Lithium Battery Dangers: Primary lithium batteries are unsafe and may explode; cobalt oxide and lithium ion batteries cannot be discharged at high currents, are expensive, and all have poor safety; require Protect the circuit to prevent the battery from being overcharged and discharged; the production requirements are high and the cost is high; the conditions of use are limited, and the use of high and low temperatures is very dangerous.
Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. The weight of a lithium-ion battery is half that of a nickel-cadmium or nickel-hydrogen battery of the same capacity; the working voltage of a lithium-ion battery cell is 3.7V, which is equivalent to three nickel-cad batteriesmium or nickel. -hydrogen batteries in series; Lithium-ion batteries do not contain metal. Lithium is not restricted by air transport regulations such as the ban on carrying lithium batteries on passenger planes.

Lithium battery electrode materials
1. Carbon negative electrode material. The negative electrode materials actually used in lithium-ion batteries are mainly carbon materials, such as artificial graphite, natural graphite, mesophase carbon microspheres, petroleum coke, carbon fiber, resin carbon pyrolytic, etc.
2. Tin-based negative electrode material. Tin-based negative electrode materials can be divided into two types: tin oxide and tin-based composite oxide. Oxides refer to oxidesof metallic tin in various valence states. There are no commercial products.
3. Nitride. There are also no commercial products.
4. Alloys. Including tin-based alloys, silicon-based alloys, germanium-based alloys, aluminum-based alloys, antimony-based alloys, magnesium-based alloys and others alloys, there are no commercial products.
5. On the nanoscale. Carbon nanotubes and nanoalloy materials.
6. Nano oxide. According to the latest market development trends in the new energy industry of lithium batteries in 2009, many companies began to use nano titanium oxide and nano silicon oxide to add to traditional graphite, nano oxide nanotubes. tin and carbon to significantly improve charging and discharging. capacity of lithium batteries and number of charges and dischargesges.
