The most common design uses an organic electrolyte and lithium-cobalt electrode. While safe under typical operating conditions, the use of an organic electrolyte subjects the battery user to certain risks; in particular, Li-ion liquid batteries are explosive when exposed to air and subject to thermal runoff, making them highly sensitive to any physical damage. The use of cobalt also poses a moral concern, as the mining and sourcing of cobalt is geographically restricted and most commonly sourced from countries that have a history of foreign exploitation and child labor. An all solid state battery is suggested as a possible alternative battery that reduces operation risks and maintains similar performance characteristics. Lithium-lanthanum-zirconium oxide is presented as a suitable electrolyte replacement.
