Using Advanced Battery Design to Truly Electrify Transportation"

As climate change concerns continue to drive interest in clean energy and our daily lives become increasingly digitized and dependent on electronics, electrification has become a widespread trend across almost every industry. The problem is that battery innovation hasn’t kept pace with the electric revolution. Charging time, available capacity, lifetime degradation, and costs are key performance areas that are lacking in batteries today.
While most efforts to enhance battery performance to date have been focused on battery chemistry, this has only led to incremental changes over the past 30 years. The key to the next step-change in battery performances lies within its structure.
This is what Addionics is doing - changing battery architecture to allow the next step-change in battery performance, to any battery chemistry, existing or emerging.

Tailor-made REALSi for high-performance Li-ion batteries

Today, battery performance is limited by active materials. Graphite storage ability is one of the bottlenecks we can solve using Silicon (Si). Our nanoSi and microSi are based on elemental Si; we call our materials REALSiTM, which is not an oxide, nor produced by Silane gas. Advano converts metallurgical Si, including scrap, into battery-grade REALSiTM using proprietary material science technology. REALSiTM offers tailor-made solutions to both solid-state and liquid-electrolyte batteries. We are open to partnerships to accelerate the commercialization of real Si. The next major evolution in batteries is real Si; our team envisions having REALSiTM in every battery.

Toward advanced LMP® batteries : commercial generations and innovation trends

BlueSolutions has been commercializing all-solid state batteries since 2011. EVs, buses and stationary applications are the main targets of its research and development program. After more than 15 years, this Bolloré group subsidiary masters all the industrial processes for the production of a unique solid state battery technology. The know-how goes from the transformation of the lithium ingots to the integration of the battery packs within the applications. Importantly, a low-ecological footprint process has been stated for both the positive electrode and the polymer electrolyte manufacturing.
In order to get incomparable energy densities, today, all the industrial actors of lithium batteries are hardly working on the lithium metal technology. In this context, BlueSolutions has a unique 10 years feedback regarding both the behavior of this special anode and of the solid-state electrolyte.
After having spread the first pack generation for 8 years all-over the world, an optimized 650V battery pack addressing the e-buses market is being delivered for one year. To match with customers expectations this new generation offers optimized performance and a very long cyclability. In the meanwhile, BlueSolutions has already started working on its future generation products. While the current battery is LFP-based and cycles at a nominal temperature of 80°C, a lot of efforts are dedicated to improve the actual chemistry. Research programs are conducted on the development of a new positive electrode with higher energy density, new electrolytes that will be compatible with high-voltage materials and which have high conductivity at ambient temperature and optimized lithium electrode. In fine, the goal is to keep the intrinsic safety of the polymer solid electrolyte, while benefiting from the promising performances of new electrode materials.

Advances in Carbon Conductive Additives for LIB Applications

Through a broad portfolio of advanced carbons that includes carbon nanotubes (CNT), carbon black (CB), and carbon nanostructures (CNS), Cabot Corp. has brought the world leading solutions of conductive carbons for lithium ion batteries (LIBs).

Cabot’s research and development team has worked to optimize the usage and function of conductive materials in LIBs. In cathodes, high aspect ratio CNTs, show clear benefits in imparting electronic conductivity at the lowest loadings across an electrode film. While, aciniform carbons, CBs, can make many contact points with lithium containing active materials for efficient ionic conductivity, as well as provide the space necessary for Li+ transport, while balancing the cost and processability challenges of CNTs. In silicon containing anodes, CNS is a new class of novel crosslinked CNT materials that greatly improve the cycle life of the cell. This has been shown through electrochemical testing of model cells.

Conductive carbons continue to be a key material technology in LIB. Cabot continues to work to optimize their function in LIBs with the goal of enabling LIB makers to develop winning cell designs by pushing developments in energy density and cycle life among others.

Nano-porous silicon for high-energy silicon-dominant batteries

A major improvement for the next generation of Li-ion batteries is the introduction of silicon as material for the anode, bringing capacity and fast charging to the next level. The biggest challenge of applying silicon-dominant anodes in Li-ion batteries, is silicon's tendency to expand during cycling.

E-magy has invented and manufactures micron-sized silicon particles with nanopores that overcome this challenge by containing that expansion within the nanopores themselves. Li-ion batteries with anodes made of E-magy silicon hold 40% more energy than those made of graphite. It's the low-cost, drop-in solution compatible with existing production lines that the EV industry needs – as currently verified by R&D managers of more than a dozen leading automotive and battery manufacturer brands.

Interface Stability in Solid-State Batteries

Solid-state batteries combining an alkali metal anode and a high-voltage cathode have the potential to double the energy density of current-generation rechargeable batteries. We recently demonstrated the integration of hydroborate solid electrolytes with a 4 V class cathode through in-situ formation of a passivating interface layer. Combined with their high ionic conductivity > 1 mS/cm at room temperature, low gravimetric density 1.2 g/cm3, low toxicity, high thermal and chemical stability, stability vs lithium and sodium metal, soft mechanical properties enabling cold pressing, compatibility with solution infiltration, and potential for low cost, hydroborate electrolytes represent a promising option for a competitive next-generation solid-state battery technology.

