Considering energy density, charging speed, lifespan, stability, and intelligence, lithium batteries currently represent the ideal choice for intelligent robots.
Rechargeable batteries are vital in the domain of energy storage. However, traditional experimental or computational simulation methods for rechargeable batteries still
However, they have lower energy storage capacity than batteries, which limits their use as a primary power source. Instead, they are often paired with batteries to enhance performance.
Mobility gives robots more flexibility, but at the cost of needing to recharge their energy sources — in most cases, some form of battery. The compact nature of smartphones can fool us into thinking batteries are featherweight objects.
Mobile robots on legs, however, can’t tolerate such massive batteries. Boston Dynamics, a robotics company in Waltham, Massachusetts, sells a four-legged dog-size robot called Spot that weighs about 32 kg — one-eighth of which is batteries. But, the company states it has a typical run-time of only 90 minutes.
For mobile robots to be more capable workers, their batteries will need greater energy density — that is, they will need to pack more watt-hours of energy into fewer kilograms of mass.
Solid-state batteries, “offer the possibility of achieving the highest volumetric energy density in robotic applications [in which] space is limited”, she says. They also offer unique flexibility in packaging and can operate at extreme temperatures, which is important for some special-purpose robots.
That meant it took a one kilogram battery to power a (then standard) 60-watt incandescent bulb for one hour and 20 minutes, making it the best battery available. Now, typical commercial lithium-ion batteries carry three times more energy per kilogram. But even such energy-packed batteries are too hefty for a walking robot to lug around.
However, robots must carry the energy they use, and batteries weigh more and occupy more space than fossil fuels. An electric car, for example, needs a battery pack much larger and heavier than a fuel tank. When lithium-ion batteries reached the market in 1991, they provided 80 watt-hours of electrical energy per kilogram of battery weight 1.
