Are silicon anodes the new future of Lithium ion batteries? In traditional lithium-ion batteries, the anode is composed of graphite, which has a limited capacity for storing lithium ions. As a result, graphite anodes can only store a certain amount of energy before they become saturated. Silicon anodes, on the other hand, have a much higher capacity for storing lithium ions, which means they can store more energy in the same amount of space. However, silicon anodes have some major drawbacks.They tend to expand and contract during the charging and discharging process, which can cause the anode to crack and degrade over time. Also, silicon surface consumes too much electrolyte to form a solid electrolyte interface. Here comes the story of Amprius, which is a leader in manufacturing lithium-ion batteries these days. It has addressed these challenges by using silicon nanowires in its anodes. The nanowire structure allows some expansion and contraction without causing the anode to crack or degrade. Additionally, the startup has developed a proprietary manufacturing process that enables the company to produce the nanowires at scale while maintaining high quality and consistency. Amprius’ batteries have demonstrated up to 30% higher energy density than conventional lithium-ion batteries as well as improved cycle life. Several leading automotive and battery manufacturers have partnered with Amprius to integrate its technology into their products, and the company has over 30 patents! #BatteryInnovation #CleanEnergy #ElectricVehicles #Sustainability

Solid-state batteries differ from lithium-ion batteries in their construction. While lithium-ion batteries use liquid electrolytes to transport ions between the anode and cathode, solid-state batteries utilize solid electrolytes. This innovation eliminates the risk of leakage or combustion, making them safer and more stable. Additionally, solid-state batteries have the potential to provide higher energy density, longer lifespan, and faster charging times. These advantages make them ideal for a wide range of applications, from consumer electronics to electric vehicles.

Following our press release earlier today with Koch Modular. Amongst the various silicon anode technologies, SINANODE is unique. The technical key differentiation of SINANODE is the ability to enhance EV-grade graphite anode materials by fusing nano-silicon into the pores. No other patented silicon anode technology does that. The business key differentiation of SINANODE is that is lowers the cost of EV cells, thanks to a very efficient process, inexpensive precursors and low factory capital equipment costs. The aim is to enable more affordable EVs with better batteries. https://lnkd.in/gZyM7_p7

We've got another #PowerUpdate for you. PowerCo and QuantumScape have entered into an agreement to industrialize solid-state batteries as the next-generation technology. 🔋  QuantumScape is a California-based startup which was founded in 2010 as a spin-off from Stanford University to develop solid-state batteries. Their technology platform is based on the company’s proprietary solid-state ceramic separator, which enables the use of a pure lithium-metal anode. This is a transformative innovation that is designed for exceptional energy and power density, fast charging and a robust safety profile.  With the new agreement, a large, dedicated team composed of experts from both companies, will execute the industrialization activities. Given successful technical progress, PowerCo can produce battery cells based on QuantumScape's solid-state technology with up to 40 gigawatt-hours (GWh) per year.  The agreement supersedes an earlier joint venture between the Volkswagen Group and QuantumScape to co-manufacture batteries. Both companies are convinced that the new agreement represents the fastest way to achieve gigawatt-hour-scale production of solid-state technology.

Lithium-ion batteries are the dominant power source for many devices, but safety is a key concern. To address this, companies are developing innovative technologies to enhance battery safety. In my next 3 LinkedIn posts, I'll showcase 3 innovative technologies that ensure battery safety. To design a safer lithium-ion battery, you either need to modify the cell during manufacturing or manage the cell's operation from the outside to ensure it operates within safe limits. Enovix Corporation has created BrakeFlow™, a manufacturing technique that significantly increases tolerance against thermal runaway from internal shorts in lithium-ion batteries, without compromising energy density. This is an example of modifying the cell during manufacturing to improve safety. Another approach is managing the cell's operation from the outside to keep it within safe limits. Solid-state batteries are also a promising technology, as they use solid electrolytes instead of flammable liquid electrolytes, making them inherently safer than traditional lithium-ion batteries. While still in development, solid-state batteries could enable more compact, faster-charging, and longer-lasting batteries in the future. Let's continue to push the boundaries of technology and make a safer, more sustainable future for all. #BatterySafety #Innovation #EnergyDensity #ThermalRunaway #BatteryTechnology

🔋A high-performance lithium-metal solid-state battery has been developed within the framework of the Horizon 2020 SOLiDIFY consortium, comprised of 14 European partners. The prototype battery, manufactured in a state-of-the-art battery lab at EnergyVille, Belgium, features a unique "liquid-to-solid" processed electrolyte, jointly developed by imec, Empa and Solvionic. The battery boasts an impressive energy density of 1070 Wh/L, well above the 800 Wh/L for current lithium-ion batteries. This achievement was realized through careful evaluation and optimization of new materials and advanced coatings. For the prototype’s electrolyte, a polymerized ionic liquid-based solid nanocomposite material was used, enabling a unique “liquid-to-solid” solidification approach for which Empa has filed a patent application. The manufacturing process, which is both cost-effective and adaptable to existing lithium-ion battery production lines, paves the way for commercially viable solid-state lithium-metal batteries for electromobility. #lithium #battery #solidstate #horizon2020 #emobility

Traditional battery packs use cylindrical single cells, but the gaps between the cells are large, wasting a lot of space, through research and development BYD invented its "blade battery" a product based on LFP technology (which it is good at, with a large global market share). The blade battery uses large cells with a length of more than 0.6 meters developed by BYD. The battery cells also evolve towards large capacity, but the shape of the cells is flatter and narrower, and they are neatly arranged together, like "blades", thus the why they are called blade batteries. The blade battery has a longer circuit, a larger surface area, better heat dissipation, and saves more support structures, which increases the space utilisation by nearly 20% compared to the traditional arrangement method.