Commercial Ready High Energy Density Ultra-Fast Charge Cells

Why bother with fast charge for EV batteries? Charge rate goes beyond driver convenience - it addresses core EV adoption issues such as addressing the fact that only 20% of cars have access to overnight charging, fast charging helps improve existing infrastructure utilization, and it supports drivers becoming more comfortable with less expensive vehicles that have shorter range lowering the price for those vehicles. Enevate is a battery technology company supplying breakthrough Extreme Fast Charge Technology with its pure silicon-dominant cells that are solving these crucial EV adoption issues.

Cathode and anode considerations in the development of all solid-state Lithium battery

A stable solid-state electrolyte material is only part of the solution to an all-solid- state Lithium battery. Li ionic conductivity in cathode is as important for energy density, power density and charge rate. The morphology of metallic lithium formed on electrolyte surface when charging is a major factor controlling the safety and cycle life.
This presentation will discuss the cathode and anode development at Front Edge Technology for a LiCoO2/LiPON/Li battery system.

The multilayer approach to solid-state battery electrolytes - Transforming traditional battery architecture

Solid-state battery cells offer the ability to host high energy density lithium metal while affording safety above that of state-of-the-art lithium-ion cells due to the use of non-flammable electrolytes and dense layers that cannot be easily punctured by lithium dendrites. Ion Storage Systems (ION) employs a high-ionic conductivity garnet-based electrolyte capable of lithium metal plating without degradation at a wide range of operating temperatures.
In many solid-state cell architectures pursued to date, lithium metal plating directly leads to cell internal volume changes. Ensuring consistent lithium plating over a planar surface necessitates external compression which can add to cell and pack overhead costs while decreasing the overall specific energy density of the system as a whole. ION’s solid-state electrolyte is incorporated into cells in a bilayer structure that allows lithium to plate within the confines of a porous ceramic layer which is sintered on a cathode-separating dense ceramic layer. This structure enables constant-volume cells which can host a multitude of cathodes and enable simplified application integration, high energy density and prolonged cycle life.

Micro to Giga Scale: Different Materials, Processes and Challenges

Solid State Batteries are expected to outperform incumbent liquid-based battery technologies thanks to potential safety and performance advantages. SSBs have the potential to improve and even enable new application over a wide Wh-level range: from micro-batteries powering Augmented Reality smart contact lenses and perpetual Internet of Things sensors; to pouch cells providing safer and lighter power to cordless domestic devices and longer range to electric vehicles and new aerospace applications. Yet, after a few decades of R&D, the commercialisation of small SSB is only recent and that our larger format pouch cells still around the corner. This presentation will compare and contrast the various challenges and choices of chemistries, processes and engineering solutions necessary for the development of mWh level micro batteries to the full commercialisation of SSB modules at GWh level.

R2R Activated Dry Electrode Process for Cost-Effective Production of Solid-State Batteries

Solid state #electrolytes (SSEs) can improve safety of batteries due to the reduced possibility of thermal runaway that is more likely to occur in the presence of liquid electrolytes used in lithium ion batteries. However, lack of scalable processes allowing to produce SSEs with the necessary combination of thickness, uniformity, interfacial impedance and mechanical strength, hinders commercialization of solid-state batteries (SSBs).

Whether as glass or in ceramic form, SSEs usually require high temperature sintering or vapor deposition to consolidate the films and manage interfacial impedance. The resulting films are brittle, and available manufacturing methods are limited to production of tiny cells with low capacity.

LiCAP Technologies, Inc. has a patented Activated Dry Electrode technology, which makes processing of battery materials more cost-effective and sustainable and, is uniquely suitable for handling of sensitive SSB materials. R2R Activated Dry Electrode process is already proven on industrial scale in world’s fastest manufacturing of ultracapacitor electrodes and has been piloted in R2R production of electrodes for lithium-ion batteries. In 2022 LiCAP will launch development of scalable R2R process for the solid-state battery industry.

Opportunities for cathodes in commercialized solid-state batteries

As vast investment continues to pour into the solid-state battery development arena, many automotive OEM’s are projecting Start of Production within the next five years. Although there is no clear winner for the solid-state electrolyte, room temperature lithium-ion conductivity comparable with that of the liquid carbonate incumbent has been demonstrated at the laboratory and pilot plant scales. There are multiple options for the anode, ranging from thin lithium metal to “anode-less” in-situ generation to carbon-free high-loading silicon. Most work on the cathode has been focused on supply for current lithium-ion battery configurations, without recognizing the huge opportunity the move to solid-state provides, enabling lithium-free and high voltage options as well as the possibility of step-change reductions in cost. This talk will provide an overview of current developments in cathodes and project likely winners as solid-state batteries near commercialization.
