Recently, researchers at the University of Texas at Dallas may have found a way to solve the problem of thermal runaway (that is, excessive heat accumulation) in lithium-ion batteries. The research team said that after solving the problem of battery overheating, the battery capacity can be increased by 20%. -30%, and can also reduce the chance of battery fire and explosion. This discovery may change the way manufacturers produce batteries.
Recently, Zhang Lei, deputy to the National People's Congress and CEO of Envision Group, said that there have been many electric vehicle fire accidents in China, so it is recommended to strengthen power battery safety standards. The continuous accumulation of battery heat is one of the causes of battery fires and explosions. The research team at the University of Texas believes that the problem of battery thermal runaway is not inside the battery, but on the surface of the battery's positive electrode material. When the battery is continuously charged, the battery surface material It begins to degrade and the energy released will cause the battery to heat up, which may cause safety issues.
In addition, during the continuous charging of the battery, oxygen is released from the surface of the battery material. The transmission path of lithium ions from the inside to the outside of the battery may be blocked by the metal nickel dust generated with the release of gas. When a blockage occurs, the lithium ions entering and exiting the battery will be blocked. cannot be transferred, resulting in a rapid decrease in battery capacity. The leader of the research team said that a special oxide coating can be added to the surface of the battery to solve the problem of battery thermal runaway. This move can also increase the battery capacity by 20% to 30%, which may change the way manufacturers produce batteries. Way. (Source: newelectronics; text/Autohome You Dongqing)
