Schematics of Li + /Na + mixed-ion battery. Lithium-intercalation compounds and sodium-intercalation compounds are used for anode and cathode, respectively. During charging (or discharging), the storage (or release) of Li + takes place at anode, and the release (or storage) of Na + occurs at cathode. Chen et al.

Researchers at the University of Maryland, with colleagues at the University of Illinois at Chicago, report on a new method for expanding graphite for use as a superior anode for sodium-ion batteries in a paper in Nature Communications. Sodium (Na) is an earth-abundant and inexpensive element, and shares many properties with lithium.

A major barrier to the use of high energy capacity silicon in a lithium-ion battery is the volumetric expansion of silicon under lithiation and delithiation, which results in electrode degradation and capacity fade. Silicon (shown in grey) is capable of holding 10 times as many lithium ions (shown in pink) as currently-used anodes.

These advantages also make the mesoporous silicon a potential candidate for other applications, such as optoelectronics, drug delivery systems and even lithium-ion batteries. They then treat the material with a sodium potassium alloy. There are some processes that use sodium potassium alloy at industrial levels.

Researchers in South Korea have demonstrated new type of room-temperature and high-energy density sodium rechargeable battery using a sulfur dioxide (SO 2 )-based inorganic molten complex catholyte that serves as both a Na + -conducting medium and cathode material (i.e. catholyte). mA cm −2 ). This corresponds to an areal capacity of 4.1 mAh

A team from the University of Science and Technology Beijing is proposing a new super-valent battery based on aluminium ion intercalation and deintercalation. The battery exhibits excellent reversibility and relatively long cycle life compared to earlier Al-ion efforts, the team said. Wang et al. Click to enlarge. —Wang et al.
