Titanium disulfide is a layered material that lithium ions can move into and out of easily.

二硫化钛是一种分层材料，锂原子可以自由进出。

His group at Oxford University demonstrated that a battery using a cathode made from lithium cobalt oxide, another layered material, could produce as much as 4 V.

他在牛津大学的团队证明电池的阴极使用锂钴氧化物，这是另一种分层材料，其电池电压可以达到4伏。
