During the last years, several efforts have been made to calculate the Carbon Footprint of different battery technologies, mainly lithium ion. This value depends on several factors such as: the type of technology, its application, the manufacturing process, the size, the energy source used during production, the country where it is produced, the stages of the life cycle that have been included, among others. Analyzing the most relevant studies of recent years, it is established that CO2 emissions per kWh of lithium ion batteries are in a range between 70 and 170; while for solid state they are between 75 and 120; and for sodium batteries between 80 and 110. In the case of lithium ion batteries, it is the cathode that, as a general rule, contributes between 27 and 39% of the impact.

Are you curious about the chemistry powering the next generation of batteries? I covered the six major types of lithium-ion batteries here: https://lnkd.in/dxBrcfuc Let’s delve into the five cathode chemistries for sodium-ion batteries, each offering unique advantages. [1] Layered Transition Metal Oxides: They are similar to the ternary cathodes in lithium-ion batteries, Layered oxides can be utilized for grid storage solutions as they can deliver high capacity and hence energy density. They can also be used in EVs. However, their safety and stability is a concern. [2] Prussian Blue Analogs: Exclusive to sodium-ion batteries, these compounds exhibit a crystal structure that can easily accommodate larger sodium ions. [3 Silicates: As newcomers in the cathode landscape, silicates are gaining attention for their low cost and safety profile, though they offer low voltage. [4] Phosphates: These compounds are known for their impressive stability and safety while offering a good performance. [5] Organics: Emerging as a sustainable option, organic cathodes could allow tunable properties and high specific capacity, although their low voltage and stability are challenges to be addressed. While hard carbon leads as the anode counterpart, it’s the cathodes that are currently undergoing rapid evolution. Industry pioneers like Faradion Limited, Natron Energy, and Contemporary Amperex Technology Co., Limited are pushing the boundaries to unlock the full potential of sodium-ion batteries. As we track progress in electrode and electrolyte compositions, the sodium-ion technology is playing an increasingly important role in the energy transition.

I'm excited to share our recent scientific article on Tandem CO2 electrolysis, which has been published in Nature Communications. In this article, we present the first-ever low-temperature, neutral-pH, cathode precious metal-free tandem CO2 electrolyzer cell chain. With our tandem cell system, we've achieved significantly enhanced production rates of ethylene (increased by 50%) and alcohols (increased by 100%), along with a substantial boost in C2+ energy efficiency (up by 100%). This performance was achieved at current densities of up to 700 mA cm−2, surpassing the single CO2-to-C2+ electrolyzer cell system approach. Our study demonstrates the potential of coupled tandem electrolyzer cell systems to offer both kinetic and practical energetic advantages over single-cell designs. This innovation opens new possibilities for the direct production of value-added C2+ chemicals and fuels from CO2 feeds, all without the need for intermediate separation or purification. A big shoutout to the dedicated team behind this achievement: Tim Möller, Sven Brückner, Wen Ju, and Peter Strasser. We'd also like to express our gratitude to the EcoFuel project for making this study possible.

The development of the new solid-state ZnI₂ (zinc iodide) battery marks a significant stride in sustainable energy storage. This innovative design overcomes the limitations of traditional zinc-iodine batteries, enhancing cycle life and efficiency. The breakthrough lies in using fluorinated block copolymers as solid electrolytes, creating a stable SEI layer on the zinc anode. This prevents zinc dendrite formation and ensures prolonged battery lifespan. Symmetrical cells with this solid electrolyte have shown stable performance for 5,000 hours at 0.2 mA cm². The complete ZnI₂ battery exhibits exceptional rate performance and over 7,000 cycles with nearly 100% coulombic efficiency, translating to more than 10,000 hours of operation. Featuring a solid perfluoropolyether (PFPE)-based polymer electrolyte, this battery design presents a sustainable alternative to lithium-based options. It showcases the potential of material science innovation for efficient energy storage solutions. Future efforts will likely focus on scaling up the technology and exploring diverse applications while managing costs.

Did you know that aluminum-based batteries could be a sustainable, safe and affordable alternative to lithium-ion batteries for the energy transition? Aluminum is abundant, recyclable and has a high theoretical capacity, which means it can store more energy per weight and volume than lithium and these batteries would be safer and less flammable than their lithium-ion batteries counterpart. However, aluminum-based batteries also faced some challenges, such as finding suitable cathode materials and electrolytes. Commercial solutions could be under way.

Why someone said the Sodium-ion battery will be cost advantge in the future? 1.Raw Material Cost: Sodium, being the sixth most abundant element in the Earth's crust (2.36% abundance), contrasts sharply with the much scarcer lithium (0.002%). This abundance translates to a stable supply and lower prices for raw materials. Additionally, sodium's simpler extraction process, especially from abundant sources like seawater, adds to the cost efficiency. 2.Manufacturing and Processing Costs: As sodium-ion battery technology matures, production costs are reduced. The manufacturing process for these batteries is potentially simpler and more economical compared to lithium-ion batteries. Moreover, the scalability of sodium-ion technology promises further cost reduction as production volumes increase. 3.Transportation and Safety Costs: Sodium-ion batteries are generally considered safer than lithium-ion counterparts, potentially reducing costs associated with safety measures during transportation and storage. The lower risk of overheating and combustion means less stringent transportation regulations, further cutting logistics expenses. In conclusion, sodium-ion batteries offer a compelling cost-effective alternative in the energy storage market. Their abundance, simpler manufacturing, and safer usage profile position them as a promising solution for a range of applications. hashtag #CleanEnergy #CostEfficiency #SodiumIonBatteries #BatteryTechnology #EnergyStorage #LithiumIon #SustainableEnergy #TechInnovation #SolidStateBatteries #EcoFriendlySolutions #RenewableEnergy #EngineeringExcellence
