  As a   Sony Rechargeable Battery Factory , share with you. Lithium battery cathode materials have become a battleground in the new energy lithium battery industry chain. As the core of lithium batteries, the performance of cathode materials directly affects the electrochemical performance of the former such as working voltage, specific energy and cycle life; not only that, cathode materials account for a relatively high proportion of the production cost of lithium batteries, about 25% to 30% . Driven by these two factors, coupled with the fact that automobiles in the global market are already in the midst of an electrification strategy, the demand and supply of raw materials has become a key link, and cathode materials have become a must for companies in the new energy lithium battery industry chain. Samsung 21700 Battery Lithium battery cathode materials have become a battleground in the new energy lithium battery industry chain The main constituent materials of lithium bat...
