    摘要: A method for testing a lithium ion battery is disclosed. An under-test lithium ion battery including a cathode active material is provided. A reference voltage value is set according to the cathode active material. The under-test lithium ion battery is over charged, while an actual voltage change of the under-test lithium ion battery is tested during the over charging. A maximum voltage value is recorded before a first decrease in the actual voltage change of the under-test lithium ion battery during the over charging. The maximum voltage value is compared with the reference voltage value. A method for evaluating a safety of a lithium ion battery is also disclosed.

    摘要: A method for making a lithium battery cathode material is disclosed. A mixed solution including a solvent, an iron salt material, and a phosphate material is provided. An alkaline solution is added into the mixed solution until the mixed solution has a pH value ranging from about 1.5 to 5. The iron salt react with the phosphate material to form a plurality of iron phosphate precursor particles which are added in a mixture of a lithium source solution and a reducing agent to form a lithium iron phosphate precursor slurry. The lithium iron phosphate precursor slurry is heat-treated.
