Abstract
Description
technical field
[0001] The invention relates to the technical field of lithium batteries, in particular to a lithium iron phosphate lithium polymer battery that can be charged and discharged with a large current. Background technique
[0002] With the development of science and technology and the progress of electrochemical materials and process technology, people continue to research and develop new battery materials and new batteries. Following nickel-cadmium and nickel-metal hydride rechargeable batteries, rechargeable lithium-ion batteries were developed in 1991, and polymer lithium batteries with better performance were introduced in 1995.
[0003] The existing high-rate high-current charging and discharging lithium batteries use lithium cobalt oxide, ternary, and lithium manganese oxide as the positive electrode, and graphite as the negative electrode. The problems of the existing technology are: 1. Insufficient high-current discharge capacity; 2. Poor safety , In par...
