Mercedes plans to adopt solid-state battery technology in city buses

According to foreign media reports, Mercedes-Benz said: “Overall, vehicles with standard solid-state batteries will not appear until around 2025. But Mercedes-Benz is faster: the new eCitaroG is available worldwide. The first mass-produced city bus equipped with solid-state batteries in its class. 'The outside world generally did not expect that solid-state battery technology could achieve mass production levels in a short period of time. Toyota has previously stated that it will wait until 2025 before the company will start producing solid-state battery cars, with limited output. Fisker also postponed plans to use the technology. The development of solid-state battery technology has not been smooth sailing. Compared with other manufacturers' solid-state battery technology, Mercedes-Benz's technology seems a bit 'compromise.' When talking about solid-state batteries before, manufacturers have been emphasizing its ultra-fast charging speed (from zero to full charge in about 15 minutes) and higher energy density. As for Mercedes' solid-state battery, it is reflected in the higher energy density (25% higher than the company's latest generation of lithium-ion battery technology), but the company said that its solid-state battery's fast charging capacity is limited. If you want to buy a fast-charging bus, you should consider Mercedes's lithium battery models. However, in terms of mileage, lithium batteries cannot be compared with solid-state batteries. The company said its solid-state battery pack has a capacity of 441kWh, while its lithium battery has a capacity of 396kWh. The company has not announced the cruising range of the new solid-state battery models, but it is estimated that the cruising range of the solid-state battery models should be 10% higher than that of the lithium battery models. Another advantage of solid-state batteries is their longer service life. Mercedes offers a longer warranty period for solid-state batteries: 10 years or 280MWh of power delivery per battery pack. Mercedes claimed that the company 'not only in the field of buses, but also in the global automotive manufacturing field are in a leading position in technology.' But Mercedes has not yet revealed its plans to use solid-state batteries in its production cars. However, in any case, solid-state battery technology is beginning to be used in the field of public buses, which is still gratifying news, even though the battery capacity is temporarily limited.
