Solid-State Batteries To Achieve EV DominationWhile lithium-ion batteries have become the dominant solution for EV battery systems, they suffer from a few limitations.One of these is still not-so-great energy density, and another one is a safety issue linked to the growth of dendrites piercing the battery and the electrolyte sometimes catching fire.Both problems are expected to be alleviated with solid-state batteries, which remove the need for electrolytes and the risk of dendrites.Toyota is forecasting the usage of these solid-sate batteries by 2027 , and overall, it seems a solid candidate for the future of mobility .Still, some issue persists, notably with the garnet-type solid electrolyte, also known as Li7La3Zr2O12 or LLZO (see below).So it is good news that four researchers at McGill University in Canada announced that they created a new LLZO design that can deliver an increased amount of energy. They published their results in Cell Reports Physical Science in a paper titled “ 4.8-V all-solid-state garnet-based lithium-metal batteries with stable interface ”.Solid-State ElectrolyteLLZOIt is usually said that solid-state batteries do not need electrolytes. This is technically correct when referring to the liquid electrolyte commonly used in lithium-ion batteries.But of course, any battery still needs some sort of bridge between the anode and cathode to function. There are three types of solid-state electrolytes (SEs): ceramic, polymer, and composite SEs (CSEs).The composite solid-state electrolytes (CSEs) mix polymer SE with ionic conductive inorganic fillers like Li7La3Zr2O12 (LLZO) to facilitate lithium-ion transports.While this method is ideal for high-voltage operation in dense batteries, it suffers from poor contact with the electrode, reducing the overall efficiency.Porous LLZOWhat the researchers discovered, is that the LLZO can be made of a porous ceramic membrane, instead of the usual sense plate. In more technical terms:Here, we design a highly conductive and interface-friendly garnet-based composite solid electrolyte (CSE) comprising a cubic Li6.1Al0.3La3Zr2O12 porous framework and polyvinylidene difluoride (PVDF) with a three-dimensional continuous structure.Visually, it translates into a very complex 3D structure full of small holes at the microscopic scale:This creates a lot of surface contact for the lithium-ion, while still offering a strong adherence to the electrode.More Stable & Durable BatteriesSolid-state batteries are overall a lot more powerful and energy-dense than lithium-ion batteries. But they have been difficult to manufacture at scale so that they can last many charge-discharge cycles without losing capacity.So the researchers went on to test the batteries to see if the electrode interface they had created was as sturdy as they expected.After 200 cycles, they studied it under a microscope and found no trace of degradation, like cracking, delamination, etc.Overall, the battery prototype demonstrates excellent resistance, especially against dendrite formation.Li-Li symmetric cells based on the ceramic-based CSE can cycle stably for 1,000 h at 0.1 and 0.5 mA cm−2, indicating excellent electrochemical stability against Li-metal and even Li+ deposition (dendrite suppression).Better Safety ProfileThe drastically reduced dendrite formation, as well as the absence of flammable electrolytes, should help increase significantly the safety of lithium batteries.Because the thickness of the ceramic-based CSE is only 125 μm, this also makes this technology very competitive to create very energy-dense solid-state batteries.It should also be noted that while not simple, the technique used to create the improved LLZO does not require rare metals, rare machinery, or complex steps that are out of the ordinary in battery manufacturing.So overall, this should be an important step in boosting further the characteristics of solid-state batteries in all important aspects: stability, safety, energy density, and ease of production.Are Solid State Batteries Winning?It is not to say that solid-state batteries are certain to become the new standard for EV batteries in the coming years.Lithium-ion batteries might be able to compete as well
