Ann: Altech - Share Purchase Plan, page-4

The announcement on 25/11:

• The previously unresolved impediments for using silicon in lithium-ion battery anodes which are: silicon particle swelling; prohibitive first-cycle-capacity loss of up to 50%; and rapid battery degradation, appeared to have been substantially overcome
• Altech batteries demonstrated good stability and cycling performance

Todays SPP announcement:

• The previously unresolved obstacles for using silicon in lithium-ion battery anodes were silicon particle swelling; prohibitive first-cycle capacity-loss of up to 50%; and rapid battery degradation each charge and discharge cycle, were resolved.
• Altech batteries demonstrated extremely good stability and cycling performance over extended periods

Just a play on words, a pump for the SPP, letting a bit more information slip, or both?
I'll go with both.
