Semi-solid batteries use solid electrolyte instead of organic liquid electrolyte in traditional lithium-ion batteries, which can provide higher safety and stability. Solid electrolyte has high heat resistance, short circuit resistance and chemical corrosion resistance, which can greatly reduce the risk of battery combustion or explosion.
At present, there is not enough experimental data to prove the safety of these semi-solid batteries. Although BYD, Toyota and other automobile manufacturers have published some experimental results, more research and tests are needed to verify these results.
It should be pointed out that the safety of battery technology depends not only on the design and material of the battery itself, but also on the quality control in the manufacturing process and the operation of users. Automobile manufacturers need to ensure that the production process of batteries meets strict quality standards and provide necessary use and maintenance guidelines to ensure the safety and performance of batteries.
To sum up, although the semi-solid batteries of BYD and Toyota have the potential to provide higher safety, more research and experimental data are needed to determine their real safety, and strict management is needed in the manufacturing and use process.
