What is the difference between a lithium battery and a lithium-ion battery?

Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are generally non-rechargeable and contain lithium in a metallic state.
Li-ion batteries do not contain metallic lithium and are rechargeable. Lithium batteries, lithium ion batteries and lithium polymer batteries are different in principle.
Lithium batteries use metal lithium as the electrode, and electrons are transferred to generate current. Because dendrites are easy to generate and cause explosions, they have long been out of use.
Lithium batteries are primary batteries. Lithium-ion batteries are charged and discharged by the transfer of lithium ions, mainly using lithium-doped metal oxides as electrodes. Lithium-ion batteries are rechargeable secondary batteries.
1. Lithium primary battery is also called primary lithium battery. It can be discharged continuously or intermittently.
Once the power is exhausted, it can no longer be used. It is widely used in electronic products with low power consumption such as cameras.
Lithium primary batteries have low self-discharge and can be stored for 3 years, and the effect will be better if stored under refrigerated conditions. It is a good way to store lithium primary batteries in a low temperature place.
Note: Lithium primary batteries are different from lithium-ion batteries. Lithium primary batteries cannot be charged, and charging is very dangerous!
2. Lithium-ion batteries are also called secondary lithium batteries. It can be stored for more than half a year at 20°C, because its self-discharge rate is very low, and most of the capacity can be recovered. The self-discharge phenomenon exists in lithium batteries. If the battery voltage is kept below 3.6V for a long time, it will cause the battery to be over-discharged, destroy the internal structure of the battery, and reduce the battery life.
Therefore, long-term storage of lithium batteries should be recharged every 3-6 months, that is, charged to a voltage of 3.8-3.9V (the best storage voltage of lithium batteries is about 3.85V), and it is advisable to keep the discharge depth at 40%-60% , should not be filled. Batteries should be stored in a dry environment between 4°C and 35°C or in moisture-proof packaging. Keep away from heat sources and keep out of direct sunlight.
The application temperature range of lithium battery is very wide. It can still be used outdoors in winter in the north, but the capacity will be greatly reduced. If it returns to room temperature, the capacity can be restored.
