, which recently became a supplier principal of General Motors.

Electrifying America said on Tuesday it has raised $450 million in a deal that includes its first outside investor in a bid to accelerate its rollout of ultra-fast charging stations in the United States and Canada. The deal, which values ​​North America’s largest super-fast electric vehicle charging network at $2.45 billion, includes more than $100 million from German industrial company Siemens and additional capital from the group. VW on top of its initial $2 billion commitment through 2026. Electrify America said the investment highlights the long-term growth and viability of its plans to expand to 1,800 charging stations and more than 10,000 super-fast chargers in the United States and Canada by 2026.

In an update to his 2020 study, the Faraday Institution predicts there will be demand for 10 UK-based gigafactories by 2040, each producing 20 GWh per year of batteries. The study reveals that the United Kingdom is progressing but not fast enough compared to its European competitors. “Battery manufacturing plants in the UK could reach a combined capacity of 57 GWh by 2030, equivalent to around 5% of total European capacity in GWh, compared to 34% in Germany,” the update says. day. According to the study, by 2030 around 100 GWh of supply will be needed in the UK to meet the demand for batteries for passenger cars, commercial vehicles, heavy goods vehicles, buses, micromobility and online storage. network. This demand is equivalent to five giga-plants, each plant operating at a capacity of 20 GWh per year. By 2040, demand is expected to reach nearly 200 GWh, or the equivalent of 10 gigafactories. In addition, the overall automotive and EV battery ecosystem industry workforce could increase by 100,000 jobs, from 170,000 to 270,000 employees by 2040, versus the Faraday 2020 report which predicted a growth of 50,000 jobs from 176,000 to 220,000 employees by 2040. is well positioned to take a leadership position in next-generation batteries such as solid-state, lithium-sulfur and sodium-ion technologies. The UK is already home to world experts in battery research and well-established companies. We must act quickly to harness this competitive advantage by establishing large-scale domestic manufacturing in the UK while continuing to fund long-term battery research,” said Faraday CEO Pam Thomas.

Since July 1, the Australian Labor Government introduced new incentives for electric vehicles, including plug-in hybrids, fulfilling a promise made before the election. The so-called electric car discount comes in the form of exemptions from import duties and employee benefit taxes, depending on the country of origin. Cars from most of Europe, Japan and South Korea are expected to cost thousands of dollars less once the 5% import duty drops. Some popular models that benefit from the import duty waiver are the Nissan Leaf, Mercedes EQA, Hyundai Kona EV and Mini Cooper SE. For example, the Electric Vehicle Council estimates that a $50,000 model like the Nissan Leaf will cost over $2,000 less due to the removal of import duties. The so-called employee benefit tax will apply to company cars provided to employees for personal use, qualifying for a tax rate of 47% on the financial benefit of the arrangement. The Labor government has estimated that excluding electric vehicles from benefits tax could reduce the cost of electric vehicles by up to $9,000 for models costing around $50,000. Any exemptions will only apply to electric vehicles priced below $77,565 in 2020-21, the luxury car threshold for fuel-efficient vehicles in Australia.
