2. Compared with Ni-MH battery, the working voltage of Li-ion battery is relatively high, and its specific energy is three times that of Ni-MH battery. Lithium-ion battery has the advantages of small volume, light weight, long cycle life, low self-discharge rate, no memory effect and no pollution.
3. Lithium-ion batteries can be divided into two types: lithium-ion batteries and lithium polymer batteries. The cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium nickel oxide, lithium manganese oxide and lithium ferrous phosphate, and the cathode materials mainly include graphite and lithium titanate.
Extended data:
1. Compared with Ni-MH battery, lithium-ion battery has a relatively high working voltage and a large specific energy, which is three times that of Ni-MH battery. Lithium-ion battery has the advantages of small volume, light weight, long cycle life, low self-discharge rate, no memory effect and no pollution. The performance index of single battery has a wide range, because there are more electrode combinations in lithium-ion batteries, so there are some differences in performance.
2. Lithium-ion batteries can be divided into two types: lithium-ion batteries and lithium polymer batteries. The cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium nickel oxide, lithium manganese oxide and lithium ferrous phosphate, and the cathode materials mainly include graphite and lithium titanate.
