HOME / What is the material of the short knife battery - RADIO-ENERGY
Its upper cover adopts a composite structure of PCM composite material and DP980 high-strength steel, which not only ensures the strength and rigidity of the structure, but also has good insulation, pressure resistance, fireproof, heat insulation and corrosion resistance.
In terms of material system, the positive electrode material of the short knife battery adopts lithium iron phosphate with high temperature resistance, strong safety and stability, and better cycle performance; Thermal shrinkage ability, to avoid large-area short circuit
Using multi-element doped electrode materials, combined with the battery''s smaller size and low internal resistance has given the New Short Blade EV Battery Technology a reduced internal chemical reaction rate
Aegis short knife battery adopts a high heat-resistant separator with high strength and high thermal stability, a high-safety electrolyte with more stable film formation, higher compactness and higher safety, and adopts the appropriate electrode surface density and
According to the official introduction, the battery cell of the shield short knife battery is 8 times higher than the national standard, and 8 steel needles with a diameter of 5mm are punctured at the same time and kept for 1h, and the battery cell does not smoke, fire or
According to reports, the short knife battery is based on laminated long and thin cells, and adopts the new PACK solution of LCTP. Compared with the traditional module
The Short Knife battery has ultra-fast charging performance, which can be charged to 80% in 17 minutes, with an average charge rate of 2.45C. This is due to its unique physical properties, smaller internal resistance, and the optimization and upgrading of the
A lithium iron phosphate battery, Geely claims it has best-in-class battery life, charging speed – and ultimate safety. Geely''s short blade battery is 580 mm long which is
In April 2019, SVOLT publicly displayed a short knife battery with a length of 600mm. This battery has 4 sizes, ranging from L300-L600, can cover the global charging range of 1.6-4C, and can be applied to passenger cars, commercial vehicles, energy storage, construction machinery, non-high-speed trams and other global scenarios.
And it can be applied to the global chemical system without cobalt, ternary and lithium iron phosphate. According to reports, the short knife battery is based on laminated long and thin cells, and adopts the new PACK solution of LCTP.
Such results are possible because the short blade battery uses “a high-strength, high-thermal stability, high-heat-resistant diaphragm, with a highly stable separator paired with safe electrodes resulting in higher energy density and safety.”
Geely's short blade battery is 580 mm long which is about 40% shorter than a traditional long blade battery which results in less internal resistance and heat generation while increasing volume utilization by 50%. The short blade battery in testing has achieved 3,500 charging cycles.
The energy density is increased by 9%, the charge of the whole package is increased by 24%, the PACK components are reduced by 20%, and the cost is reduced by 10%. Knife battery has the advantages of high compatibility, high adaptability, high security and long life.
Firstly it seems the official name in English is just 'New Short Blade EV Battery Technology' according to Geely who don't mention the Aegis name. Although the most important specification is still the 192 Wh/kg energy density, there are now many more elements known about the battery, its capabilities and its safety.
