This article provides an interesting take on Tesla's acquisition of Maxwell Technologies, an ultracapacitor and energy storage materials company. Whilst ultracapacitors can be used in conjunction with lithium-ion batteries in vehicles for short duration, high power requirements, it seems Tesla's main interest is in Maxwell's electrode technology. This dry electrode technology can increase the energy density of lithium-ion cells and improve discharge rate capabilities. This could prove a significant step in further increasing the range of EVs leading to increased global adoption. Certainly an interesting acquisition to keep an eye on.
