Even though Toyota seems to be focusing on Hydrogen Fuel Cell vehicles as the transportation of the future, they are still working hard to develop their electrical technology, and they have quite a few developments up their sleeve. The automaker has two different powerful battery technologies in development that could both dramatically improve the performance capabilities of electric-driven vehicles, one of which is in the prototype stage already, solid-state batteries. Solid State Batteries Toyota is developing a technology known as solid state batteries and they have already produced a coin-sized prototype that manages an impressive level of energy density compared to current lithium-ion batteries. The battery manages an energy density of around 400 Watt-hours per liter, or 400 Wh/L. This is currently close to two times as dense as lithium batteries being used today, which could do great things for electronics in general outside of the automotive industry. On top of offering more energy storage capabilities, this battery can also put out a power stream about five times as powerful as lithium-ion batteries are capable of doing. That means more powerful motors can be driven using fewer batteries. This technology is expected to be released in 2020 and should be perfected enough to hit between 600 and 700 Wh/L by 2025. What Makes them Different Solid state batteries are known as such because they rely on a solid electrolyte in place of the liquid electrolyte that’s used in lithium ion batteries. Instead of nickel-metal hydride or a lithium ion, solid ceramic or a polymer is used instead. This packs more energy into a smaller area allowing for a greater storage capacity. What the Batteries Can Do With solid state batteries being at the current energy density of the prototype in development a family sedan would be able to drive for around 300 miles on a single charge. While this is quite a ways off from the 600 miles that many automakers are shooting for, this is still a huge step forward for the industry overall and something to get excited about. Lithium Air Batteries Toyota is also developing lithium air batteries, but they expect these to take about five to ten years longer to develop than solid state batteries. These batteries rely on a small cathode that interacts with oxygen and requires less materials overall. This makes it possible to squeeze even more energy into a tiny area and could allow up to 1,000 Wh/L of storage by 2030. These two advances represent major breakthroughs for the electronics industry and will make it possible to produce long-distance electric vehicles that are much more efficient than the ones we see today. It’s hard to say if they are simply hedging their bet on Hydrogen fuel-cell vehicles with this technology or if they plan to incorporate it into future vehicles to create something even more sophisticated for drivers to rely on.
