A Chinese company starts manufacturing solid-state batteries, great news

In these times, the battery is one of the most important components in our mobile phones, as well as in the automotive world. The increase in electric vehicles is a reality, and the goal by 2030 is for its market share to be at least 30%. Improving current battery technology is necessary to improve their autonomy and safety..

Solid-state batteries have been around for a while, and a Chinese star-up claims to have started production of them. More than 144 million dollars invested in a technology of the future, which we hope to see on our cell phones in the long run.

Why is it necessary to change the batteries

The batteries we have at the moment are lithium-ion, built several cells in which energy is stored. The main electrolyte in these batteries is a lithium salt, from whose ions the electrochemical reaction arises that allows energy to be moved from the positive to the negative pole.

While these are the most commonly used batteries, they have several problems. Its average life is about 2 years in the case of mobile phones, and just over 3 years in the case of larger units for other products. Their load cycle is from 300 to 1000, and the materials of which they are composed make them a flammable product, with risk of explosion at high temperatures. Otherwise, lithium batteries also perform worse in extreme cold conditions, with up to a 25% decrease in its duration.

Solid-state batteries are made up of lithium metal. This compound is not flammable, it allows higher density in the same size, and therefore, more capacity. Qing Tao Energy Development Co, a Chinese startup that emerged from Tsingua University –one of the best known in China–, has started the first solid state battery production line. According to the management of the emerging company, 144 million dollars have been invested in said line, with a current capacity of 100 MWh per year and with a forecast of increasing to 700 MWh in 2020.

Right now, they are using the batteries for “special equipment and high-end digital products,” and they are in talks with large automakers. While the production line is still in short supply, There can be no better news than knowing that these batteries are already in the works. It is a long-term project, which we will not see materialize on the smartphone for a few years. However, the jump from lithium-ion to solid-state battery is inevitable.
