Lithium battery development history

Lithium batteries and lithium - ion batteries are new high - energy batteries that successfully developed in the 20th century. Lithium battery generally refers to lithium battery and lithium secondary battery. The anode of this kind of battery is lithium metal, and the anode is MnO2, SOCl2, etc.

The research of lithium primary battery began in the 1950s and became practical in the 1970s. Because of its high specific energy, high battery voltage, wide operating temperature range, long storage life and other advantages, has been widely used in military and civil small electrical appliances, such as mobile phones, portable computers, cameras, cameras, etc., part of the replacement of traditional batteries.

The safety performance of lithium secondary battery is still in the experimental stage. Lithium ion battery research began in the 1980s. In 1990, Nagoura et al. developed a lithium ion secondary battery with petroleum coke as the negative electrode and LiC002 as the positive electrode. That same year, Moll and Sony announced plans to launch carbon-negative lithium-ion batteries. In 1991, the Japanese SONY battery department and energy technology company jointly developed a lithium ion battery with polysaccharide alcohol pyrolysis carbon (PFA) as the negative electrode.

In 1993, a polymer lithium ion battery (PLIB) was first reported by Bell core in the United States using the PVdF process. Domestic manufacturers of polymer lithium ion batteries also came out in the 1990s. In December 1999, Xiamen Baolong industrial co., ltd. and July 2000, Guangdong Huizhou TCL Jinneng battery co., ltd. went into production. According to statistics, worldwide lithium ion battery production growth rate is very fast.

The capacity of polymer lithium ion battery is larger than that of current liquid lithium ion battery, and because the polymer battery material is soft, the battery does not leak liquid, easy to make ultra-thin and arbitrary shape of the battery. Therefore, the polymer lithium ion battery is a small electrical appliances, such as notebook computers, mobile phones, cameras, such as the ideal power supply.

High-capacity lithium batteries used in electric vehicles,special and energy storage sectors are still strictly in the development stage. For example, there is a dispute over the route of power lithium batteries. Japan and South Korea advocate lithium manganate, while China and the United States prefer lithium iron phosphate, indicating that both are not perfect.

In 1995, Sony energy technology corp. The prototype large lithium-ion battery (100Ah), which was tested by Nissan NissanMotorCo for use in electric cars, is said to have a cycle life of 1,200 cycles, or 193,112km (120,000 miles). 1998 SahCo., France At the 9th international lithium battery conference, it was announced that the lithium ion battery (50Ah) for electric vehicles has reached the pilot production stage. These early power battery performance has been beyond, but large-scale practical needs of the improvement of supporting projects.
