Lithium Battery Early Research And Development

The earliest lithium battery used in pacemakers. Lithium  self-discharge rate is very low, the discharge voltage is flat and so  on, making implantation of the human pacemaker to long-term operation  without recharging. Lithium batteries are generally higher than the nominal voltage of 3.0 volts, more suitable for integrated circuit power supply. Manganese dioxide battery, it is widely used in calculators, digital cameras, watches.
In  order to develop more excellent performance varieties, people have  studied a variety of materials to create an unprecedented product.
1992 Sony successfully developed lithium-ion battery. Its  practical, so that people's mobile phones, laptops, calculators and  other portable electronic devices, weight and size greatly reduced.
