What is the energy density of lithium iron phosphate battery?

At present, the energy density of the mainstream lithium iron phosphate battery and ternary lithium battery is between 200 and 300 Wh kg−1 or even <200 Wh kg −1, which can hardly meet the continuous requirements of electronic products and large mobile electrical equipment for small size, light weight and large capacity of the battery.

How to calculate energy density of lithium secondary batteries?

This is the calculation formula of energy density of lithium secondary batteries: Energy density (Wh kg −1) = Q × V M. Where M is the total mass of the battery, V is the working voltage of the positive electrode material, and Q is the capacity of the battery.

Which cathode material can raise the energy density of lithium-ion battery?

Among the above cathode materials, the sulfur-based cathode material can raise the energy density of lithium-ion battery to a new level, which is the most promising cathode material for the development of high-energy density lithium batteries in addition to high-voltage lithium cobaltate and high‑nickel cathode materials. 7.2. Lithium-air battery

What is the energy density of Amprius lithium-ion batteries?

Recently, according to reports, Amprius announced that it has produced the first batch of ultra-high energy density lithium-ion batteries with silicon based negative electrode, which have achieved major breakthroughs in specific energy and energy density, and the energy density of the lithium battery reached 450 Wh kg −1 (1150 Wh L −1).

How to improve the energy density of lithium batteries?

Strategies such as improving the active material of the cathode, improving the specific capacity of the cathode/anode material, developing lithium metal anode/anode-free lithium batteries, using solid-state electrolytes and developing new energy storage systems have been used in the research of improving the energy density of lithium batteries.

Will Hyundai be able to use lithium iron phosphate batteries?

Currently, Chinese manufacturers supply lithium iron phosphate batteries with capacities in the mid to high 200 Wh/kg range. If Hyundai is able to achieve its goal, that will give it access to the most energy-dense LFP battery cells available for its electric cars.
