According to the official report of the "Spectrum" magazine official website of IEEE, Solid Energy Systems of Massachusetts, USA, is expected to be the first company to sell semi-solid batteries. The startup company claims that it has the same weight as traditional lithium-ion batteries. In comparison, the energy contained in a semi-solid battery doubled.
Lithium-ion batteries have a powerful energy and long cycle life, but are prone to explosions that can cause casualties, leading to the recall and disabling of electronic products. Replacing flammable liquid electrolytes with inert solids such as plastics or ceramics is a safer alternative.
Hu Qichao, founder of Solid Energy Systems, said that many people are trying to find 100% perfect solid-state battery technology. Although the solid-state battery has an energy density of about 500 watt-hours/kg, which is twice that of conventional lithium-ion batteries, its shortcomings. It can only be recharged 200 times (the number of traditional battery repetitions is close to 1000). 'So we think that the semi-solid battery solution is better.'
The company uses a thin lithium anode anode made of pure lithium foil coated with a mixed polymer ceramic electrolyte to allow lithium ions to conduct ions at room temperature. These new designs allow the battery to have twice the energy density of conventional batteries and can be repeated. Charging 23000 times. Currently using advanced batteries can only maintain 20 minutes of advanced drones, with new batteries can fly for 40 minutes or more. New technology also uses plasticizers to prevent cracking, while solving the common solid-state battery Battery interface fracture problem.
The company is currently testing drone batteries and is expected to be available later this year.
