Which power lithium battery energy density technology enterprise is strongest?

The electrical energy released by the average unit volume or mass of a battery. Generally, at the same volume, the energy density of lithium-ion batteries is 2.5 times that of nickel-cadmium batteries and 1.8 times that of nickel-metal hydride batteries. Therefore, in the case of equal battery capacity, lithium-ion batteries will be smaller than nickel-cadmium and nickel-metal hydride batteries., lighter weight.

Battery Energy Density = Battery Capacity × Discharge Platform/Battery Thickness / Battery Width / Battery Length.

Power cell energy density technology enterprise which is strong?

BYD

Currently, BYD's lithium iron phosphate battery has a single energy density of 150 Wh, and BYD plans to continue to increase the energy density to 160 Wh. In addition to lithium iron phosphate batteries, BYD is also simultaneously developing lithium ternary batteries, and if the technology of lithium ternary batteries is combined with lithium iron phosphate batteries, some adjustments are made to the original use of graphite as a negative electrode material. Around 2020, BYD plans to increase the monomer energy density of lithium iron phosphate batteries to 200 Wh.

In addition, in terms of the follow-up ternary batteries, BYD's ternary batteries already have mass production conditions, and the current energy density has also reached 200 Wh/kg. The target of BYD ternary batteries is to reach 240Wh / kg of battery energy in 2018 and 300Wh / kg in 2020.

Wotema

The 32650 cylindrical powered lithium iron phosphate battery produced has a single energy density of 145 Wh/kg, and the next goal is to achieve 160 Wh/kg; The current energy density of the ternary battery is 200 Wh / kg and it is expected to reach the level of 300 Wh / kg by 2020.

National energy battery

As early as 2013, the energy density of the monomer of the National Energy iron phosphate and ternary batteries reached 160 Wh/kg and 200 Wh/kg. It is expected that by the end of 2017, the energy density of lithium iron phosphate batteries will reach 180 Wh/kg, PACK will reach 134 Wh/kg, and the energy density of ternary batteries will exceed 240 Wh/kg.

Jetwei Power

In terms of energy density, the company has currently mass-produced three-part soft-pack battery monomers with a specific energy of 210WH/Kg. On the basis of improving battery safety, it is expected that the company's soft-pack battery single energy density can reach 300WH/Kg in 2020, and Pack can reach 220WH/Kg after forming a group; lithium titanate batteries have a single energy density of 110 WH/Kg or more.

Smart Energy

The company's mass-produced power cell has a single energy density of 220 Wh/Kg, and PACK has a energy density of 140 Wh/Kg. At the same time, the company's BMS system can achieve level 5 protection, battery package using lightweight materials, and structural optimization.

Bic battery

In 2016, the Bic Sanyuan material power battery industry accounted for more than 30 %, ranking first. At present, the energy density of the Bic monomer core is nearly 220 Wh / kg, and the follow-up will be further increased to 300 Wh / kg.

Kanai New Energy

Karnai New Energy has been able to supply energy density 220Wh/kg core in bulk, and the system has a specific energy of more than 130Wh/kg core. At the same time, 250 Wh/kg and 300 Wh/kg product reserves have been achieved at the process and technical levels, respectively.
