![]() ![]() Long-lasting, quick-charging batteries are essential to the expansion of the electric vehicle market, but today’s lithium-ion batteries fall short of what’s needed - they’re too heavy, too expensive and take too long to charge.įor decades, researchers have tried to harness the potential of solid-state, lithium-metal batteries, which hold substantially more energy in the same volume and charge in a fraction of the time compared to traditional lithium-ion batteries.

The second electrolyte, (brown) is less stable with lithium but appears immune to dendrites. It does not store any personal data.The first electrolyte (green) is more stable with lithium but prone to dendrite penetration. ![]() The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies.

SVOLT SUCCESSFULLY DEVELOPS SOLID-STATE CELL WITH SULPHIDE-BASED ELECTROLYTE, Frankfurt am Main/Changzhou, August 30, 2022 READ the latest Batteries News shaping the battery market SVOLT’s innovations in the production of the first batch of 20Ah sulphide-based solid-state prototypes point the way to the future of electromobility.” This success illustrates SVOLT’s leading position in battery technology. “We are proud that we are the first battery manufacturer to have developed prototypes with up to 20 Ah. The development of solid cell technology with sulphide-based electrolyte is a major challenge. Dominik Lembke, Director Product Development Europe: These cells have a five percent higher energy density, ten percent longer service life and 15 percent lower costs than cells of the same size produced in the winding process. In April 2019, for example, the company launched a novel prismatic cell architecture with stacked electrodes. ![]() SVOLT is constantly developing its lithium-ion batteries and battery systems for electric vehicles and energy storage systems and bringing them to mass production. SVOLT plans to further expand its research and development activities in the field of solid-state batteries as well as in new process technologies in order to further develop the technological foundations for mass production. Since then, it has already applied for 187 patents. SVOLT’s Wuxi Lithium Battery Innovation Center and the Ningbo China Institute of Materials Technology and Engineering of the Chinese Academy of Sciences established a joint research center for solid-state battery technology in April 2021. Progress in the development of solid-state batteries Together with top scientific institutes, the battery manufacturer is overcoming the technical challenges that still stand in the way of the breakthrough of the solid-state battery: a high conductivity of the solid-state electrolyte and the interface layers, the maintenance of stable contact between the interfaces over long periods of time and the efficient transfer of lithium ions at the interface, even at high C-rates. SVOLT employs its own research and development team for the further development of this important future technology. These test conditions typically cause thermal runaway of the cell in liquid electrolyte cells with a high energy content – the new 20Ah cells from SVOLT, on the other hand, survived the tests unscathed. ![]() This was demonstrated by successfully completed abuse tests, such as a 200☌ hot box test and a nail penetration test. The cells with sulfide-based solid-state electrolyte are superior to cells with liquid electrolyte in terms of energy density, charging speed, safety, cycle stability and temperature resistance. With this energy density, vehicles with a range of over 1,000 kilometers can be realized. The SVOLT solid-state cells have an energy density of 350-400 Wh/kg. Solid-state cells are superior to liquid lithium batteries ![]()
