Blade battery energy storage principle

Why do we need blade batteries?

Blade batteries cannot achieve higher energy density in battery materials, but they have made breakthroughs in battery system integration. This solves the shortcomings of short battery life of lithium iron phosphate batteries. This is the background for the birth of blade batteries. Part 3. BYD blade battery specifications Part 4.

What are the advantages and disadvantages of blade batteries?

Another advantage of blade batteries is that they have good heat dissipation performance. We all know that batteries are particularly sensitive to temperature, which is also the main reason that limits battery fast charging time. Therefore, heat dissipation is a very important indicator for battery cells.

What is a blade battery?

Another unique selling point of the blade battery – which actually looks like a blade – is that it uses lithium iron-phosphate (LFP) as the cathode material, which offers a much higher level of safety than conventional lithium-ion batteries. LFP naturally has excellent thermal stability and is substantially cobalt free.

How much power does a blade battery pack get?

The Blade Battery pack can attain 140 Wh/kg, enabling it to qualify for the same subsidies as most ternary batteries. The present policy states that LFP battery systems will receive fewer subsidies due to low energy density (< 140Wh/kg).

What is a blade EV battery?

Unlike traditional EV batteries, which consist of many individual cylindrical cells, the Blade battery uses a single-cell format. This design allows for a greater packing density, resulting in a higher energy capacity per unit volume. The single-cell design also allows for a more straightforward, robust battery pack, reducing the risk of failure.

How does a blade battery work?

The high-voltage wiring harness and sensors of the blade battery are in the Y direction of the battery cell. Therefore, the upper box can be in direct contact with the battery core. This allows the blade battery to save 10~20mm in height compared to batteries of the same specification.
