Compared with other batteries, lithium-ion batteries have the following five main advantages.
1. High voltage
The open circuit voltage marked is high, typically 3.6V, while the open circuit voltage of NiMH and NiCd batteries is 1.2V.
2. Large capacity
High energy and high energy density are the core values of lithium batteries. In terms of the same energy output, the weight of lithium-ion batteries is not only half that of nickel-hydrogen batteries, but also 20% smaller. The specific capacity is roughly nickel-cadmium. The battery is 2.5 times larger than the nickel-hydrogen battery.
3. Discharge rate
The charging speed is fast, it only takes 1~2hour to fully charge the electric power and reach the best state. At the same time, the lithium-ion battery has very little leakage current. Even if it is used for 1~2 weeks, it can operate as usual. The discharge rate is <8%/month, which is much lower than 30% of nickel-cadmium batteries and 40% of nickel-hydrogen batteries.
4. Long life
It can usually be achieved more than a thousand times.
5. No memory effect
Other features include non-polluting, cost-effective, and can greatly reduce the weight of the application equipment. It is a leader in the battery industry and an ideal power source for small portable electrical equipment. However, this battery has a fatal flaw that is easy to ignite. For this reason, the Illinois Institute of Technology in Chicago, USA, can add 1.68% hexamethylene epoxide triphosphate to the electrolyte to effectively reduce its ignition point. The occurrence of explosions greatly improves the reliability of lithium batteries.
