# 58 / October 2017 / Focus: Batteries of the future
From cellphones and electric cars to storage batteries for apartment blocks: lithium ion batteries have taken the world by storm – and stoked the demand for electricity that is available around the clock. This poses two problems, however: firstly, high-performance batteries are flammable and have to be monitored while charging and discharging to make sure nothing happens.Secondly, the majority of lithium ion batteries come from Asia these days. The lifestyle in large parts of the world is, therefore, increasingly dependent on one supply region – much like during the oil crisis in the 1970s. It is clear that the popular lithium ion battery will eventually be replaced by new technologies. At Empa, several research teams are investigating potential solutions for the electricity conserves of the next few decades.
