The new technology of solid-state batteries can double the energy density of lithium-ion batteries

Researchers at Deakin University in Australia have shown that they have managed to use common industrial polymers to make solid electrolytes, which has opened the door to doubling the energy density of solid-state lithium batteries, which do not resist overheating. Will explode or catch fire. Dr. Fangfang Chen and Dr. Wang Xiaoen of Deakin Advanced Materials Institute claimed that they have achieved a breakthrough, “in the scientific community, the first clear and useful example of liquid-free high-efficiency lithium ion transport has been completed.” The Deakin University team stated that only existing commercial polymers are used in the new process, which means that industrial production should be'at your fingertips'. At this stage, they have already tested the button battery, the size of which is equivalent to the size of a watch battery, but the team is now working on building a pocket battery that can be used in mobile phones, and once successful, they will look for business partners Bring these solid-state batteries to the market. The team believes that in addition to making the battery safer, the solid polymer electrolyte will eventually enable the battery to use a lithium metal anode. This will be big news in the battery industry. Recently, in 'Chemical TrendsDr. Wang said that this may be a way to double the energy density of lithium batteries. In a commercial environment, the current peak energy of lithium batteries reaches about 250 Wh/kg (in Tesla's Model 3 battery pack). Increasing it to 500 Wh/kg can expand the range of electric vehicles, perhaps using smaller, cheaper and lighter battery packs. This new technology uses a solid polymer material that is weakly bound to lithium ions to replace the volatile liquid solvent normally used as the battery cell electrolyte at the time, and the liquid electrolyte is the flammable part of the battery. Dr. Chen said: 'If the profession uses our findings, I will see a future. For example, battery-related equipment can be safely packed in the luggage of an airplane. Perhaps electric cars will not cause a fire to the occupants or emergency services like they do now. risk.
