In the Special Project Implementation Plan for Promoting Strategic Emerging Industries “New Energy Vehicles” (2012–2015), power batteries and their management system are key implementation areas for breakthroughs. However, since 2016, the Chinese government hasn’t published similar policy support.
Actual cars powered by solid-state batteries seem to be perpetually on the horizon: Toyota’s original target date for commercializing them in the early 2020s has now slipped to the late 2020s, for example. When it comes to batteries, “Toyota has said a lot of things in the last ten years, none of which have come through,” cautions Ceder.
NEVs can reduce damages to the environment and guarantee social and economic development. They are the trend of the automotive industry. However, it is worth mentioning that the current development status of NEV batteries is not ideal.
In the late 19th and early 20th centuries, lead-acid batteries were among the earliest battery types utilized in electric vehicles. They helped to advance the development of electric propulsion technology by supplying the required electricity for the first electric automobiles and trucks.
Additionally, solid-state batteries have a higher energy density, which could extend the driving range of electric cars. In addition, compared to conventional battery technologies, they provide longer lifespans and increased overall efficiency with quicker charging times.
Today, most electric cars run on some variant of a lithium-ion battery. Lithium is the third-lightest element in the periodic table and has a reactive outer electron, making its ions great energy carriers.
