Solid-state batteries could be re-charged up to seven times more, giving them a potential lifespan of ten years as opposed to the couple of years a lithium-ion battery is expected to effectively last for. Having a solid electrolyte effectively bypasses this problem.įinally, the use of the solid-state electrolyte means the batteries can withstand more discharge and charge cycles than lithium-ion batteries, as they don’t have to suffer electrode corrosion caused by chemicals in the liquid electrolyte or the build up of solid layers in the electrolyte that deteriorates battery life. Exothermic reactions in lithium-ion batteries can cause them to get hot, expand and potentially rupture spilling flammable and hazardous liquid electrolyte in some cases this has caused minor explosions. Safety is another advantage solid-state batteries claim to offer. It’s little wonder that solid state is most quoted by performance car manufacturers Bentley sees the technology as its primary way to make electrification work for them.
They are also expected to charge faster.īetter efficiency and energy density means solid-state batteries don’t require the cooling and control components that lithium-ion batteries do either, and that means a smaller overall footprint along with more chassis freedom and less weight. That means powerful and longer range electric cars or more compact and lighter EVs.
That means more powerful batteries without extra space, or more compact battery packs without compromising on power. Thanks to the solid electrolyte having a smaller footprint, solid-state batteries promise some two to ten times the energy density of lithium-ion batteries of the same size. What makes solid-state batteries the next big thing? As such, work is being done to allow them to power larger devices and be recharged. Solid-state batteries have been around for a while, but are only used for small electronic devices like RFID tags and pacemakers and in their current state are non-rechargeable.
