History of Ni-MH

6

Ni-MH has been introduced on a large scale at the beginning of the 90’s

to offer more energy density vs Ni-Cd.

Huge volumes of Ni-MH in the whole 90’s due to cellular phones

Ni-MH robustness and very long life has been demonstrated in the Toyota

Prius.

In the 2000’s, Li-ion has replaced Ni-MH in many applications, due to

strong improvements in:

Energy density

Power

Weight / Flat shape

During this decade, new Ni-MH chemistry makes this technology more

and more popular for demanding markets:

Thousands of cycles

Very large temperature range

R&D Ni-MH Program

16

3 main axes for R&D

Ni(OH)2 high performance

Higher capacity Ni(OH)2

Specific formulation to improve charge efficiency up to 80°C

Cooperation with BASF Ovonics

New alloy

AB5: Formulation under testing to improve corrosion resistance

A2B7: different compositions under testing for cycling

New alloy composition for low temperature

New separator with specific treatment to limit ageing

New hydrophilic treatment to improve electrolyte retention during ageing

Short-circuit prevention

Life duration improvement


R&D Ni-MH Program Back up and Telecom

Cells design optimisation


Positive Electrode: Foam electrode

1. specific NiOH2 coated with Co(OH)2

2. Cobalt oxidated in-situ:

Co(OH)2 => CoO(OH)

Negative Electrode :

Specific AB5 alloy composition for long

life duration

Additives to reduce alloy corrosion

Separators:

New PP separator with

innovative surface treatment to

optimise electrolyte retention

Electrolyte:

Ternary electrolyte K / Na / Li

(high T°, Cobalt stabilisation)

Jelly roll:

1. Optimised mechanical

design to increase electrolyte

volume

2. Laser welding

ecolife MH range: 2017

Accelerated ageing test 10 months @ 80°C permanent Application = 10 Years at 40°C

R&D Ni-MH program Solar


New VHT technology: 2018

10 000 cycles @ 50°C permanent

Conclusion

Preliminary results

20

High temperature behavior – New Ni(OH)2 material

Up to 90% charge efficiency at 70°C on R&D material

Ni(OH)2 material coated with Co(OH)2 or CoO(OH)

Both useable in ARTS Energy cells

Alloy development

AB5: Cost reduction program to reduce Nd and Pr on-going

A2B7- RMgNix: low temperature OK, cyclability OK, cost issues

Separators

New PP separators for higher electrolyte retention technically qualified

Industrial ramp-up in 2017


Conclusion

Product Road Map

21

ARTS Energy’s NiMH used in very high demand applications

Solar: high Temperature (middle east)

Improved life duration (TCO optimisation)

Emergency lighting:

High temperature + long life duration (products with no maintenance)

New Product Introduction

2017: ecolife MH range introduction (ELU) 10 years life duration at 40°C

2018: New VHT technology for solar 10 years in hot countries (Middle-East,

Africa)
